A recent study has found a found an association between PTSD severity and health risk as measured by metabolic syndrome (systolic and diastolic blood pressure, waist-to-hip ratio and fasting measures of high-density lipoprotein (HDL) cholesterol, serum triglycerides and plasma glucose concentration), an important established predictor of morbidity and mortality. It is therefore quite possible that severe PTSD can result in significant health problems.
