We have compiled the most frequently asked questions about GLP-1 to make it easy for you to find the answers you need.
GLP-1 analogues aid weight loss by mimicking the body’s natural GLP-1 hormone, which plays an important role in regulating appetite and blood sugar levels. When GLP-1 analogues are used, they affect the brain’s satiety centers, making you feel full faster and reducing appetite, which helps lower calorie intake.
Additionally, GLP-1 analogues slow gastric emptying, prolonging feelings of fullness after meals. The treatment also positively impacts blood sugar levels by stimulating insulin release as needed, which is particularly beneficial for individuals with type 2 diabetes or insulin resistance.
With GLP-1 analogues, you may begin to notice results within a few weeks, but the actual weight loss varies from person to person. Many people experience gradual weight loss after about 4–8 weeks, while others may need more time depending on the body’s response, diet and activity levels.
Greater results are typically seen after three to six months, especially when the treatment is combined with healthy eating habits and regular exercise. Our doctors will monitor your progress and adjust the dosage as needed.
The most effective GLP-1 analogues for weight loss are Semaglutide (Wegovy) and Liraglutide (Saxenda). Semaglutide is administered as a weekly injection and has been shown to produce significant weight loss, with an average reduction of approximately 15% over a year. Liraglutide is administered daily via injection and achieves an average weight loss of 5–7% over a year.
Both Semaglutide and Liraglutide help reduce appetite and increase feelings of fullness, supporting sustainable weight loss.
Weight-loss medications are typically intended for individuals with a BMI of 30 or higher, which is classified as obesity. People with a BMI between 27 and 30 who also have weight-related health issues, such as back pain, joint pain, type 2 diabetes, high blood pressure or cardiovascular disease, may also be eligible for treatment.
Since weight-loss medications are not suitable for everyone, an individual assessment is conducted by a specialist doctor who considers the person’s overall health, weight, lifestyle habits and any other medical needs.
Weight-loss medications may cause certain side effects, which vary depending on the drug and individual. Common side effects include gastrointestinal issues such as nausea, diarrhea, constipation and abdominal pain, especially at the start of treatment. Some individuals may also experience reduced appetite, dizziness, headaches or dry mouth. In some cases, mood changes or sleep problems may occur.
These side effects are often mild and tend to decrease as the body adjusts to the medication, but it is important to report any concerns to our doctor, who can adjust the dosage or explore other options.
Weight-loss medications do not necessarily need to be taken for life. They are often used as a tool to kickstart weight loss and establish new, healthier habits. The goal is usually for the medication to aid in reducing weight until sustainable lifestyle changes are achieved, where diet and physical activity can maintain long-term weight loss.
However, some individuals may require long-term medication use to maintain a healthy weight and reduce the risk of regaining weight, especially if underlying health issues are present.
Results from weight-loss medications vary depending on the individual and the drug, but many people begin to see gradual weight loss within the first few weeks. It is common to achieve a 5–10% reduction in body weight within three to six months if the medication is combined with healthy diet and exercise habits.
Some may notice results sooner, while others may require more time to see significant changes. A stable and sustainable weight loss is often slow and doctors usually follow up on the treatment to adjust dosing or set goals based on individual progress.
Regular exercise is an important part of a healthy lifestyle and can enhance the effects of weight-loss medications. Exercise helps boost metabolism, build muscle mass and burn calories, all of which support weight loss and improve overall health. Try to find activities you enjoy to create a sustainable exercise routine.
Results vary from person to person, but many people experience gradual weight loss within a few weeks to a couple of months. Combining a healthy diet, regular exercise and weight-loss medications increases your chances of success and helps you achieve and maintain a healthy weight in the long term.
