When appropriate, weight-loss surgery can result
in dramatic improvements in weight and health:
Please note that significant weight loss is reported to
be higher with roux-en-y gastric by-pass compared to restrictive
procedures alone. Surgery is the most effective means available
for successful long-term weight loss.
You will lose weight rapidly after surgery, typically up
to 6 pounds per week at first, and continue to do so with
the lowest weight occurring in 18 to 24 months. Generally,
those who follow dietary and exercise recommendations keep
most of that weight off 10 years and longer. Besides weight
loss, you will usually experience improvements in comorbidities
as well, here are just a few examples:
- People who are severely obese and have type 2 diabetes
typically see improvement in control of their blood sugar
levels, or blood sugar levels become normal within one
year of surgery.
- High blood pressure disappears in about two-thirds of
those who have weight-reduction surgery.
- lower levels of cholesterol or other fats (lipids) in
the blood for about seven in 10 people.
- Most people who have obstructive sleep apnea enjoy marked
improvement, including less daytime sleepiness.
- Most patients report improvement in mood and other aspects
of psychosocial functioning following surgical treatment.
- Patients with musculoskeletal problems have less pain
and improved mobility.
- Patients report that interpersonal relationships, employment
opportunities, and general quality of life improve dramatically
after surgery.
Some degree of weight regain is common by 2 to 5 years after
operation. It can occur anytime, even years later. This is
influenced by eating behavior and lack of a regular exercise
program.
At that time, your weight will begin to level out, most
likely stabilizing at about 20 to 40 percent above your ideal
body weight. This typically represents a loss of 70-80% of
the extra weight that you started with prior to your surgery.
But more important than the actual number of pounds lost
is the overall improved health you will gain after gastric
bypass surgery. In fact, the true measure of the operation’s
success is the improvement of any weight related comorbidities.
