GLP-1 Injections for Weight Loss: What You Need to Know Before Starting

In the evolving world of medical weight loss, GLP-1 injections have become a breakthrough option for those struggling with obesity and related metabolic conditions. Originally developed for type 2 diabetes, these medications—such as semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro, Zepbound)—are now FDA-approved for chronic weight management in qualifying patients. But how do they work, and what should you know before starting?

At Omnia Telehealth, we specialize in personalized weight loss plans that incorporate GLP-1 medications, all managed virtually by licensed providers.

What Are GLP-1 Injections?

GLP-1 (glucagon-like peptide-1) is a hormone that helps regulate appetite, insulin secretion, and blood sugar. GLP-1 receptor agonists mimic this hormone, leading to:

  • Reduced hunger and caloric intake
  • Slowed gastric emptying
  • Improved insulin sensitivity
  • Sustained weight loss

These medications are typically administered once weekly via subcutaneous injection.

Who Is a Candidate for GLP-1 Therapy?

GLP-1 weight loss treatments are generally recommended for:

  • Adults with a BMI ≥30
  • Adults with a BMI ≥27 and at least one weight-related condition (e.g., hypertension, type 2 diabetes, high cholesterol)

Through Omnia Telehealth’s virtual platform, our licensed providers assess your eligibility, monitor your progress, and tailor your treatment for optimal results.

Benefits of GLP-1 Injections for Weight Loss

GLP-1 medications offer more than just weight loss:

  • Clinically proven results: Many patients lose 10–15% of their body weight within months
  • Improved metabolic health: Better blood sugar control, reduced blood pressure, and improved cholesterol
  • Reduced risk of chronic disease: Especially for those with prediabetes, PCOS, or metabolic syndrome

A 2021 study published in The New England Journal of Medicine showed patients taking semaglutide lost an average of 14.9% of their body weight over 68 weeks.

What to Expect: Side Effects and Safety

Most patients tolerate GLP-1 medications well. However, common side effects include:

  • Nausea or vomiting
  • Constipation or diarrhea
  • Fatigue
  • Injection site reactions

Our providers at Omnia Telehealth will monitor for these and adjust your dose as needed to ensure safety and effectiveness.

Important: GLP-1s are not recommended for individuals with a history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.
