Hypertension, also known as high blood pressure, is when a person’s blood pressure is regularly above 140/90 mmHg. It is also called arterial hypertension. This heightened pressure causes damage to the heart and surrounding arteries. People with high blood pressure are more likely to experience strokes and heart attacks. Symptoms are not apparent in early stages of hypertension, but yearly checks with your doctor will help you avoid the risks associated with high blood pressure. There are two types of hypertension: primary, also known as essential, and secondary. The causes of primary hypertension are unknown, and its onset is sudden. Secondary hypertension can be caused by poor diet, use of drugs, whether prescription or illegal, thyroid issues and other congenital problems. Diet, exercise, and medication can help lower high blood pressure, thus decreasing the likelihood of stroke or heart attack.
