GLP-1 Medications 2025: Cost, Coverage, and Who Should Consider Them
If you're researching GLP-1 medications like Ozempic, Wegovy, Mounjaro, or Zepbound, you probably have two main questions: How much will this cost me? and Am I actually a good candidate?
I'm a board-certified endocrinologist practicing at Well Endocrinology in Hinsdale, Illinois. I've been prescribing GLP-1 medications since 2015, starting with exenatide and moving through every generation of these therapies. This guide covers what you actually need to know: real pricing, insurance coverage in 2025, who benefits most, and what comprehensive care looks like.
Current GLP-1 Costs and Coverage (2025)
Cost has been the biggest barrier to GLP-1 access. That's changing rapidly. Here's what you need to know:
Medicare Coverage (Effective Mid-2026)
Following the November 2025 Trump administration agreements, Medicare will cover GLP-1 medications for obesity with:
$50 monthly copay for eligible patients
$245 government cost (down from $1,000+ list prices)
Medicare Eligibility Requirements:
BMI over 27 with prediabetes OR established cardiovascular disease, OR
BMI over 30 with uncontrolled hypertension, kidney disease, or heart failure, OR
BMI over 35 (severe obesity)
Medicaid Coverage
States can opt into $245 monthly pricing for all covered uses. Coverage varies by state. Illinois Medicaid covers GLP-1s for diabetes; obesity coverage depends on state budget decisions.
Private Insurance
Coverage is highly variable:
Most plans cover for diabetes (Ozempic, Mounjaro)
Obesity coverage (Wegovy, Zepbound) is inconsistent
Many require BMI 30+ or BMI 27+ with comorbidities
Prior authorization almost always required
Some plans increased BMI thresholds to 32 or 35 in 2024-2025
Tip: If denied, appeals often succeed with documentation of metabolic dysfunction (elevated fasting glucose, insulin resistance, lipid abnormalities).
Cash Pay Options
Manufacturer Direct Programs:
Novo Nordisk: $199/month for first two doses, then $349/month
Eli Lilly LillyDirect: $299-$499/month depending on dose
TrumpRx Platform (Launching Early 2026):
Injectable GLP-1s: $350/month initially, dropping to $250 within 2 years

Who Actually Benefits From GLP-1 Medications?
After nearly a decade of prescribing these medications, I can predict who will succeed and who will struggle. This isn't about motivation. It's about physiological fit.
Take This Self-Assessment
You're likely a strong candidate if you answer YES to 3+ of these:
☐ You think about food constantly, even right after eating (this is called "food noise")
☐ Your fasting glucose is 100-125 mg/dL or A1C is 5.7-6.4% (prediabetes range)
☐ Your triglycerides are high (>150) and HDL is low (<40 men, <50 women)
☐ You've successfully lost weight before but always regain it
☐ You're in perimenopause or menopause and your weight patterns changed abruptly
☐ You have PCOS with difficulty losing weight despite reasonable effort
☐ You're on medications for blood pressure, cholesterol, or blood sugar
☐ You're willing to commit to protein intake (0.7-1.0g per pound of goal weight) and strength training
You're likely NOT a good candidate if:
☒ You have severe reflux (GERD) or gastroparesis
☒ You already struggle to eat enough or have a restrictive eating history
☒ You have personal or family history of medullary thyroid cancer or MEN2 syndrome
☒ You're pregnant, planning pregnancy, or breastfeeding
☒ You have untreated depression, anxiety, or sleep apnea (treat these first)
☒ You have chaotic schedules that make consistent medication adherence difficult
The Phenotypes I See Weekly in My Hinsdale Practice
Perimenopause/Menopause Weight Gain:
Women in their 40s-50s whose bodies changed seemingly overnight. Weight concentrates around the midsection. Hunger patterns shift. Previous strategies stop working. GLP-1s often work exceptionally well in this population because they address the hormonal appetite dysregulation. (Read more: Understanding Midlife Weight Gain)
Insulin Resistance with High Appetite Drive:
Fasting glucose 100-110, A1C 5.7-6.4%, high triglycerides, constant hunger even after full meals. This is classic metabolic syndrome. GLP-1s improve both the glucose metabolism AND the appetite signaling.
PCOS with Hyperinsulinemia:
Difficulty losing weight, irregular cycles, elevated fasting insulin. GLP-1s address the underlying insulin resistance that drives both the metabolic and reproductive symptoms.
