Understanding Semaglutide Side Effects
Semaglutide works by activating GLP-1 receptors, which affect appetite, digestion, and insulin response. Because of this mechanism, gastrointestinal side effects are the most commonly reported.
Most side effects are temporary and tend to improve as the body adapts to treatment and dosage is gradually increased.
Most common side effects:
- Nausea
- Vomiting
- Diarrhea
- Constipation
- Loss of appetite
- Fatigue
Frequently Asked Questions About Side Effects
Nausea is the most commonly reported side effect, especially during the early stages of treatment or dose increases.
Nausea usually improves within a few days to weeks as the body adjusts to the medication and dosage stabilizes.
Vomiting can occur in some users, especially at higher doses or during early treatment, but it is usually temporary.
Semaglutide slows gastric emptying and affects gut motility, which can lead to either diarrhea or constipation depending on individual response.
Hypoglycemia is uncommon when used alone, but the risk increases if combined with insulin or other glucose-lowering medications.
Allergic reactions are rare. However, symptoms such as rash, swelling, or difficulty breathing require immediate medical attention.
Side effects can often be reduced by starting at a low dose, eating smaller meals, avoiding high-fat foods, and staying hydrated.
