Bariatric Surgery | Weight Loss Surgery in Lahore |Islamabad | Karachi
Bariatric surgery/surgical procedures are used to cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often linked to hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery).
The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch.
There is no sure method, including surgery, to produce and maintain weight loss. Some patients who have bariatric surgery may have weight loss that does not meet their goals. Research also suggests that many patients regain some of the lost weight over time. The amount of weight regain may vary by extent of obesity and type of surgery. Habits such as snacking often on foods high in calories or not exercising can affect the amount of weight loss and weight regain. Problems that may occur with the surgery, like a stretched pouch or separated stitches, may also affect the amount of weight loss.
Success is possible. Patients must commit to changing habits and having medical follow-up for the rest of their lives.
What are the side effects of these surgeries?
Some side effects may include bleeding, infection, leaks from the site where the intestines are sewn together, diarrhea, and blood clots in the legs that can move to the lungs and heart.
Examples of side effects that may occur later include nutrients being poorly absorbed, especially in patients who do not take their prescribed vitamins and minerals. In some cases, if patients do not address this problem promptly, diseases may occur along with permanent damage to the nervous system. These diseases include pellagra (caused by lack of vitamin B3—niacin), beri beri (caused by lack of vitamin B1—thiamine) and kwashiorkor (caused by lack of protein).
Other late problems include strictures (narrowing of the sites where the intestine is joined) and hernias (part of an organ bulging through a weak area of muscle).
Two kinds of hernias may occur after a patient has bariatric surgery. An incisional hernia is a weakness that sticks out from the abdominal wall’s connective tissue and may cause a blockage in the bowel. An internal hernia occurs when the small bowel is displaced into pockets in the lining of the abdomen. These pockets occur when the intestines are sewn together. Internal hernias are thought to be more dangerous than incisional ones and need prompt attention to avoid serious problems.
Some patients may also require emotional support to help them through the changes in body image and personal relationships that occur after the surgery.
