Stop Weight Loss Injections? Beware of Weight Gain
9 Apr
Summary
- Weight loss injections mimic a hormone to increase feelings of fullness.
- These NHS-prescribed jabs are for overweight individuals with health risks.
- Users may experience weight gain after discontinuing medication.

Highly effective weight loss injections are available via NHS prescription, administered weekly through pre-filled pens for self-injection. These medications function by mimicking a hormone called GLP-1, which promotes a feeling of fullness and suppresses appetite. Some drugs, like Mounjaro, also influence metabolism and energy balance.
While these jabs can be effective, their suitability may vary among individuals, with genetics potentially playing a role in their efficacy. The treatment typically begins with a low dose, gradually increased to a maintenance level.
The NHS recommends these injections for those who are overweight and have obesity-related health risks, not for cosmetic slimming. Crucially, the jabs are always prescribed in conjunction with programs focused on healthier eating and increased exercise. A key concern highlighted by experts is the risk of weight gain that may occur once patients discontinue the medication.
