Bariatric surgery is a personal decision that only you can make. Generally, bariatric surgery is recommended for patients who have unsuccessfully tried diets, exercise and nutritional counseling — and who are committed to making lifestyle changes.
Certain health conditions, however, may qualify you as a bariatric surgery candidate.
  • Have a body mass index (BMI) of more than 40. Men and women who are more than 100 pounds overweight.
  • Have a BMI of 35-40 with an obesity-related condition such as diabetes, high blood pressure, high cholesterol, heart disease or sleep apnea.
  • Can’t achieve sustained weight loss with only diet and exercise.
  • Are committed to lifestyle changes in diet, exercise and behavior.
  • Are committed to lifelong follow-up medical care.
Dr. Alexander has successfully and safely performed many surgeries. Bariatric procedures are considered major surgery, and you must consider the risks and long-term health benefits.
