Hypertension is the increased blood pressure on blood vessel. When the heart pumps, blood volume creates pressure on blood vessels (arteries) wall. If blood pressure exits a certain level, hypertension occurs. Generally 140/90 mmHg or above pressure considered as hypertension. It is the major cause of death in every country in the world. According to the World Hypertension League (WHL) 1.5 billion people are affected by hypertension every year, among them seven million are American.
Hypertension are two types according to causes:
Primary cause of hypertension
When the actual cause of hypertension cannot be identified, it is termed as primary hypertension. Sometimes genetic causes relies on primary cause of hypertension. Many normal, healthy individuals have high blood pressure level, although they have no other health complications.
Secondary causes of hypertension
Secondary causes of hypertension are those causes which can be identified. Secondary hypertension is the effect of any other known physical complications. Knowing the secondary cause of hypertension, we may take preventive steps against hypertension. The common causes of secondary hypertension are:
- Obesity: obesity often causes high blood pressure, because obese persons have high blood cholesterol level. Arterial wall become thicker and harder due to deposition of cholesterol that faces high pressure.
Stress: A hormone renin increases blood volume and hypertension occurs. Renin releases from the kidney in mental stress. Stress in a longer period of time cause hypertension.
- Kidney disease: in some kidney diseases Renin releases from the kidney in an uncontrolled manner. Release of excess levels of renin causes hypertension.
Salt consumption: excess amount of salt in diet results high blood volume, therefore high blood pressure.
Birth control pills: taken of birth control pills for prolonged periods, accumulate fats in arteries and hypertension occurs.
Over alcohol intake and smoking.
- Diabetes: diabetes patients often face hypertension.
- Insomnia or sleeping problem often cause hypertension.
- Ageing: when people getting older, they have a higher risk of hypertension.
- Pregnancy: pregnant women become fatty and have a risk of pre-hypertension and hypertension.
- Hyperthyroidism and hypothyroidism, both causes hypertension.
- Genetic factor: hypertension is a most common familial disorder.
- No physical activity: a physically active person has a low chance of hypertension.
- Calcium deficiency.
- Vitamin D deficiency.
To minimize the risk of hypertension you should maintain a reasonable weight. Get balanced diet and should do some exercise regularly.
