Large weight loss and weight swings may predict increased mortality and CVD risk in type 2 diabetes

The key findings of this study were as follows:

1. The systematic review contained thirty eligible papers, and 13 of them were included in the meta-analysis.

2. Weight loss of more than 10% was linked to an increased risk of all-cause mortality, a composite of major CV events, and CV death in T2DM patients.

3. Moderate weight reduction had no correlation with all-cause mortality or CV outcomes. Weight variation was linked to an increased risk of all-cause death.

In conclusion, large weight loss and weight swings may be indicators of an elevated risk of mortality and CV events in T2DM patients. Weight change as a global indicator for physical state may indicate the overall influence of many pathophysiologic processes, suggesting illness development and deterioration of health status. Weight loss should not be the exclusive goal of T2DM treatment. Maintaining a healthy lifestyle and a constant weight may be more essential.
