Losing weight and maintaining a healthy weight can have significant long-term health benefits, even for those who may regain some of the weight lost. A recent study conducted at the University of Gothenburg has shed light on the impact of weight regain on health outcomes, particularly in individuals who have undergone weight-loss surgery.
Published in The Lancet Regional Health—Europe, the study focused on analyzing mortality rates, cardiovascular disease, cancer risk, and microvascular disease in individuals who had experienced substantial weight loss followed by weight regain. The research included 1,346 participants from the Swedish Obese Subjects (SOS) study, which is known for its comprehensive exploration of the effects of bariatric surgery versus traditional obesity treatment.
The findings revealed that individuals who had regained at least 20% of the weight lost after one year of surgery were compared to those who had maintained their lower weight or experienced minimal weight gain. Interestingly, the study showed that there were no significant differences in cancer risk and life expectancy between the two groups. However, individuals who regained weight were found to be at a higher risk for microvascular disease, with a noticeable increase in incidence rates compared to those who maintained their lower weight.
In terms of cardiovascular diseases, such as heart attacks, strokes, and heart failure, the study also indicated a higher incidence rate among individuals who had regained a significant amount of weight. This highlights the importance of providing effective support to prevent substantial weight gain and the associated health risks.
Lead researcher Kajsa Sjöholm, an associate professor at the Department of Molecular and Clinical Medicine at Sahlgrenska Academy, emphasized the long-lasting positive effects of weight loss, even for individuals who may regain some weight. Sjöholm underscored the need for ongoing support to help patients maintain a healthy weight and prevent potential health complications.
Overall, the study provides valuable insights into the relationship between weight loss, weight regain, and long-term health outcomes. By understanding the impact of weight fluctuations on various health parameters, healthcare providers can better tailor interventions to support individuals in achieving and sustaining a healthy weight for improved overall well-being.
