Finger nail splitting and hypothyroidism
Posted , 18 users are following.
Hello, I have been hypothyroid for over 20 years. Years ago I started to notice a problem with my left thumb which would keep splitting vertically.
Over the years it has spread to about 5 of my fingers at different times. I have to keep nails shorter than I would like like but they still split. Just be chance the other day I read online that vertical splitting is caused by under active thyroid. Anyone have this same problem and have you found a solution. Thanks.

I was diagnosed as hypothyroid a couple years ago, and now think I was hypo for close to a decade before that. My nails were brittle too, but that wasn't as bothersome as my thumb nail splitting. When I started taking levothyroxine and Vitamin D, the split healed and my nails grew too long for the first time in many years! I wasn't quite "right" on T4, so I switched to Armour (still on same dose of Vit D), and the split came back, so now I'm online trying to figure out why. I won't go back to T4-only because I like having my brain work again, but I'm taking my split nail as a sign that I'm still not 100%. One thread suggested it's from a Vitamin B12 deficiency, and recommended 1-5 gm of B12, sublingualy, in the form of methocobolamin. I'm going to give it a try until my next doc appointment when I'll ask her about my Armour dosage. I hope it works... for all of us!

Libralady, I was blaming menopause for my symptoms too, but when the fatigue took over my life and I was shivering under a blanket in August in Arizona, I figured it was more than that! Interesting about your aunt having pernicious anemia! Did she have splitting nails too? The woman behind "Stop the Thyroid Madness" (STTM) set up a deal with a national lab in the US to get testing done on our own (since docs who are truly knowledgeable about hypothyroidism seem to be so rare), and she's got a B12 deal too.
BTW, STTM notes that stomach acid production inhibitors (antacids like Prevacid and Prilosec) can make you anemic by decreasing absorption of B12.

In case that post gets tossed, one point that might affect you is that some antacids make people anemic by decreasing B12 absorption. The ones that decrease production of stomach acid are worse than the ones that neutralize acid.
Crossing my fingers that the moderator sees value for others in my link! If not, look for Stop the Thyroid Madness (STTM) for loads of information on hypothyroidism. For those in the US who haven't found a knowledgeable doc yet, STTM set up special lab pricing so you can get the labs done that you need for a proper diagnosis.They also have a reduced price on B12 lab testing.

I am in the UK so thank heavens for the NHS even though it gets a slating about waiting times etc it is still free at point of need. I also know the controversy about hypothyroidism and under diagnosis and under
treatment. I am sure you know what I mean. I was interested to hear you take armour. Let me know how you get on with any change to your dose.
Take care

There is obviously a connection somewhere and maybe one day the medical profession will treat people as a whole and not send them off to different specialists. Maybe that sounds all a bit too simple but I am sure you get what I mean.

Sorry for the delay in responding. Got busy at work, which is a good thing when you're self-employed and your thyroid meds are working to get you through the day without a nap!
I think you are right about the autoimmune problem. I've tested negative for Hashimoto's, and I don't have IBS, fibromyalgia, etc. that others have. I have a friend who is also hypothyroid who has RA and fibromyalgia. Now you've got me curious if she's got Hashimoto's.
I wanted to get back to you and let you know that I had some sublingual B12 that I started taking... and the split in my thumbnails went away! I guess I'll only know for sure if it was the B12 if I stop taking it and the splits return, so I'll get back to you if I try that. The pills are 2500 mcg (2.5 mgm) of methylcobolamine and are marked as suglingual.
I totally agree with you in hoping the medical profession figures out how to treat us as a whole. And, I hope there is change in treating thyroid disease. There are too many of us suffering because our lab tests look "normal" but doctors are afraid of being "pioneers" against what they learned in med school. I just hope enough docs saw the article about the hypothyroid person who woke up in a Milwaukee morgue last month because he'd gone into a hypothyroid coma and appeared dead. Maybe then they'll understand that our fatigue is not psychosomatic!

Yes. My nails are doing same thing badly. Started few wks ago. Have been on low dose Levothyroxine and was increased from 25 to 50 mcg. and then back down. That's when my nails std to do this. B4 medic. I had no nail prob. They were strong and grew long and fast. But blood showed I was a bit over the guidelines so Levothyroxine was given. Wonder if I sh increase back up to 50 mcg. Is it harmful to switch dose back and forth? I've had to cut my nails SO SHORT that I'm nearly into the quick of nail. The ridges are VERY prominent and one nail is actually splitting OPEN vertically. Not using polish. Taking vit d3, calcium, vit power c, mult. vit. Don't know what to do.

Hi Libralady13
I also have an under active thyroid and while my nails don't split in the way you mention they do have vertical ridges. I've never thought it was due to my thyroid, just poor diet but now I wonder. Ha, as if now I'm going to do something about it. Actually I've been going to for a while but will I? Nope.. Well I might just give some of the tips that have been mentioned on here a try..

Hello I can't offer you any advice other than moisturising the nails to stop them drying out and drink plenty of water. Mine are no better and whilst it started with just one thumb over 20 years ago in now affects both thumbs and nearly all fingers. I have just accepted it and keep them short. I have some other health problems and tests coming up so they are occupying my mind now I have just had my thyroxine reduced from 125mg to 100 after many years on 125 don't think it is making anything difference to the nails though both the ridges and splitting. Hope you can find something to help let us know if you find anything helpful. I did think about having false nails but that would probably make existing nails worse and of course the cost being on a pension. Take care and best wishes to you.

Hi Libralady13,
I have Hyperthyroid and my fingernails were split & cracked badly too. I used 1 teaspoon of coconut oils and 1 capsule Omega3 mixed together and rub on my fingernails after every time I washed dishes and before bedtime. Its really help though. Please let me know does it works on your fingernails. Cheer.
