What kinds of bariatric surgery?

 Bariatric surgery, in simple terms, is engaged in the prevention, detection and treatment of the reasons expressed by the excess body weight, which is known as obesity.

 Bariatric operations belong to complicated surgical procedures, changing the anatomy and / or volume the gastrointestinal tract. Some operations of this kind are conducted under general anesthesia and requires a midline incision of the anterior abdominal wall. Other bariatric surgeons prefer laparoscopic procedures, which are held using the small tool with a camera on the end, allowing viewing from inside the abdominal cavity.

• Combined: restrictive-malabsorptive such as gastric bypass surgery

How bariatric surgery affects the digestive processes?

Before surgery

In the mouth occurs chewing food, which is then swallowed and through the esophagus enters the stomach (roughly the size of a small melon). In the stomach, the food dissolves to smaller particles by means of gastric juice. The resulting semi-solid gruel (chyme) enters the small intestine, where it undergoes further digestion by enzymes and bile. The first, the shortest part of the small intestine - is the duodenum. There occurs absorption of calcium, iron, and some vitamins. The second and third sections of the small intestine are known as the jejunum and ileum, respectively. The length of each section is about three meters. Here, the bulk of nutrients food of is sucked  causing its caloric, vitamins and minerals.

After surgery

During bariatric surgery there is a significant (90%) reduction in stomach: to the size of chicken eggs or thumb. As a rule, new stomach accommodates 3-4 tablespoons of food. Such a reduction in the size of the stomach significantly reduces the amount of food which a person can eat at one time, and accelerates processes saturation.

During bypass surgery is modified anatomy of the digestive tract behind the stomach. Leaving the a small gastric pocket, formed during banding, food "bypasses" the duodenum and into the final jejunum. As a result, in the blood enters substantially less calories and nutrients because the food passes the main part of the small intestine and less is contacting with the digestive enzymes.

Bariatric surgery requires the formation of new food habits?

Yes. All operations at digestive tract, aimed at reducing the weight, requires from patients significant changes in eating habits, and overeating a very bad effect on health. After bariatric surgery for the rest of the patient's life is exposed the risk of formation of the deficiencies nutrient.

 Whether strongly reduced weight after bariatric surgery?

 Some patients after bariatric surgery lose weight over 45 kg, and some - 90 kg. As a rule, the imposition of a gastric band is accompanied by a smaller weight loss than gastroplasty and bypass surgery, such as bypass surgery or Biliopancreatic surgery. Some patients are able to reach the normal body weight, while others retain its surplus although weigh significantly less than prior to surgery.
