11 Health Warnings Your Fingernails May Be Sending

You may not look very often at your fingernails, but did you know that your fingernails can tell you a lot about your health? Did you know there are hundreds of medical conditions and diseases that may cause nail changes? Your nails can show the history of recent health and physiological problems, and has been used as a diagnostic tool since ancient times.

Sometimes it might be a fungal infection or injury, but your fingernails can sometimes indicate a more serious underlying problem, such as problem in the liver, lungs or heart.


The Half Moons at the Base of your Nails

When the nails are healthy, they have a pink color and the moons near the nail base are light pink to white color. According to Dr. L Reed, ND, the half moons at the base of your fingernail is an indicator of good thyroid health. Each nail that is missing a half moon indicates a weaker thyroid. Weak thyroid can lead to mood swings, depression, thinning hair as well as other symptoms.

The Nail Texture

Healthy nails are smooth, without ridges, grooves, spots or discoloration. But what happens if you see that your nails have changed in color, shape, texture, thickness or any other unusual growth pattern, and you don’t know the reason for that? Well, maybe it’s time to visit your GP.

Here you will learn how to read the signs on your nails and discover the secrets they tell you about your overall health:

1. Brittle or crumbly nails

Brittle or crumbly nail can be a result of aging or a long exposure to detergents or nail polish, but sometimes it can indicate a fungal nail infection, Lichen planus (a condition that forms an itchy rash on the skin or in the mouth), thyroid disease or psoriasis. In rare cases it can also may be an indication of a Reactive arthritis which is a painful form of inflammatory arthritis.


2. Discolored nails

Yellow nails can occur due to a long use of nail varnish, but can indicate fungal nail infection or psoriasis. It can also indicate several other ailments, such as: jaundice due to liver problem (also see my other post about early signs of liver damage), sinus infection, a problem with the thyroid gland, lung infection and lymphedema (fluid retention that generally occurs in arms or legs). For more information, read my article about the most common causes of yellow nails.

Green-black nails – indicate bacterial infection that usually occurs under loose nails.

Bluish or purple fingernail beds may indicate oxygen deprivation.

Grey nails – can be caused by certain medications.

Brown nails – can indicate a thyroid disease or malnutrition. Fingernails that are half white at the bottom and half brown near the tips can be a sign of kidney failure, AIDS or appear after chemotherapy.

White nails – might be a sign of aging, fungal nail infection or iron deficiency (anemia), as well as other range of ailments, such as: cirrhosis (scarring of the liver), kidney or heart failure, diabetes, hyperthyroidism, malnutrition or after chemotherapy.


3. Thickened nails

There are a few reasons for having thick nails but they are commonly caused a fungal nail infection, but can also result from psoriasis and reactive arthritis (a painful form of inflammatory arthritis). Yellowish, thickened, slow-growing nails can also indicate lung diseases.

4. Loose nails

When the fingernails become loose and can separate from the nail bed, it may indicate an injury or infection, as well as thyroid disease, psoriasis, poor circulation or allergic reaction to medicine.

5. Spoon-shaped nails (koilonychia)

When your finger nails curve inwards and look scooped out, it may indicate iron-deficiency (anemia), hemachromatosis (liver condition which results in iron overlaod), Raynaud’s disease (that affects the blood supply to the fingers and toes), heart disease and hypothyroidism.

6. Pitting or dents on the nails

Pitting or small dents on your nails can indicate psoriasis, eczema, reactive arthritis, and alopecia areata (hair loss due to autoimmune disease).


7. Grooves across the fingernails (Beau’s lines)

If you notice deep lines or grooves that run across the nail, it might be a result of having chemotherapy, a previous injury, exposure to cold temperatures, Raynaud’s disease that affects the blood supply to the fingers and toes, diabetes, vascular disease, zinc deficiency and illnesses associated with a high fever.

8. Nail clubbing

This is when the fingertips and nails are unusually curved around the fingertips. It can be harmless due to increased blood flow to the fingertips, and can run in families, but if it suddenly occurs, it may indicate low oxygen level in the blood that can indicate lung disease, as well as other ailments such as heart disease, inflammatory bowel disease (IBD), liver disease and AIDS.

