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.

Feeling full with indigestion and nausea usually happens when your stomach is irritated or not digesting food well. Common reasons include acidity, gas, eating heavy meals, antibiotics disturbing your gut, or mild stomach infections. Try eating light meals, drinking plenty of water, avoiding oily/spicy food, and taking simple antacids if needed. If the discomfort keeps coming back or you feel very weak, it is best to get a check-up.
