Then sending hypertension and essential hypertension _ general knowledge

Then sending hypertension and essential hypertension _ general knowledge
1. Nearly there are 10% in hypertension Then sending hypertension (also call symptom hypertension) that the above is . What is called then sending hypertension, then, the reason hypertension takes place is " having good grounds " ,A more outstanding symptom that it is only it that blood pressure increases. Here piece "have according to " Namely the reason of hypertension takes place, it is other diseases in the body, but if we do not trace carefully, this one on " Hypertension " Behavior last one both cause of disease and symptom,it is trace to its source to neglect. In this way, apt to can find, cause precise reason of hypertension some, the ones that can be treated at the same time then sending hypertension is missed, certainly, it is unfavorable to the patient's health. Then, what most easy to cause continuing taking place hypertension disease in the body?

Kidney trouble: Including urgent, chronic glomerulus nephritis, toxaemias of pregnancy, chronic pyelonephritis (influence until renal function in later period) , the renal artery is narrow, kidney stone, kidney tumour,etc., this kind of kidney hypertension is continued and seen in taking place hypertension more most.

Endocrine disease: If renal gland the intersection of cortex and the intersection of function and hyperfunction primary aldosterone increase disease and have a liking for the intersection of chromium and the intersection of cell and tumour,etc..

Vascular disease: The aorta is narrow, occuring frequently big arteritis,etc.. Cranium the intersection of brain and pathological change make in the cranium pigeonholing, increasing, causing symptom nature hypertension.

Then sending essential hypertension, though it is easy to obscure with the essential hypertension, but so long as the patient can provide the whole story having illness coming on for doctor detailedly accurately, the doctor is according to relevant inspections, many reasons can be investigated, and can get the effective treatment too. Such as single side narrow having a liking for the intersection of chromium and the intersection of cell and tumour, the intersection of aorta and narrow, cerebroma,etc. in renal pathological change, renal tumour, renal artery, can carry on the surgery treatment, has removed the cause of disease, " hypertension " Have just improved. Some can't carry on surgery, or need to employ the medicine before surgery, doctors will adopt medicines and step down and treat according to concrete condition, obtain certain curative effect.

Usually essential hypertension which we speak, refer to the essential hypertension, it accounts for the 90% of whole hypertension.

2. What reason cause the essential hypertension? As to this present. It is generally acknowledged, this kind of hypertension is caused by the comprehensive functions of heredity and environmental factor, many scholars think the advanced nervous system function on the cerebral cortex lack proper care, it may be a main pathogenic factor. It is nervous that it is stimulated that external and inherent various are bad, excited, nerve pattern, inherent cause, lacking appropriate rest and sport, taking in too much salt, fat, etc, can cause the control of nervous system and endocrine to lack proper care, make cerebral cortex and easy regulating action of the centre of contracting of lower blood vessel of cortex get muddled, convulsion causing whole body to be arteriolar, the resistance of blood vessel around increases etc. continuously, going down for a long time forms hypertension.

The precise reason for causing the essential hypertension can't be concluded yet, but after the essential hypertension has illness coming on, can cause the pathology damage at various degrees in organs such as arterial system, brain, heart, kidney,etc., the danger of the primary essential hypertension is here mainly too.

Hypertension patient's whole body artery can change certainly, the long-term convulsion especially with arteriolar whole body, may make the intersection of blood vessel and wall take place getting malnutritive to change, inner membrane lay albumen material deposited, fibrous organization increase, China skin layer plump membrane have, the intersection of artery and elasticity lower, in charge of narrowly. Because of the arteriolar change inside, are in charge of increasing and changing narrowly thick, is very like transparent " hyaline " in deposition in ,So call this on medical science " Hyaline to change " . The change of the large and medium-sized artery deposits, becomes narrow, it is on the top to be very like the congee spot piece and stick to, called " The porridge kind changes " . A kind of sclerosis of porridge of arteriolar convulsion and medium-sized artery of brain, will all cause the blood supply of brain to be insufficient, can cause cerebral hemorrhage, cerebral thrombosis and brain softening, a of bleeding under spider's omentum finally.

While suffering from essential hypertension, because of arteriolar convulsion, peripheral resistance of the blood vessel increases, the heart is in order to maintain the unblocked blood circulation, must redouble efforts to shrink, could make the blood up to every place, its result must make the heart too tired, the left ventricle is plump so that expands. Kidney because kidney little arteriosclerosis, form kidney to be ischemic, produce hypertension to be plain finally, impel the arteriolar convulsion of whole body, aggravate hypertension like this, form " vicious circle " . The kidney is ischemic for a long time, the malnutritive change takes place, the renal function will be influenced too.
