Substances that Affect Hypertension

Nicotine

Smoking increases stress on the heart and arteries, which increases the risk of strokes and cardiac events. It also raises blood pressure by increasing the levels of adrenaline in the blood, thus constricting the vessels.

A disaster triangle is formed when people with hypertension and high cholesterol opt to smoke.

After smoking only two cigarettes, both systolic and diastolic pressures increase temporarily by an average of 10mmHg each. If you smoke heavily, your blood pressure is increased throughout the day.

Smoking interferes with some blood pressure medications.

Alcohol

Drinking too much can increase your blood pressure and interfere with your medication.

How much is too much? Some research indicates, that even two drinks a day raise blood pressure. One drink per day should be the limit for hypertensives. Alcohol is also rich in calories, thus contributing to overweight, which is a risk factor for hypertension.

Experts estimate, that about 10 percent of hypertension cases are due to excessive alcohol consumption.

Caffeine

Caffeine is a stimulant which may increase your blood pressure. 2-3 cups of coffee may raise both systolic and diastolic BP by 3-14 mm Hg. The effect is often more pronounced in people who are NOT regular coffee drinkers.

Caffeine is also found in tea, Coca-Cola and chocolate.

Drugs

Many drugs, whether illicit drugs like ecstasy or cocaine, or over-the-counter drugs such as anti-inflammatory medication, can raise your blood pressure.
