GLP-1 S tablets almost always refer to oral semaglutide, the tablet form of a GLP-1 receptor agonist. The FDA-approved version is Rybelsus (made by Novo Nordisk).
It works the same way as injectable semaglutide (like Ozempic / Wegovy), but it’s taken by mouth.
Here’s what it does in the body:
⸻
1. Suppresses Appetite
Activates GLP-1 receptors in the brain.
Effects:
•Reduced hunger
•Increased fullness
•Smaller portion sizes
•Fewer cravings
⸻
2. Slows Stomach Emptying
Food stays in the stomach longer.
Effects:
•Longer-lasting satiety
•Less post-meal blood sugar spike
⸻
3. Improves Blood Sugar Control
Stimulates insulin release when glucose is elevated and suppresses glucagon.
Effects:
•Lower fasting glucose
•Lower A1C
•Improved insulin sensitivity over time
⸻
4. Promotes Weight Loss
Weight loss occurs mainly from eating less.
Oral semaglutide typically causes:
•Moderate weight loss (dose dependent)
•Usually somewhat less than high-dose injectable versions
⸻
5. Cardiometabolic Benefits
May improve:
•Blood pressure
•Cholesterol
•Cardiovascular risk markers
Important Difference: Tablets vs Injection
Oral semaglutide:
•Must be taken on an empty stomach
•With a small amount of water
•No food or drink for at least 30 minutes afterward
•Absorption is lower and more sensitive to timing than injections
