Blackness in front of my eyes when I stand up

The human body is a complex structure, and people will encounter some strange things in their daily activities. Blacking out in front of the eyes when standing up is a relatively strange thing that can be encountered in daily life. Whenever encountering this situation, many people will worry whether there is something wrong with their body. However, blacking out in front of the eyes when standing up is a very special disease problem. Today, let’s understand what the reason is for blacking out in front of the eyes when standing up.

Do you feel dizzy when you suddenly stand up?

This condition is called postural hypotension.

The symptom of orthostatic hypotension is that when we suddenly stand up while lying or squatting, our blood pressure will drop instantly, causing dizziness or even fainting, but it will recover on its own after a while.

This type of low blood pressure is common in the elderly, pregnant women, people who are bedridden for a long time, etc.

Studies have found that the use of antihypertensive drugs increases the incidence of orthostatic hypotension. Among them, low blood pressure in pregnant women is mostly temporary and will recover after giving birth.

For healthy young people, if they suddenly stand up while lying down or squatting, they may experience similar symptoms, so there is no need to worry.

So, from a medical perspective, what exactly is low blood pressure?

What is hypotension? Does it matter?

Normally, an adult's systolic blood pressure (commonly known as high blood pressure) is less than 90 mmHg or diastolic blood pressure (commonly known as low blood pressure) is less than 60 mmHg.

mmHg is considered low blood pressure.

However, this does not mean that you need to seek medical attention or take appropriate measures once your blood pressure drops below 90/60 mmHg.

First of all, the normal blood pressure range is based on surveys and statistics on a large number of people. Most people are normal within this range, and for a few people, even if their blood pressure is lower than 90/60 mmHg, it may be normal if they do not have corresponding symptoms.

This means that if your blood pressure is at 85/55 mmHg for a long time, but you don't feel any discomfort in your life, it doesn't matter if your blood pressure is a little lower.

Secondly, sleep, pregnancy, different body postures, eating different foods or taking certain medications can cause temporary changes in blood pressure, and such blood pressure fluctuations are also normal.

So, under what circumstances should we go to the hospital to seek medical help? Let’s continue looking at it.

When do you need to go to the hospital?

Occasionally having low blood pressure is not a big problem, but if it is low for a long time, you have to be careful.

If this situation persists for a long time, you should pay attention to whether you have dizziness, lack of concentration, fatigue, black spots in front of your eyes, blurred vision, nausea, lack of energy, fear of cold, or even fainting. If so, you need to go to the hospital to seek help from a doctor.

What should I pay attention to?

When symptomatic hypotension occurs, you must go to the hospital for treatment. It is critical and important to find out the cause, and targeted drug treatment is required.

Of course, we also need to cooperate with the treatment and improve the following lifestyles:

1. Ensure nutrition and eat more salt if necessary

Eating more salt can help raise blood pressure, but it may also increase the risk of heart failure (the risk is higher in the elderly), so before choosing whether to eat more salt and how much to eat, be sure to consult a doctor's advice, and then make some adjustments based on your physical condition.

2. Drink more water and less alcohol

Drinking water increases blood volume and reduces the risk of dehydration, but alcohol can cause blood pressure to drop by dilating blood vessels.

3. Wear compression stockings

Compression stockings can redistribute some of the blood volume in the lower limbs and relieve symptoms.

4. Elevate your lower limbs

If you experience related symptoms, be sure to lie down in bed immediately, raise your lower limbs above the level of your heart, so that the amount of blood returning to the heart increases and the symptoms are alleviated.

5. Patients with orthostatic hypotension

When you stand up, be sure to do it slowly to give your body time to adapt.
