How to identify low blood pressure symptoms

Low blood pressure, or hypotension, can be identified by some symptoms, such as dizziness, feeling faint and vision changes, such as blurred vision, for example. However, the best way to make sure the pressure is low blood pressure should be measured at home or at a pharmacy.

Low blood pressure is usually indicative that there is not enough blood flowing from the brain to the organs, resulting in the symptoms. It is considered a person has low blood pressure when the values are equal or less than 90 x 60 mmHg, popularly called 9 by 6.

To increase the pressure slightly, decreasing the discomfort you can lie down with the legs elevated or have a coffee with sugar or a juice, for example. Find out what to eat to when your blood pressure is low.

How to identify low blood pressure symptoms

Main symptoms of low blood pressure

The main symptoms for low blood pressure are:

  • Dizziness and vertigo;
  • Lack of energy and muscle weakness;
  • Feeling faint;
  • Out of breath;
  • Headache;
  • Heavy head and feeling of emptiness;
  • Pallor;
  • Dry mouth;
  • Drowsiness;
  • Nausea;
  • Blurred vision.

In addition, it is common to feel tired, have difficulty concentrating and feeling cold, and in most cases several symptoms appear at the same time. These signs arise because oxygen and nutrients are not distributed satisfactorily to the cells of the body.

What to to when your blood pressure is low

However, in most cases, low blood pressure with symptoms is a temporary and infrequent event. In these situations, to help alleviate discomfort you should:

  1. Sit with your head in the middle of your legs or lie down with your legs raised, your feet higher than your heart and head, in a cool, airy place to avoid fainting;
  2. Loosen your clothes to breathe better;
  3. Drink 1 orange and tomato juice that is rich in potassium and helps increase the pressure.

In addition, excessive sun exposure should be avoided and between 11 am and 16 pm and places with high humidity.

When low blood pressure occurs daily, pressure socks can be worn because hypotension can occur due to accumulation of blood in the legs. In addition, when orthostatic hypotension occurs due to rest in bed, one should sit for 2 minutes in bed before getting up.

Low blood pressure symptoms during pregnancy

Low blood pressure is common in early pregnancy. However it can cause great discomfort for the woman and put the baby at risk due to the symptoms which are usually:

  • Feeling weak, which can result in falling;
  • Blurry vision;
  • Dizziness;
  • Headache;
  • Feeling faint

If low pressure symptoms are frequent during pregnancy, it is important that you consult your obstetrician so that the best treatment can be recommended to relieve and avoid the symptoms.

What can cause it

Generally, low blood pressure drops due to decreased blood supply, especially when it is very hot, as blood vessels dilate and increase perspiration, decreasing the concentration of fluids in the body.

Low blood pressure may also be a side effect of some drugs such as diuretics, antidepressants, weight-loss drugs or antihypertensives, and the higher the dose, the greater the risk of having low blood pressure, and may result in prolonged fasting or vitamin B12 deficiency.

In addition, getting too much time lying down, especially at night or during the postoperative period of surgery can also lower blood pressure, causing postural hypotension, also known as orthostatic hypotension, which is when you get up suddenly and feel faint.

When to go to the doctor

It is essential to go to the emergency room or the hospital when your pressure remains low for more than 15 minutes and does not improve with the recommendations.

If you have these symptoms more than twice a month, you should go to the doctor to find out the cause of the problem, as it may be necessary to take medication like ephedrine, phenylephrine or fludrocortisone, for example.
