Getting colds or getting sick more often on a GLP-1?
Adult labels do not list colds or a weaker immune system. Eating far less, short sleep and the season are likelier causes. Protein, sleep and fluids help.
-

Cravings on a GLP-1: sugar, salt and alcohol cravings explained
GLP-1s usually turn cravings down. Sugar cravings often mean too little food, salt can mean lost fluid, and alcohol usually loses its pull.

Why did compounded semaglutide stop working?
Often a normal plateau, but with compounded semaglutide check the dose first: a new concentration, units vs mg, an old or warm vial, a different product.

Can I take Linzess or prescription constipation meds with a GLP-1?
Often yes, if your prescriber chooses it. No label lists an interaction; the real risk is stacking diarrhea and dehydration, so start low and watch fluids.

Why don’t I want alcohol anymore on a GLP-1?
GLP-1s act on the brain’s reward system, so the pull of a drink often fades. A 2025 trial found less craving. It is common and usually a welcome change.

How long does hair loss last on a GLP-1, and does it grow back?
GLP-1 shedding usually eases within about six months and hair grows back. New hair grows about half an inch a month; fullness returns in six to nine.

Should I take B12 on a GLP-1?
Not everyone needs it. B12 makes sense if you eat little meat, fish, eggs or dairy, are over 50, or take metformin or acid reducers. Ask for a blood test.
