Understanding Wegovy and Its Mechanism

Wegovy (semaglutide) is a medication approved by the FDA in June 2021 for weight loss. It functions by mimicking glucagon-like peptide-1 (GLP-1), targeting brain areas involved in appetite regulation. This helps reduce hunger, increase fullness, and slow food movement from the stomach to the small intestine, ultimately decreasing calorie consumption.

Timeline for Weight Loss Results

Initial Weeks

During the first few weeks, patients typically experience:

  • Reduced appetite
  • Earlier satiety during meals
  • Decreased cravings for high-calorie foods
  • Potential mild side effects as the body adjusts

First Month

Most people begin noticing changes within 4 weeks, with clinical trials showing an average weight loss of 1-2% of body weight. The dosage is gradually increased over 16-20 weeks to minimize side effects.

Months 2-3

Weight loss typically accelerates as patients:

  1. Adjust to the medication
  2. Develop better eating habits
  3. Experience consistent appetite suppression

Months 4-6

By the six-month mark, patients often achieve:

  • 10-15% total body weight loss
  • Improved metabolic markers
  • Better glucose control

Long-term Results

According to studies published in the New England Journal of Medicine, participants lost an average of 15-18% of their initial body weight over 68 weeks when combined with lifestyle modifications.
