Mounjaro, with its active ingredient tirzepatide, belongs to a class of drugs known as GLP-1 receptor agonists. However, what sets Mounjaro apart from other medications in this category is its dual-action mechanism. Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist, meaning it mimics the action of two key gut hormones involved in metabolic regulation.
These hormones play an essential role in appetite control, insulin secretion, and glucose metabolism. By activating both the GIP and GLP-1 receptors, Mounjaro provides a synergistic effect that enhances weight loss and blood sugar control more effectively than other GLP-1 receptor agonists.
One of the primary ways Mounjaro aids weight loss is by reducing hunger and increasing the feeling of fullness. The GLP-1 hormone helps slow gastric emptying, meaning food stays in the stomach longer, leading to prolonged satiety. Additionally, the GIP component enhances this effect by improving the body’s sensitivity to insulin, reducing cravings, and promoting a lower calorie intake.
Mounjaro works to stabilise blood glucose levels by enhancing insulin production in response to food intake. At the same time, it suppresses the release of glucagon, a hormone responsible for increasing blood sugar levels. As a result, patients experience improved metabolic function, which contributes to weight loss and better overall health.
Tirzepatide helps the body utilise stored fat more efficiently by increasing insulin sensitivity and reducing insulin resistance. Since insulin plays a crucial role in fat storage, improved insulin function leads to reduced fat accumulation and greater energy expenditure. This makes it easier for patients to shed excess weight.
The brain's hypothalamus plays a critical role in regulating hunger and satiety. By mimicking natural gut hormones, Mounjaro influences brain signalling pathways to decrease hunger and reduce the urge to overeat. This is particularly beneficial for individuals struggling with emotional eating or food addiction.
Several clinical trials have demonstrated the significant weight-loss benefits of Mounjaro. The SURMOUNT trials, which evaluated the effects of tirzepatide in individuals with obesity or overweight conditions, showed impressive results:
Participants lost an average of 15-22% of their body weight over a 72-week period, depending on the dosage used.
Compared to placebo groups, those taking Mounjaro experienced substantial reductions in BMI and waist circumference.
Many patients saw improvements in weight-related conditions such as high blood pressure, cholesterol levels, and insulin resistance.
These findings highlight Mounjaro’s potential as a game-changing medication for individuals seeking sustainable weight loss.
Candidates who may benefit include:
Individuals with a BMI of 30 or higher (obese).
Those with a BMI of 27 or higher with weight-related conditions such as hypertension or type 2 diabetes.
People who have tried diet and exercise but struggle with significant, long-term weight loss.
Patients looking for an alternative to bariatric surgery.
Like any medication, Mounjaro has potential side effects. Common side effects include:
Gastrointestinal issues such as nausea, vomiting, diarrhoea, and constipation.
Decreased appetite, which can lead to lower calorie intake.
Mild hypoglycaemia (low blood sugar), particularly when used with other diabetes medications.
Injection site reactions, such as redness or irritation.
Serious but rare risks include pancreatitis, gallbladder disease, and thyroid tumours. It is essential for patients to discuss potential risks with their pharmacist before starting treatment.
