Gastric Bypass Requirements
Gastric Bypass Requirements That Must Be Met
A gastric bypass, more commonly known as bariatric surgery, is a surgical method designed to intervene with normal digestive processes in order to deal with extreme obesity. While it is a proven method for hastening weight loss and keeping it to a desired minimum, it has associated risks and is therefore not appropriate for everyone. As such, doctors and surgeons alike follow a strict list of gastric bypass requirements and only those that meet these criteria are recommended to have bariatric surgery. Below is a quick rundown of these gastric bypass requirements including a discussion for the reason behind each so patients looking to get gastric bypass can first assess themselves whether this is indeed the way to go.
The most important criteria for determining eligibility for gastric bypass is whether or not a patient is suffering from other life-threatening conditions aggravated by obesity. There is a very strong correlation between weight and diseases like high-blood pressure, diabetes, and cardiovascular failure. Doctors need to assess the likelihood of these diseases resulting to fatal consequences before deciding on the need for gastric bypass. Compared to other reasons, this one is sufficient to stand by itself and does not need any of the other gastric bypass requirements in order to be justified.
The Consensus Panel of the National Institute of Health also requires that only morbidly obese persons are eligible for gastric bypass. Extreme obesity is defined as having a body mass index (BMI) of higher than 40. One can easily calculate his BMI by dividing weight in kilograms to the square of the height in meters. Healthy BMI ranges should not exceed 25; higher values are considered obese with above 30 values constituting morbid obesity. However, a BMI of 40 does not automatically qualify a patient for bariatric surgery.
A supplementary criteria designed to facilitate more natural methods of weight loss requires that patients must have tried and failed various programs of exercising and diet as a means to naturally losing weight. The body has the inherent tendency to easily slim down provided the calories burned per day is higher than the calories taken in. The method behind dieting and exercise is to increase the calories used through exercising and reducing the calorie intake by healthy dieting. Only if people meet these gastric bypass requirements will doctors recommend the use of gastric bypass.
In layman’s terms, a gastric bypass is done by rerouting a portion of the esophagus straight to the intestines allowing it to “bypass” the stomach. The stomach cavity is also “stapled” to reduce its total volume. As a result, calorie consumption which normally happens in the stomach is minimized. Stapling also reduces the stomach volume which means the patient feels full faster than if the stomach was allowed to stretch as before. These surgical procedures are invasive that they can cause more harm than good to those who do not actually need it.
Patients need to understand the consequences of getting gastric bypass as the condition will prove to be permanent even after one has lost the extra weight. Post-surgery, patients will need to adopt a new lifestyle such as smaller but more frequent meals to allow them to live with the bypass. The gastric bypass requirements are meant to ensure that patients put careful thought into the process before deciding if it is something they would want to deal with for the rest of their lives. However, in the majority of case those who have the surgery are pleased and have a much better lifestyle.
