Low blood pressure

How low is considered low blood pressure?

Hypertension has a high incidence rate and is very harmful, so it is often regarded as a disaster. However, does low blood pressure mean normality? This is rarely paid attention to.

In fact, low blood pressure is not a "good thing". Severe low blood pressure may cause blurred vision, weakness, fainting, and even myocardial infarction or cerebral infarction due to insufficient blood supply to the cardiovascular and cerebrovascular systems .

But many people usually measure their blood pressure, but after the measurement they don’t know whether their blood pressure is normal.

For adults, normal blood pressure ranges are as follows

Systolic blood pressure: 90-140 mmHg

Diastolic blood pressure: 60~90 mmHg

That is to say, if the blood pressure is lower than 90/60 mmHg, we call it hypotension.

Is low blood pressure abnormal?

This does not mean that low blood pressure is abnormal. When diagnosing low blood pressure, what is more important is whether there are symptoms rather than whether it is below a certain value.

For example, physiological hypotension occurs in some healthy people. Although the blood pressure measurement value has reached the hypotension standard, no symptoms appear and generally no special treatment is required.

But another type of pathological hypotension is different. It refers to the lowering of blood pressure caused by certain diseases of the human body, such as chronic malnutrition, idiopathic or hypertrophic cardiomyopathy, aortic valve stenosis, etc.

Taking antidepressants and antihypertensive drugs may also cause hypotension, so patients with hypertension are also prone to hypotension . This type of hypotension caused by disease requires active treatment of the underlying disease, and blood pressure can gradually recover after the disease improves.

Several common conditions that cause low blood pressure

1. Constitutional hypotension

Elderly people and women with weak constitutions have low blood pressure, which is constitutional hypotension. Mild cases may not have any symptoms, while severe cases may experience mental fatigue, dizziness, headache, and even fainting. It is more obvious when the temperature is higher in summer.

2. Postural hypotension

Some people often experience dizziness when they stand up suddenly or for a long time. This is mostly caused by low blood pressure or low blood sugar.

3. Postprandial hypotension

After a meal, a large amount of blood flows to the digestive tract, resulting in reduced blood supply to the cardiovascular and cerebrovascular systems and hypotension, which is more common in the elderly.

Does low blood pressure need treatment?

If blood pressure is low for a long time but there are no uncomfortable symptoms, it is physiological hypotension and generally does not require special treatment .

However, if the symptoms of dizziness and blurred vision are very severe and lead to falls, unconsciousness, severe or repeated vomiting, or if chest tightness and palpitations develop into persistent chest pain that cannot be relieved , you need to go to the hospital for treatment immediately.

Four ways to raise blood pressure

Severe hypotension

Drug treatment is available

For those with no symptoms or mild symptoms

Daily health care methods

Raising blood pressure

1. Do more isometric exercises

Exercises such as plank support and hand gripper training are gentle in amplitude and suitable for patients with low blood pressure. They can enhance myocardial contractility, assist venous blood return, increase the amount of blood output by the heart, and increase blood pressure.

2. Eat some Qi-boosting foods

According to traditional Chinese medicine, people with insufficient Qi and blood usually have lower blood pressure. Eat more foods that replenish Qi and blood, warm the spleen and nourish the kidneys, such as lotus seeds, longans, jujubes, mulberries, etc. These foods can nourish the heart and blood, strengthen the spleen and nourish the brain.

3. Proper water and salt supplementation

If you suddenly encounter low blood pressure, you can supplement with light salt water to increase blood volume to raise blood pressure.

4. Improve nutrition and maintain healthy weight

Weight and blood pressure are closely related. Usually when weight increases, blood pressure also increases, so overweight people are more likely to suffer from high blood pressure.

It is recommended that people with low blood pressure and who are too thin strengthen their nutrition and gain weight appropriately.
