Side Effects & Safety

GI Side Effects

The digestive cluster — nausea, constipation, diarrhea, reflux — that dominates GLP-1 tolerability and usually settles.

GLP-1 therapy's side-effect story is overwhelmingly gastrointestinal: nausea most commonly, with constipation, diarrhea, bloating, burping, and reflux filling out the table. All trace to the same source — digestion deliberately slowed — and all share the pattern of flaring at dose changes and easing with adaptation.

Each has a standard counter: fiber, fluids, and movement for constipation; smaller low-fat meals for nausea and reflux; electrolytes during diarrhea spells. Two boundaries matter: dehydration from persistent vomiting or diarrhea can stress the kidneys, and symptoms that are severe, escalating, or painful rather than annoying deserve a clinician's eyes. Programs with 7-day support exist precisely for this adjustment window.
