People with low blood pressure should be careful not to eat raw and cold foods in their diet. Instead, they should consume more warming, nourishing foods with high nutritional value and avoid foods that affect blood pressure, such as celery. Celery has a blood pressure-lowering effect, and regular consumption can decrease blood pressure. Those with low blood pressure should pay attention to adjusting their dietary structure, replenishing the calories needed by the body, and raising blood pressure. Regular consumption of lean meat, eggs, fish, shrimp, high-quality protein or some soy products, as well as fruits high in vitamins, can help increase blood pressure, improve overall blood supply, and protect vital organs.

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.

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.

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.

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.
