Gastric bypass is a kind of surgical interference that is
mostly used for significant weight loss if you are over weight. This surgical
interference reduces your calorie intake. After the surgery, stomach will be
small and you feel full faster to reduce amount of food. Part of stomach with
small intestine will be literally skipped over so less amount of calories.
Gastric bypass is also known as Roux-en-Y gastric bypass, Bariatric surgery -
gastric bypass.
In Gastric by pass stomach is made small by creating a new small pouch at the
top of abdomen by using plastic bands or surgical staples. The smaller stomach
connected directly with the middle portion of small intestine called as jejunum,
bypassing the remaining part of stomach and upper potion of small intestine
called as duodenum. After performing Gastric bypass the patient is recommended
to reduce the quantity of his intake food as small intestine absorbs less
calories at this stage. This leads to weight reduction.
Doctors will only recommend for bypass surgery if you have no other way to lose
weight and it is only considered if your body mass index 40+. Bypass surgery
usually needs 4 to 6 day hospital stay. Most people return to normal activities
within 20 to 30 days. Gastric bypass may sometime cause dumping syndrome.
Dumping syndrome occurs when food moves very quickly through stomach and
intestines, which causes sweating, weakness, faintness, nausea and sometimes
diarrhea just after eating. These symptoms may go worse by taking high calorie
foods.
As other surgeries, gastric bypass surgery also includes risks. Risks include:
- Leak from stomach into abdominal cavity that can cause
peritonitis.
- Blood clot in lung.
- Vitamin B12 deficiency- this occurs in near about 30%
cases.
- An iron deficiency anemia- this occurs in 50 cases.
- Possibility of ulcers in 10% to 20% cases.
The weight reduction results after gastric bypass surgery are
normally steady. Most patients reduce an average of 8 pounds every month and can
reach towards stable weight between 20 and 25 months. Usually, greatest rate of
weight loss take place in very beginning i.e. just after the surgery when you
are just on liquid diet.
