Up to 300 million people have a BMI over 30kg/m2. Obesity is the cause of many serious diseases, such as type 2 diabetes, hypertension and NAFLD. Bariatric surgery is the only effective method of achieving weight loss in patients with morbid obesity. The aim of the study is to assess the impact of bariatric surgery on non-alcoholic fatty liver disease in patients operated on due to morbid obesity.
Investigators include 20 patients qualified for the bariatric procedure with BMI \> 40 kg/m2 or a BMI \> 35kg/m2 with the presence of comorbidities. The average body weight in the group was 143.85kg with an average BMI of 49.16kg/m2. Before the procedure, investigators evaluated the severity of the non-alcoholic fatty liver disease in each patient using the Sherif Saadeh ultrasound scale. Investigators also evaluated the levels of the liver enzymes. Follow up was performed twelve months after surgery.
