High levels of blood sugar, if not checked in time, can lead to a range of metabolic disorders including type 2 diabetes. Continuously high levels of sugar circulating in the blood can trigger oxidative stress and inflammation in the blood vessels. This creates serious complications in the vascular system, making diabetic patients particularly vulnerable to cardiovascular problems (increased blood pressure, cholesterol levels, triglyceride levels, heart failure and stroke), kidney damage, impaired or complete loss of vision (diabetic retinopathy), nerve damage and even depression and dementia.
