What Are GLP-1 Medications?

GLP-1 medications have transformed the treatment of obesity, type 2 diabetes, and metabolic disease. They work by helping regulate appetite, slowing stomach emptying, and improving blood sugar control.

This guide explains how GLP-1 medications work, who may benefit, possible side effects, and what to expect during treatment.

What Does GLP-1 Mean?

GLP-1 stands for Glucagon-Like Peptide-1, a hormone naturally produced in the intestines after eating.

GLP-1 helps your body by:

• Increasing feelings of fullness

• Slowing stomach emptying

• Reducing hunger

• Improving insulin release

• Lowering blood sugar

These natural effects help many people eat less without constantly feeling hungry.

How Do GLP-1 Medications Work?

GLP-1 medications mimic your body's natural GLP-1 hormone.

They help:

✓ Reduce appetite

✓ Decrease food cravings

✓ Improve blood sugar control

✓ Slow digestion

✓ Promote gradual, sustainable weight loss

Many patients notice they feel satisfied with much smaller meals.

Common GLP-1 Medications

• Semaglutide

• Tirzepatide

• Retatrutide (investigational)

Each medication has unique characteristics, but all work by improving metabolic health.

Who May Benefit?

GLP-1 therapy may be appropriate for adults who:

• Have obesity

• Are overweight with weight-related medical conditions

• Have insulin resistance

• Have prediabetes

• Need additional help after lifestyle changes alone

A medical evaluation is necessary to determine if treatment is appropriate.

Who Should NOT Take GLP-1 Medications?

GLP-1 medications are generally not recommended for individuals with:

• Personal or family history of medullary thyroid carcinoma (MTC)

• Multiple Endocrine Neoplasia syndrome type 2 (MEN2)

• Pregnancy or planning pregnancy

• Prior serious allergic reaction to a GLP-1 medication

Your healthcare provider will review your medical history before prescribing treatment.

Common Side Effects

Most side effects improve as the body adjusts.

Common side effects include:

• Nausea

• Constipation

• Diarrhea

• Heartburn

• Fatigue

• Decreased appetite

Starting with a low dose and increasing gradually can help minimize side effects.

Frequently Asked Questions
