About GLP-1 & weight loss
- What they are
- Incretin analogues — GLP-1 and dual/triple agonists. They slow stomach emptying and act on appetite centres in the brain, so you eat less without white-knuckling it.
- How they're run
- One subcutaneous shot a week for most, on the same day each week. Doses climb in steps every four weeks; that slow titration is what keeps side effects tolerable.
- What to watch
- Nausea, constipation, and reflux are near-universal in the first month. Muscle is lost alongside fat unless you keep protein high and keep lifting. Tell any surgeon or anaesthetist you are on one.
