It often happens that in our surroundings, inside the house, in the community, on the street in the subway, in shops and commercial passages, we come across a person who has fainted or has a faint (medical term). In these cases, it is better to know how to deal with the person.

In the following, we will tell you what solutions you can take, When you encounter someone who has a faint.


What does faint mean?

It means a sudden loss of consciousness, which is a temporary loss of consciousness and is usually due to impaired delivery of sufficient oxygen to the brain tissue.

This attack of fainting occurs when not enough oxygen reaches the brain tissue. There are various reasons for the lack of oxygen reaching the brain, for example, fitting may occur following a decrease in blood pressure, decreased blood flow to the heart, and other cardiovascular events. Also, fainting may not be due to a medical problem, so all those who have fainting should be examined by an experienced doctor as soon as possible to determine the underlying cause of fainting.

The person should also be under emergency care until the symptoms are completely gone. It is said that people who experience multiple and frequent fainting spells should see a doctor and undergo the necessary examinations.

Here are some tips that you should pay attention:

These fainting spells usually occur after not enough blood reaches the brain tissue

Another point is that people who have fainted must be examined urgently

Fainting should be checked urgently to determine the cause.


Faint signs

Symptoms of fainting include:

  • Feeling of falling
  • Blurred vision
  • Confusion


What happens to the body when fainting?

The causes of fainting are very different and varied:

  • Dehydration
  • Low blood pressure
  • Alcohol abuse
  • And sugar drop
  • And some serious problems such as cardiovascular problems or cardiac arrhythmias

Therefore, treatment will depend only on the underlying cause

We said that Faint occurs when not enough oxygen reaches the brain tissue, that is, the oxygen supply to the brain cells decreases. This oxygen disruption can be due to cardiovascular problems or carbon monoxide poisoning, in other words, it is said that fainting is probably a defense mechanism that helps a person survive.

If the flow of blood and oxygen to the brain is significantly reduced, the body will cut off and restrict the blood flow to various organs of the body that are not vitally active so that more blood can reach the brain tissue.

In this way, as a result of diverting and reducing the blood flow of non-vital organs of the body, more blood will reach the brain and vital organs.

When the brain notices a decrease in oxygen at this time, the body begins to breathe faster or to increase respiratory ventilation so that the oxygen in the blood returns to its original level.

The heart rate may also rise to increase blood flow.

An increase in heart rate is very common when there is a decrease in blood flow to the brain, which causes a drop in blood pressure in the organs of the body. As a result, our brains receive more blood at the expense of other organs.

It is said that increased pulmonary ventilation or ventilation of the lungs along with changes in blood pressure can cause short-term and temporary loss of consciousness, muscle weakness, and eventually fainting.

When a person faints, you should know that there can be a variety of underlying causes for him. In this section, we want to introduce these causes.

Fainting can occur from cardiovascular as well as neurological causes

Fainting with cardiac or neurological causes occurs when a factor causes a brief disturbance in the functioning of the autonomic nervous system and the body, which is called indirect syncope or NMS.

The autonomic nervous system and the human autonomic nervous system have different functions. This system works by affecting heart rate, digestion, respiration, respiration rate, salivation, pupil size, urination, and sexual arousal.

As you can see, many of the above actions are performed unconsciously, some of them, such as breathing, can be done consciously. With some disorders of the autonomic nervous system, blood pressure drops, heart rate decreases, and heart rhythm and heart activity slow or stop. All of this causes a temporary interruption in blood flow and oxygen supply to the brain and the occurrence of fainting.

Possible factors that can alter the function of the autonomic nervous system and fainting include:

Seeing things that are unpleasant, such as blood and wounds.

Suddenly, if a person is exposed to an unpleasant scene, he may get faiting

Shame and extreme embarrassment in public

Sudden emotional distress, for example, when bad news reaches a person

When a person stands for a very long time

And when the person is in a hot and closed place for a long time

Another category is causes that are related to a job or situation and their cause is physical, for example, fainting can occur due to the following issues:

  • Laughing
  • Coughing
  • Breathing
  • To urinate
  • Defecate
  • Physical activities such as lifting weights and heavy objects

These are some of the things that can cause fainting.

When situational hypotension occurs, such as when a person sits or lies down quickly, gets up, or stands up, gravity causes the body's blood to accumulate in the legs. In the same way, in other places there is less blood inside the arteries and less blood reaches the brain. Normally the body will respond to this state with reactive contractions in the walls of the arteries. This stabilizes blood pressure.

