Obesity is a chronic, treatable medical disease — not a lack of willpower. It is defined by the CDC as a body mass index (BMI) of 30 or higher, while a BMI of 25 to 29.9 is classified as overweight. Per CDC 2024 data, 41.9% of US adults have obesity, and the rate among Hispanic adults in particular is over 45%. Carrying excess adiposity raises the risk of type 2 diabetes, hypertension, sleep apnea, fatty liver disease, joint failure, and several cancers. At Viva Medical Center in Doral, obesity is treated as the metabolic disease it is: with a real workup, a plan built around your food culture and schedule, and — when clinical criteria are met — supervised access to our GLP-1 program. Bilingual care, in-network with the major Miami-Dade carriers, same-day evaluation available.
What Counts as Obesity
Clinicians use a combination of BMI and waist-to-hip ratio to classify body weight categories. BMI is calculated as weight in kilograms divided by height in meters squared. The official categories per the National Institutes of Health (NIH) NIDDK are:
- Underweight: BMI under 18.5
- Healthy weight: BMI 18.5 to 24.9
- Overweight: BMI 25.0 to 29.9 — increased cardiometabolic risk, but not yet classified as a disease state
- Obesity class 1: BMI 30.0 to 34.9
- Obesity class 2: BMI 35.0 to 39.9
- Obesity class 3 (severe obesity, formerly 'morbid obesity'): BMI 40 or above
- Waist circumference over 35 inches (women) or 40 inches (men) indicates higher visceral fat risk independent of BMI
Why Obesity Is a Disease, Not a Choice
The American Medical Association formally recognized obesity as a disease in 2013, and the American Heart Association, the Endocrine Society, and the World Health Organization have echoed that position. Obesity involves dysregulation of appetite hormones (leptin, ghrelin, insulin), metabolic adaptation that resists weight loss, genetic predisposition, environmental exposure, and — for many patients — the long-term effects of stress, sleep deprivation, and prior medication exposure. Treating it as a moral failing has produced 40 years of failed crash dieting. Treating it medically produces durable results.
- Leptin and insulin resistance reduce satiety signals and drive overeating
- Set-point biology drops resting energy expenditure after every dieting attempt, making sustained weight loss biologically harder over time
- Polygenic risk scores explain 40–70% of BMI variance — heritability rivals that of height
- Sleep apnea, hypothyroidism, polycystic ovary syndrome, and Cushing syndrome can drive weight gain and must be ruled out
- Per CDC 2024 data, 21.5% of Hispanic adults have a diabetes diagnosis linked to obesity-related insulin resistance
Symptoms and Complications We Screen For
Obesity itself rarely causes pain or acute symptoms, but its complications do. At your first visit we screen for the most common downstream conditions so the treatment plan can address them in parallel.
- Elevated blood pressure, glucose, or lipid panel (metabolic syndrome)
- Daytime fatigue, loud snoring, or witnessed apnea suggesting obstructive sleep apnea
- Knee, hip, or low back pain from weight-bearing stress
- Heartburn or reflux worsening when supine
- Acanthosis nigricans (dark velvety skin at the neck or armpits) — a marker of insulin resistance
- Irregular periods, infertility, or hirsutism (in women) that may signal PCOS
- Mood changes, low self-esteem, or anxiety linked to weight stigma
What a Full Medical Workup Looks Like
A real obesity evaluation is not a single weigh-in. It is a structured assessment that informs the treatment plan and identifies what is reversible. Our standard workup includes:
- Detailed history — prior weight loss attempts, current diet pattern, sleep, activity, stress, medications, family history
- Vitals and body composition — height, weight, BMI, blood pressure, waist circumference, when available bioimpedance analysis
- Labs — comprehensive metabolic panel, lipid panel, HbA1c, fasting insulin, TSH and free T4, vitamin D, B12, ferritin, liver enzymes (ALT/AST)
- Cardiovascular risk — 10-year ASCVD risk score for adults 40–75
- Sleep apnea screening with STOP-BANG questionnaire; referral for in-home sleep study when indicated
- Mental health screening — PHQ-9 for depression, GAD-7 for anxiety, binge-eating screen
- Discussion of goals, barriers, and what you have already tried
How We Treat Obesity — A Stepped Plan
Treatment is built in steps based on BMI, comorbidities, and patient preference. Lifestyle work is foundational for everyone. Medication is added when criteria are met. Surgical referral is reserved for the patients where it is the right tool.
- Nutrition plan personalized to Latin and Mediterranean food cultures — not a generic 1,200-calorie sheet
- Activity plan that meets you where you are, escalating gradually toward 150 minutes per week of moderate intensity per USPSTF guidance
- Behavioral support — addressing sleep, stress, and emotional eating; warm handoff to in-network behavioral health when indicated
- GLP-1 program — supervised access to GLP-1 receptor agonist medications when BMI is 30+ (or 27+ with a weight-related complication) and lifestyle changes have not been sufficient
- Treatment of related conditions — sleep apnea, prediabetes, hypertension, fatty liver — in parallel, not after
- Bariatric surgery referral consideration for BMI 40+, or BMI 35+ with serious comorbidities (per ASMBS 2022 and AGA criteria)
- Quarterly labs and progress check-ins, with plan adjustments based on what is actually working
Sleep Apnea and Obesity — The Hidden Driver
Obesity and obstructive sleep apnea (OSA) reinforce each other. Excess soft tissue at the airway collapses during sleep; the resulting hypoxia drives cortisol and insulin resistance, which drives weight gain, which worsens the apnea. Roughly 70% of patients with severe obesity have undiagnosed OSA. Treating the apnea (typically with CPAP, an oral appliance, or — when appropriate — weight loss alone) frequently breaks the cycle and is often what finally lets sustained weight loss happen.
