I have a bad appetite, i eat less, i'm a vegetarian, i feel weak, please tell me what to do? thank you.

Mineral deficiency?: Accutane can cause poor appetite and fatigue; it's a powerful drug. There are less dangerous treatments for acne. Vegetarians often become deficient in zinc and low zinc can cause low appetite. Try taking a quality multivitamin and perhaps extra zinc as zinc picolinate. But please see a doctor for an evaluation as there are many possible causes for your symptoms such as anemia or parasites.
