Symptoms of hypotension

summary

Hypotension is a condition in which the arterial pressure of systemic circulation is lower than normal. Because hypertension often causes damage to heart, brain, kidney and other important organs in clinic, it has been paid much attention. The World Health Organization has also clearly defined the diagnostic criteria for hypertension, but there is no unified standard for the diagnosis of hypotension. It is generally believed that hypotension is defined as lower than 12 / 8 kPa (90 / 60 mmHg) in adults. According to the etiology, it can be divided into physiological and pathological hypotension, and according to the form of onset, it can be divided into acute and chronic hypotension. Symptoms of hypotension? Let's talk about it

Symptoms of hypotension

Acute hypotension refers to patients with blood pressure from normal or higher levels of sudden and significant decline, clinical often due to brain, heart, kidney and other important organs ischemia, dizziness, dark eyes, soft limbs, cold sweat, palpitation, oliguria and other symptoms, severe performance for syncope or shock.

Constitutional hypotension is generally considered to be related to heredity and physical weakness. It is more common in women and the elderly aged 20-50 years old. Mild hypotension may have no symptoms, while severe hypotension may have mental fatigue, dizziness, headache or even fainting. It is more obvious when the temperature is higher in summer.

Postural hypotension is related to postural changes (especially upright position) in some patients, which is called postural hypotension. Postural hypotension is defined as: systolic blood pressure drop > 20mmhg or diastolic blood pressure drop > 10mmhg within 3 minutes of changing postural to upright position, accompanied by hypoperfusion symptoms, including: dizziness, dizziness, blurred vision, fatigue, nausea, cognitive dysfunction, palpitation, neck and back pain. Elderly patients with isolated systolic hypertension, diabetes mellitus and hypovolemia are prone to orthostatic hypotension by diuretics, vasodilators or psychotropic drugs.

matters needing attention

Life should be regular, to prevent excessive fatigue, because extreme fatigue will lower blood pressure. To maintain a good mental state, appropriately strengthen exercise, improve physical fitness, improve the regulatory function of nerves and blood vessels, accelerate blood circulation, reduce the attack of orthostatic hypotension, the elderly exercise should choose sports according to the environmental conditions and their own physical conditions, such as Taijiquan, walking, aerobics and so on.
