Most Common GLP-1 Side Effects

GI symptoms are the most frequently reported class of GLP-1 side effects. They are most common when starting treatment or increasing dose, and typically improve over time.

  • Nausea — most common early side effect, often improves within weeks. Eating smaller meals and avoiding high-fat foods may help.
  • Vomiting — less common than nausea but possible, especially early. Staying hydrated is important.
  • Diarrhea or constipation — GI changes are common during early GLP-1 use. Usually improve over time.
  • Decreased appetite — an intended effect. Eating regular, small, protein-rich meals prevents undereating.
  • Fatigue — some patients report low energy early in treatment. Hydration and adequate protein may help.
  • Injection site reactions — redness or minor irritation possible with injectable GLP-1 medications.
  • Headache — often related to reduced caloric intake or dehydration.

When to Contact Your Provider Immediately

  • Severe or persistent abdominal pain, especially if it radiates to the back
  • Rapid heart rate or heart palpitations
  • Signs of a severe allergic reaction (rash, swelling, difficulty breathing)
  • Severe nausea, vomiting, or diarrhea leading to dehydration
