Obesity

Obesity is not a simple condition of eating too much. It is now recognised that obesity is a serious, chronic disease. Obesity was widely perceived as a symbol of wealth and fertility at other times in history, and still is in some parts of the world. In 2013, the American Medical Association classified obesity as a disease which leads to many comorbidities like diabetes, high BP (hypertension), cholesterol, infertility, PCOS (PCOD), arthritis, sleep apnea etc. Obesity is a leading preventable cause of death worldwide, with a change in lifestyle there is increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century.

Causes of Obesity

Here’s a very simple explanation of how you put on weight and will lose weight with surgery. Your body needs the energy to function and your energy source is the food that you eat. A normal weight person successfully balances their energy intake (food eaten) with their energy requirements (daily activity). In other words, they burn up all the energy provided by the food they eat and stay slim. At an individual level, change in lifestyle i.e. combination of excessive food energy intake and a lack of physical activity is thought to explain most cases of obesity. A limited number of cases are due primarily to genetics, medical reasons, or psychiatric illness. In contrast, increasing rates of obesity at a societal level are felt to be due to an easily accessible and palatable diet, increased reliance on cars, and mechanised manufacturing.

Consequences of Obesity or Why Treat Obesity

The costs linked with treating obesity and its related health conditions are enormous. Putting the costs aside, the main concern regarding obesity is the impact it has on health. Almost all body systems are affected by obesity. Being overweight can also shorten your life. On average obese people are likely to die 10 years earlier than those who are not overweight, preventing many from reaching retirement age. The heavier you are and the longer you have been overweight the greater the risk If you are obese, severely obese, or morbidly obese, you may have Major health risks.

What is obesity or bariatric surgery ?

Bariatric surgery, also known as weight loss surgery, refers to the operations designed to reduce weight (bariatric come from the Greek meaning pressure or weight). Operations may restrict the amount you are able to eat (restrictive operations such as the gastric band sleeve gastrectomy) or both restrict the amount you can eat and reduce the amount you can absorb (gastric bypass, mini gastric bypass or duodenal switch). The term does not include procedures for surgical removal of body fat such as liposuction or abdominoplasty (tummy tuck).

Why do Bariatric Surgery ?

There can therefore be many benefits to health with weight loss, particularly after obesity surgery. Scientific research demonstrated that obesity surgery can reduce health problems considerably, as shown in the table below:

One study, conducted in Sweden, demonstrated quite clearly the differences in health between a group of obese patients who underwent surgery and those that did not.

Types of Bariatric surgery

We at Obesity Care offer a wide range of surgical procedures such as gastric banding, Roux-en-Y bypass (gastric bypass), sleeve gastrectomy and Gastric Balloon. All operations are performed laparoscopically (keyhole surgery), which will help you to get up and around and back to normal as soon as possible after surgery. One of the mainstays of our service is the multidisciplinary team. Each team member has his or her own role and all together we ensure you are fully informed about weight loss surgery and that your operation is performed in the safest possible environment. Your safety is our first priority.

How surgery works ?

Obesity surgery works by helping to reduce the number of calories that are available in your body. There are two ways this can be achieved surgically :

  • Restriction – by reducing the size of the stomach, only small meals can be eaten and the appetite is satisfied
  • Malabsorption – by bypassing part of the small intestine, less calories from food are absorbed by the body

What is laparoscopic gastric banding?

  • An inflatable silicone band that is placed around the top part of the stomach to create a pouch
  • Inserted using keyhole (laparoscopic) surgery, this only leaves a few small scars.
  • The laparoscopic gastric band restricts the amount of food that can be eaten.
  • Attached to the gastric band is a port which is placed just under the skin. The port can be accessed with a needle to inflate or deflate the gastric band after surgery.

Advantages

  • You can expect to lose roughly 50-60 percent of your excess weight.
  • The amount of food that can be consumed at a meal is restricted.
  • The band can potentially be removed in the future. The aim however, is to leave in place for life as removal will result in weight regain.
