How Weight Loss Surgery Works?
Some weight loss surgeries prevent the stomach from stretching to full size. Some surgeries also bypass part of the intestine, so you can absorb fewer calories and lose weight. Today, most weight loss surgeries use small cuts, known as “Laparoscopic” surgery, instead of a big one. You can’t eat as much afterward, and it takes a life-long commitment to diet and exercise to keep the pounds off. Since it’s a major surgery, there are some risks, too.
Different Types Of Weight Loss Surgeries
There are two groups of weight loss surgery
- Restrictive: The aim of restrictive surgeries is to decrease the size of the stomach, resulting in significantly reduced food intake as it becomes physically impossible to overeat, and slower digestion.
Examples: Laparoscopic Adjustable Gastric Banding & Gastric “Sleeve” Surgery
- Malabsorptive: In addition to shortening the gastrointestinal tract, it reduces the amount of food which can be absorbed, thus have the greatest effect on weight loss today and is the top choice for patients.Examples: Roux-en-Y Gastric Bypass Surgery
Neurological Complications Of Weight Loss Surgery
There are various studies that suggest that there are so many neurological complications after the bariatric surgery. Other than the neurological complications there are also nutritional deficiencies you can experience with the bariatric surgery. The University of Pennsylvania researchers said that the estimated incidence of neurological complications stemming from nutritional deficiencies in the wake of bariatric surgery could be as high as 16% of patients. Common deficiencies include “thiamine (B1), B12, folate, vitamin D, vitamin E, and copper.” The risks for the deficiencies could be traced to “vitamin noncompliance, protracted vomiting, and excessive alcohol consumption.”
The University of Alberta study reported only outcomes for bariatric surgery patients who never attended a post-surgery nutritional clinic. Two of the patients developed the clinical features Parkinson’s disease. Vitamin replacement therapy “resulted in a slow and variable degree of neurologic recovery.” The French researchers stress that nutritional deficiency depends upon the type of surgery performed and the percentage of weight loss. Neurological complications such as encephalopathy (altered mental state, could include decreased cognitive function) are more rare than other complications such as gallstones.
What to expect?
Ask your doctor, how much weight you’re likely to lose and what you’ll need to do to keep up the results. Expect to eat very small meals and get regular exercise. Like any major surgery, there are risks. The most common complications include infections, minor bleeding, ulcers or hernias. Even though very rare, there can be life threatening problems such as blood clots, major bleeding or serious infections. These risks may be higher at surgical centres that don’t do weight loss operations often.
Most people stay in the hospital 2 to 3 days after their surgery. They tend to get back to their normal activities within 2 to 3 weeks. You’ll need to make sure you’re getting enough nutrients, especially if the surgery made it harder for your body to absorb nutrients from food. Doctors often advice women of childbearing age who get weight loss surgery, to avoid pregnancy until their weight becomes stable, as rapid weight loss and nutritional deficiencies can harm a developing baby.
