Hi, I have gone through your health problem carefully and understood your concerns. It could be great if you could send a photo of your nails so I could evaluate myself the changes there before running into final conclusions. Anyway, from what you are reporting, if your nails are similar to Terry s nails, it means that the bed of nails is not supplied sufficiency with blood. There are many health problems causing this including: - problems with liver, heart, kidneys (can be excluded through liver/kidney function tests and cardiac check up) - anemia - thyroid problems (can be ruled out by thyroid function tests) - fungal infection if metabolic diseases are ruled out. As you may see, there are several tests and a good clinical observation needed before determining the right diagnosis. So, I can suggest to consult with your dermatologist and run the suggested tests for appropriate treatment and management. Hope it was of help. Dr.Albana
