Once obesity sets in because of over eating, suddenly one day the thought of getting back in shape becomes strong. Although a strict regimen of reducing food quantity gradually and exercising is sure to bring results, there are some instances where this doesn’t work.
For them, surgical
methods are available now.
Bariatric surgery:
Bariatric surgery promotes weight loss by changing the
digestive system's anatomy, limiting the amount of food that can be eaten and
digested. This helps a person with extreme obesity lose weight. Only after they
have tried other methods of losing weight will they be candidates for bariatric
surgery, which today is considered a "last resort" for weight loss.
It is an option for people who have a body mass index (BMI) above 40, and for
people with a body mass index between 35 and 40 who have health problems like
type 2 diabetes or heart disease.
The basic principle of bariatric surgery is to restrict food
intake and decrease the absorption of food in the stomach and intestines. It alters
or interrupts the digestion process so that food is not broken down and
absorbed in the usual way. A reduction in the amount of nutrients and calories
absorbed enables patients to lose weight and decrease their risk for
obesity-related health risks or disorders.
Surgical and post-operative risks
People who have had bariatric surgery need to adhere to a
rigorous and lifelong diet and exercise plan to prevent complications and to
avoid putting on weight after surgery. In addition, patients may develop excess
loose and folded skin that requires further surgery to remove and tighten.
As with all types of surgery, bariatric surgery is
associated with risks including internal bleeding, deep vein thrombosis,
infections, and pulmonary embolism (blood clot in the lungs). It is estimated
that the risk of dying shortly after bariatric surgery is around 1 in 200.
Types of Bariatric surgery
There are three main bariatric surgery procedures that are
widely used. These are gastric bypass, gastric banding and sleeve gastrectomy.
Gastric bypass is the most commonly used bariatric procedure
worldwide. The procedure involves re-routing the digestive system past the
stomach in order to promote satiety and suppress hunger.
The gastric band procedure involves having an inflatable
band placed around the top portion of the stomach. This creates a smaller
stomach pouch, meaning eating less will make a person feel full and satisfy
their hunger.
With a sleeve gastrectomy, around 80% of the stomach is
removed to create a smaller stomach pouch. This reduces the amount of food that
can be consumed.
Recovery time from these procedures varies from patient to
patient. But it could take months for a patient to resume their normal daily
activities following surgery, and many will have to follow a liquid diet and
introduce normal foods slowly.
Life after bariatric surgery
This surgery can lead to long-term vitamin and mineral
deficiencies, and patients must have lifelong supplementation as a result.
Studies have also suggested that bariatric surgery may increase the risk of
other health conditions.
It is generally believed that 80% of people who undergo
weight loss surgery will experience weight gain of 10-30 pounds depending upon
initial weight loss. It is further believed that 20% of those will relapse to
their former weight and possibly gain more as the disease of morbid obesity
advances. Remember, the stomach muscles are elastic. You ingest more food, it
can enlarge again.
Considering all these factors, the saying ‘Prevention is
better than cure’ is truer in this context than in any other. So, what are you
waiting for? Take a good look at the food on your plate. Do you really need to
eat that much?
