What should I do if I experience fatigue or dizziness on GLP-1 medications?

Fatigue and dizziness are relatively common side effects of GLP-1 medications, often related to reduced calorie intake, dehydration, electrolyte imbalances, or blood pressure changes. These symptoms are particularly common during the first few weeks of treatment or after dose increases. They can also result from rapid weight loss or inadequate protein intake.

To manage fatigue and dizziness, prioritize hydration with 8-10 glasses of water daily, ensure adequate electrolyte intake (especially sodium, potassium, and magnesium), and eat regular meals with sufficient protein. Rise slowly from sitting or lying positions to prevent orthostatic dizziness. If symptoms persist, check your blood pressure and blood sugar with your healthcare provider. In some cases, adjusting the medication dose or timing may help. If fatigue is severe or accompanied by other concerning symptoms, seek medical evaluation to rule out other causes.
