surgery is one option for a limited number of patients with severe obesity.
It is generally reserved for patients with whom efforts at medical therapy
have failed and who have either a BMI of 35 - 40 and suffer from complications
of obesity or a BMI of more than 40 (100 pounds or more overweight).
Roux-en Y gastric bypass is a tool to assist motivated patients. This
surgery is part of an integrated program that includes diet, physical
activity and behavioral and social support prior to and after surgery.
appropriate for and desiring surgery will receive extensive pre-operative
education regarding this permanent re-arrangement of their digestive
system. In order to obtain the safest lasting weight loss, it is critically
important for potential surgical patients to learn how to utilize their
new "tool" and recognize the signs of potential nutritional
deficiencies and other complications.
operations achieve their results through two methods. The first is restriction.
The small stomach pouch severely limits the amount of food that can
be eaten at any one time without inducing vomiting. The patient has
a sensation of fullness with a limited volume of food. The second method
is malabsorption. The bypassed portion of the small intestine does not
participate in the absorption of nutrients from food. The remaining
shorter length of small intestine is not capable of absorbing all of
the nutrients efficiently. Following roux-en Y bypass, patients eat
less, still feel full and absorb less of what they eat. Calories expended
are greater than calories consumed and the patient loses weight.
I BE HOSPITALIZED?
requires hospitalization for an average of four to six days, depending
on each patient's response to recovery.
DO I PREPARE FOR SURGERY AND WHAT HAPPENS THE DAY OF SURGERY?
As most patients
are admitted to the hospital the day of surgery, the majority of preparation
occurs at home the day prior to the operation. Your surgeon will discuss
the specific pre-operative instructions with you. In general, you may
be on a liquid diet the day before your operation, may be given instructions
for a bowel cleansing procedure and may require an adjustment in your
medications. You will be asked to refrain from eating and drinking after
midnight the night before your operation.
I HAVE PAIN AFTER SURGERY?
advances in medicine, pain still occurs with any operation. Your surgical
team will do their best to alleviate your pain. For the first few days
after operation, you will receive pain relief medications with an intravenous
system. Once you are able to tolerate medications by mouth, your pain
relief medication will be changed to a by-mouth preparation that you
will also have available when you are discharged to home. For most patients,
the pain level rapidly decreases over the first two days while in the
hospital. Most patients are taking few doses of pain relief.