9. White lines running across the nails

In this case the lines run parallel to the base of the fingernail. Don’t confuse it with white spots or streaks that are normal, but when there are parallel white lines across the nails, it’s a sign of low levels of protein in the blood, which can be due to malnutrition or liver disease.

10. Dark stripes running down the nails

This is common among black people and in most cases it’s normal. However sometimes it may indicate a skin cancer that affects the nail bed, called subungual melanoma. Generally, this type of cancer only affects one nail.

11. Red or brown little streaks under the nails

These are usually lines of blood caused by tiny damaged blood vessels and are called splinter hemorrhages. This is nothing to worry about, but if many nails are affected, it may indicate another underlying disease.

Don’t ignore your fingernails and the health signs they indicate. Have a closer look at you nails more often to keep an eye on your health. Your nails and your overall health are closely related and offer you a window into your health.

    I need all the help I can get !!

  2. dimaks says:

    I never thought those signs of the nails can be quite scary. The only thing I know is that long nails can be places for germs to lurk in. But thanks for this well-explained list.

  3. chris thorpe says:

    What if my nails split, down the middle, like a sunfower seed? My grandmas do, too…?

    • Jenny says:

      I’m not sure, but perhaps next time you visit your doctor, show it to him/her and see what he/she thinks. The most common reason for developing splits and cracks is due to repeatedly wetting and drying your nails but. Another less common possibility is nutritional deficiency, so it’s best to show it to your doctor on your next visit.

    • Tina Ward says:

      My nails have ridges and splits from the tip to the base. I always had long healthy nails until I had a gastric bypass. It is a nutritional defenciency but I haven’t been able to narrow down which vitamin. I’m always anemic and B12 deficient and I take shots for B12 and iron pills but they haven’t fixed the problem. Multi vitamins don’t help either. So, short of having a full spectrum blood test for all possible mineral deficiencies which would be expensive and so far my doctors don’t want to do it since it’s not life threatening.

      • Erika says:

        I have the same problem, very distressing as I feel very ashamed of my hands and nails. I take lots of vitamins and am generally healthy. I have very long thick healthy hair, but my nails always thin, ridged and split. No doctor or chemist has been able to suggest a solution. They say it’s hereditary. My dad and grandmother had it too.keen to hear if anyone has any thoughts? Best thing I’ve tried is keeping nails out if the water and using coconut oil regularly.

        • Tanya says:

          I put a mixture of vitamin e oil and tea tree oil on my nails twice a day. Apply with a q-tip and let dry naturally. Your nails will strengthen and will stop splitting. Two capfuls of vit e oil and 1 of tea tree.

        • Maria says:

          Use Garlic, cut it in half, rub it on your nails once or twice a day. It makes your nails stronger and healthier. And always add Garlic into your cooking.

      • Laurie says:

        contact me and I will help you

        • nancy says:

          ok so I have had many different health issues over the years, I just had major spine surgery a few months ago however for the last several years I have had this uncomfy pain in my hands from the wrist to the finger tips. its not carpal tunnel as I have had that surgery as well, its different from that, its only after I wake from sleeping that I have what feels like but not so much looks like really swollen hands and fingers mostly , they feel tight and it hurts and is now become pretty impossible to make a fist with the right hand and some what the left so I wasn’t sure if the nail issue was the reason of the hand problem or something worse…I woke to find my nails had a redish color to the thick lines basically near the cuticle I have a white moon shape with a thick kinda redish line that is right above the whitish moon and another whitish thick line of white and then a redish line above that white which is right at the edge of the actual nail bed where the nail just starts to grow out..the white areas are kinda whitish redish but mostly white and there are the 2 lines of red so all together 4 lines divided from the cuticle to the top of the nail bed… does this mean anything since I have read things like, liver issues, heart issues , renal failure or simply rheumatoid arthritis can you help please

          • Gail says:

            Did you ever receive an answer to your finger nail question? I’ve just noticed I have the identical description in otherwise very healthy nails. I do have degenerative arthritis, surgery not yet indicated

        • Cindi Avery says:

          Please contact me! I need your help! My nails split, have ridges and the whites have suddenly become deep and damaged looking. Thank you! I look forward to hearing from you!

