It is common to feel low on energy and lose your appetite after a long course of antibiotics because they can disturb your gut bacteria. A simple approach is to eat light, easy-to-digest foods and add probiotics (curd, buttermilk, probiotic sachets/tablets) to help your digestion recover. Stay hydrated, take small, frequent meals, and avoid heavy or spicy foods for a few days. If weakness or loss of appetite continues for more than a week, get a check-up.

If you have chronic indigestion and appetite problems, it is advised to consult a doctor. The doctor will check your condition and prescribe suitable medications.
