How do you actually know if you are going to get diarrhea or constipation when you start taking a GLP-1? What decides which set of side effects you end up dealing with? Is it genetics, what you eat, or just your starting gut health?

I am currently taking 7.5mg of tirzepatide and I get severe constipation. I basically have to rely on Mag07 right now. But my friend is on the exact same dose and has the complete opposite problem, so she relies heavily on Imodium. We eat very similar foods, started at the same weight, take the same dose, and even take our shots at the exact same time. Despite all of that, our stomachs are reacting in totally different ways. Does anyone know why this happens?
