Type 2 Diabetes – Raised Blood Pressure on Awakening Raises the Risk of Heart Attack and Stroke


High blood pressure or hypertension upon awakening is dangerous, raising the risk of heart attacks and strokes. Researchers at Tsukuba University in Tokyo, Japan, compared morning hypertension in obese individuals, people diagnosed with Type 2 diabetes, and normal weight individuals without this form of diabetes.

Their study, reported on in the Life Science in April 2014, included 2554 participants with hypertension. Morning blood pressures were …

  • higher in diabetic individuals than in those diagnosed with prediabetes, and
  • lowest in individuals with normal sugar or glucose tolerance.

Among the participants …

  • who registered with normal glucose tolerance, 53.4 percent had hypertension upon waking.
  • prediabetics had a 55.6 percent prevalence of morning hypertension, and
  • among diabetics, 66.4 percent showed morning hypertension.

Obese diabetic patients averaged morning blood pressures of 138.8, while non-obese, non-diabetic patients average 133.1. Among …

  • obese diabetic patients 73.0 percent had morning hypertension, versus
  • 49.9 percent of non-obese, non-diabetic patients.

The causes of hypertension in obesity and Type 2 diabetes are not fully understood, but several molecules are apparently involved. When metabolism is altered among some normal molecules, blood vessels can become stiff and noncompliant, so then the heart must struggle to push the blood through the arteries to the rest of the body. When that happens blood pressure goes up and heart attacks and strokes can result.

The good news is the number of heart attacks and strokes is declining among Type 2 diabetics, due to better control of the condition. According to the Centers for Disease Control and Prevention in Atlanta, United States, from 1990 to 2010 the rate of heart attacks among diabetics in the United States fell 68 percent. The rate of strokes fell by more than 50 percent. This shows what good control can do.

The best way to control Type 2 diabetes is by diet and exercise. Insulin is necessary when diet and exercise are not enough, but the trouble with insulin is that it is a key hormone in the aging process. This is likely one reason why thin people tend to live longer than overweight and obese individuals. And when we slow down the aging process we naturally feel more energetic and appear healthier for a longer period of time.

Eating a diet low in refined sugars and high in fiber helps to control blood sugar levels naturally by …

  • lowering the amount of sugar taken in,
  • by slowing the absorption of sugar, and
  • by lowering body weight.

Walking or other aerobic exercise also helps to control blood sugar levels by increasing sensitivity to insulin and by burning calories, again lowering body weight.