        • Pam says:

          Will you help me with nail splitting? How do I contact you?

        • Sharyn says:

          How can you help with ridges on nails pls

      • Carla Bates says:

        sounds like iron deficiency. I had the same problem then found i was very anaemic. I was on ferrous fumerate 3 a day for 3 months…prescribed by GP and hey presto my nails are sorted and my iron levels are normal again.

      • Monica Ferguson says:

        The ridges in the nails are from parasite infection. Most commonly pin worms, round worms and thread worms which is found in foods we eat and the body doesn’t eliminate all of them. The parasites affect the nerve endings causing anemia and so on. Keep taking the b12, do a cleanse and you will notice a change in your nails bedso in about 6-8 weeks.

      • cissi stanley says:

        magnesium is what you need !!

      • Connie Harris says:

        Chris .I just got back from a seminar on tongue and nail analysis .The split nail could be a heart problem or mal- nutrition .

      • Robin says:

        I am in the same boat. Have your Dr check your thyroid also.

      • Monika says:

        Since our soil is depleted due to chemicals such as round up or other chemical fertilizers You might consider Adding a liquid trace mineral supplement to your diet. They are inexpensive and I have found them online, since Using them for a thyroid disorder. Many people are suffering iron, magnesium, zinc, potassium and various other trace minerals that are needed to transport the nutrients to the blood cells. Vitamins alone are not sufficient, I encourage anyone reading this to research your symptoms and adding either a particular mineral or a combination trace minerals. Also you should add Celtic salt or pink sea salt to your diet, since they both contain the natural minerals! Avoid table salt since it’s hydrochloride and really bad if you have high blood pressure. Your body needs salt, you sweat salt, you cry salt, you go to the ER and one of the first things they give patients is Saline (salt water) but it has to be the right salt!! Celtic salt incomes in a blue bag its higher in magnesium, so if you suffer from headaches, leg cramps, or feel fatigue, put a couple of grains of the grey Celtic salt on your tongue and then drink your filtered water. Your cell receptors will be able to open up and receive water to hydrate your body. You feel better quickly! God bless you and good health to you!

    • Shirley says:

      Pleas please, discuss TOENAIL problems!! I have thick toenails, all 10 of them!! They also hurt very much. I can hardy do any walking with shoes and/or socks on. I have been to a Podiatrist twice and they did test and determined it was NOT a fungal infection. However, they do not know what it is or what is causing it and I continue in pain. I am so distressed and don’t know what to do next. Can you help me, I’m desperate!!

      • Ted says:

        Psoriasis! Contacr a dermatologist.

      • Naomi says:

        I had stabbing pain in the middle toes of both feet. Finally was diagnosed with Psoriatic Arthritis. I have had arthritis in my hands for years. Have been taking two turmeric capsules and one tart cherry capsule daily for about eight months and it has lowered my inflammation level and really reduced the pain.

  8. Marion says:

    Hi,,,I was recently diagnosed with Lichen Planus but no information from the Dr,,Its very itchy ,,I have noticed I am having so painful spots, on my thumb. Now have painful area just under my breast,,ribcage area..right side…can you give me any info to help me please,,,,so greatly appreciated…

    • Jenny says:

      Hi Marion, there is no cure for Lichen Planus, and treatments are available to help manage the symptoms and make living with it easier. It is mentioned in NHS website that most cases of lichen planus clear up on their own within six to nine months. The rash rarely lasts longer than 18 months. You can have a look at these websites where you can find more information about conventional treatment and lifestyle changes:
      Mayo Clinic – – browse between the pages
      NHS website –
      Medicinet website –
      Read these sources to get a better understanding about your condition and treatment options. Mayo clinic for example suggests applying aloe vera, cold compress or having colloidal oatmeal bath.

