What is Obesity?
Obesity is defined as having a body mass index (BMI) of 30 or more. BMI is a measure of your weight relative to your height. Class 1 obesity means a BMI of 30 to 35, class 2 obesity is a BMI of 35 to 40, and class 3 obesity is a BMI of 40 or more. Classes 2 and 3, also called severe obesity, are often difficult to treat with diet and exercise.
What is bariatric surgery?
Bariatric surgery is an operation that helps you lose weight by modifying your digestive system. Some types of bariatric surgeries make your stomach smaller, allowing you to eat and drink less at a time and feel full sooner. Other bariatric surgeries also alter your small intestine, the part of your body that absorbs calories and nutrients from food and drink.
Bariatric surgery may be an option if you are severely obese and have not been able to lose weight or regain lost weight using other methods such as treatment lifestyle or medication. Bariatric surgery may also be an option if you have serious health conditions, such as type 2 diabetes or sleep apnea, related to obesity. Bariatric surgery can improve many of the health problems associated with obesity, especially type 2 diabetes.
Does obesity surgery still work?
Studies show that many people who have bariatric surgery lose an average of about 15-30% of their starting weight, depending on the type of operation. However, no method, including surgery, is sure to produce and maintain weight loss. Some people who have bariatric surgery may not lose as much as they hoped. Over time, some people regain some of the weight they lost. The amount of weight people regain can vary. Factors that affect weight regain can include a person's level of obesity and the type of operation they have had.
Bariatric surgery does not replace healthy habits, but can help you eat fewer calories and be more physically active. Choosing healthy foods and drinks before and after surgery can help you lose more weight and keep it off in the long run. Regular physical activity after surgery also helps keep the weight off. To improve your health, you must commit to adopting healthy lifestyle habits and following the advice of your health care providers.
What are the side effects of bariatric surgery?
Bleeding, infection, leakage from the site where the intestines are sewn up, diarrhea, and blood clots in the legs that can travel to the lungs and heart can be side effects.
Some of the side effects that can occur later include poor nutrient absorption, especially in patients who do not take the vitamins and minerals they have prescribed. In some cases, if patients do not resolve this problem quickly, illnesses can occur with permanent damage to the nervous system. These diseases include pellagra (caused by a lack of vitamin B3 - niacin), beriberi (caused by a lack of vitamin B1 - thiamine) and kwashiorkor (caused by a lack of protein).
Other late issues include strictures (narrowing of bowel connection sites) and hernias (part of an organ that bulges through an area of weak muscle).
Two types of hernias can occur after bariatric surgery in a patient. An incisional hernia is a weakness that sticks out in the connective tissue of the abdominal wall and can cause a blockage in the intestine. An internal hernia occurs when the small intestine is displaced into pockets in the wall of the abdomen. These pockets occur when the intestines are stitched together. Internal hernias are considered more dangerous than incisional ones and require prompt intervention to avoid serious problems.
Some patients may also need emotional support to help them cope with changes in body image and personal relationships that occur after surgery.
