GLP-1 medicines are powerful, but they are not for everyone. Deciding who they suit is a medical judgement that weighs your weight, health conditions, other medicines and personal history. This guide explains the factors a doctor considers — it does not replace that assessment.
Who a Doctor May Consider It For
Depending on the specific medicine and its approved use, a doctor may consider a GLP-1 medicine for:
- Adults with type 2 diabetes who need better blood-sugar control.
- Adults with obesity (a high body-mass index), where weight is affecting health.
- Adults who are overweight and also have a weight-related condition such as high blood pressure, high cholesterol, sleep apnoea or prediabetes.
- People for whom diet and activity alone have not achieved enough improvement.
Exact criteria (including BMI thresholds) depend on the product and current medical guidance, which is why a professional assessment matters.
Who Should Not Use It
These medicines are generally avoided in people with:
- A personal or family history of medullary thyroid cancer, or the syndrome MEN 2.
- A history of pancreatitis.
- Pregnancy, plans to conceive soon, or breastfeeding.
- Type 1 diabetes (these do not replace insulin).
- Certain severe digestive disorders, such as significant gastroparesis.
Use With Caution
Tell your doctor if you have gallbladder disease, kidney problems, a history of eating disorders, or you take other diabetes medicines (such as insulin or sulfonylureas), which can raise the risk of low blood sugar. Your doctor may still prescribe, but with extra monitoring.
Why a Doctor Must Decide
Eligibility is not a self-test. A doctor confirms the diagnosis, checks your history and other medicines, chooses the right product and dose, and monitors your progress and safety. Self-prescribing — or buying without a prescription — skips these safeguards and is unsafe.