      • Darlene McKerral says:

        I have Lichen Planus for the last 8 years. It was so bad that I did not want to live with it any more. It was all over my body, my legs were the worse if I could show you a photo of them you would understand.. Yes I even had it there ….that area I refused to have the doctor treat. I had to have cordison needles every month, they would give me 10 shots every time I went in. They would stick the needle under the skin to all the worse ones first then go from there. I had a medicated cream to use between visits. I still have it once and awhile and not as bad thank goodness. The scares from it are still there.

      • Wilhelmina Thompson says:

        Hi Jenny, I have Lichen Planus. Haven’t had a flare up in 10 years. God I had it bad all over except face. Black spots was alful. Was put on steriod cream and this aweful pill.told doc I was moving to Florida he said good. Lay out in the sun 3 times a day protecting the face no cream, no pill, for 20 min three times a day. Stopped the meds couldn’t take the side affects. Used the cream out of the sun. I sware with in 4 months all went away, no scars. Haven’t had a out break since. Really don’t know what happened.

  9. Laura Beauman says:

    My 13 yr old grandchild has had a nail condition tha resembles spoon nails. The Drs have run tests and can’t find any explanation for the condition of the nails. I feel really bad for him. He has had this condition or several years.

  10. Rachel says:

    I used to bite my nails, age 3-12. I quit and my nails never looked right. My dad has punished me since I was 3 for ruining my nails. After he passed away I learn it’s an iron deficiency. All that time spent making me feel bad for nothing. Meanwhile, my 40 year old sister who still bites her nails will sometimes go a week without biting and hers grow out perfect. Darn!

  11. Brooklyn Sanchez says:

    It was impressing indeed and informative too… I’ve been a follower of your page so I make it a habit of reading your articles here.. They are so helpful and adds more knowledge too.. Thanks!

  12. Winston says:

    Very interesting and informative. But based on just description, it can be confusing and easily misunderstood. What’s missing are pictures to support what you are describing.
    Ie: White lines running across the fingers. Do you mean vertical or horizontal lines?

    • Jenny says:

      You are right that pictures would have passed the message much better than words. The reason I didn’t put pictures is due to legal issues and rights of using pictures that are not mine. As for your question – the lines run parallel to the base of the fingernail – I will add it to the post – thank you for that!

  13. Alison D says:

    I have brown lines on some of my toe nails and on all of my finger nail HELP. Ive had them for 30 plus years.

    • Jenny says:

      Hi Alison, although you had it for such a long time, for your peace of mind show it to your doctor on your next visit to see what he/she thinks.

    • Connie Harris says:

      Allison If the lines are vertical , it could be internal bleeding or increased risk of melanoma cancer.Something to look at.

  14. lucy says:

    hi i noticed u didnt mention if the white doesnt show on ur nails? only my thumbs show the white 1/4 moon thingy near cuticule. what does that mean? plz help as i heard something on doctor oz once n i cant remember thanks so much

    • Jenny says:

      I’m not really sure Lucy. It might be nothing to worry about but for your peace of mind show it to your doctor on your next visit.

    • Lovedove says:

      You want moons on the nails. That means good oxygen flow. No half moons means low oxygen or sluggish blood flow.

      • Adele Lopez says:

        Hhmmmm…my whole life..66 years I have never had half moons on my nails…I have always been Blessed with a strong healthy body and I can’t remember the last time I even had a common cold…I am around runny noses and other illnesses daily with grandkids and owned a daycare center previously..but my immune system stays strong…I’m a tea or water drinker soda or liquor or tobacco…I eat anything and rarely sleep more than 5 or 6 hrs a nite…and only an Aleve if Ive overworked outside to take away soreness.otherwise no meds.I don’t know my family health history so I don’t know if I inherited the naked nails…so tell me, am I doomed because of this…or just plain Lucky?

    • Casey says:

      Lack of white moons is very common among people with thyroid disorders. Have your Dr run TSH, T4, T3 and RT3 tests.

  15. joan liegey says:

    my nails were breaking and had ridges in them. I had my iron checked and it was rock bottom. had to have iron iv’s but it didn’t help. found out I had cancer. so far all is okay. but I know keep a check on my nails and iron.

