Dermatologist Questions Discolored nails

Is nail discoloration a sign of a health problem?

My nails are thickening and seem a little discolored. I have no other symptoms, or really feel differently. Could this be a health problem?

Without seeing it, it’s difficult to answer. Thickening of nails can be related to poor circulation or fungus. Discoloration can be related to skin color. Development of an early mole under the nail, beginning of a fungal or bacterial infection or even a melanoma.
Fingenails or toenails or both? Nail thickening and discoloration can be due to several issues -- most of which are harmless and more an "appearance" issue. However, if the appearance bother you, you should get it evaluated.
