Which Factors Should You Consider Prior to Surgery?
Apart from the conditions listed above, a few other important factors that can influence your decision to receive weight loss surgery.
Once you have answered the questions above, you can schedule a pre-counselling appointment with your health advisor who may then refer to you to a bariatric surgeon.
Types of Weight Loss Surgeries
Obesity surgeries range from restrictive procedures requiring a reduction in food intake to malabsorptive procedures that alter digestion or absorption of food. Certain options include a combination of both. Each type of surgery has its own risks and benefits, however you can work together with your bariatric surgeon to decide which type of procedure is best for your medical condition.
Laparoscopic Adjustable Gastric Banding (LAGB) - In LAGB surgery, a small adjustable gastric band the size of a bracelet is placed around the top opening of the stomach to restrict the size of the passage from throat to stomach. This band is made of saline filled silicon and it has a small balloon that is used to control the size of the passage and also to restrict the intake of food into your stomach.
It is also known as a LAP-BAND procedure. It induces a feeling of stomach fullness in patients and reduces the amount of food they consume. This surgical method is relatively easy as it does not require removal of the stomach or intestine and it does not alter the natural anatomy of the person. Moreover, it has very low complication rates and short recovery time.
A LAP-BAND procedure may fail due to infection, balloon leakage or band erosion and non-availability of an expert who can make band adjustments when required. Proper after surgery care and timely visits to the surgeon can prevent such failure.
Sleeve Gastrectomy - In this procedure, a major outer part (almost 80%) of the stomach is removed along with most of the fundus and the body. The stomach is then given the shape of a narrow tube to reduce its volume, limiting the amount of food that it holds. This type of surgery also reduces hunger by curbing ghrelin, a hormone responsible for increasing appetite.
Sleeve Gastrectomy reduces the volume of the stomach without affecting its normal functioning. It is usually recommended as a first stage surgical procedure for patient with BMI exceeding 55. However, such patients may still need a second stage operation for better results.
