Diabetes T2 – Reduces risk of diabetic complications

Reduces risk of diabetic complications

Evidence summary

Few studies, and no RCTS, have examined the effect of exercise alone on microvascular complication risk, however given that exercise improves HBA1c and blood pressure, which are two important risk factors for microvascular complication in type 2 diabetes, regular exercise is likely to reduce risk. Cohort studies have shown that greater levels of physical activity and higher cardiorespiratory fitness levels in people with type 2 diabetes are associated with reduced development and progression of retinopathy and nephropathy (Estacio et al., 1998; Holt et al., 2017; Lazarevic et al., 2007; Stratton et al., 2001; John et al., 1994).
