Causes of Hypertension

There are two types of hypertension: primary of essential hypertension and secondary hypertension.

For the majority of adults, there is no recognizable cause of high blood pressure. This type of high blood pressure has a tendency to develop progressively over several years.

Several people have hypertension caused by an underlying condition. This type of hypertension is likely to appear suddenly and lead to a higher blood pressure compared to primary hypertension, like:

  • Kidney problems
  • Thyroid problems
  • Congenital defects in blood vessels
  • Obstructive sleep apnea
  • Adrenal gland tumors
  • Certain medications
  • Illegal drugs
  • Alcohol abuse
