Who Is a Good Candidate for Semaglutide? A Complete Guide

April 13, 2026

Patient reviewing candidacy requirements for semaglutide weight loss treatment at a medical consultation

If you have been struggling to lose weight despite trying diet after diet, you are not alone. For many people in Franklin, TN, Nolensville, TN, and across Middle Tennessee, traditional weight loss methods simply do not deliver the results they need. The CDC Adult Obesity Facts estimate that roughly 40% of U.S. adults meet clinical criteria for obesity, which helps explain why semaglutide has emerged as a powerful option for those who qualify, helping patients achieve significant, sustainable weight loss when other approaches have fallen short.

But semaglutide is not right for everyone. Understanding whether you are a good candidate requires looking at several factors beyond just the number on the scale. At Body Works, we believe in personalized care that considers your complete health picture, not just a single metric. Here is what the FDA guidelines, clinical research, and real-world practice say about who benefits most from semaglutide treatment.

How Does Semaglutide Work for Weight Loss?

Semaglutide belongs to a class of medications called GLP-1 receptor agonists. GLP-1 (glucagon-like peptide-1) is a hormone your body naturally produces to regulate blood sugar and appetite. Semaglutide mimics this hormone, helping you feel fuller faster and stay satisfied longer after meals. It acts on receptors in the brain that control hunger, slows gastric emptying so food stays in your stomach longer, improves insulin response, and reduces the constant mental chatter about food that many patients describe as food noise.

The clinical results are significant. In the landmark STEP 1 trial (Wilding et al., New England Journal of Medicine, 2021), half of participants taking semaglutide 2.4 mg lost 15% of their body weight over 68 weeks, and nearly one-third lost 20% or more. Participants making lifestyle changes alone lost only 2.4%. Semaglutide works best when combined with healthy eating habits and regular physical activity: the medication controls appetite, but lasting success comes from building sustainable lifestyle changes alongside treatment. If you want the full mechanism, see our primer on how GLP-1 medications work.

What BMI Qualifies You for Semaglutide?

The FDA approved semaglutide 2.4 mg for chronic weight management in adults who meet one of two criteria: a BMI of 30 or higher (classified as obesity) or a BMI of 27 to 29.9 with at least one weight-related health condition. Your Body Mass Index is calculated from your height and weight, and it serves as the primary starting point for determining candidacy.

To put this in perspective, for someone who is 5’6″ tall, a BMI of 30 equals approximately 186 pounds. A BMI of 27 for the same height equals approximately 167 pounds. A 5’10” adult weighing 195 pounds has a BMI of 28, which qualifies if they also have a weight-related condition. At Body Works, we view BMI as a helpful screening tool, not the final word on your candidacy. Some people with higher muscle mass may have an elevated BMI without excess body fat. Others may have a “normal” BMI but still struggle with metabolic health issues related to weight. That is why we conduct comprehensive evaluations that look beyond this single number.

Weight-Related Conditions That Make You Eligible

If your BMI falls between 27 and 29.9, having certain health conditions may still make you eligible for semaglutide. These conditions, known as comorbidities, are health problems that can be caused or worsened by excess weight. Common qualifying comorbidities include:

  • Type 2 diabetes: Semaglutide was originally developed to help manage blood sugar, so it offers dual benefits for patients with diabetes
  • High blood pressure: Excess weight often contributes to elevated blood pressure, which increases heart disease and stroke risk
  • High cholesterol (dyslipidemia): Abnormal cholesterol levels frequently accompany obesity
  • Heart disease: Cardiovascular conditions often improve with weight loss
  • Obstructive sleep apnea: This breathing disorder during sleep commonly resolves or improves with significant weight reduction
  • Non-alcoholic fatty liver disease (NAFLD): Fat accumulation in the liver affects many people with obesity
  • PCOS (polycystic ovary syndrome): Women with this hormonal condition often struggle with weight management

The connection between these conditions and weight creates a cycle that is difficult to break through lifestyle changes alone. Semaglutide interrupts the cycle by enabling meaningful weight loss, which often leads to improvement in the related health issues themselves.

Who Should Not Take Semaglutide?

While many people qualify for semaglutide, certain medical conditions make this medication unsafe. During your consultation at Body Works, your provider reviews your complete medical history to ensure semaglutide is appropriate for you. You should not take semaglutide if you have any of the following:

List of medical conditions that disqualify patients from safely taking semaglutide for weight loss

  • Personal or family history of medullary thyroid carcinoma (MTC): This rare thyroid cancer has been observed in animal studies with GLP-1 medications
  • Multiple Endocrine Neoplasia syndrome type 2 (MEN 2): This inherited condition causes tumors in hormone-producing glands
  • History of pancreatitis: Previous inflammation of the pancreas increases risk with this medication
  • Gallbladder disease: Semaglutide may increase the risk of gallbladder problems
  • Gastroparesis: This condition causes delayed stomach emptying, which semaglutide can worsen
  • Pregnancy or breastfeeding: Effects on unborn babies and infants are not fully understood
  • Type 1 diabetes: Semaglutide is not indicated for this condition
  • Allergies to semaglutide ingredients: Any known hypersensitivity to the medication or its components

Be sure to tell your provider about all medications and supplements you take. Semaglutide can interact with certain antibiotics, retinoids, cortisone products, and other drugs. Full disclosure helps us ensure your safety throughout treatment.

