Can I drink coffee on a GLP-1?

Coffee is on no GLP-1 interaction list. What changed is the stomach it lands in: slower, emptier and more reactive than before.

About 2.7 L of water a day for women and 3.7 L for men, and on a GLP-1 less arrives in food, so drink a little more, with some salt.

Appetite usually changes within weeks on a GLP-1, but weight follows the dose schedule. The first month is a starting dose.

Bloating on a GLP-1 is usually a slow stomach that stays full, longer fermentation, swallowed air or held stool. It eases as you adapt.

With GLP-1 diarrhea: small, low-fat, low-sugar plates, protein first, soluble fiber to firm the stool and salted fluids to replace losses.

Constipation followed by diarrhea on a GLP-1 is usually overflow: liquid slipping around hard stool a slowed colon could not move.

Sulfur burps with a day of loose stool is a slowed gut doing two things at once. With repeated vomiting, pain or fever, call the same day.

Sulfur burps on a GLP-1 are hydrogen sulfide: gut bacteria breaking down protein that sits longer in a stomach the medication slowed.

GLP-1 diarrhea comes from the same slowdown that causes constipation, which is why the two so often take turns in the same week.
