Obesity and Overweight

Obesity and overweight describe having more body fat than is healthy, which raises the risk of conditions such as type 2 diabetes, high blood pressure, and heart disease. In adults, body mass index (BMI) is the common screening measure: a BMI of 25 to under 30 is classified as overweight, and 30 or higher is classified as obesity. Weight is shaped by many factors including genetics, behavior, environment, sleep, stress, and certain medications. Avita MD primary care providers diagnose and manage obesity and overweight for adults in Los Altos, Mountain View, and Los Gatos.

What are the symptoms of obesity?

Excess weight itself is the central finding, and it can bring related signs that affect daily life and long-term health.

• A body mass index (BMI) of 30 or higher
• An increasing waist size
• Shortness of breath during everyday activity
• Joint pain, especially in the knees, hips, and back
• Fatigue, low energy, or poor sleep

Adult BMI categories

Category	BMI range (kg/m²)
Underweight	Less than 18.5
Healthy weight	18.5 to less than 25
Overweight	25 to less than 30
Obesity	30 or greater

BMI is one indicator and is most useful alongside other measures such as waist size and overall health history.

How does Avita MD diagnose and treat obesity?

Care begins with a full assessment: BMI, waist measurement, health history, and on-site labs to check related markers such as blood sugar, cholesterol, and thyroid function. Your Avita MD provider reviews these results with you and builds a realistic plan. The practice’s medical weight loss program brings together personalized nutrition guidance, activity recommendations, and behavior support, with medical oversight throughout.

When lifestyle steps need added support, providers can discuss prescription options. GLP-1 medications such as semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) may be appropriate for some adults and are always paired with diet and activity changes. Longitudinal tracking lets your provider follow progress over months and adjust the plan, and same-day and next-day appointments make it easy to start or check in. Avita MD also coordinates referrals to dietitians and other specialists when a more intensive approach is helpful.

When should you see a doctor about obesity?

Talk with a primary care provider if your BMI is 25 or higher, if your waist size is increasing, or if you have tried to lose weight on your own without lasting results. It is especially important to be evaluated if you have related conditions such as high blood pressure, prediabetes or diabetes, high cholesterol, or sleep apnea, since weight management can directly improve them. Sudden or unexplained weight change, new shortness of breath, or chest pain should be checked promptly. A visit is a chance to understand your numbers and choose a safe, sustainable plan with medical guidance.
