symptoms of hypertension

Mild to moderate primary (essential) hypertension has no symptoms for many years, so the typical patient has no reason to be aware of having hypertension. The most frequent symptom of hypertension, headache, is also very nonspecific. Suboccipital pulsating headaches, characteristically occurring early in the morning and subsiding during the day, are said to be characteristic, but any type of headache may occur. Accelerated hypertension is associated with somnolence, confusion, visual disturbances, and nausea and vomiting (hypertensive encephalopathy).
Patients with pheochromocytomas that secrete predominantly norepinephrine usually have sustained hypertension but may have episodic hypertension. Attacks (lasting minutes to hours) of anxiety, palpitation, profuse perspiration, pallor, tremor, and nausea and vomiting occur; blood pressure is markedly elevated, and angina or acute pulmonary edema may occur. In primary aldosteronism, patients may have muscular weakness, polyuria, and nocturia due to hypokalemia; malignant hypertension is rare. Chronic hypertension often leads to left ventricular hypertrophy, which may be associated with diastolic or, in late stages, systolic dysfunction. Exertional and paroxysmal nocturnal dyspnea is an important symptom of hypertension, and ischemic heart disease is more common symptom of hypertension (especially when concomitant coronary artery disease is present).Cerebral involvement causes(1) stroke due to thrombosis or (2) small or large hemorrhage from microaneurysms of small penetrating intracranial arteries, and focal symptoms depend upon which vessels are involved. Hypertensive encephalopathy is probably caused by acute capillary congestion and exudation with cerebral edema. The findings are usually reversible if adequate treatment is given promptly. There is no strict correlation of diastolic blood pressure with hypertensive encephalopathy; it usually exceeds 130 mm Hg.
in that article i covered common symptoms of hypertension to be easy for you to take care about your self and discover that wide soread disease early.
