Trimming Intestine May Trigger Better Insulin Absorption: Doctors
Quoting studies from Sweden, US and UK, London–based Dr Torsten Olbers, senior consultant, Imperial College, London said diabetes had been cured in many patients over a period of time and in several others there was a substantial improvement in the quality of life. "There have been cases of diabetics (type–2) not needing insulin after a bariatric surgery. Some may take time, while several others need to take only lower doses of insulin after," said Dr Olbers who is on a visit to the city.
Dr Olbers will be speaking on the effects of bariatric surgery at a workshop organised by Apollo Hospitals on Saturday. Type–2 diabetes, a lifestyle disorder, is usually triggered by obesity and it becomes difficult to maintain sugar levels even with insulin if patients do not lose weight. As a last resort for weight management, one of the three most common bariatric procedures – band, bypass or sleeve –is performed where the volume of the stomach is reduced intake by at least 80%.
Delhi–based diabetologist Dr Anoop Misra says the observation makes sense. "Bariatric surgery results in reduction of agents in the stomach that stimulates appetite. Moreover, it increases some other secretions of the intestine that aid better absorption of insulin," he says.
Dr Prasanna Kumar Reddy of Apollo Hospitals cites the case of his patient M Gowtham. Weighing 163kg, Gowtham had diabetes and hypertension before he underwent a bariatric surgery. "Not only has his weight has come down to 93 kg, his blood sugar has also stabilised without insulin injections," said Dr Reddy. "I feel like a normal human being now. I do everything I have been just wanting to do for the past 20 years," said Gowtham.
However, surgeons warn that patients should be chosen carefully for the surgery. "It’s not a surgery for people with normal weight. And there are risks . At least one in 20 patients can develop complications like bleeding and leakage. It could cause death in one in 500 patients, a risk comparable to any other surgery. And in some people there is even resurgence of obesity," said Dr Olbers.
