Who Is Eligible for GLP-1 Therapy

GLP-1 therapy is not for everyone who wants to lose weight. It is a prescription medicine, so eligibility is decided by a doctor after an assessment, not by the number on the scale.

What is assessed before therapy is considered

The assessment starts with BMI and waist circumference. For Asian populations the BMI cut-offs used are lower than Western ones, because metabolic risk appears at a lower body weight. The doctor also looks for weight-related conditions already present: prediabetes, type 2 diabetes, high blood pressure, abnormal lipids, fatty liver, sleep apnoea or PCOS. The thresholds themselves are set in Malaysian clinical guidelines, and the assessing doctor will explain where your numbers sit.

Who is not eligible

Some situations make this therapy unsuitable or rule it out entirely.

• Pregnant, trying to conceive, or breastfeeding
• Personal or family history of medullary thyroid carcinoma, or MEN2 syndrome
• History of pancreatitis
• Severe delayed stomach emptying
• Known allergy to the active ingredient
• Type 1 diabetes, since this is not the indication

A history of disordered eating also needs assessment first, because a medicine that suppresses appetite can mask a problem that should be treated differently.

If you take other medicines

The two combinations that need the most attention are insulin and sulfonylureas. Both can push blood sugar too low when combined, so existing diabetes doses are usually adjusted at the same time. Other oral medicines can be affected because the stomach empties more slowly, and that is reviewed one by one.

When the answer is not GLP-1

Some people arrive with weight that will not move, but the real cause sits somewhere else. An underactive thyroid, high cortisol, chronic short sleep, or a medicine that drives weight gain can all look identical from the outside. That is why the assessment starts with bloods rather than a prescription. See the metabolic assessment and hormone profile for what gets checked. Read GLP-1 safety and GLP-1 side effects as well. Book a consultation for an assessment. Medicine registration status can be checked through NPRA.

Eligible is not the same as recommended

Someone can meet the criteria and still be better off starting without medicine, for instance when sleep, protein and training have never been addressed properly. GLP-1 therapy manages appetite. It does not manage muscle, sleep or stress. Leave those out and part of the weight lost comes from muscle, and it returns once the therapy stops.
