Restrictive operations are those most used for losing weight. The food is limited by creating a small bag in the top of the stomach where food comes through the oesophagus. The bag keeps initially about 30gr. of food and extends up to 1kg in time. A hole at the bottom of the bag usually has a diameter of approximately 0.6 cm. The hole keeps the emptying of the bagi and give the feeling of “I ate enough” so you eat less.

Limitative surgery for obesity include gastric banding and gastroplastia with vertical banding. Both operations serve only to limit consumption of food. They do not intervene in the normal digestive process, as happens in the case of gastric bypass surgery.

What is gastroplastia with vertical banding?
Known as “capsare the stomach,” this operation is a type of surgery known limitativa of weight control. During the operations, using fasteners or strip to create a small stomach bag.

What are the risks associated with VBG?
VBG’s risks include:
• Erodarea band used to create bag stomach.
• Destruction line captusite used to create bag stomach.
• Scurgerea gastric juice in the abdomen requiring emergency surgery.
• In a small number of people who do the operation (less than 1%), infections can occur or death.

What is gastric banding?
During this procedure, a banda made from a special material is placed around the stomach near the upper end, creating a bag and a small hole in the crossing more than a stomach that remained.
What are the risks of gastric bandingului?
The risks associated with gastric bandajul are similar to the risks associated with VBG.

How to make changes in diet after surgery?
After surgery limitativa, usually can eat only a quarter to half a cup of food without causing discofort or nausea. Lichidele are limited to inghitituri small and should not be mixed with food because the new small stomach is not wide enough for you and food and liquids at the same time.

Information on gastric bypass surgery
Operatiile of gastric bypass combine to create a small bag of stomach to limit food consumption with the construction of a bypass with duoden and other segments of the intestine to cause thin malabsorbtia (decreasing ability to absorb nutrients from food).

What types of gastric bypass surgeries are there?
• Gastric bypass Roux-en-Y (RGB). This operation is the most frequent gastric bypass operation used. First, it creates a small stomach bag by capsarea with a portion of the stomach or bandage vertically. This limited much food you can eat. Then, in the form of the Y thin intestine is attached to the bag to allow food to ocoleasca duodenul. This causes reduced absorption of calories and nutrients. This operation can be done now with a laparoscop (an instrument as a thin telescope to see inside the abdomen) to some people. This involves the execution of small incisions and generally have a less time for recovery.
• Gastric Bypass extensively (diversie biliopancreatica). In May this operation complicated by gastric bypass, portiunea bottom of the stomach is remover. Punga little that remains is connected directly to the final segment of the intestine thin. Although this operation has given good results of lessening, is not so used because of increased risk from nutritional deficiencies.
Operatiile of gastric bypass which causes malabsorbtie and limiting the quantity of food produced more weight loss than limiting operations, which only decrease consumption of food. People who do bypass operations generally lose two-thirds of extra weight in 2 years.

There are risks associated with gastric bypass surgeries?
Yes. People who have passed through this operation risked following:
• Intinderea pungii (stomach to enlarge with time, intinzandu to size before surgery).
• Eroziunea lane (banda to close a part of the stomach is dezintegreaza).
• Destruction captusirii (banda and capsele fall, anuland operation).
• Scurgerea gastric juice in the abdomen
• Deficiencies nutrition which causes health problems.
Gastric bypass surgeries can also cause “dumping syndrome”, in which stomach contents move too quickly through intestinul thin. Symptoms include nausea, weakness, transpiratie, lesin and, occasionally, diarrhoea after lunch, as well as the inability to eat sweets without becoming very weakly. May arise from kidney stones because of losing weight quickly. They can be dissolved with medication taken after surgery.
