Sometimes doctors encounter young women whose reason for visit is dizziness, or weakness. Most of these patients are thin and weak. In addition to the usual dizziness and weakness, some of them feel tired and weak in the morning when they wake up, and the symptoms of dizziness appear or worsen when they change their position from lying to sitting or standing. Others were drowsy after lunch and could not concentrate mentally. Systematic examination did not reveal any abnormalities, such as anemia and endocrine system disorders. The only abnormality was a lower than normal blood pressure. This is typical of a young female hypotensive patient. The onset and management of hypotension in young women has its own characteristics compared to other hypotension. What is hypotension? Hypotension is defined as a blood pressure of less than 90 mmHg systolic and 60 mmHg diastolic, whether due to physiological or pathological causes. Hypotension can be divided into acute hypotension and chronic hypotension. For example, a decrease in blood pressure resulting from massive blood loss is acute hypotension. What we usually call hypotension refers to chronic hypotension. There are different ways to classify chronic hypotension. Generally, it can be divided into three categories: Somatic hypotension: related to genetics and lean body mass, mostly seen in women aged 20-50 years old and the elderly, the milder cases can be without how symptoms, the more severe cases appear mental fatigue, dizziness, headache, and even fainting. In summer, when the temperature is high, some women with poor health usually feel weak and dizzy, and some of them are caused by low blood pressure. This is because the blood vessels are dilated at this time, making the decrease in blood pressure more pronounced. Postural hypotension: Postural hypotension is a sudden drop in blood pressure of more than 20 mmHg when the patient goes from a recumbent to a sitting or upright position, or when standing for a long time, and is accompanied by significant symptoms, which include: dizziness, lightheadedness, blurred vision, weakness, nausea, cognitive dysfunction, palpitations, neck and back pain, and even fainting in severe cases. Postural hypotension is associated with a variety of diseases, such as multisystem atrophy, diabetes, Parkinson’s disease, multiple sclerosis, menopausal disorders, hemodialysis, post-surgical sequelae, anesthesia, antihypertensive drugs, diuretics, hypnotics, anti-psychotic depressants, etc. It also occurs in bedridden and frail elderly people. Secondary hypotension: Hypotension caused by certain diseases or drugs, such as spinal cavernous disease, rheumatic heart disease, antihypertensive drugs, antidepressants and chronic malnutrition, hemodialysis patients. The causes vary from person to person. For example, hypotension in rheumatic heart disease is associated with reduced blood displacement; those on antihypertensive medications are associated with a transitional reduction in blood pressure; hemodialysis patients are associated with too much reduction in blood volume, and so on. These three types of chronic hypotension can be intertwined and exist together. For example, hypotension in young women is mostly somatic hypotension, combined with postural hypotension if postural changes aggravate the symptoms, and may also be associated with secondary hypotension if rheumatic heart disease is present. Given that the above classification does not emphasize whether the pathogenesis of hypotension is “diseased” or “non-diseased”, a better classification that is valuable in guiding the disease is to divide hypotension into two categories: physiologic hypotension and pathologic hypotension. In physiological hypotension, no serious diseases are found on physical examination and long-term follow-up. There are no abnormalities in the body systems and organs, such as ischemia and hypoxia, and life expectancy is not affected. Physiologic hypotension is seen in young women, especially those with long and lean bodies, and also in those who exercise a lot and who are heavy workers. These patients are collectively referred to as young women with hypotension. The development of hypotension in these individuals is often associated with high vagal tone. The prognosis for physiological hypotension in young women is good, and, because of the lighter cardiovascular load, the circulatory organs may age later than in those with normal blood pressure and are more likely to live longer. Young women in the state of physiological hypotension do not need to worry about low blood pressure, nor do they need to seek medical help to restore blood pressure to normal, and they should not blindly seek help from street doctors because they cannot find a remedy to raise blood pressure in regular hospitals. Patients with physiological hypotension do not need medication if they do not have any symptoms. If there is obvious dizziness and weakness, you can take measures to actively participate in physical exercise to improve physical fitness, and properly increase nutrition, drink more water, eat more soup, and eat slightly more salt than normal people every day. Regular use of Chinese herbal medicine Astragalus, princely ginseng, jujube and white lentils also have considerable curative effect. Water with American ginseng can regulate blood pressure in both directions and increase water intake. Pathological hypotension refers to a disease that causes it. In addition to lower than normal arterial blood pressure, these patients often have general weakness, dizziness, easy fatigue, sweating, palpitations and other symptoms, when standing for a long time or from lying (or sitting, squatting) to standing, the above symptoms are more obvious, and even fainting. Chronic hypotension can have a genetic predisposition and can also be secondary to certain neurological diseases, cardiovascular diseases, chronic malnutrition, endocrine dysfunction, recovery from infectious diseases, and the use of certain antihypertensive drugs, often accompanied by corresponding discomfort and examination abnormalities. Treatment of pathological hypotension focuses on the treatment of the primary cause. For example, cardiac insufficiency should improve cardiac contractility and rational application of diuretics. Transitional diuresis is also a cause of hypotension. The most common cause of pathological hypotension in young women is endocrine disorders. Only when the endocrine disease is controlled, it is possible to restore the excessively low blood pressure to normal. Therefore, young women with hypotension accompanied by signs and symptoms such as amenorrhea, loss of libido, hair loss and hyperpigmentation must visit a specialist to detect the cause and take correct treatment measures as soon as possible.
