Finger nail splitting and hypothyroidism. 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.
