Bariatric surgery

Reduction of the stomach - a surgery that improves the quality of life

What is bariatric surgery

Bariatric surgery is a surgery aimed to reduce or modify the stomach; it helps to change the processes of food processing in the body.
Bariatric surgery is a modern, safe and effective treatment in case of obesity and metabolic disorders. After bariatric surgery, a patient consumes and processes less food, therefore, the body does not accumulate excess fat, which helps to lose up to 80% of excess weight over 1 – 3 years.

When is bariatric surgery recommended?

If a person’s body mass index (BMI) is close to 34, overweight is increasing, and other methods of weight loss have failed, bariatric surgery is an option. The surgery gives a number of advantages in case of type 2 diabetes mellitus and high blood pressure. Apart from losing weight, it’s also easier to manage and keep both blood pressure and sugar level within limits.

The doctor individually evaluates the need for surgery for each patient.

Body mass index

Body mass index or BMI is one of the most popular indicators to measure level of obesity. Using BMI, the ratio of body weight to height is calculated. It is obtained by dividing body weight (in kilograms) by the square of body height (in meters). For example, a 1.75 m tall and 60 kg light woman will have a BMI:
60 / (1,75)2 = 19,59.
BMI calculation formula: BMI = weight (kg) ÷ height (m)2
According to the accepted guidelines, it is considered that BMI of 18.5 to 24.99 indicates normal body weight. If BMI is higher, it is classified as overweight, obese. To be eligible for bariatric surgery, a patient must have a body mass index (BMI) of at least 34.

Surgery results

Short recovery time
Patients lose up to 80% of excess weight within 24 months
Long-lasting result
Improved overall health

The research results indicate that 60% of the lost weight has not returned within 10-14 years after surgery. After surgery, most of the illnesses related to obesity are significantly reduced or disappear:

  • Type 2 diabetes mellitus
  • High blood pressure
  • Sleep apnea
  • Depression
  • Back pain
  • Dyslipidemia
  • Joint problems

The patient has a feeling of fullness after eating a small amount of food; the patient’s self-esteem and well-being are improved. There are no restrictions for sports, professional activities or hobbies.

How is bariatric surgery performed?

Bariatric surgery is performed laparoscopically, when tools are inserted into the abdominal cavity through small, approximately a centimetre large openings.

  • Significantly reduced operational trauma
  • Short recovery period for the patient
  • Risk of infections and adhesions in the abdominal cavity is reduced
  • Good cosmetic result

Types of bariatric surgeries

There are two most common types of bariatric surgery:

Gist of the surgery

A small gastric pocket is made out of the large stomach, which is connected to the small intestine in its middle part. Less food is required to fill the reduced stomach, and a person feels full faster.

  • Long-lasting weight loss
  • The patient feels full after eating a small amount of food
  • Most of the illnesses related to obesity are reduced or disappear: type 2 diabetes mellitus, high blood pressure, sleep apnoea, depression and back pain
  • Gastric bypass surgery is now recognised as the most effective and best method for long-term weight loss

If the patient carefully monitors their health and takes medication prescribed by the doctor, the risk of complications is minimal. The doctor will give more detailed information about the postoperative stage and the risks at the first consultation.

Stomach resection surgery (vertical gastroplasty surgery)

Gist of the surgery

The surgeon makes a thin, narrow stomach in which food does not stay for a long time and quickly passes into the intestinal tract. The amount of food consumed is reduced and there is no feeling of hunger.

  • Fast and effective way to lose weight
  • At meals, the patient quickly feels full, which reduces the desire to eat frequently
  • Most illnesses related to obesity are reduced or disappear – type 2 diabetes mellitus, high blood pressure, sleep apnoea, depression and back pain

The surgery has a higher surgical risk, as it is necessary to open the stomach and remove a part of it.
During the first meals, it may be difficult to get food into the stomach, and the patient may feel discomfort.
To avoid possible postoperative complications, the patient must follow the surgeon’s recommendations regarding the lifestyle, and should attend regular consultations of the general practitioner. The doctor will give more detailed information about the postoperative stage and the risks at the first consultation.
