The most prevalent type of respiratory difficulty connected with obesity is obstructive sleep apnea (OSA). When there is too much fat around the neck and throat, it obstructs our breathing during sleep, causing it to become shallow. 

When we are deeply asleep, we stop breathing altogether, which is known as apnea. Obesity is a crucial risk factor for OSA development, and losing weight improves obstructive sleep apnea in most people.


An expert gastroenterologist can best handle obstructive sleep apnea conditions. Dr. Samrat Jankar is a lead consultant and head of the Surgical Gastroenterology Department and Minimally Invasive Surgery at Symbiosis University Hospital and Research Centre, Lavale Pune. 


Dr. Jankar specializes in investigating and treating all gastrointestinal problems. He is an expert in advanced Gastric Bypass Surgery, laparoscopic surgery, GI cancer surgery, colorectal surgery, bariatric surgery, and abdominal wall reconstruction surgery.

Gastric Bypass Surgery

Open surgery: Your surgeon will make a large incision to open your belly—the bypass works on your stomach, small intestine, and other organs.


Laparoscopy Surgery: In this surgery, experts use a tiny camera called a laparoscope. The surgeon inserts a camera in your abdomen. The scope allows the surgeon to see inside your stomach. The surgery is called laparoscopy.
