GLP-1 Drugs: Why They Don't Work For Everyone
8 Apr
Summary
- GLP-1 drugs revolutionize treatments but vary in effectiveness.
- About 10-15% of users are non-responders to the drugs.
- Genetic factors may explain individual responses to GLP-1s.

Weight loss drugs based on GLP-1 are transforming healthcare, offering new treatments for obesity and diabetes. However, their effectiveness is not universal.
While some patients experience significant weight reduction, others see little to no change. A notable portion, estimated at 10 to 15 percent in clinical trials, are classified as non-responders, failing to lose at least five percent of their body weight.
Furthermore, patient tolerance varies widely. Some individuals tolerate the medications well, while others experience severe side effects such as nausea and vomiting, leading them to discontinue treatment. Emerging research indicates that genetic makeup may play a crucial role in determining why these drugs work differently for each person.