  16. Lori says:

    My 25 year old Son has just developed a nail condition that does not lok like any of the one’s you mentioned. His nails are crackly and dry and have come off. his skin under the nail is shriveled and deformed. He has no pain but the nails fell off. It’s on several fingers not all. The doctor told him not worry about it. But this looks unsightly and a nail completely crumbling off is serious to me. Can you help?

  17. Carole says:

    i have very white nails. I only have half moons on my thumbs why it that? I have had low iron at different times in my life. My nails are thick and healthy I think.

  18. Sha in GA says:

    What about deep vertical lines that run from the base to the tip?

  19. Doe says:

    Both my thumb nails are messed up. One I have a huge ridge in the side, the other has a crack from the base to the tip. I have psoriasis and arthritis in both thumbs. Looking at them, where the most swelling from arthritis is, is where the nails are abnormal. It’s pretty tough to keep them moisturized or dry. I am a hair stylist.

  20. Yvonne says:

    I have two light brown stirpes on one index finger and another one on my other index finger. What could it be?
    Everything I ve read sounds scary. Please help. Thank you

    • Jenny says:

      Hi Yvonne, I’m not sure what it is, but don’t panic, just show it to your doctor on your next visit – It might not be something to be worried about.

  21. paula says:

    I have white patches under my nail that go pink when pressed but also cold hands any suggestions? Thanks

  22. Pamela says:

    About 4 months ago I noticed that the tip of my nails turn brown, very brown that its almost black in colour, even when I cut all the nails off, when it grows, it gives the same result, white under and dark brown at the tip, what kind of disease is causing this Plz?

    • Jenny says:

      I’m not really sure Pamela (I’m not a doctor). Show it to your doctor on your next visit.

    • Fran says:

      My nails are doing the same. Normal white/pink on the bottom & brown on the top/tips. I have been to several doctors & they do not have an answer. I just read in this list BROWN NAILS that it could be from chemo. I have not had chemo but I have been taking a chemo drug (methotrexate) for RA for about 8 years now. My hair dresser had told me that all drugs come out in your hair and/or nails. This is the best answer that I have gotten since it started.

  23. ken says:

    my nails were white but now they have changed to red and white .what causes that??

  24. Han EuJi says:

    Hi, I wondered what would be the reason for a sudden turn in the colors of fingernails, and that too only ooccured to one hand only instead of both? Because my fingernails on my right hand just suddenly turned pink this morning when all my nails were always pale purple before. Easier said, now it’s: left (pale purple) VS right (bright pink). Help me~

  25. sheryl says:

    please I need help?

  26. Ben says:

    My nails are partially white near the base. I can’t see through my nail to the nail bed because of this whiteness. Anyone else have this? Nail beds are supposed to be a nice healthy pink color

  27. blu says:

    a lot of nail symptoms is caused by vitamin B12 deficiency

  28. Amy says:

    I have a sort of like a bump or what looks like a bubble thats formed under my nails right in the center of all my nails. ALL of them. There is a faint white line running parallel on some of the nails with it. Could it be iron deficiency or maybe calcium build up? I’ll still ask my doc but if you have any good guesses that might help point me in the right direction it would be great.

  29. Tracy Chastain says:

    I have light purple nail beds on all nails but not the whole nails and the rest of under the nails are white! I am also going through pre-menopause and I don’t smoke, drink and the only pharmacy medicine I take is antacids! I’m a bit concerned about what the purple and white nail beds could indicate!

  30. jedza says:

    Hie what about mine they turned brown just below at the base, what could be the cause

  31. Lia Pierce says:

    My 6 year old son has small white lines on some finger nails,long ridges from base of nail to the tips of almost every finger and pits on some nails. Both of his big toes have big cracks from base to tips and turn inwards at the edges like ingrown toenail. He’s an extremely picky eater and I’m afraid it’s negatively affecting his health.

  32. preet khehra says:

    i have no moons on my nails
    is it harmfull?

  33. Chidinma Ojiegbe says:

    I have no half moon on my nails,does it mean they’re not healthy? And it breaks off on its own when long.

  34. Julie Anthony says:

  39. JUST CURIOUS says:

    Why don’t most DOCTORS look at patient’s nails during exams?

