GLP-1 Medications—What You Need to Know Before You Start

GLP-1 receptor agonists—such as Ozempic, Wegovy, and Mounjaro—have rapidly become the hottest trend in weight-loss medicine. Their effectiveness is real, but so are the risks, costs, and long-term considerations that many advertisements leave out.

At BeliteWeight, we help patients understand all their options, including how GLP-1 medications compare to powerful long-term solutions like the Gastric Sleeve and Gastric Bypass. This guide will help you decide which path may be best for you.

What Are GLP-1 Medications?

GLP-1 (glucagon-like peptide-1) receptor agonists work by mimicking a natural gut hormone that helps:

• Regulate blood sugar

• Slow stomach emptying

• Suppress appetite

• Increase feelings of fullness

Popular GLP-1 medications include:

• Semaglutide: Ozempic, Wegovy

• Tirzepatide: Mounjaro, Zepbound

Originally developed for diabetes, they’re now widely prescribed for weight loss.

Who Are GLP-1s Best For?

These medications may be appropriate for:

• Individuals with BMI ≥ 30

• Individuals with BMI ≥ 27 with conditions such as diabetes, sleep apnea, or hypertension

• Patients who need medical support after years of unsuccessful dieting

They are not ideal for casual or cosmetic weight loss. Optimal results typically require long-term or even lifelong use.

Benefits of GLP-1 Medications

Significant Weight Loss

Clinical trials show GLP-1 medications can help people lose 15–20% of their body weight.

Metabolic Improvements

GLP-1s can help improve:

• A1C levels

• Blood pressure

• Triglycerides

• Insulin sensitivity

Powerful Appetite Control

By slowing digestion and changing hunger hormones, GLP-1s reduce cravings and help patients feel satisfied with smaller portions.

Risks & Side Effects: The Full Picture

While many influencers promote GLP-1s as an “easy fix,” they come with meaningful risks.

Common Side Effects

• Nausea

• Vomiting

• Constipation or diarrhea

• Bloating

• Early fullness

More Serious Potential Risks

Gastroparesis (Delayed Gastric Emptying)

A critical concern, especially with long-term use.

Symptoms include:

• Chronic nausea

• Vomiting undigested food

• Painful fullness

• Abdominal discomfort

Some patients recover after stopping the medication; others experience lasting issues.

Gallbladder Problems

Rapid weight loss increases the risk of:

• Gallstones

• Cholecystitis

Pancreatitis

Rare but serious. Requires immediate medical care if suspected.

Muscle Loss

Rapid weight loss can include muscle loss—especially if protein intake is low.

Rebound Weight Gain

A well-documented issue.
One key study found that 67% of lost weight returned within a year of stopping semaglutide.

Cost & Durability: The “Forever Factor”

This is the elephant in the room that most ads do not mention.

GLP-1s Require Ongoing Use

These medications only work while you’re on them.
If injections stop, appetite typically returns, and weight regain is common.

Monthly Costs Add Up

GLP-1 medications can cost:

• $900–$1,400 per month without insurance

• Even with insurance, coverage can be inconsistent or stop once weight plateaus

Bariatric Surgery Is a One-Time Investment

Procedures such as the:

• Gastric Sleeve

• Gastric Bypass

are one-time procedures with long-term metabolic benefits—not recurring monthly costs.

For many patients, surgery ends up being more affordable than years of medication.
