What the medication actually does
While Hi-Doctor does not offer TRT, several highly effective, EU-approved medications are available for weight management. These typically work by targeting hormones that regulate appetite and satiety, leading to reduced food intake and weight loss. Examples include GLP-1 agonists like semaglutide (Ozempic, Wegovy) and liraglutide (Saxenda), or dual GLP-1/GIP agonists like tirzepatide (Mounjaro).
Side effects and when to stop
All medications carry potential side effects. Common side effects for approved weight-loss drugs can include nausea, vomiting, diarrhea, or constipation, especially when starting treatment. You should always follow your doctor's instructions and stop medication if you experience severe or concerning side effects, contacting medical help immediately.
