How Long Does Semaglutide Take to Work for Weight Loss?
When starting Semaglutide for weight loss, many patients wonder about the timeline for seeing results. Typically, initial weight loss can begin within the first few weeks of treatment. Most users report losing about 5-10% of their body weight within the first 12-16 weeks. However, significant weight loss often continues for up to a year, with some individuals losing 15-20% of their body weight.
Factors that influence how quickly Semaglutide works include the individual's starting weight, adherence to dietary recommendations, and lifestyle changes. It's essential to combine Semaglutide with a reduced-calorie diet and increased physical activity for optimal results.
How Semaglutide Works
Semaglutide mimics the GLP-1 hormone, which regulates appetite and insulin secretion. By enhancing feelings of fullness and reducing hunger, it helps individuals consume fewer calories. This mechanism is crucial in achieving weight loss goals.

- Weeks 5-12: Continued weight loss, with many patients reaching 5-10% weight loss.
- Months 3-6: Significant weight loss can be achieved, often exceeding 10% of body weight.
- Months 6-12: Maximum weight loss results are typically seen, with some individuals losing up to 20% of their body weight.
