Definition of hypertension or high blood pressure a disturbance in the circulatory system that can cause blood pressure increases above the normal value, which exceeds 140/90 mmHg. Hypertension in the English language is Hypertension, Hypertension derived from two words meaning the Hyper high, and the mean voltage Tension.
When the examination of blood pressure resulted in two points, namely a higher rate and a lower number. Higher figure obtained when the heart contracts (systolic), while the lower figure is obtained when jantuk relaxes (diastolic). Blood pressure less than 120/80 mmHg can be interpreted as a normal blood pressure. When there is high blood pressure, is generally an increase in systolic and diastolic pressures. Hypertension usually occurs when blood pressure reaches 140/90 mmHg or more, blood pressure measurement is performed on the arm three times in a few weeks.
symptoms of Hypertension
Hypertension or high blood pressure should watch out, because usually in people with hypertension do not feel any symptoms. but accidentally some symptoms occur simultaneously and reliably associated with high blood pressure (but not really). Symptom in question is a headache, bleeding from the nose, dizziness, flushed face and fatigue, which could have occurred either in patients with hypertension, as well as to a person with normal blood pressure.
If hypertension is at the level of severe or chronic and untreated, symptoms can include: headache, fatigue
nausea, vomiting, shortness of breath, anxiety, blurred vision that occurs because of damage to the brain, eyes, heart and kidneys. Sometimes patients with severe hypertension decreased consciousness and even coma due to brain swelling. This situation is called hypertensive encephalopathy, which should immediately get treatment.
The cause of hypertension
Based on the cause, hypertension consists of two kinds of Hipetensi Primary or Essential Hypertension and Secondary.
A primary or essential hypertension or hypertension that is not yet known why the (present in approximately 90% of all hypertension).
Secondary hypertension is hypertension caused by / as a result of the presence of other diseases.
Primary hypertension is likely to have many causes, some of the changes on the heart and blood vessels together likely cause increased blood pressure.
If the cause is unknown, it is called secondary hypertension. In about 5-10% of patients with hypertension, the cause was kidney disease. In about 1-2%, the cause is a hormonal disorder or the use of certain medications (eg birth control pills).
Other rare causes of hypertension are pheochromocytoma, the tumors in the adrenal gland that produces hormones epinephrine (adrenaline) or norepinephrine (noradrenaline).
Overweight (obesity), an inactive lifestyle (exercise lazy), stress, alcohol or salt in food, can lead to hypertension in people who have reduced sensitivity. Stress tends to cause rise in blood pressure for a while, if the stress has passed, the blood pressure usually returns to normal.
Some causes of secondary hypertension include:
Renal disease: Renal artery stenosis, pyelonephritis, glomerulonephritis, kidney tumors, kidney disease polikista (usually inherited), Trauma to the kidneys (the kidney injury), Radiation therapy of the kidney.
Hormonal Disorders: Hyperaldosteronism, Cushing syndrome, Phaeochromocytoma, Drugs: Birth control pills, corticosteroids, Cyclosporine, Erythropoietin, Cocaine, Alcohol abuse, Cinnamon (in very large amounts)
Other Causes: aortic coarctation, Preeclampsia in pregnancy, acute intermittent Porphyria, acute lead poisoning.
Food Lowering High Blood Pressure
There are several natural makana that can lower high blood pressure include: Spinach, Sunflower Seed, Nuts, Bananas, Soybeans, Potatoes, Avocado, Dark Chocolate, Mentimum, Melon, Watermelon.
Hopefully the article that discussed the definition of hypertension, symptoms of hypertension, the cause of hypertension, type of hypertension and hypertension-lowering diet above could increase your knowledge in the field of health. And may you and the people you love are not easily affected by hypertension or high blood pressure.
