Since last December, I have experienced headaches, eye pain, weakness, and occasional abdominal pain. I recently changed my diet to gain weight. Could this be the cause, or am I simply feeling depressed?
It is unlikely that your persistent and varied symptoms are caused solely by a change in diet or by simple depression. It is important not to self-diagnose. Please consult your doctor for a proper evaluation to rule out any underlying medical conditions and to receive appropriate guidance.
