GLP-1 myths and facts

Overview

GLP-1 medicines attract a lot of online noise. Here are the claims we hear most often in clinic, and what the evidence actually says.

Why it's done and who it helps

• They are not a shortcut that works without diet change.
• They do not 'ruin your metabolism'.
• They are not licensed for cosmetic use in people of healthy weight.
• They do not repair existing kidney damage.

Myth: it works while you carry on as before

The medicine reduces intake; if you replace volume with high-calorie liquids the effect largely disappears.

Myth: muscle loss is unavoidable

Lean mass loss can be substantially reduced with adequate protein and resistance training, which is why we build both into the plan.

Myth: buying online is the same thing

Unmonitored supply without kidney bloods, dose review or a named clinician is the single biggest safety problem we see.

Preparing for your appointment

Is it 'cheating'?

No — obesity is a chronic condition and medication is one legitimate treatment among several.

Are compounded versions safe?

We do not use them; supply is through a regulated UK pharmacy only.

When to contact your care team

Contact the clinic promptly if you have any of the following:

• Vomiting or diarrhoea lasting more than 24 hours, or you cannot keep fluids down
• Passing much less urine than usual, or new swelling of the legs or face
• Severe pain in the upper abdomen that spreads to your back, with or without vomiting
• A weight change of more than 2 kg in a week that is not explained by fluid
• A missed weekly weight, a missed dose, or any hospital admission

If you are seriously unwell, contact NHS 111 or your renal unit directly rather than waiting for your next review.

Your care at KidneyWeight Clinic

Every dose change, weekly weight and kidney blood test is recorded in your clinical monitoring record, reviewed by Professor Mohammed Mahdi Althaf at six-weekly intervals and formally reassessed at 26 weeks. Booking and your initial payment are handled by professoralthaf.co.uk, medication supply by Healist Pharmacy, and follow-up appointment payments by Carebit.
