vitamin B12 deficiency. This vitamin plays a vital role in red blood cell formation, nerve function, and DNA synthesis. A lack of B12 can lead to a condition called vitiligo, where the skin loses its pigment, resulting in small or large white patches.
People who follow strict vegetarian or vegan diets without proper supplementation are at higher risk of B12 deficiency. Symptoms may also include fatigue, numbness, or tingling in the hands and feet.
