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.

How to alleviate low blood pressure

How to alleviate low blood pressure depends on the cause of the low blood pressure and the degree to which the blood pressure has decreased. For mild low blood pressure without any primary disease, it is necessary to rest and consume high-protein, high-nutritional foods, especially high intake of broth, chicken soup, ginseng, sea cucumber soup, etc., which can effectively raise blood pressure. If the low blood pressure is caused by a disease and the blood pressure is relatively low, it is necessary to treat the primary disease while correcting the blood pressure. First, blood volume should be supplemented to raise blood pressure. In severe cases, pressor drugs should be used, and when blood pressure reaches a normal level, it is maintained to supply blood to important organs.

What are the symptoms of low blood pressure?

Long-term low blood pressure can lead to general weakness, loss of appetite, palpitations, shortness of breath, dizziness, and blackouts. Due to the excessively low blood pressure, the important organs suffer from ischemia and hypoxia, causing symptoms of ischemia and hypoxia in various organs, especially cerebral hypoxia, which can manifest as nausea, vomiting, headaches, blackouts, and even fainting. Therefore, low blood pressure should be actively treated and improved. Severe low blood pressure requires the use of medications, replenishment of blood volume, and appropriate application of certain vasopressor drugs to raise blood pressure and maintain adequate blood supply to important organs.

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.

Does low blood pressure cause dizziness?

The main clinical symptoms of low blood pressure include dizziness, which is caused by ischemia and hypoxia in the brain due to low blood pressure. The primary causes of low blood pressure are insufficient cardiac contractile force, changes in vascular elasticity, and inadequate blood volume, leading to insufficient perfusion in the body and vital organs, causing ischemia and hypoxia. Dizziness is a major symptom of cerebral ischemia. Not only can severe dizziness cause headaches, but it can also lead to unconsciousness. Severe low blood pressure can cause confusion, apathy, and other symptoms, requiring active treatment to raise blood pressure.

Is low blood pressure serious?

Low blood pressure is a common and frequently occurring disease clinically. It often occurs in physically weak individuals, middle-aged and elderly people, or women during their physiological period, as well as people who do not pay attention to nutritional intake while dieting. It can also be seen in some diseases that cause low blood pressure. Low blood pressure caused by reasons such as diet and age is generally not too serious and can be managed by adjusting daily routines and dietary structures. However, low blood pressure caused by blood loss, allergies, heart failure, trauma, and other factors is a manifestation of shock and is very serious. In severe cases, it can be life-threatening and requires immediate emergency treatment.
