How and why you lose weight with this surgery

The Roux-en-Y Gastric Bypass Surgery helps you lose weight in three ways...
 

1. You eat less (Volume restriction)

With a separate small stomach pouch, you feel full after eating a small amount of food. You will be physically unable to over eat because your pouch will become so uncomfortable that you may in fact vomit. The desire to overeat may still be present though and post op patients call this 'head hunger' where your brain is forcing old habits on you whereas your body is telling you that it has had enough food. In time and with self discipline you can retrain your head to accept that you are full on very little.

2. Your appetite changes (Behaviour modification)

 The procedure reinforces a change in your eating habits. After the procedure, most patients find that their body will not easily tolerate foods that are high in refined sugars and fats. With this built-in control, called "the dumping syndrome," which produces short-term discomfort, you naturally learn to avoid these foods. However, not all patients experience Dumping Syndrome - it seems very varied between surgeons.

3. You absorb fewer calories (Malabsorption)

Food bypasses part of the small intestine and digestion occurs in the lower part of the small intestine. These two factors reduce the amount of calories your body absorbs from the food you eat.
 

The reduced stomach pouch size, change in eating habits and absorption of fewer calories allow patients to be successful at long-term weight loss, as opposed to short term weight loss programs or diets that rely on willpower, costly meal  replacements, or dietary supplements. The statistics show that only 1 in 100 slimmers attending classes alone will succeed in achieving and maintaining their weight loss goal. 99 of them will fail to meet the goal or keep the weight off. With the gastric bypass, once you have mastered the head hunger, and learnt to listen when your body says no to sugary foods, high fat foods and simply too much food, then you will have this obesity disease beaten.
