Advantages & Disadvantages

Gastric bypass surgery is the most common weight loss surgery in the United States. Weight loss surgeries are also known as bariatric surgeries. These surgeries are performed when diet plans, exercise and other weight loss methods do not help the patient reduce weight.

Gastric bypass surgery is performed on people who have a body mass index (BMI) of 40 and above. People, with a BMI ranging between 35 and 39.9 are also legible for the surgery. However, they are allowed to go through the procedure only if they suffer from health problems that are related to weight loss.
These problems can include type 2 diabetes, high blood pressure, severe sleep apnea, stroke and gastro esophageal reflux disease among many other issues.

Since the surgery is expensive, our surgeon tries his best to screen patients and make sure that they are eligible for surgery. The patient will also have to make permanent changes in lifestyle. The patient also needs to monitor nutritional intake, life style, medical conditions and behavior over the long-term. Regular follow-ups are necessary to help the patient to stay on track. As with other life changing surgeries, there are many pros and cons related to the surgery and the after affects of the surgery.


  • Almost 70% patients no longer require high blood pressure medicine after around two years of operation.
  • Almost 80% report normal cholesterol levels two to three months after the surgery.
  • There is a reduced risk of heart disease in patients.
  • People who have dyslipidemia- abnormal concentration of lipids in the blood- benefit from the surgery.
  • Type 2 diabetes patients do not require medication after some time of the surgery.
  • Asthma attacks reduce and in some cases, are completely gone after the operation.
  • Relief from acid reflux diseases and sleep apnea.
  • People who have respiratory problems related to weight, have reported that they have been able to breathe much better and are able to enjoy life.


Since the surgery involves a slightly complex process, it is best to see all the long term and short term problems that are related to it:

  • Infections
  • Undesirable reaction to anesthesia
  • Bowel obstruction
  • Nausea
  • Nutritional deficiency
  • Obstruction to the stomach outlet. You can no longer rely on stomach fluids to digest your food.
  • Chew your food properly before swallowing or it will block the passage.
  • Intolerance to food like milk, sugar and red meat develops.
