Can Ibuprofen Cause Weight Gain or Water Retention?
Ibuprofen may lead to temporary water retention and swelling, which can look like weight gain. Learn why it happens and who is at higher risk.


Can Ibuprofen Cause Weight Gain or Water Retention?
Ibuprofen is widely used for pain, inflammation, and fever relief, but some people have noticed swelling or changes in their weight while taking it. The short answer is ibuprofen can sometimes cause water retention, which may appear as temporary weight gain.
This effect happens because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can alter kidney function and fluid balance. In some people, this may lead to mild swelling in the hands, feet, or ankles. This type of “weight gain” is usually due to fluid buildup, not body fat.
For most healthy adults using ibuprofen occasionally and at the recommended dose, water retention is not a major concern. However, people with heart disease, high blood pressure, or kidney problems may be more sensitive to this side effect and should consult with a doctor before taking ibuprofen regularly.
