Dr. H. Geoffrey Watson, a licensed internist, has joined renowned gastroenterologist Dr. Ralph Peterson at MacArthur GI in Oakland to address obesity, provide supervised weight-loss programs including GLP-1 therapy, and screen for and treat fatty liver disease.
The Obesity Epidemic
Obesity is associated with numerous chronic health problems, including hypertension, diabetes, heart disease, sleep apnea, asthma, depression, joint disorders, fatty liver disease, and high cholesterol. Its causes include genetics, environment, stress, medication side effects, hormonal imbalances, and other factors.
Since 1999, the prevalence of obesity in the United States has risen from 30.5% to 42.4%. Childhood obesity rates are also climbing, with approximately 19.3% of children and adolescents now affected.
Measuring Obesity: Body Mass Index
Obesity is measured using a formula called the Body Mass Index (BMI). You can calculate your own BMI on most smartphones by searching “BMI calculator” and entering your height and weight. A BMI of 25 to 29.9 is classified as overweight, and a BMI of 30 or greater is classified as obese.
Populations Disproportionately Affected
Obesity affects certain populations at higher rates. Among U.S. adults, obesity prevalence is 49.9% in Black adults, 45.6% in Hispanic adults, 41.4% in White adults, and 16.1% in Asian adults.
Treatment Options
A variety of treatments are available for obesity, including dietary counseling, exercise programs, bariatric surgery, and anti-obesity medications.
Common oral medications include:
• Adipex (phentermine): A stimulant that works by suppressing appetite.
• Contrave (bupropion/naltrexone): A combination of an antidepressant and an anti-addiction medication that helps control appetite and cravings.
• Qsymia (phentermine/topiramate): A combination of a stimulant and an anti-seizure medication that reduces appetite and cravings.
GLP-1 Receptor Agonist Therapy
Glucagon-like peptide-1 (GLP-1) receptor agonists were originally approved to treat type 2 diabetes. GLP-1 is a hormone produced naturally by the body that regulates digestion, blood sugar, and appetite by communicating with GLP-1 receptor cells throughout the digestive tract. These medications reduce cravings, appetite, and food intake by influencing the hunger hormones ghrelin, which stimulates hunger, and leptin, which signals fullness.
What We Offer
Drs. Peterson and Watson provide FDA-approved tirzepatide injections, a GLP-1 receptor agonist medication indicated for weight management. Each patient receives a comprehensive history and physical examination to ensure the safety and appropriateness of the medication as part of an overall weight-loss protocol. Dr. Peterson also offers ultrasound screening for fatty liver disease.
We look forward to helping you reach your weight-loss goals and feel your best this holiday season.
