Obesity is one of the major health issues confronting world today. It is a state of being overweight in which persons have a surplus of body fat.
Obesity surgery is a successful way of treating obesity. It helps you reduce weight by altering the way your body digests and absorbs. The surgery usually brings changes to the stomach and/or small intestine where digestion and absorption begin and end respectively. Surgery decreases the size of the stomach. More clearly, a part of the stomach is removed or closed that restricts the amount of food entering into the stomach (called food intake restriction). Besides, the length of the small intestine is also made shorter with surgery. This results in malabsorption where the amount of food that is completely digested or absorbed is limited.
Currently, there are two main types of obesity surgery, namely, restrictive and combined restrictive and malabsorptive. Each uses different operative procedures and has its own risks and side effects. There are also other surgical methods, but usually not recommended, which include intestinal bypass, jaw wiring and liposuction.
Restrictive surgery involves placing an adjustable gastric band or staples round the stomach pouch. Statistics shows that around 80% of obese patients lose some weight and 30% reach normal weight group with this surgery. The side effects are nausea, stomach discomfort, vomiting, heartburn, abdominal pain, etc.
The second type is a combination of restrictive surgery (stomach pouch) with bypass (malabsorptive surgery). In bypass, the stomach is joined to the jejunum or ileum of the small intestine, bypassing the duodenum. The major aftereffects are nausea, weakness, sweating, faintness, diarrhea, dairy intolerance, constipation, headache, hair loss and depression.
In general, obesity surgery is a treatment choice suitable for people who have failed to lose heaviness by other methods. It involves major surgical procedures that can alter a person's life in number of ways. Therefore most experts spend time to assess whether or not a patient is ready for surgery.
