High diastolic blood pressure - the problem is serious

High diastolic blood pressure - the problem is serious
How to lower

High diastolic blood pressure High diastolic blood pressure is more common in young patients, and is the result of some other disease (kidney, adrenal, thyroid, pituitary, and so on). In young and middle age can develop essential hypertension, in which the only symptom is a high blood pressure.

What does a high diastolic pressure

Blood pressure is determined by two numbers: the systolic performance of the upper or lower pressure and diastolic. Systolic blood pressure depends largely on the volume of blood which the heart ejects during compression (systole) in blood vessels. Diastolic - a pressure exerted on them by the moving blood blood vessels during diastole (relaxation of the heart muscle).

Both of these indicators are important. The upper, or systolic often called the "heart" pressure as when increasing development of various cardiac disorders. A diastolic pressure is considered to be "kidney", since most often develops in the kidney. But the increase in diastolic pressure may be in essential hypertension.

Hypertension with high diastolic pressure Diastolic blood pressure is an important indicator of health more common in young and middle-aged, while isolated systolic hypertension is more prevalent in older people.

Why is the diastolic pressure rises

Diastolic blood pressure is often elevated in diseases of certain organs, ie, hypertension in this case is not an independent disease, but a symptom of some other disease (symptomatic hypertension). Diseases with high diastolic blood pressure - is, above all, kidney, adrenal, pituitary and thyroid glands.

Kidney diseases that contribute to the narrowing of the arteries supplying the kidneys, always accompanied by a rise in diastolic pressure.

With a lack of nutrients and oxygen, that is, fasting, the kidneys begin to release the hormone renin, has a strong vasoconstrictor properties. It contributes to the rise of the renin-diastolic pressure. Very often symptomatic hypertension develops in children with chronic glomerulonephritis - severe infectious and allergic diseases of the kidneys, which often lead to the development of chronic renal failure.

What caused the high diastolic blood pressure in adults? Often the same reasons - chronic glomerulonephritis, which can be up to 20-30 years, proceed unnoticed.

The reason for the high diastolic pressure may lie in the development of hormone adrenal tumors - pheochromocytoma, which can be worn both benign and malignant character. Pheochromocytoma produces the hormone adrenaline adrenal medulla, which is actively narrows blood vessels and raises blood pressure.

Causes of high diastolic blood pressure may be associated with the thyroid gland.

Blood pressure may rise as an increase or decrease in the function of the thyroid gland, but the increase in diastolic blood pressure is more common to lower thyroid function - hypothyroidism.

Reasons essential (not connected with any other disease) hypertension is not well established. Typically, this is a whole range of reasons: poor diet, sedentary lifestyle, overweight, emotional stress, sudden stress, and, most importantly, - family history (the presence of close relatives with the same pathology).

Symptoms of high diastolic blood pressure

High diastolic blood pressure is symptomatic, and hypertensive patients often begins quite discreetly. This is very dangerous, because it leads to the development of complications. For example, high diastolic blood pressure in children suffering from idiopathic form of chronic glomerulonephritis, can long time does not manifest itself. Often only in violation of the first symptoms of kidney disease. High diastolic blood pressure in a child may develop on the background of congenital anomalies of the kidney vessels. In this case it may occur unnoticed until until it has chronic renal failure.

High diastolic blood pressure in the young may also be due to diseases begin in childhood, for example, goes unnoticed chronic glomerulonephritis. Only in 20-30 years this disease can appear in the form of severe renal vascular lesions with decreased kidney function.

High diastolic blood pressure of a woman developing diseases of the thyroid gland - women are more likely to occur. In hypothyroidism Hypothyroidism in some women pressure drops and rises in part with simultaneous rise in diastolic pressure. For a long time this disease can occur unnoticed. Sometimes women suffer from headaches and dizziness, severe dryness occurs throughout the body, hair fall out Hair: structure, characteristics of growth and development . But in general, high blood pressure is most often detected by chance.
