This article will tell of some other diseases and disorders that our fingernails can warn us about so we can go see a doctor for further evaluation.

White lines across the nail may also indicate liver disease. A half white nail with dark spots on the tip could indicate a kidney disorder.

Abnormally thick nails might be due to the blood not circulating properly in the vascular system.



Yellow nails can mean there are problems with your liver, diabetes, respiratory disorders or problems with the lymphatic system. Yellow nails can occur many years before the disorder shows up.
