How can I get my fingernails to stop curving?

As my nails grow longer they start to curve. I have to keep them short so that the curve is not noticeable and to keep the nails from going into my finger tips. My fingers are normal, not swollen.  I have stopped wearing nail polish.  My nails are not splitting, brittle, dry or fragile, they just curve.  The nails look pink and some of them have vertical ridges. I have had ridges in my nails for as long as I can remember.  This curving issue developed about two years ago.  Is there anything I can do to stop them from curving?

    I would recommend seeing a dermatologist(yes they are more than skin)Smile Don't panic however..it could be an underlying cause(not necessarily serious) but please get it checked out just to be sure ok?

    curved nails could be a sign of nail clubbing. If the tips of your nails are curving downwards, and they feel soft when you press on them, you may have clubbed nails.

    One way to tell if your curled nails are due to clubbing is to do the Schmroth's test. Put the backsides of both hands against one another so the fingers of each hand are pressed against one another. If you look at your fingertips from the side and see a diamond-shaped opening between the nails, your nails are clubbed.

    What Causes Nail Clubbing?

    Curved fingernail due to clubbing are sometimes, but not always, caused by an underlying medical problem. They're most commonly seen in people who have chronic heart or lung disease, although other conditions such as thyroid problems, inflammatory diseases of the digestive tract and liver disease can cause clubbed nails too. In six out of ten cases, no cause can be found for fingernail clubbing, and it probably represents a normal variant.

    What Should You Do if You Have Curved Fingernails Due to Clubbing?

    If you have curved or clubbed nails, they should be checked out by a doctor to make sure it's not due to a medical condition. Most doctors will do blood studies, a physical exam and a chest x-ray to look for medical causes of nail clubbing. If the work-up is completely negative and no medical problems are found, no treatment is needed. Clubbed fingernails aren't uncommon in healthy people.

    Curved or Curled Fingernails: The Bottom Line?

    Curved fingernails are usually due to clubbing of the nails, which may or may not be due to an underlying medical problem. If your fingernails are curled or curved, see your doctor for a check-up.

    Good luck and please let us know how it works out..Stay beautiful and Take care.

    Thanks for answering.  I did ask my Internist about my nails and he said it was nothing to worry about.  He did put me on a thyroid medication about a year ago, but gave me another reason for the medication and did not mention that my concern about my nails had anything to do with putting me on this medication.  No change in the curving fingernails since I started this medication. 

    Saw  a dermatologist about a month ago and there was no mention about my curving nails.  However, I did not bring this up to the dermatologist.

    It is very possible that it could be the thyroid meds...Did you notice when they started curving...before or after the thyroid meds? It is always good to keep a health journal/log to remember any changes for anything/everything..Periods, breasts changes, hair, nails, skin rashes, etc., Keep us posted! Take care.

    I used to have very long beautiful natural nails.  Now I have to keep them short due to the curving of some of the nails.  Maybe bettyliem is right -- aging.

    Wow...talk about mis-information... Whoever wrote the reply to the question was 100% WRONG! The test is called Schamroth sign test and the diamond means your nails are NORMAL not CLUBBED. Really makes you wonder about the internet when you read comments from so-called Drs....

    I've also read it may be a deficiency in B12 or iron. I'm going to try those first before going to my doctor or a dermatologist. I've also had this nail curling for a couple years now & I used to be able to grow beautiful strong nails that everyone would complement. I now also have to keep mine short because of the curling & it seems I'm always using an emery board on my nails. Cry

    Seriously talk about fear mongering! Shamroths' window is a test that is used in certain cases to determine if a person has clubbing or not. The diamond shape or window is present in most healthy people. It does depend on what the person asking the question means by curving vertical ridges (as in from cuticle to tip) are usually a sign of aging or nail trauma (in my case trying to snap off fake nails...ouch). Horizontal lines can be a random blip, to heart failure, to a mild fungal infection. If you are worried ask your doctor it is what they are there for and it never hurts to ask...(unless you are Oliver Twist)
