The advent of technology and comparatively easier lifestyle of an average human has accentuated various health hazards. Obesity is one of those. Over the past few years, it has become a growing concern.
Obesity, in general, means accumulating excess of body fat around various parts of the body. In medical terms, a person is said to be obese, if the BMI has exceeded the level of 30 and the body weight is 20% higher than it should normally be.
The Lap band techniques or surgery is a popular method that weight loss centres have been using to help individuals lose weight and stay in shape.
A lap band is an adjustable band made of silicone which is placed around the upper part of the stomach during laparoscopy to curtail food intake. A small port is placed along with the band under the skin of stomach for adjusting the tightness of the band.
The lap band curtails the amount of food entering the stomach and magnifies the feeling of being full. It also extends the stomach emptying time. The signal of satiety to the brain is sent via a small pouch formed by the band in the stomach.
The food choices govern the weight loss. But approximately 40-60% of excess body fat can be lost in a year.
It is done using a laparoscopic technique. The procedure involves making 3 to 5 small incisions of 1mm in length. A small camera attached to a tube and is inserted from one incision for viewing the procedure on screen. The surgical instruments and band are integrated with each other. The Lap band is placed around the upper part of the stomach with suture. The port is also placed in the wall of abdomen for adjusting the tightness of band.
The recovery period varies. Initially a discomfort is experienced that disappears after a week. Complete recovery takes a period of 6-8 weeks.
