GLP-1 Side Effects & How People Manage Them
The side effects our members search for and discuss most, with the management tips people commonly share. None of this is medical advice.
Nausea
The most commonly reported GLP-1 side effect, especially in the first weeks and after each dose increase, because these drugs slow stomach emptying.
Commonly discussed tips: Members commonly describe eating smaller, lower-fat meals, stopping before feeling full, staying hydrated, and avoiding greasy or very rich foods. Symptoms often ease as the body adjusts.

Sulfur burps
Burps with a sulfur or 'rotten egg' smell are a frequently discussed quirk of slowed digestion on these medications.

Fatigue

Commonly discussed tips: Commonly discussed approaches include losing weight at a steadier pace, prioritizing protein and strength training to preserve lean mass, and consulting a professional about skincare or cosmetic options.
