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.
Iron deficiency (Anemia). Anemia or iron deficiency may also be an underlying cause of cracked nails. Iron helps the body in producing hemoglobin, the oxygen carrying part of RBCs. A deficiency of iron can lead to cracked nails for the blood oxygen does not completely reach the nail bed.enerally, maximum non-medical causes of cracked nails are associated with over exposure of nail to harmful chemicals and water. This leads the nail to lose the moisture barrier and natural oils. Many times, low humidity levels in winters plays an imperative role in robbing the essential moisture from nails.
