Who qualifies for weight loss medication
When considering weight loss medication, doctors look at several factors to ensure it's safe and effective for you. Generally, these medications are for adults with a Body Mass Index (BMI) of 30 or higher, or a BMI of 27 or higher with at least one weight-related comorbidity such as type 2 diabetes or high blood pressure. Your doctor will assess your full medical history, including any existing conditions and all medications you currently take, to check for contraindications. For example, some GLP-1 medications are not suitable for individuals with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
What weight loss medication actually does (and doesn't do)
Weight loss medications, particularly GLP-1 receptor agonists like semaglutide or tirzepatide, work by mimicking natural hormones that regulate appetite and blood sugar. They slow gastric emptying, which helps you feel fuller for longer, and reduce food cravings. This leads to a reduction in calorie intake and, over time, weight loss. These medications are not a magic bullet; they are most effective when used as part of a comprehensive weight management plan that includes a reduced-calorie diet and increased physical activity. They do not replace healthy lifestyle changes but rather support them by addressing biological factors that make weight loss challenging.
Side effects and when to stop
Common side effects of weight loss medications often include gastrointestinal issues such as nausea, vomiting, diarrhoea, or constipation. These usually improve as your body adjusts to the medication. More serious, but rare, side effects can include pancreatitis or gallbladder problems. It's crucial to report any persistent or severe side effects to your doctor immediately. You should stop the medication if directed by your doctor, or if you experience severe abdominal pain, yellowing of the skin or eyes, or signs of an allergic reaction. Your Hi-Doctor will provide clear guidance on monitoring and managing side effects.