Cardiovascular Risk Profile:
Even without significant obesity, patients with established heart disease, prior stroke, or multiple cardiac risk factors benefit from the cardiovascular protective effects beyond weight loss alone.
What GLP-1 Medications Actually Do
GLP-1 receptor agonists (glucagon-like peptide-1) work through several mechanisms:
Quiet "Food Noise"
Food noise is the persistent mental chatter about eating that runs in the background of your day. Planning the next meal while eating the current one. Thinking about snacks constantly. Mental negotiations about whether you "should" eat something.
This isn't a character flaw. It's a hormonal signal driven by insulin resistance, leptin dysfunction, and disrupted satiety pathways. For patients with significant food noise, GLP-1 therapy often provides more relief than any amount of willpower ever did.
Patients describe it as: "I can finally hear myself think" or "Food used to control me. Now I control food."
Normalize Satiety Signaling
Many patients with insulin resistance have disrupted hunger hormones (leptin, ghrelin, PYY). Your brain doesn't register fullness reliably. You eat past satisfaction without realizing it. GLP-1s restore the signal that says "I've had enough."
Slow Gastric Emptying
Food stays in your stomach longer, which:
Extends the feeling of fullness after meals
Reduces blood sugar spikes
Decreases the urge to snack between meals
Improve Glucose Metabolism
GLP-1s help your pancreas release insulin more effectively in response to meals (glucose-dependent insulin secretion). This improves blood sugar control without causing dangerous low blood sugar.
Have Cardiovascular Benefits Beyond Weight Loss
The SELECT trial showed semaglutide (Wegovy/Ozempic) reduced major cardiovascular events by 20% in patients with established heart disease, independent of how much weight they lost. These medications affect:
Inflammation markers
Endothelial function (blood vessel health)
Atherosclerotic plaque stability
Blood pressure
Evidence Base
STEP trials: 15-17% average weight loss with semaglutide
SURMOUNT trials: 15-21% average weight loss with tirzepatide
SELECT trial: 20% reduction in cardiovascular events

How I Monitor Patients at Well Endocrinology
GLP-1 prescribing without proper monitoring leads to problems: muscle loss, nutritional deficiency, inadequate results, preventable side effects. Monitoring is central to safe, effective care.
Baseline Evaluation
Comprehensive metabolic panel
Fasting glucose, insulin, A1C
Lipid panel (LDL, HDL, triglycerides), advanced lipid markers if indicated.
Kidney and liver function
Thyroid markers if indicated
Body composition analysis (fat mass vs. lean mass)
Follow-Up Every 6-8 Weeks During Active Weight Loss
Repeat metabolic labs
Body composition reassessment
Medication adjustments for blood pressure, diabetes meds as needed
Side effect assessment and management
Nutritional adequacy check
Adherence to protein targets and strength training
What I'm Watching For
Body composition changes: If you're losing more than 20% of your weight from muscle, we adjust immediately. The goal is fat loss with muscle preservation. Weight alone doesn't tell us if you're losing the right tissue.
Metabolic improvements: Fasting glucose should drop. Triglycerides should improve. Blood pressure should stabilize. These changes confirm the medication is working at a metabolic level, not just suppressing appetite.
Nutritional adequacy: Are you eating enough protein? Do you have energy? Are you hydrated? Many patients need explicit targets: 100-150g protein daily, 80+ oz water, sometimes electrolyte supplementation during the first few months.
Side effect patterns: Nausea, reflux, constipation. Most are manageable with dose adjustments or supportive care. Some require switching medications or pausing treatment.
This level of oversight is why comprehensive endocrinology care differs from quick prescriptions through telehealth platforms. Our direct care approach to obesity treatment prioritizes long-term metabolic health over quick fixes.
The Three Habits That Make GLP-1 Therapy Work Long-Term
Medication creates metabolic space. These habits determine whether that space becomes lasting change or temporary weight loss.
1. Protein Intake: 0.7-1.0g Per Pound of Goal Body Weight Daily
If your goal weight is 150 pounds, that's 105-150 grams of protein daily. This preserves muscle mass during weight loss.
Practical sources:
6 oz chicken breast: 50g
1 cup Greek yogurt: 20g
2 eggs: 12g
1 scoop whey protein: 25g
When appetite is suppressed, protein needs to be the priority at every meal. Eat protein first, then other foods. For more on building a sustainable eating approach, see What Fits You Best in a Diet.
2. Strength Training: Minimum Twice Weekly
Not walking. Not yoga. Actual resistance training with progressive overload.
