Obesity is major public health issue in Australia with nearly two-thirds of adults being classified as overweight or obese. This number is on the rise and obesity can leads to a variety of metabolic consequences that impact the quality of life of patients who are overweight.
Causes
Obesity refers to excessive fat accumulation that presents with health risks. In simple terms, it occurs when there is an imbalance between energy intake (eating and drinking) and energy expenditure (physical activity / exercise). The risks for developing obesity include a diet which is low in nutrition and high in energy dense foods and a lack of physical activity or sedentary lifestyle.
Symptoms
Being overweight or obese is a risk factor for many serious and chronic health conditions including some cancers, heart disease, hypertension, asthma, obstructive sleep apnoea, musculoskeletal / joint problems, chronic kidney disease, dementia, diabetes, gall bladder disease, fertility issues and a reduced life expectancy.
The most common way of measuring obesity is by calculating a person’s Body Mass Index (BMI). This is an estimate only and doesn’t take into account age, ethnicity, gender and body composition. It compares your height and weight and is calculated by dividing your weight (in Kg) by your height (in metres squared). Overweight is defined as a BMI between 25 to <30 and Obese is defined as a BMI >30.
Obesity if subdivided into categories: Class 1: BMI 30 to <35, Class 2: BMI 35 to <40, Class 3: BMI >40
Treatment
The surgical management of obesity and improvement in weight and co-morbidity resolution are well accepted treatment options and are performed generally as laparoscopic procedures. Surgery is currently recommended for patients with BMI > 35kg/m 2 (IFSO guidelines). The American Diabetes Society currently recommends surgery as first line treatment for patients with BMI > 40 kg/m 2 or patients with poorly controlled diabetes and BMI > 35kg/m 2 . There are a few different options for weight loss surgery. Total Upper GI Surgery will discuss the options with you and tailor the operation that is suitable for you.
