New Delhi: Obesity is a growing epidemic worldwide and a leading cause of death alongside heart disease and smoking. Bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB), is the most effective treatment for obesity. According to a new research from Binghamton University, State University of New York, many patients exhibit a reduction in taste preference for sweet and fatty foods with RYGB, although this effect may only be temporary.
Professor Patricia DiLorenzo said, “People who have this surgery are what we call morbidly obese, meaning that they are at least 100 pounds overweight, and in many cases are diabetic. It’s life or death for them.” RYGB makes the stomach much smaller into what is called a pouch. This pouch bypasses part of the small intestine, so when you eat, your food enters a smaller stomach and empties right into the small intestine.
This means that people cannot eat large meals anymore, leading to weight loss. However, taste and odour preferences are also known to change after surgery, and their potential involvement with the noted weight loss is a question of the study.
However, these altered food preferences generally trend back towards pre-surgery preferences over time. Additionally, the rate of weight loss lessens as time increases post-surgery. Despite the risk for some patients to regain weight post-surgery, the majority of patients successfully lose and keep the weight off.
The study is presented in the journal- PLOS ONE.