Minimum effective dose: Two 30-45 minute sessions per week hitting all major muscle groups. Lift weights that feel challenging in the 8-12 rep range.
This is the single most effective intervention to protect lean mass during weight loss. Patients who don't strength train lose significantly more muscle.
3. Body Composition Tracking
We use inbody scan to see what you're actually losing. Weight alone is misleading. We need to know: Is this fat loss or muscle loss?
Target: 75-80% of weight loss from fat, maximum 20% from muscle.
If you're losing more muscle than that, we adjust protein, training intensity, or medication dose immediately.
What Long-Term Success Actually Looks Like
After following patients on GLP-1 therapy for years, sustainable success looks different than dramatic transformations.
Patients who maintain results long-term describe:
✓ Significantly less food noise. Food no longer dominates their thoughts.
✓ Consistent meal structure without feeling compelled to finish everything.
✓ Better metabolic labs: fasting glucose drops, A1C normalizes, triglycerides improve, blood pressure stabilizes.
✓ Stable weight rather than constant fluctuation.
✓ Feeling in control of food choices, not controlled by medication.
Maintenance often involves lower doses. Many patients reduce to half their peak dose once they reach stable weight. Some space injections further apart. Very few people stay at maximum doses indefinitely. The goal is sustainable metabolic health, not maximum appetite suppression.
Common Questions About GLP-1 Medications
How long do I need to stay on GLP-1 medications?
Most patients need long-term or indefinite treatment. The WHO's December 2025 guidelines define long-term use as continuous treatment for six months or more, often years. When patients stop, weight typically returns unless metabolic patterns have fundamentally changed.
Some patients successfully maintain with lower doses, spacing injections, or transitioning off medication after 2-3 years if they've built sustainable habits and addressed underlying metabolic dysfunction.
What are the side effects of GLP-1 medications?
Most common (especially in first 4-8 weeks):
Nausea
Early fullness/satiety
Constipation
Mild reflux or burping
Less common but important:
Severe nausea preventing adequate eating or drinking
Gallbladder issues (rapid weight loss increases gallstone risk)
Pancreatitis (rare, more common with high triglycerides or gallstone history)
Dehydration
The side effect no one mentions: Undereating. When appetite drops dramatically, many patients eat too little, triggering muscle breakdown, fatigue, hair loss, and metabolic slowdown. We monitor for this explicitly.
What about Ozempic vs Wegovy vs Mounjaro vs Zepbound?
Ozempic and Wegovy: Both contain semaglutide. Ozempic is FDA-approved for diabetes. Wegovy is approved for obesity. Same medication, different indication and dosing.
Mounjaro and Zepbound: Both contain tirzepatide, a dual GIP/GLP-1 agonist. Mounjaro is approved for diabetes. Zepbound is approved for obesity.
Which is better? The SURMOUNT trials showed tirzepatide produced slightly higher weight loss (15-21%) compared to semaglutide (15-17%) in head-to-head comparisons. But individual response varies. Some patients tolerate one better than the other.
Insurance often determines which you can access. Diabetes diagnoses usually get Ozempic or Mounjaro covered. Obesity-only indications face more insurance barriers.
What's coming next in GLP-1 medications?
Retatrutide: A triple agonist (GLP-1/GIP/glucagon) currently in phase 3 trials. Phase 2 data showed 24.2% average weight loss at 48 weeks. Eli Lilly expects late-stage data in 2025.
Oral GLP-1s: Orforglipron (Eli Lilly's oral medication) showed 7.8-12.4% weight loss in phase 3 trials. Less dramatic than injectables but addresses adherence barriers. Expected FDA decision in early 2026.
Gene therapy approaches: Early research exploring ways to turn the body into its own GLP-1 factory. Years away from clinical use but represents where the field is heading.
Does insurance cover GLP-1 medications in Illinois?
It depends on your plan and diagnosis:
Most Illinois insurance plans cover GLP-1s for diabetes (Ozempic, Mounjaro.) Coverage for obesity (Wegovy, Zepbound) varies significantly
Blue Cross Blue Shield of Illinois: Variable by plan, often requires BMI 30+ and prior weight loss attempts
UnitedHealthcare: Many plans exclude obesity medications entirely
Aetna: Some plans cover with prior authorization
Illinois Medicaid: Covers for diabetes, limited obesity coverage
We help with prior authorizations and appeals. Documentation of metabolic dysfunction (insulin resistance, prediabetes, lipid abnormalities) improves approval odds significantly.