Mental Health and Obesity
Depression doubles the risk of becoming obese, and obesity roughly doubles the risk of depression. We screen every weight-management patient with the PHQ-9 and GAD-7 at intake. When depression, anxiety, binge-eating, or weight-related trauma is present, we treat it in parallel with weight care — internally through our in-network psychiatry team or via a warm handoff to your preferred therapist.
Insurance and Cost
Most major Miami-Dade carriers cover the obesity evaluation visit and the in-network follow-up under their primary care benefit. Labs are processed in-network. Behavioral counseling for obesity is reimbursed by Medicare and most commercial plans (USPSTF Grade B recommendation). GLP-1 medication coverage varies — Oscar Health, some Aetna, some United, and select Cigna plans cover it for adults with BMI 30+ or with comorbid type 2 diabetes; cash and self-pay options exist where coverage is denied. Our front desk verifies your plan before the first visit and discloses any out-of-pocket cost up front.

Frequently Asked Questions
What are the health risks of untreated obesity?
Untreated obesity raises the risk of type 2 diabetes, high blood pressure, cardiovascular disease, stroke, fatty liver disease, obstructive sleep apnea, joint failure, several cancers (endometrial, kidney, colon, breast, esophageal), and reduced life expectancy. Per the CDC, adults with obesity have higher all-cause mortality and lose an average of several years of life expectancy compared with healthy-weight peers. The good news: even 5–10% weight loss meaningfully improves blood pressure, blood sugar, and cardiovascular risk.
When does lifestyle alone work, and when is medical treatment needed?
Per USPSTF guidance, every adult with a BMI of 30 or higher should be offered intensive behavioral therapy — lifestyle work alone can produce meaningful weight loss for many patients. Medical treatment is appropriate when lifestyle changes alone have not been sufficient and BMI is 30+ (or 27+ with a weight-related complication like type 2 diabetes, hypertension, or sleep apnea). The decision is made together, not pushed on you.
What is the GLP-1 program at Viva Medical Center?
Our GLP-1 program provides supervised access to GLP-1 receptor agonist medications for adults who meet clinical criteria. GLP-1 receptor agonists are a class of medications originally developed for type 2 diabetes that also support weight loss by reducing appetite and slowing gastric emptying. The program includes baseline labs, ongoing monitoring, side-effect management, and a structured plan to maintain results. We do not use brand names in public materials; the medication class and individual treatment plan are discussed in your visit.
When is bariatric surgery referral appropriate?
Per ASMBS 2022 guidelines, bariatric surgery should be considered for adults with a BMI of 35 or higher (regardless of comorbidities) or with a BMI of 30 to 34.9 plus type 2 diabetes that is not well controlled. We do not perform surgery in-house, but we coordinate referral with a bariatric program when it is the right fit, and we provide pre-surgical optimization (nutrition, vitamin repletion, comorbidity control) and life-long post-surgical follow-up.
Does insurance cover obesity treatment?
Most plans cover the office visits, labs, and behavioral counseling for obesity — USPSTF gave intensive behavioral therapy a Grade B recommendation, which obligates ACA-compliant plans to cover it without cost share. Coverage for GLP-1 receptor agonist medication varies by plan and indication. Bariatric surgery is covered by most plans for patients meeting criteria. Our front desk verifies your specific benefits before the first visit.
How are sleep apnea and obesity connected?
Roughly 70% of patients with severe obesity have obstructive sleep apnea, often undiagnosed. Excess tissue at the upper airway collapses during sleep, fragmenting sleep and driving cortisol, insulin resistance, and further weight gain. We screen with the STOP-BANG questionnaire at intake and arrange in-home sleep testing when indicated. Treating the apnea is often a turning point that lets sustained weight loss happen.
I've struggled with my mental health and my weight together. Can you help?
Yes — and we expect to. Depression and obesity each roughly double the risk of the other, and binge-eating disorder is far more common in patients seeking weight care than the general population. We screen every patient with the PHQ-9, GAD-7, and a binge-eating screen at intake, and we treat the two together — through our in-network psychiatry team, a referred therapist, or both. We do not ask you to fix one before treating the other.
Is the program available in Spanish?
Yes. All intake, visits, education materials, telehealth, and discharge instructions are delivered in English or Spanish, per your preference. Our nutrition plans are built around Latin food culture, not a generic American diet sheet — Hispanic adults in Miami-Dade are not well served by 1,200-calorie templates designed for someone else's plate.
How long does it take to see results?
Most patients begin to see weight loss within 4 to 8 weeks of starting a structured plan, but the bigger marker we watch is metabolic improvement — blood pressure, fasting glucose, and triglycerides often respond before the scale does. Sustained 5–10% weight loss over 6–12 months is a clinically meaningful outcome that lowers cardiovascular risk per the AHA. Long-term success is built on consistency, not intensity, and our follow-up cadence supports that.
When should I seek care for my weight?
If your BMI is 30 or higher, or 25 or higher with high blood pressure, prediabetes, type 2 diabetes, fatty liver, sleep apnea, or joint pain — this is the right visit. If past weight-loss attempts have left you frustrated, that is also a reason to come in. Obesity care done well is not a punishment; it is a medical workup, a plan, and follow-through.
