Gastric Bypass is a type of weight loss surgery; performed laparoscopically,
where by a small pouch is formed from the stomach, and the remaining stomach
and portion of the small bowel are bypassed. After the surgery, the patient
is then restricted and eats smaller portions, increasing the absence of
hunger and reducing absorption. Although, patients can anticipate reducing
their excess body weight by 80-85% over 18 months, patients must commit
to making permanent changes to lead a healthier lifestyle. Most importantly,
medical conditions are dramatically improved after the weight-loss, such
as diabetes, hypertension, hyperlipidemia, and sleep apnea.
Possible Candidates
Patients need to meet certain medical guidelines to qualify for gastric
bypass surgery. Candidates will have to go through an extensive screening
process to make sure that it’s the right choice for them. In general,
ideal candidates for the procedure have a body mass index (BMI) of 40
or higher (morbid-obesity), suffer from weight-related health conditions,
have had a hard time losing weight despite numerous efforts at diet and
exercise. Patients considering gastric bypass should be open to following
precautionary measures leading into the surgery, including avoiding alcohol
and tobacco products and stopping the use of certain medications.
Risks
Gastric Bypass surgery, as with any major surgery may have associated health
risks. There is a 1% risk of ulcer formation in the pouch, especially
if the patient takes nonsteroidal anti-inflammatory drugs (NSAIDs) or
smokes. The risk of iron deficiency in menstruating women is possible.
Other deficiencies such as Vitamin B1, B12, Folate, Calcium and Vitamin
D may occur if patients don’t continue taking their essential and
recommended supplements. Other possible deficiencies that may occur after
the surgery are hair loss during the first 3-6 months, however, this usually
resolves by the first year.
Gastric Bypass surgery is an ultimate decision that requires a lifelong
commitment from the patient. After surgery, patients may experience positive
psychological effects resulting from improved physical and mental health.
The surgery itself can produce significant improvements in quality of
life measures, such as sleep cycle, level of confidence, and how a person
views themselves, to name a few. The AVMC bariatric team will guide patients
through the process, and support their weight-loss journey, ensuring their
physical and mental well-being.
