What Is GLP-1?

GLP-1 is an FDA-approved anti-obesity medication — a synthetic version of a naturally occurring hormone (glucagon-like peptide-1) produced in the digestive tract. It works alongside a reduced-calorie diet and increased physical activity to support meaningful, lasting weight loss. Clinical studies have shown patients losing an average of nearly 15% of their initial body weight.

How Does GLP-1 Work?

GLP-1 works by slowing digestion, decreasing appetite, and helping you feel fuller faster and longer after a small meal. It comes in an injectable form administered once weekly — just under the skin in areas like the abdomen, upper arm, or thigh. The recommended program duration is 2–3 months, though treatment length is tailored to your individual goals.

What Are the Possible Side Effects?

Some of the most commonly reported side effects include nausea, constipation, indigestion, vomiting, diarrhea, abdominal discomfort, heartburn, bloating, gas, headache, fatigue, and mild jitteriness. Nausea is most common when starting treatment and typically resolves as your body adjusts. Administering GLP-1 before bed and staying well hydrated can help minimize this.
