Do you feel dizzy after squatting for a long time? It may not be low blood sugar! Be careful of this...

Have you had this experience?

After squatting down and suddenly standing up

Black spots and dizziness

Many people attribute this to hypoglycemia or anemia.

In fact, there is another possibility, that is

Low blood pressure

PART 01 How low is the blood pressure considered low?

Hypertension has a high incidence rate and is very harmful. It is often regarded as a scourge, but does low blood pressure mean it is normal? Few people pay attention to it. 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. However, many people usually measure their blood pressure, but after the measurement, they don’t know whether their blood pressure is normal. What kind of value is low blood pressure? For adults, the normal blood pressure range is usually: high blood pressure: 90 < high blood pressure < 140 mmHg low blood pressure: 60 < low blood pressure < 90 mmHg

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

PART 02 Is low blood pressure abnormal?

Note: 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. 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.

PART 03Several common situations 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.

PART 04Does low blood pressure require 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.

PART 05 Four ways to raise blood pressure

Severe hypotension can be treated with drugs. For those who are asymptomatic or have mild symptoms, blood pressure can be "raised" through daily health care methods.

1. Do more isometric contraction 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 food

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. Eat more fat

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.
