Steroids
Anti-inflammatory steroid medications like prednisone are notorious for causing weight gain. Fluid retention and increased appetite are the main reasons. Some people may also see a temporary change in where their body holds fat while taking steroids – to places like the face, the belly, or the back of the neck. If you’ve taken steroids for more than a week, don’t stop them abruptly. That can lead to serious problems. Check with your doctor first.
