Who Is a Candidate for GLP-1 Therapy?
Last reviewed: May 2026 · Haute MD Editorial Team
GLP-1 receptor agonists are FDA-approved for adults with type 2 diabetes, chronic weight management in those with a BMI of 30 or higher (or 27 or higher with a weight-related condition such as hypertension, dyslipidemia, prediabetes, sleep apnea, or fatty liver), cardiovascular risk reduction in certain populations, and — for tirzepatide — moderate-to-severe obstructive sleep apnea in adults with obesity. Eligibility is increasingly evaluated on overall metabolic risk, not weight alone.
Clinical eligibility criteria
Standard FDA indications for weight management: BMI ≥30, or BMI ≥27 with at least one weight-related condition (type 2 diabetes, hypertension, dyslipidemia, cardiovascular disease, prediabetes, obstructive sleep apnea, MASLD/fatty liver, osteoarthritis, or PCOS). For type 2 diabetes, indication is broader and includes most adults with HbA1c above goal. Wegovy is now approved for cardiovascular risk reduction in adults with overweight/obesity and established cardiovascular disease. Zepbound is approved for moderate-to-severe OSA in adults with obesity.
Who should not take GLP-1 medications
Contraindications include personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN2), prior severe hypersensitivity to the drug, and active pancreatitis. Caution is warranted in patients with a history of pancreatitis, severe gastroparesis, gallbladder disease, diabetic retinopathy (semaglutide), pregnancy, or breastfeeding. Patients with active eating disorders or severe gastroparesis are typically poor candidates.
What a good candidate looks like in practice
An ideal candidate has documented obesity or overweight with comorbidity, has tried lifestyle modification, is committed to a long-term approach (these are chronic disease medications), has appropriate insurance or financial planning for cost, and is willing to combine the medication with protein-forward nutrition, resistance training, and follow-up labs. Physicians should screen for thyroid history, gallbladder disease, eating disorders, and pregnancy plans before prescribing.
Frequently Asked Questions
Can I get GLP-1 therapy if I'm only 15 pounds overweight?
Not under FDA-approved indications unless you have a weight-related comorbidity and a BMI of at least 27. Some longevity practices use lower-dose protocols off-label for metabolic optimization in lower-BMI patients, but this is not on-label.
Do I need to fail diet and exercise first?
Many insurance plans require documented attempts at lifestyle modification before covering GLP-1 therapy. Clinically, lifestyle modification is always recommended in parallel with — not as a prerequisite to — medical therapy for established obesity.
Are GLP-1 medications safe for older adults?
Yes, with appropriate monitoring. Older adults benefit from cardiovascular and glycemic improvements but are at higher risk for sarcopenia, so preserving muscle mass through protein and resistance training is especially important.
Can teens take GLP-1 medications?
Wegovy is FDA-approved for adolescents 12 and older with obesity. Saxenda (liraglutide) is also approved for adolescents 12+. Both should be used under specialist supervision.

How Do GLP-1 Medications Work?
GLP-1 medications mimic a gut hormone that suppresses appetite, slows gastric emptying, and improves insulin response — leading to lower blood sugar and significant weight loss.

What Are the Side Effects of GLP-1 Medications?
The most common GLP-1 side effects are nausea, vomiting, diarrhea, and constipation. Less common but serious risks include pancreatitis, gallbladder disease, muscle loss, and thyroid warnings.

What Is Obesity? Medical Definition and Treatment
Obesity is a chronic disease defined by excess body fat that impairs health, typically a BMI of 30 or higher. Modern treatment combines medical, behavioral, pharmacologic, and surgical options.
