Both type 2 diabetes and high blood pressure (hypertension) share common risk factors such as obesity, an unhealthy diet, and physical inactivity.

It is therefore not surprising that people with type 2 diabetes have a higher chance of developing high blood pressure.

In addition, uncontrolled diabetes causes narrowing of the blood vessels (atherosclerosis) which in turn can lead to high blood pressure. 

Having both high blood pressure and diabetes greatly increases your risks of having a heart attack, stroke, diabetic eye disease and kidney disease. So do your best to keep your blood pressure within the normal range to prevent these diseases.
