Can antibiotics cause weight gain in adults?

I noticed some puffiness and scale changes during my treatment, so I asked my consultant at Apollo. He explained that long-term use can alter gut bacteria which affects weight, but short courses usually just cause temporary water retention. You should clarify this with your doctor.

I was researching this because I felt heavier after a recent chest infection course. Some medical studies suggest that since antibiotics destroy gut microbes, it can temporarily change how your body processes fats and sugars. Quite fascinating, actually.

When we take strong chemicals, our body's metabolism and natural flora get disrupted, leading to temporary bloating and water retention. Practicing light yoga stretches and Kapalbhati after recovering helps in bringing the digestion back to its original strength.

Oh my god, I felt the exact same way after my wisdom tooth antibiotics! I felt so bloated and heavy. I started eating homemade dahi daily to fix my gut health, and the bloated feeling went away in a week.

Yes, this definitely happens due to gut imbalance. Taking a daily probiotic supplement helped me restore my weight and digestion quickly.

Look, a 5-day course is not going to make you fat overnight. It is mostly just bloating and gas because your digestion is upset. Drink plenty of warm water and stop stressing over the scale for a few days.
