A recent Australian study has found that weight loss surgery, also known as bariatric surgery, is a safe and effective way to help people lose weight and reduce their need for diabetes medication.
The study, led by researchers from Monash University and the University of Sydney, analyzed data from 122,567 patients who had weight loss surgery in Australia between 2012 and 2021. The results show that most people experienced significant weight loss and many who had diabetes before surgery no longer needed medication afterward.
Weight loss surgery is usually recommended for people who are severely overweight and have been unable to lose weight through diet and exercise alone. The procedures work by reducing the size of the stomach, which helps people eat less and absorb fewer calories. The study looked at four common types of weight loss surgery:
- One-anastomosis gastric bypass: Patients lost an average of 34.88% of their total body weight.
- Roux-en-Y gastric bypass: Patients lost 30.73%.
- Sleeve gastrectomy: Patients lost 26.5%.
- Adjustable gastric banding: Patients lost 17.6%.
These results were measured five years after the surgeries, showing that the weight loss was long-lasting.
One of the major benefits of weight loss surgery is its effect on diabetes. Before surgery, 13.6% of the patients were taking diabetes medication. Among those who were followed up one year later, 71.6% no longer needed any diabetes medication.
After five years, 61% of those who were still in the study remained free of diabetes medication. This suggests that the surgery not only helps with weight loss but also improves blood sugar control.
The study also found that the risk of complications from the surgery was low. Within the first 90 days after surgery, only 3.6% of patients experienced complications such as hospital readmission, intensive care treatment, or needing another surgery.
The researchers said this rate is similar to that of other common surgeries, such as gallbladder removal, making bariatric surgery a safe option for most patients.
Professor Wendy Brown, a surgeon from Monash University and the lead author of the study, emphasized that this research provides strong evidence that weight loss surgery is effective not only in specialized hospitals but also in regular healthcare settings.
She said that the results should reassure patients, their families, and health insurance providers that the surgery is both safe and beneficial.
She also pointed out that this surgery can significantly improve a person’s overall health and quality of life. Many people who are severely overweight struggle with other health problems, such as joint pain, heart disease, and sleep issues. Losing a significant amount of weight can reduce these problems and make everyday activities easier.
One of the most important findings of the study is that the positive effects of weight loss surgery last for many years. Many previous studies were conducted in highly specialized hospitals, but this research shows that even in regular hospitals and clinics, patients still achieve long-term success.
This means that more people who are struggling with obesity and diabetes could benefit from these procedures.
Another key takeaway from the study is that bariatric surgery is much safer than many people assume. In the past, obesity was considered a major risk factor for surgery complications, but this study shows that most patients recover well and have very few problems after the operation.
According to Professor Brown, this makes weight loss surgery a reliable option for people who have been unable to lose weight through other methods.
The researchers gathered their data from the Australia and New Zealand Bariatric Surgery Registry, which tracks information on patient outcomes to ensure the safety and effectiveness of weight loss procedures.
The study included patients from across Australia and showed that the average age of people undergoing surgery was 44 years old, with most being women. The average body mass index (BMI) before surgery was 41.7, which is classified as severe obesity.
Going forward, the research team plans to study patients who need follow-up surgeries, as well as how different treatment approaches affect people with both obesity and diabetes. They also aim to collect more patient-reported experiences to get a better understanding of how the surgery impacts their daily lives.
Review and Analysis
This study provides strong evidence that weight loss surgery is a safe and effective long-term solution for obesity and related health problems, particularly diabetes. The large number of patients included in the research makes the findings highly reliable. The results confirm that most patients experience lasting weight loss and significant health improvements.
One of the most important findings is that a majority of diabetes patients could stop taking medication after surgery. This has major implications not only for individuals but also for healthcare systems, as it could reduce the cost of treating diabetes in the long run.
Given the increasing rates of obesity and diabetes worldwide, weight loss surgery may become an even more important tool in managing these health issues.
The safety data is also reassuring. With a low rate of complications, the risks of surgery appear to be minimal compared to the benefits. Many people might fear that weight loss surgery is dangerous, but this study helps to dispel that concern.
However, while the results are promising, it is important to note that surgery is not a quick fix. Patients still need to make long-term lifestyle changes to maintain their weight loss and health benefits. In addition, not everyone is eligible for the surgery, and it is usually recommended only for those with severe obesity or serious health conditions related to their weight.
Overall, this study adds valuable information to the growing evidence that bariatric surgery is an effective option for long-term weight management and diabetes treatment. It provides a strong case for making weight loss surgery more widely available to those who need it.