The Body Works Candidate Evaluation Process

Determining whether semaglutide is right for you requires more than checking boxes on a form. The National Institute of Diabetes and Digestive and Kidney Diseases stresses that weight management medications should be prescribed only after a comprehensive medical evaluation that rules out contraindications and identifies the patient most likely to benefit. Body Works Nurse Practitioners and Registered Nurses conduct thorough evaluations that consider your unique health situation, lifestyle, and goals. Here is what to expect during your consultation at either the Franklin or Nolensville location.

Six step semaglutide candidate evaluation process at Body Works covering history, exam, labs, and treatment plan

Step 1: Comprehensive medical history review. We discuss your weight loss journey, previous attempts, medical conditions, family history, and current medications. This conversation helps us identify any potential contraindications.

Step 2: Physical examination and vital signs. Your provider checks your blood pressure, heart rate, and other vitals, and looks for any physical signs that might affect your treatment plan.

Step 3: Body composition analysis. Beyond BMI, we assess your body composition to understand your muscle mass, body fat percentage, and metabolic health markers.

Step 4: Laboratory testing. Blood work evaluates your blood sugar, cholesterol, liver function, kidney function, and thyroid health. These results ensure semaglutide is safe for you and help track your progress.

Step 5: Discussion of goals and lifestyle. We want to understand your weight loss goals, eating habits, activity level, and any challenges you have faced. This helps us create a realistic, personalized plan.

Step 6: Personalized treatment recommendation. Based on all this information, your provider recommends whether semaglutide is appropriate or if another approach might serve you better. Our approach is judgment-free and supportive, and we have helped hundreds of Middle Tennessee residents achieve lasting weight loss.

What If You Are Not a Candidate for Semaglutide?

If the evaluation determines that semaglutide is not the right choice for you, that does not end the conversation. Body Works offers multiple pathways to help you reach your health and weight loss goals, and sometimes the right answer is a different medication or a different approach entirely.

Alternatives include tirzepatide (a dual GLP-1/GIP receptor agonist that may be appropriate if semaglutide is contraindicated), other FDA-approved appetite suppressants, nutritional counseling with personalized meal planning, IV therapy for metabolism support, and hormone optimization if testing reveals imbalances affecting your weight. Sometimes health conditions change, and a person who does not qualify today may become a candidate in the future. We maintain ongoing relationships with our patients and can re-evaluate your eligibility as your health evolves. Schedule a Free Consultation at either the Franklin or Nolensville location to start the conversation and find out which path fits your situation.

Frequently Asked Questions

The simplest answer is that you need a BMI of 30 or higher, or a BMI of 27 or higher with at least one weight-related health condition, and no contraindications like a personal or family history of medullary thyroid cancer, pancreatitis, or pregnancy. A full medical evaluation by a licensed provider is the only way to confirm candidacy. At Body Works, the initial consultation is free and includes a comprehensive assessment.
FDA criteria require a BMI of 30 or greater, or a BMI of 27 to 29.9 with at least one weight-related comorbidity such as type 2 diabetes, hypertension, high cholesterol, heart disease, obstructive sleep apnea, NAFLD, or PCOS. Your provider also reviews your medical history and current medications to confirm there are no safety concerns before prescribing.
People with a personal or family history of medullary thyroid carcinoma, Multiple Endocrine Neoplasia syndrome type 2, pancreatitis, severe gallbladder disease, gastroparesis, type 1 diabetes, or known allergies to semaglutide should not take this medication. Pregnancy and breastfeeding are also contraindications. Your provider reviews all these factors during the initial evaluation.
Under current FDA guidance, a BMI of 26 does not meet the threshold for semaglutide weight loss treatment on its own. The minimum is 27 with a weight-related health condition, or 30 without one. Your provider may discuss alternative approaches such as nutritional counseling, lifestyle coaching, or other treatments that might be more appropriate for your situation.
Semaglutide is not FDA-approved for weight loss in people who are not overweight or obese. Using it outside the approved indications is considered off-label and is not something a responsible medical provider recommends. If you are at a healthy weight but have other concerns about appetite, metabolism, or body composition, your provider can discuss alternative approaches during your consultation.
In most cases, candidacy is determined during your initial consultation. If lab work is needed, results are typically available within a few days. Once your provider confirms eligibility and reviews the results, you can begin treatment shortly after. Body Works also schedules follow-up visits to monitor your response and adjust dosing as needed during the first months of treatment.
