Weight loss surgeries



If you are very overweight and cannot lose a pounds in a eating healthy food and exercise, surgery may be an option for you. Surgery is usually men who are at least 100 pounds overweight and women who are at least 80 pounds overweight. If you are a bit less overweight, surgery may still be an option if you also have diabetes, heart disease or sleep apnea. Lose Weight limit the amount of food can be taken in some functions also limit the amount of food can be thawed. Multi-section to lose weight fast. If you follow the diet and exercise recommendations, you can keep most of the weight off. Surgery has risks and complications, but also infections, hernias and blood clots.



Severe obesity is a chronic disease that is very difficult to treat. In some people, weight loss surgery ,bariatric surgery, or to help by restricting intake of food or interrupting digestive processes. But remember that weight loss surgery is serious business. You should clearly understand the advantages and disadvantages of the procedures prior to decision making.

To understand how weight loss works,first you must need to know, how the normal functions of the digestive process.



Normally, as  your food moves along the digestive tract, the arrival of gastric acid and enzymes appropriate to the right place at the right time to digest and it  absorbs calories and nutrients. After chewing and swallow food, it moves into the esophagus to the stomach, where a strong acid help in digestive process. The stomach can hold about 3 pints of food at once. When  contents  of stomach move to the duodenum, the first part of  of the small intestine, bile and pancreatic juices accelerate digestion. Most of the iron and calcium in the foods  is absorbed in the duodenum. In the jejunum and ileum, the other two parts of nearly twenty feet of small intestine, complete the absorption of almost all calories and nutrients. The food particles that could not be digested in the small intestine can stored in the large intestine (consisting of the ascending colon, transverse colon, descending colon, sigmoid colon and rectum) until disposal.





Obesity surgery requires changes in the stomach and / or small intestine.




The concept of gastric surgery to control obesity, was born in the results of operations for cancer or severe ulcers that removed a large part of the stomach or part of small intestine. Since receiving these procedures tend to lose weight after surgery, some doctors began to use these procedures with severe obesity. The first measure, which is widely used for obesity, type of intestinal bypass. This measure was introduced 40 years ago, caused weight loss due to malabsorption.



The idea was that patient can eat in large amount of food, which are poorly digested or passed along too fast for the body to absorb many calories. The problem with this type of surgery is causing a loss of essential nutrients (malnutrition) and its adverse effects are unpredictable and sometimes fatal. The original type of intestinal bypass operation is no longer used. Surgeons now use other different type of techniques that can produce weight loss primarily by limiting the amount in the stomach can hold. 


There are two types of surgical procedures used to promote weight loss are:



Restrictive surgery  :  In these procedures, the stomach is made smaller. The part of stomach is removed or closed which limits the amount of food can be and makes you feel full.

Malabsorptive surgery :   Most of the digestion and absorption occurs in the small intestine. Operation in this area is shortened small bowel changes and / or, if incorporated into the stomach, limiting the amount of food which is completely digested or absorbed (causing malabsorption). These operations are now under way with limited surgery.



Through dietary restriction, malabsorption, or both, you can lose weight since less food either goes to the stomach or small intestine is closed long enough to digest and absorb.




Right candidates for  weight loss surgery



If you have a body mass index (BMI) 40 or more,that is about 100 pounds overweight for men and about 80 pounds for women, are seriously overweight, and therefore the candidate for the surgery of loss of weight. Obesity surgery can also be an option for people with BMI between 35 and 40 who suffer from problems associated with obesity (e.g. severe sleep apnea, heart disease obesity related or diabetes ). For these people, there is no risk of dying from surgery may be higher than the risk of possible complications of the procedures.



Remember, as in other treatments for obesity, results can vary. In many cases, patients must demonstrate that their attempts at weight loss diet have been ineffective before surgery will be approved. A psychological evaluation could be required by physicians to determine possible answer to your weight loss and some changes in image of body. Most f the surgeons require patients to demonstrate serious motivation and a clear understanding of the extent of food, exercise and medical guidelines to follow for the rest of their life after surgery for weight loss. In addition, studies to assess the health of cardiovascular system and hormonal. Nutritional counseling is also a necessary before and after surgery.



For patients who remain severely obese after non-surgical approaches for weight loss have failed, or for patients with obesity-related disease, surgery could be an appropriate option for treatment. But in most patients,its a great effort to control weight, such as changes in eating habits, changing lifestyles and increasing physical activity are more appropriate.