However, if a factor interferes with the process of stabilizing blood pressure, there is a decrease in oxygen supply and blood flow to the brain, which leads to confusion and fainting.


Causes of fainting

Among the causes that cause a person to have a faint can be mentioned the following:


  • dehydration

If for any reason your body dehydrates, your blood pressure will also drop. This will cause the blood supply and subsequently oxygen to the brain to be disrupted, slowed down and the person to faint.


  • Untreated diabetes mellitus

People with diabetes mellitus who have uncontrolled blood sugar have excessive urination. This causes them to lose too much water and become dehydrated. High blood sugar can also damage the arteries and autonomic nervous system, which are responsible for regulating heart activity and vasoconstriction, and these people can experience more fluctuations in blood pressure.


  • medicines

A class of drugs called beta-blockers and some antihypertensive drugs can cause a drop in blood pressure and fainting in some users of these drugs. Also, some people may experience fainting after consuming a large amount of alcohol in a short time.


  • Neurological diseases

Like Parkinson's disease, as well as other neurological diseases that can cause low blood pressure.


  • Carotid Sinus Syndrome

Pressure on pressure receptors or pressure sensors located in the carotid arteries in the neck can cause fainting. This pressure sensor is known as the carotid sinus. The carotid artery is actually a pathway that carries blood to the brain. If the carotid sinus is disrupted for any reason, a mild physical stimulation may cause the blood pressure to drop and the person to faint. For example, a sudden change in head and neck direction to Side, wearing a dress with a tight collar, tying and pressing on the neck while shaving can irritate the carotid sinus in some people and lead to fainting.


What is the treatment  for fainting? How should we deal with a person who has fainting?

If you see a person who has this problem, know that he must be examined to determine the cause of fainting and, if necessary, must be fully treated.


Treatment can prevent recurrence of fainting or reduce the number of faints. Often a person with a faint does not need additional treatment. To prevent recurrence of fainting, the person must be examined by a doctor to determine the cause.

In other words, it is necessary to know the cause of fainting in order to prevent the recurrence of fainting and subsequent injuries during fainting. If you see a person having a faint in the street, the doctor and nurse should be informed that the treatment team can carefully determine the cause of the fit and determine for the patient what measures should be taken to prevent recurrence of fainting.


What are the symptoms of fainting or faint syncope?

  • The person feels dizzy and light-headed before fainting
  • The person feels generalized weakness before fainting
  • The person may see black dots
  • The person has paleness and may also hear extra sounds in the ear.


In the following, the factors that cause fainting are titrated:

  • Dehydration, for example, due to excessive sweating and diarrhea, vomiting
  • Hunger and not eating for a long time
  • Long standing
  • Underlying malaise and boredom
  • the fear
  • Severe pain
  • Respiratory attack
  • Sudden awakening from a lying or sitting position
  • Presence in closed environments that are hot and humid or in response to a stimulus such as a very bad smell or seeing blood or needles

Among the physical factors that can be more serious and dangerous reasons for fainting are the following:

  • Heart disease
  • Cardiac arrhythmias
  • Lower blood sugar
  • anemia
  • Pregnancy
  • Anaphylaxis
  • Allergic reactions
  • Consumption of toxins
  • Drug use
  • Allergy to drugs
  • Exercise and strenuous activity
  • Lifting heavy equipment and heavy weights


Differential Diagnosis

Another point is that there are situations similar to fainting, in fact there are other problems that look like fainting.

For example, migraine headaches, seizures, panic attacks, and rapid breathing that can cause dizziness.


How can we help someone who has fainted?

If you encounter a person who has fainted, do the following:

  • Calm the environment
  • Control the persons breathing
  • Notify the emergency department if necessary
  • It is better for the person who has fainted to be in a horizontal position with nothing under his head and to raise his legs or, if possible, to sit down and lower his head so that he is between his knees.
  • Remove anything extra that covers the neck, such as a tie scarf, collar button, etc.
  • The treatment team needs to describe exactly what happened, in other words, the history provided is very effective in examining, diagnosing, and initiating treatment.


When is an emergency visit to the medical center necessary?

If you encounter a person who has fainted and the person has one or more of the following symptoms, you should take him or her to a well-equipped medical center as soon as possible or call the emergency room immediately.

  • If the patient has stopped breathing
  • If the patient has lost consciousness
  • Change in speaking
  • Vision changes
  • And changes in the body's ability to move


Concluding remarks

Fainting is a sudden and temporary loss of consciousness accompanied by a rapid return to normal.

Before fainting, people may feel dizzy, hot, cold, or pale just before they faint, or they may experience nausea.
