Hypotension has no subjective symptoms, and many people are unaware of it. For others, it can even cause uncomfortable symptoms that interfere with daily life and activities. If hypotension is suspected, it is important to seek diagnosis and treatment. Proper diagnosis and treatment can help prevent falls and other complications. Fortunately, this condition is often treatable, and your doctor can explain many things to help you take care of yourself. Orthostatic hypotension is thought to be an inability of the cardiovascular or nervous system to respond appropriately to sudden changes. When you stand up, blood usually gathers in your lower extremities. If you leave it alone, it will lower your blood pressure. But your body normally sends messages to your heart to speed up your heart rate and constrict your blood vessels, which compensates for the drop in blood pressure. If this does not occur or is too late, orthostatic hypotension can occur and lead to fainting. The risk of both hypotension and hypertension usually increases with age, although this is normal with age. One of the reasons is the change. In addition, blood flow to the heart muscle and brain decreases with age, often as a result of intravascular deposits. It is estimated that 10% to 20% of people over the age of 65 suffer from orthostatic hypotension. Low blood pressure on standing up suddenly can happen to anyone for a variety of reasons. It can also be affected by genetic makeup, aging, medications, dietary and psychological factors, and acute triggers such as infections and allergies. Orthostatic hypotension is most common in people who take drugs to control high blood pressure (high blood pressure). It can also be associated with pregnancy, strong emotions, arteriosclerosis (atherosclerosis), or diabetes. Older people are particularly affected, especially those with hypertension and autonomic nervous system dysfunction. Postprandial hypotension is a common cause of postprandial dizziness and falls. This is most commonly seen after a large, high-carbohydrate meal. It is thought to be caused by blood pooling in the blood vessels of the stomach and intestines. Low blood pressure (hypotension) is low blood pressure that causes symptoms and signs because blood flow through arteries and veins is reduced. When blood flow is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys, the organs cannot function properly, causing temporary or permanent damage. It can be damaged. Changing from sitting or lying to standing often leads to symptoms of hypotension. This happens because standing causes blood to "settle" in the veins of your lower body, lowering your blood pressure. If blood pressure is already low, standing can worsen low blood pressure and cause symptoms. Orthostatic hypotension refers to a drop in blood pressure that causes symptoms such as lightheadedness, lightheadedness, and lightheadedness on standing up. A normal person can quickly compensate for the low pressure generated by standing in the aforementioned response and does not develop orthostatic hypotension. Moderate or severe bleeding can quickly deplete blood cells and cause hypotension or orthostatic hypotension. Bleeding can result from trauma, surgical complications, or gastrointestinal abnormalities such as ulcers, tumors, and diverticulosis.
