Gastric bypass surgery is generally a safe operation. However, in order for you to make an informed decision and give consent for the operation, you need to be aware of the possible side-effects and the risk of complications of this procedure.

Weight Loss Injections
In recent years weight loss injections such as Wegovy, Ozempic and Mounjaro have proved a revolutionary solution for those struggling with obesity. The injections primarily work by mimicking the actions of certain hormones that regulate appetite and glucose metabolism, helping to reduce hunger, increase feelings of fullness and improve blood sugar control, thus aiding significant weight loss.
Although weight loss injections are effective, their success is dependent on proper screening and a comprehensive treatment plan. As an Obesity Specialist, Mr Agrawal offers expertise and experience, holistic care, safety and monitoring of side effects and access to the latest treatments. This personalised approach ensures that patients receive the best possible care on their journey to a healthier weight and improved quality of life.

Weight loss surgery
Gastric sleeve surgery
Also known as sleeve gastrectomy, gastric sleeve surgery is a procedure to reduce the size of the stomach by approximately 75-85%. Reducing the size of the stomach not only restricts the amount that can be eaten, but also reduces the appetite by decreasing the production of appetite stimulating hormones in the stomach.
Gastric sleeve surgery is performed laparoscopically through four or five small keyhole incisions. It takes one to two hours under general anaesthetic. The remaining portion of stomach is shaped into a sleeve or tube about the size of a banana and sealed using staples. Recovery time is two to three weeks including a post-surgery stay in hospital of two to three days.
On average, a person will lose 60-70% of their excess body weight within a year of gastric sleeve surgery. There are no dietary restrictions following gastric sleeve surgery, however, to enjoy the maximum benefits of the surgery, it is important to follow a healthy diet plan and consume meals that contain less fat.
Other weight loss options
Mr Agrawal also performs gastric band surgery and gastric bypass surgery.
Gastric band surgery involves placement of a band around the stomach, which helps reduce food intake and results in a quicker sensation of fullness. It is a reversible process resulting in 50-60% excess weight loss.
Gastric bypass is a procedure to reduce the size of the stomach and reroute a portion of the digestive system. This results in restricted meal portions and the body absorbing less food. It is a non-reversible process resulting in 70-80% weight loss.
