Symptom guide
Fatigue on a GLP-1
Quick answer
Eating much less than before can leave you low on energy, especially when protein and water fall short. In perimenopause, sleep broken by night sweats can add to it.
What often helps
- Get some protein at every meal.
- Drink water through the day.
- Go to bed around the same time when you can.
- Light movement, like a walk, often helps your energy.
When to get medical care
- Tiredness that doesn't get better in 1 to 2 weeks.
- Fainting, a racing or pounding heart, or shortness of breath.
- If it's severe, lasts more than a few days or gets in the way of eating and drinking, talk to your doctor or care team.
In an emergency, call 911 or go to the nearest emergency room.
