What Causes High Blood Pressure?

Causes of high blood pressure... particularly, the essential or benign hypertension... the cause is generally unknown.

Even though the causes of the primary high blood pressure is mostly unknown, but there are risk factors, that may predispose someone to developing this medical condition... these includes...

  • Stress
  • Family history
  • Obesity
  • Age...etc.

In secondary hypertension... the cause is generally known ...because there are primary diseases causing the elevated blood pressure

11 Major Causes of High Blood Pressure


The Secondary Causes of High Blood Pressure includes:

  1. Obstructive sleep apnea..... a sleeping disorder
  2. Pheochromocytoma..... Mainly affects humans around middle age, but can happen anytime. It is a form of tumor that occur in the adrenal gland of the kidneys. It is characterized by the production of too much hormones that elevates the BP
  3. Endocrine disorders...like hypo or hyperthyroidism,(under or overactive thyroid and parathyroid disorders.
  4. An imbalances in kidney functions... including glomerular and blood vessels problems
  5. Medications like... some nasal decongestants, non-steroidal anti-inflammatory drugs, ibuprofen, naproxen...(NSAIDS)
  6. Chronic and  ongoing alcohol abuse.
  7. Genetic narrowing of the largest artery of the body, the aorta... "coarctation of the aorta"
  8. Reno vascular disease:  this affects the arteries supplying nutrients to  the kidneys, because kidneys are not able to function properly, in the process elevating the blood pressure 
  9. Primary aldosteronism : too much aldosterone is produced by the adrenal gland causing retention of sodium and loss of potassium and in the process causing hypertension
  10. Prolonged oral contraceptives in sensitive individuals

11  Cushing syndrome:  a condition in which there is too much cortisol in the body, either by too much production, or through oral intake thereby increasing the BP

Pathophysiology of Hypertension

Pathophysiology of hypertension and etiology refers to the study of the causes of high blood pressure.
