Gastric bypass surgery, also known as bariatric surgery, is usually a last-ditch option for patients living with obesity and accompanying comorbidities like diabetes. This is because the surgery, which has become well-known as a weight loss surgery, actually makes drastic changes to the digestive tract and can lead to problems like malnutrition in the future.
Surgeons usually recommend this procedure to those with a body mass index (BMI) of over 40, or those with a BMI above 35 but with other ailments such as diabetes, heart disease or high blood pressure.
The procedure has become quite popular in India as obesity has reached epidemic proportions in the country, with approximately 5% of the country’s population now affected by the ailment. The procedure involves placing a band or sleeve around the stomach or removing a portion of the patient's stomach to reduce it to a fourth of its original size. This results in weight loss, along with reducing the risk of other illnesses that are associated with obesity.
While the procedure enables the patient to experience a significant short-term weight loss, it also reduces the risk of other serious conditions by about 70% in the first two years after the surgery. However, research has shown that after five years, almost half the patients who undergo bariatric surgery end up experiencing significant weight gain.
Weight-loss surgery, therefore, isn’t enough to ensure a healthy weight for life. It is also important to maintain a healthy lifestyle after undergoing the procedure. This includes diet, as well as including physical activity in their daily schedule.
