With the possible exception of the rare patient who develops obstruction of the stomach outlet, it is unlikely you will ever lose too much weight. On the other hand, snacking and high calories liquids can put on weight readily.
Because to the large amount of fat between the skin and the true body, the skin will surely sag as fat is removed. Since the weight loss is rapid in the first 6 months, the skin cannot keep up the pace and indeed does sag. During this period, however, elasticity of the skin is improving and the skin is also shrinking. This process will continue over the next one or two years and your appearance will be worse at about 6 months, although it will improve gradually thereafter. Regular and progressive exercise will also help the appearance of the sagged skin. The skin of younger bypass surgery patients recovers more rapidly. Some patients may wish to have excess skin surgically removed at a later time.
No, definitely not! The sagging is related to the total amount of weight loss. It only appears worse during the rapid weight loss phase. If anything is done to slow down weight loss in the initial three to nine months, the opportunity for easy weight loss while the pouch is very small, will be lost forever.
It remains in place and its ability to function remains intact. The muscles may loose some of there contractile power, but each cell is still there an capable of functioning in the unlikely event it should be call upon.
It is possible, but doing so would result in regaining most of all of the lost weight. We have never been asked to reverse the operation.
Dumping is the condition that results when sweets very rapidly empty out of the stomach into the jejunum through the small pouch. Sweets have a characteristic called "hyperosmolarity" which means they have a high concentration of particles in solution. One of the functions of a normal stomach is to act as a reservoir where food will be held and emptied into the small bowel bit by bit, rather than "dumped" into the digestive/absorptive part of the intestine. If the latter were to occur, the jejunum would react by sending off chemical signals to stop the intake of such materials on such a rapid basis. These chemical signals cause nausea, dizziness, and faintness. The chemical signals are relatively harmless but they should not be repeated in orders to avoid these unpleasant symptoms. This might be a bad thing if one continued to crave sweets, but most sweet lovers will come to loathe sweets after this symptom occurs a few times. The avoidance of sweets under the circumstances is called an "aversion reaction." The avoidance of sweets by the patient who has had a gastric bypass procedure probably accounts for a significant part of the weight loss results.
Most gas is simply the 80% of swallowed air which is nitrogen, the oxygen part of it being absorbed. Some people, more than others, tend to be air-swallowers, and swallow air during eating, talking, ect. Nitrogen, which constitutes 80% of the air swallowed, must go all the way through the intestinal tract to the rectum. Others may have "irritable bowel syndrome" in which, because of anxiety , the colon becomes irritated, causing cramps, with alternating constipation and diarrhea.
These symptoms can be reduced by the use of bran or other stool softeners to keep the stool quite soft and the work of the colon to a minimum. The tranquilizer effect of aerobic exercise also benefits the irritated bowel.
It can be made smaller by another operation, but it is more difficult and dangerous than the first because of the degree of scaring around the stomach due to the previous surgery.
The size of the pouch after surgery is the most difficult parameter to measure. An upper GI series, endoscopy (looking at the stomach directly through a tube), and other test have not been of much help.
Some patients may come to feel frustrated and discouraged after weight levels off but is yet too high, or when slow weight regain occurs. This cannot go uncorrected. While responsibility to continue making progress and to avoid regression remains with the patient, help will be available. It is important to constantly realize that the pouch is there only as a tool and must be used properly. If this leveling off or regression happens, support may be necessary and it is important to come back to see us so we may evaluate your case. We will then go back into your history and review the thing you have learned in your first evaluation and from this booklet. Re-evaluation does not mean either the operation or you have failed. We are aware it often requires considerable time and effort to change the habits of a lifetime. We understand your predicament. We want to be viewed not as a critic, but as a coach and friend.
