Causes of the hypertensive crisis
The most common cause of the hypertensive crisis is non-compliance with medications in chronic hypertensive patients, which causes an unexpected elevation of blood pressure.
Other common causes of the hypertensive crisis include:
- Heart attack
- Heart failure
- Renal failure
- Preeclampsia and eclampsia in pregnant females
- Adrenal gland tumors (pheochromocytoma) that increase the secretion of catecholamines (adrenaline and noradrenaline), which are blood pressure-raising substances.
- Thyroid gland diseases (Hyperthyroidism and hypothyroidism)
- Alcohol withdrawal and withdrawal of other drugs, like beta-blockers (atenolol)
- African-American people and older people have a high risk of hypertensive crisis.
- Stimulant-drugs toxicity like cocaine and amphetamine
- Psychological stress in chronic hypertension patients
- Physiological stress that occurs during and after some surgical operations like cardiothoracic and neurosurgical operations
All of these causes can lead to a hypertensive crisis. Thus, any patient with any of these conditions should check their blood pressure continuously and follow their doctors’ advice to keep their blood pressure away from dangerous levels. Also, chronic hypertensive patients should take all doses of their medications and try not to miss any of them.