  40. anamika says:

    I am great nail biter and my nails skin is broken as well and sometimes it bleed too.
    Any remedies please contact me..?

    • Jenny Hills says:

      Hi Anamika, the real remedy to solve the problem from the root is to stop nail biting. As long as you continue with this habit, you will have broken skin around your nails. Unfortunately I know too well your problem as I battles nail biting for a long time trying different bitter nail polishes to deter me from biting my nails, but to no avail. I even tried covering my nails with band aids. I knew that once the nails would grow, I wouldn’t want to ruin them, but how can you get to this stage? The only thing that worked for me was to glue fake nails over my real nails and wait until my real nails grew longer. Once it happened, I didn’t feel anymore the urge to bite them as I didn’t want to ruin the good results. The fake nails also prevented the problem of broken skin as biting the real nails was impossible. I can tell you that after years of nail biting I don’t have this problem anymore!

  41. Darlene Martin says:

    I’m desperate at this point. I have been ill for almost three years, doctor kept sending me home with antibiotics and Ibuprofen. Was recently diagnosed with H-pilory and after two weeks of very painful treatments, I was informed treatment didn’t work so had to go on a double treatment for seven more days. I still have problems, severe stomach pain, vomiting, diarrhea, fatigue clammy sweat chill disoriented dizziness and leg cramps that wake me in the night. I have been prescribed so many different medicines in the past year and nothing is helping my issue
    I was washing my hands just moments ago and noticed the white moon on all fingers including thumbs, but they are outlined with a dark purple line right on top, from side to side, then my nails look like they are turning light brown where they used to be pink. I’m started to think my doctor has been using me as a Guinea pig. I have stopped taking all my medications as of last Wednesday when after I prescribed Augmentin and my symptoms became worse, I called my doctor for three straight days asking for advice only to be told I would receive a call back with two hours and lm stilll waiting for just one call back. Am I over reacting or can you give me some advice on what I need to address with my doctor tomorrow when I go in for a body Scan.
    Thank you so much,

    • Jenny Hills says:

      Hi Darlene, you can read my article about H. Pylori, but since I’m not a doctor, I’m unable to give specific advise. I don’t think you are over reacting as this is your body and your health. I believe that if you don’t trust your doctor or unhappy with the treatment you receive, you may benefit from having a second opinion from another doctor who can look at your case with a fresh look.

  42. Kathleen says:

    Between the half moons in my nails disappearing and my hair loss, I must have a thyroid problem. Once the thyroid is back on track, how long does it take for the half moons to reappear?

  43. J says:

    I have read where clubbing can also be from mold exposure. A good detox is necessary along with removal of mold exposure source or remediation

  44. Ann says:

    How can I solve the problem with my nails if they all do not have half moons? Do I need to consume more iodine?

  45. Sherif says:

    Very useful article. Would have been better if accompanied by some photos to show the case you are talking about.

  46. Sally says:

    Please help all my nails u cannot see the moon just white like half and half but some look like Terry nails I was told it could be cancer my friends r all noticing it and saying something is going on with u internally ~ I have low back pain it’s bone on bone disc is gone with pain in groin thigh and butt someone told me it could be all related any help would be greatly appreciated seeing dermatologist again cause when he first saw me he said he’s never seen anything like this

    • Jenny Hills, Medical Writer and Researcher says:

      Hi Sally, don’t listen to people who frighten you with cancer. While nail changes can serve as an important clinical sign for underlying systemic disease, you need a professional medical consultation from a doctor. I’m not sure if dermatologist is the right person to go to. Perhaps your family doctor would be a good starting point.

      • Sally says:

        The doctor told me it could be cancer and I wanted to scream well biopsy my nail and find out drives me crazy try this cream and that just do the biopsy

    I only have the half moon on my thumbs, not my fingers.

    My nails have always been healthy but I noticed that my thumb nails have pink inside the white , is this normal?

      Hi Ava, I’m not sure what it is, but if the rest of the nails are fine, then probably there is nothing to worry about. Perhaps on your next visit to your GP you can show it to your doctor if they are still there.
