Hypertension is generally sub divided into 2 types:
Essential hypertension is the most prevalent hypertension type, affecting 90-95% of hypertensive patients.Although there is no direct cause or mechanism identified some factors are considered to cause Essential Hypertension.
Sedentary Lifestyle Obesity accounts for 80-85% of essential hypertension Increased salt intake Increased youalcohol intake Vitamin D Deficiency Family history of high blood pressure Genetic diseases Renin -a hormone produced by the kidneys is thought to activate sympathetic system which functions to control most of body' internal organs under different conditions. High fructose (sugar)corn syrup Metabolic syndrome -in which body develops insulin resistance due to obesity and has high blood pressure, sugar,cholesterol and increased waist circumference.
Secondary hypertension by definition results from an identifiable cause. This type is important to recognize since it's treated differently than essential hypertension, by treating the underlying cause of the elevated blood pressure. Hypertension results compromise or imbalance of the pathophysiological mechanisms, such as the hormone-regulating endocrine system, that regulate blood plasma volume and heart function. Many conditions cause hypertension, some are common and well recognized secondary causes such as
Renovascular Hypertension: Due to fibromuscular dysplasia and renal artery stenosis. In both conditiions, increased blood pressure occurs due to narrowing of arteries supplying to the kidney. Pheochromocytoma: Caused by an excessive secretion of norepinephrine and epinephrine which promotes vasoconstriction Hyperaldosteronism (Conn's syndrome): Idiopathic hyperaldosteronism, Liddle's syndrome (also called pseudoaldosteronism), glucocorticoid remediable aldosteronism Cushing's syndrome - an excessive secretion of glucocorticoids causes the hypertension Hyperparathyroidism Acromegaly Hyperthyroidism Hypothyroidism Chronic Kidney disease Coarctation of Aorta Drugs: Oral Contraceptives, steroids, NSAIDs, nasal decongestants with adrenergic effects, MAOIs, adrenoceptor stimulants. Scleroderma Neurofibromatosis Pregnancy -unclear mechanism Obstructive sleep apnea Fever: unclear etiology Liquorice White coat hypertension: that is, elevated blood pressure in a clinical setting but not in other settings, probably due to the anxiety some people experience during a clinic visit. Perioperative hypertension is development of hypertension just before, during or after surgery. It may occur before surgery during the induction of anesthesia; intraoperatively e.g. by pain-induced sympathetic nervous system stimulation; in the early postanesthesia period, e.g. by pain-induced sympathetic stimulation, hypothermia, hypoxia, or hypervolemia from excessive intraoperative fluid therapy; and in the 24 to 48 hours after the postoperativ period as fluid is mobilized from the extravascular space. In addition, hypertension may develop perioperatively because of discontinuation of long-term antihypertensive medication.
