High blood pressure (hypertension) is defined as high pressure (tension) in the arteries, which are the vessels that carry blood from the heart to the rest of the body. Complications of high blood pressure include heart disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage).
There are two types of Hypertension:
- Primary Hypertension
- Secondary Hypertension
You are said to have primary hypertension, when there are no identifiable causes of high blood pressure. It is also called essential hypertension which tends to develop gradually over many years.
Primary Hypertension accounts for 90-95% of all cases of Hypertension. When your hypertension is caused by an underlying medical condition, it is called secondary hypertension. It tends to appear suddenly. The medical conditions can be:
- Kidney problems
- Atherosclerosis (hardening of arteries)
- Adrenal gland tumors
- Thyroid problems
- Obstructive Sleep Apnea
- Pregnancy (known as gestational hypertension)
- Anxiety or stress
- Cushing’s syndrome
