Semaglutide injections have transformed weight loss outcomes for millions of adults, with clinical trials showing average weight reductions of 10-15% over 68 weeks. However, not everyone is a candidate, and understanding your eligibility is the first step toward personalized treatment. PlexusDx evaluates your individual health profile to determine if semaglutide is right for you.

Semaglutide Eligibility Criteria for Weight Loss

Semaglutide injections are typically appropriate for adults with a BMI of 30 or higher, or those with a BMI of 27 or higher who have weight-related health conditions such as type 2 diabetes, hypertension, or sleep apnea. Your age, current medications, and medical history all factor into whether semaglutide is safe and effective for your specific situation. PlexusDx reviews these factors during your initial consultation to ensure you receive treatment that matches your health needs.

Many people assume they must have tried and failed multiple diets before qualifying, but that is not necessarily a requirement. What matters most is your commitment to lifestyle changes alongside medication—semaglutide works best when combined with consistent eating and activity habits. Your PlexusDx provider will discuss your readiness and expectations during the evaluation process.

Medical Conditions That May Affect Your Candidacy

Certain medical histories require extra caution or may disqualify you from semaglutide use. A personal or family history of medullary thyroid cancer, multiple endocrine neoplasia type 2, severe pancreatitis, or severe gallbladder disease may prevent semaglutide treatment. Additionally, if you are pregnant, breastfeeding, or planning pregnancy within the next few months, semaglutide is not recommended.

People with a history of diabetic retinopathy or those taking specific blood pressure or diabetes medications may still be candidates, but they require closer monitoring and dose adjustments. PlexusDx compiles your complete medical picture during intake to identify any potential contraindications and determine the safest approach for your weight loss goals.

Age and Medication Interactions to Consider

Adults aged 18 and older can generally access semaglutide for weight loss, though older adults may require individualized assessment due to age-related changes in metabolism and medication tolerance. Your current medications—especially those for thyroid disease, heart conditions, or diabetes—may interact with semaglutide, so a complete medication review is essential. PlexusDx providers screen for these interactions to prevent complications and optimize your treatment.

If you take medications that slow gastric emptying, such as certain diabetes drugs or pain relievers, your provider may adjust your semaglutide approach or timing. Similarly, if you are on blood thinners or have kidney disease, your dose and monitoring plan may differ from standard protocols. Transparency about all supplements, over-the-counter drugs, and prescription medications helps PlexusDx create a personalized plan tailored to your exact health profile.

How PlexusDx Determines Your Semaglutide Eligibility

PlexusDx begins with a detailed medical questionnaire and health screening to assess your weight loss history, current health status, and treatment goals. A licensed healthcare provider reviews your information and may order or request recent lab work to confirm you are a suitable candidate. This personalized evaluation ensures that semaglutide is not just appropriate for your BMI, but also safe given your unique medical context.

Once approved, PlexusDx offers compounded semaglutide injections at $189/mo month-to-month, or from $149/mo on the 6-month plan, with flexible dosing plans tailored to your response and tolerance. No insurance is required, and HSA and FSA accounts are accepted, making treatment accessible regardless of your coverage situation. Your dose may need to go up as your body adapts, but your price remains flat—no hidden costs or surprise increases based on dose adjustments.

Genetic Insights Into Your Weight Loss Potential

PlexusDx offers an optional Precision Peptide Genetic Test ($298) that identifies your unique genetic predispositions related to weight regulation and GLP-1 response. This test examines key genetic variants such as GIPR rs1800437, FTO rs9939609, and MC4R rs17782313—markers that influence how your body responds to semaglutide. Understanding these genetic factors helps your provider fine-tune your treatment for maximum effectiveness.

The Precision Peptide Genetic Test maps 14 metabolic pathways and analyzes 49 peptides across 150+ genetic insights relevant to weight management. This precision approach means your semaglutide regimen can be customized not just to your medical history, but to your genetic profile. Patients who know their genetic predispositions often achieve better weight loss outcomes and experience fewer side effects because their treatment is aligned with their biology.

How Your Genetics Relate to GLP-1 Pathways

Not everyone responds to GLP-1 medications the same way. Genetic variants — including GIPR rs1800437, FTO rs9939609, and MC4R rs17782313 — relate to the biological pathways these medications act on. These are pathway-level associations only and do not predict how much weight you will lose or how you will respond to any specific medication. PlexusDx maps 14 pathways, 49 peptides, and 150+ genetic insights so you and your provider can see how your genes relate to these pathways. It does not recommend, prescribe, or determine which medication, dose, or peptide is right for you. The PlexusDx Precision Peptide Genetic Test ($298) gives you and your provider pathway-level genetic context to support a more personalized conversation. Genetics is a guide, not a guarantee.

Frequently Asked Questions

What is the minimum BMI to qualify for semaglutide through PlexusDx?

PlexusDx typically serves patients with a BMI of 27 or higher, especially those with weight-related health conditions like diabetes or hypertension. Patients with a BMI of 30 or higher are generally eligible regardless of other conditions. Your specific qualifications depend on your complete health profile, which PlexusDx providers evaluate during your initial consultation.

Can I get semaglutide if I have type 2 diabetes?

Yes, semaglutide can be highly effective for people with type 2 diabetes, and clinical data shows it improves both blood sugar control and weight loss. However, you will need to inform PlexusDx about your diabetes medications, as some may require adjustment when starting semaglutide. Your provider will monitor your glucose levels and medication needs throughout your treatment.

Does PlexusDx require insurance approval or membership fees?

PlexusDx does not require insurance, membership fees, or prior authorization to access semaglutide injections. Treatment is $189 per month month-to-month, or from $149/mo on the 6-month plan and is available across all 50 states, with HSA and FSA eligibility. This direct-access model makes personalized weight loss therapy affordable and hassle-free for eligible patients.

What if I have had pancreatitis or thyroid cancer in the past?

A history of severe pancreatitis or personal or family history of medullary thyroid cancer typically disqualifies you from semaglutide use due to safety concerns. PlexusDx providers will identify these contraindications during your health screening and discuss alternative options if appropriate. Always disclose your complete medical history so your provider can make an informed decision.

How does the Precision Peptide Genetic Test improve my semaglutide results?

The Precision Peptide Genetic Test identifies your unique genetic variants affecting appetite, metabolism, and GLP-1 receptor sensitivity. This information allows your PlexusDx provider to personalize your semaglutide dose, timing, and complementary strategies based on your biology rather than a one-size-fits-all approach. Patients with genetic insights often achieve faster, more sustainable weight loss with fewer side effects.
