Hypotension
Manifestations of low blood pressure
Low blood pressure refers to a phenomenon where the systolic blood pressure is below 90mmHg and/or diastolic blood pressure is below 60mmHg. After developing low blood pressure, symptoms such as dizziness, palpitations, fatigue, and cold sweats often occur. If you have low blood pressure, it is essential to visit a hospital for proper examinations, such as a blood test to check for anemia. Conducting an echocardiography or an electrocardiogram can help determine if any heart diseases are causing the low blood pressure.
What blood pressure is considered low blood pressure?
Systolic pressure less than 90 mmHg and diastolic pressure less than 60 mmHg indicate low blood pressure. The normal blood pressure range for adult males and females of any age is a systolic pressure between 90 to 139 mmHg and/or diastolic pressure between 60 to 89 mmHg. High blood pressure is defined as having a systolic pressure of 140 mmHg or higher and/or a diastolic pressure of 90 mmHg or higher. Arterial blood pressure varies among individuals, as well as by age and gender, with a general trend of increasing pressure as age advances, and the increase in systolic pressure is more pronounced than that in diastolic pressure. Before menopause, women tend to have slightly lower blood pressure than men of the same age, but after menopause, their blood pressure generally aligns with or even slightly exceeds that of their male counterparts.
Can people with low blood pressure drink tea?
People with low blood pressure can drink tea. Currently, there are many types of tea in daily life: green tea, oolong tea, black tea, Tieguanyin, as well as some medicinal teas such as ginseng tea, astragalus tea, and goji berry tea. Regular consumption of these teas is beneficial for health, as they provide essential nutrients. The active ingredients in tea can enhance mental alertness, promote blood circulation, and increase heart vitality. Additionally, some medicinal teas like astragalus tea and goji berry tea have the effects of replenishing qi, nourishing yin, and supporting kidney health. By nourishing yin and supporting kidneys, and adjusting the blood through replenishing qi, these teas can help raise blood pressure.
Clinical symptoms of low blood pressure
The clinical symptoms of hypotension mainly depend on its type. For example, in patients with orthostatic hypotension, symptoms such as dizziness, syncope, or even falling may occur when moving from a lying to a standing position. For hypotension caused by shock, it can be divided into hypovolemic shock and shock caused by reduced cardiac output, which may lead to symptoms like reduced urine output, cold and clammy skin, rapid heart rate, and short pulse. The clinical symptoms caused by cardiac tamponade are also generally related to reduced cardiac output. If the hypotension is caused by gastrointestinal bleeding, symptoms like vomiting blood and black stools may occur. Thus, the symptoms of hypotension can vary greatly depending on the cause.
Rescue of hypotensive shock
Low blood pressure is an important clinical symptom and diagnostic indicator of shock. Regardless of what causes the shock, the presence of low blood pressure, along with cold limbs, cold sweat, reduced urine output, and an indifferent expression, indicates insufficient peripheral vascular perfusion. Prolonged insufficient perfusion can lead to damage to vital organs. Therefore, timely emergency treatment is essential to elevate blood pressure and save the patient's life. The initial steps include administering oxygen to ensure the oxygenation of vital organs, replenishing blood volume, using vasopressors, and providing timely emergency treatment to save the patient's life.
What is the range for low blood pressure?
Blood pressure is an important indicator of human vital signs. Normal blood can meet the demands of human life activities and the blood supply to major organs. Too low blood pressure can severely affect human health and even endanger life. Normal blood pressure ranges from 90 to 140 mmHg for systolic and 60 to 90 mmHg for diastolic pressure. A systolic pressure below 90 mmHg and a diastolic pressure below 60 mmHg is considered low blood pressure. Diagnosis should also take into account underlying diseases, clinical symptoms, and other factors.
What is the range for low blood pressure?
Blood pressure below normal is clinically diagnosed as hypotension. Normal blood pressure ranges from 90 to 140 mm Hg systolic and 60 to 90 mm Hg diastolic. If the systolic pressure is below 90 mm Hg and the diastolic pressure is below 60 mm Hg, it is clinically diagnosed as hypotension. Symptoms of hypotension often include fatigue, dizziness, palpitations, shortness of breath, and darkening before the eyes. Mild hypotension may not present any clinical symptoms, while severe hypotension requires treatment based on clinical symptoms and the underlying disease to correct it.
How to deal with low blood pressure?
The management of low blood pressure requires different approaches depending on the cause of the hypotension and the severity of the condition. For mild hypotension not caused by a primary disease, it is important to rest, avoid staying up late, and consume more broth to stabilize or increase blood pressure. Hypotension caused by a disease, especially severe hypotension, requires emergency treatment in a hospital. Severe hypotension can be life-threatening and may require the use of vasoactive drugs, replenishment of blood volume, and other emergency measures to improve blood supply to the periphery and ensure blood supply to vital organs.
Is low blood pressure dangerous?
Severe hypotension is very dangerous. Hypotension is a diagnostic indicator of shock. Excessively low blood pressure leads to insufficient perfusion of the microcirculation, especially in vital organs such as the brain, heart, and kidneys, which can cause ischemia and hypoxia, leading to the failure of these organs and endangering life safety. Therefore, the occurrence of hypotension, especially severe hypotension, requires active resuscitation. Initially, it is necessary to administer fluids to supplement blood volume and make corrections, while also using some vasopressor medications to treat the disease causing the hypotension, achieving a blood pressure-raising effect to save lives.
symptoms of low blood pressure
Next, let us introduce some symptoms of low blood pressure. Actually, low blood pressure is divided into physiological and pathological low blood pressure. Generally speaking, physiological low blood pressure is asymptomatic, while pathological low blood pressure might have six major types of symptoms: The first type is fatigue and weakness, especially in the morning. Patients may feel listless and weak in their limbs which can improve after a nap or rest, but the fatigue may return in the afternoon or evening; The second type of symptoms includes headaches and dizziness. Among patients with low blood pressure, headaches are a common complaint, often occurring after intense mental activity or physical exertion. The nature and severity of headaches can vary, often manifesting as dull pain in the temporal or occipital region, but can also be intense pulsating pain or numb pain. Dizziness can vary in severity; mild cases involve blackout vision and vertigo, while severe cases can lead to fainting spells and even collapse, often occurring during sudden changes in body position, or when moving from a squatting to a standing position; The third type of symptoms involves chest pain or discomfort in the cardiac area, where patients with low blood pressure often experience such discomfort; The fourth type involves neurological dysfunctions, which can manifest as lethargy, reduced memory, sleep disturbances or insomnia, and severe cases may show signs of autonomic dysfunction. Symptoms might include pale skin, mild cyanosis, fluctuations between feeling cold and hot, sensations of ants crawling, or numbness in hands and feet; The fifth type of symptoms is reduced endocrine function, primarily shown as insufficient levels of substances like adrenaline and noradrenaline. Some patients may exhibit reduced blood sugar levels or decreased sexual function; The sixth type of symptoms includes poor appetite, abdominal discomfort, indigestion, or increased red blood cell count, decreased white blood cell count, reduced immunity, making infections more likely, etc.
