Symptom guide
Hair loss on a GLP-1
Quick answer
Hair shedding can happen when your weight changes quickly and your diet runs low on protein. It's usually temporary. In midlife, changing hormones can thin hair too, so it's worth mentioning both to your doctor.
What often helps
- Hit your protein goal for the day.
- Vary your foods to get iron and zinc (meat, beans, eggs).
- Avoid very restrictive diets on your own.
When to get medical care
- Heavy shedding for more than 3 months, or bald patches on your scalp.
- Ask your doctor whether blood tests make sense for you.
In an emergency, call 911 or go to the nearest emergency room.
