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 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.

The harm of low blood pressure

Low blood pressure can pose certain risks to the body, especially when it is persistently low, which may lead to insufficient blood supply to vital organs. The brain, particularly sensitive to ischemia and hypoxia, can suffer from inadequate blood supply due to prolonged low blood pressure, or even experience strokes. Low blood pressure can also lead to insufficient cardiac blood supply, causing ischemic heart disease. In particular, long-term low blood pressure can damage the kidneys, leading to renal failure and causing irreversible pathological changes. Therefore, patients with chronic low blood pressure should receive active treatment to alleviate their condition and protect vital organs.

How to deal with low blood pressure?

Low blood pressure in medicine refers to a systolic pressure below 90mmHg and a diastolic pressure below 60mmHg. So, what should one do after being diagnosed with low blood pressure? First, a formal examination is necessary, such as a blood test, to see if anemia might be causing the low blood pressure. Additionally, carrying out a cardiac ultrasound and an electrocardiogram (ECG) to check for potential heart diseases is advisable. Second, if anemia, heart diseases, or other conditions are ruled out as causes of the low blood pressure, appropriate medication can be taken to raise the blood pressure. For instance, certain traditional Chinese medicines, ginseng, Codonopsis pilosula, Glehnia littoralis, and Pseudostellaria heterophylla, can be helpful. One can take Chinese herbal decoctions under the guidance of a qualified Traditional Chinese Medicine doctor to help increase blood pressure. (Specific medications should be used under the guidance of a doctor; do not self-medicate.)

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.

What blood pressure is considered low blood pressure?

Systolic blood pressure lower than 90 mmHg and diastolic blood pressure lower than 60 mmHg are considered hypotension. Hypotension is divided into physiological hypotension and pathological hypotension. Physiological hypotension generally has no symptoms and does not require special treatment. Patients with pathological hypotension often experience symptoms such as dizziness, fainting, blurred vision, nausea, etc., and need to be treated according to the cause. Hypotension patients often have postural hypotension and postprandial hypotension. The normal blood pressure range for adult males and females of any age is systolic pressure between 90 to 139 mmHg and/or diastolic pressure between 60 to 89 mmHg.
