Weight loss surgeries may account for future health problems as they have been linked with potential food intolerance and other issues by a recent study.
Bariatric surgeries or weight loss surgeries are based on various procedures. Most of those to undergo such surgeries were diagnosed with obesity. The weight loss is achieved through a number of methods.
Gastric bands or a partial removal of a stomach portion are amongst the most common such practices.
The United States National Institutes of Health has issued a series of regulation. Weight loss surgery patients must have a specific BMI. Their BMI or body mass index must be of at least 40. Those with a lower BMI but coexisting health issues can also be operated.
Long-term effects of such surgeries have been seen to mark a cardiovascular risk factor improvement. Long-term weight loss has also been registered.
As well as a potential recovery from diabetes. Mortality risks were also seen to fall to 23 percent from the previous 40 percent.
However, a new study has gone to reveal its potential long-term adverse reactions and side effects.
The research team was composed of MC Slotervaart in the Netherlands. It was led by Dr. Thomas Boerlage. Study results were published in the British Journal of Surgery.
Research was based on 249 cases of extreme obesity. These patients underwent a laparoscopic Roux-en-Y gastric bypass. Such a weight loss surgery is set to reduce their stomach. It would turn it into a small pouch, approximately as large as an egg.
The study compared data from such patients to that from a control group. This latter included 295 obese patients. However, these did not undergo weight loss surgeries.
Post-operatory studies were carried out after two years. They went to analyze the patients’ health condition. On average, results showed a 31 percent body weight reduction.
However, when compared to the control group, they also had some issue. Gastric bypass patients revealed an intolerance to several foods. They were also reported to be more likely to suffer from indigestion.
The aforementioned lead, Boerlage, went to offer some details. According to him, the Roux-en-Y method was known to potentially cause issues.
More exactly, previous studies showed that it might aggravate gastrointestinal symptoms. Still, most such studies only had a one year post-op time span.
The current study was carried out two years after the surgeries. Both the operated and control group patients were involved. They were asked around 16 gastrointestinal symptoms related questions.
As such, they reached the following average. The post-operation group exhibited around 2.2 symptoms. Control group patients only presented about 1.8 symptoms.
Around 71 percent of the post-operative patients accused food intolerance. Only 17 percent of the control group patients had such an issue.
The food intolerances were seen to vary. Research determined that there is no relation between the weight loss ratio and the number of intolerances.
However, there are some factors that have to be taken into consideration when analyzing the study results. For example, the research base was quite small. Another limitation is the lack of pre-surgery data.
The study authors noted their importance. Such information could have helped better establish which or if the digestive or gastrointestinal issues were directly linked to the surgery.
Weight loss surgery patients, especially gastric bypass ones, already receive a series of advice. They should avoid certain food types that may be harder to digest.
Another factor to be taken into consideration is a method change. Since the study was initiated, a new method has become more commonly used.
Reports show that sleeve gastrectomies make up more weight loss surgeries nowadays. This also helps reduce the size of the stomach. However, it accounts for a bigger size, about the dimensions of a banana.
