Obesity Information

Obesity is extremely common in our society and there are many problems that are either caused by, or worsened by, obesity. These include high blood pressure, high cholesterol, diabetes, gallstones, heart disease and vascular disease. There are many different weight loss treatments available, one of which is surgery.
