Diabetes, as one may argue, is probably the worst human disease because of its slow, but relentless damage of multiple organs systems. Hypertension on the other hand is a ‘Silent killer’ causing major risk of adverse cardiac and brain events without producing clinical symptoms. High blood pressure multiplies the troubles significantly in diabetic patients.
Is diabetes and hypertension inter-related?
Diabetes and high blood pressure often coexist. More than half of diabetics have high blood pressure. Whether it is occurrence of two different diseases at same time or manifestation of some common underlying metabolic disorder is a matter of speculation. However, some researchers now believe that the co-occurrence of these disease is more than chance. Certain genetic or environmental factors may be responsible for causing both the diseases.
What are the problems of having diabetes and hypertension together?
The presence of high blood pressure in patients with diabetes mellitus greatly increases the risk of myocardial infarctions or heart attack, stroke, and an early likelihood of dying from all causes. As both the conditions cause damage to small blood vessels like those in eye, kidneys, heart and brain, these patients also have higher chances of complications like retinopathy, vision loss, and kidney dysfunction.
Hypertension and diabetes have another common friend, called obesity. All these three are closely linked to each other and may also possibly have a common etiologic origin. Obesity also puts enormous stress on the organ systems and increase the risk burdens for cardiovascular and stroke events.
How should we tackle this combination of problems?
When a patient has both diabetes and hypertension, a combination of lifestyle modification and medication is required. All the problems need to be tackled simultaneously, as controlling only one may not translate into satisfactory overall results.
Lifestyle modification includes a shift towards healthy balanced diet and physical activity during daily routine like use of stairs instead of elevators, walking or cycling instead of driving.
American Heart Association(AHA) recommends at least 150 minutes of moderately intense aerobic activity like brisk walking per week or 75 minutes of vigorous aerobic activity like running or aerobic dancing per week.
Weight loss in obese patients helps in improving both sugar control and high blood pressure. Regular exercise, diet, limitation on extra calories and restriction of carbohydrates help achieve a 3-5% weight loss, which is considered sustainable.
Regular visits to your doctor is must to keep blood sugars and high blood pressures under good control. Glycosylated haemoglobin or HbA1c levels are used as a reference to index quality of control in diabetics. It tells about the average blood sugar levels over the last three months and a value of less than 6.5% is considered very good control, even though levels <7.0% are considered good control to reduce complications.
What should my blood pressure be if i have Diabetes?
For blood pressure in patients with diabetes, the target is below 140/90mmHg. 140 is the systolic blood pressure and 90 mmHg is the diastolic blood pressure.  For younger patients a more aggressive target is 130/80mmHg. Having a blood pressure below these levels goes a long way in reducing the complications associated with diabetes and hypertension. Increased physical activity helps in improving blood vessel contractility and overall cardiac health. Weight loss and medications further help in improving control of high blood pressure.
Patients with diabetes should get their blood pressures monitored regularly, at least a couple of times every month and visit a physician regularly.
