About Weight Loss Surgery or Bariatric Surgery

Surgery to achieve weight loss is only done when diet, exercize and medications have not given the wanted result after long time and the person has so much excessive fat that it threatens the life, or makes him severely handicapped.

Candidates or this type of surgery must according to traditional criteria eithr have a BMI (body mass index) of 40 when tghe obesity do not yet have created serious complications. If the obesity allready gives complication, surgry will often be done with a BMI of 35 or more. There is however a movement to perform this type of surgery for patients with a BMI down to 30.

Such sururgery works by restricting physically the amount of nutrients taken up from the intestines, which can be done either by hindering the patient to consume as much food as before or by hindering much of the nutrients taken in by mouth from being taken up from the digestive tract. This can be done by sseveral methods:

GASTRIC BANDING SURGERY

By this method an adjustable ring is mounted around the upper part of the stomach ventricle that restricts the passage of food. The surgery is easy to perform, is usually done with a minimally invasive approach through small holes, can be reversed and requires short hospital stay.

After the surgery the patient is able to eat only slowly so that the total amount eaten each day diminishes greatly. The slow rate of food intake also gives hormons signalling satiety time to work before the stomach is full.

GASTRIC SLEEVE SURGERY

By this method one cuts away a great portion of the stomach ventricle from that part where the esophagus hoes in and the small intestine goes out. This part ois sewn togeather so that it resembles a tube. The part cut loose, is usualy taken out.

After the surgery the patient will be able only to eat small meals, but he also must eat some more meals a day than before. The small intestine will however keep its full capacity to take up nutrients.

GASTRIC BYPASS SURGERY

By this method one separates the upper part of the stomach ventricle from the rest of the stomach. This upper parte is then connected into the samall intestine a long way further down. This creates an Y-structure. One arm of the Y goes up to the stomach ventricle. No food will pass through this arm, but the secretes from the liver will be delivered through it down to the rest of the small intestine. The other arm of the structure is the connection up to the upper stomach part and esophagus.

After this most of the ventricle and the upper portion of the small intestine will stay separated from the rest of the digestive tract, but can be reconnected again if wanted.

After this surgery, the patient will only have a small ventricle volume he can fill during meals and the space for uptake of nutrients will also be reduced.

SPECIAL CARE AFTER SURGERY

Since the digestive system has less ability to take up nutrients after these types of surgery, the patient must live on a diet rich in protein, vitamins and minerals. He must take an extra supply of vitamins and minerals, and especially vitamin B12. He must also eat more often each day to get the amount of food and water he needs.

ADVERSE EFFECTS AND DANGERS WITH WEIGHT LOSS SURGERY

The changes in the stomach ventricle will of cource be uncomfortable to the patient, because he cannot eat so much as before. There is also the danger that he will be able to eat only too little, othat he looses more weight than wanted.

The manipulations of the small intestine have the advantage that the patient can eat as before. However, it can cause too less of vital nutrients to be absorbed, like minerals and vitamins. The absorbtion capacity can also get so low that he looses too much weight. By hard physical activity in warm weather, the patient can also get severely dehydrated because he absobes too little of the fluid he consumes.

The patient can also get into the situation that he must eat unplesantly great amount of food to get all the nutrients needed.
