Hypotension is generally defined as blood pressure below 90/60 mmHg, but in patients with hypertension, especially those who have developed cardiac, cerebral, and renal complications, clinical symptoms associated with low blood pressure can occur before the blood pressure reaches this level. While high blood pressure is harmful, low blood pressure can also have adverse effects on the body. Hypotension is most common in growing adolescents, the frail, and the elderly, and its dangers and principles of management vary from person to person: Patients with hypertension on medication Patients with hypertension who develop symptoms of low blood pressure or suspected hypotension (dizziness, headache, blackness, syncope, etc.) while on antihypertensive medication should promptly see a physician to adjust their treatment plan and reduce the type of medication or the dose of medication, as appropriate. The dose of medication should be reduced as appropriate. Postural hypotension: When the body position changes, such as squatting and standing, or standing for a long time, the symptoms of blackness and dizziness may occur due to insufficient blood supply to the head. There are two main reasons for this type of hypotension: first, most elderly people have atherosclerotic lesions, resulting in a decrease in the body’s ability to regulate blood pressure; second, some elderly patients with hypertension are caused by improper use of antihypertensive drugs. Elderly people suffering from postural hypotension are prone to sudden falls and fractures, or even accidental death. Severe hypotension can also increase the risk of cerebral infarction and myocardial ischemia. Weakness causes hypotension Weak people, teenagers, those who lack exercise and women have more chances of hypotension, some without any symptoms and some may experience dizziness, weakness, shortness of breath, mental weakness and easy fatigue. Some girls go on excessive diet or have an unreasonable diet structure in order to slim down, which leads to insufficient supply of nutrients in the body and produces symptoms of hypotension. Seasonal hypotension is more common in the hot summer, due to excessive sweating resulting in reduced blood volume, coupled with vasodilatation and can result in lower blood pressure, patients may have temporary headache, dizziness, chest tightness, shortness of breath and other symptoms. Hypotension generally does not require drug treatment, but rather prevention. The first step is to strengthen exercise and physical fitness. Both young people and the elderly should adhere to physical exercise every day, if it is difficult to tolerate strenuous activities, you can choose some less intense exercise, such as walking, bicycling, swimming, tai chi, square dance, etc.; secondly, we should eat reasonably and strengthen nutrition. In the life of a reasonable mix of meals, not partial diet, to ensure the intake of a comprehensive and adequate nutrients. Summer is the high season of low blood pressure, people with low blood pressure should pay attention to drink more water, replenish blood volume, and eat more food with high salt content appropriately to prevent excessive drop in blood pressure. The elderly should pay special attention to the prevention of postural hypotension. Patients with hypertension must take antihypertensive drugs under the guidance of a doctor and not change the type and dose of antihypertensive drugs at will; usually pay attention to the speed when changing positions, for example, do not get up too quickly when getting up or rising from a sitting position. If your symptoms are not relieved for a long time, you should go to the hospital for timely treatment. How can I stabilize my blood pressure? 1.Adhere to monitoring blood pressure. 2.Drink more water to prevent dehydration. 3.Pay attention to cooling down and avoiding heat. 4.Adjust the amount of medication according to the blood pressure. Generally speaking, if your blood pressure does not drop excessively, you should continue to take your medication at the same dose. Some people’s blood pressure is obviously low in the summer, when still taking the winter dose is easy to make the blood pressure drop too low, so it is easy to appear such as dizziness, lack of blood supply to the brain, weakness or even lead to cerebral infarction or angina attack. The doctor will adjust the dose according to the patient’s monitoring results. But patients should never change their medication at will. 5, the elderly should not be excessive pressure lowering. 60 years old and above, all have varying degrees of atherosclerosis, so a higher blood pressure is conducive to the blood supply of the heart, brain, kidneys and other organs. 6, life therapy should not be relaxed. If you have developed good habits to prevent and control hypertension, do not abandon them because your blood pressure has dropped in the summer. You should adhere to the scientific arrangement of 24 hours a day life, eliminate risk factors and maintain good health care habits.
