Light-headedness, dizziness or balance disorders may be due to a temporary reduction in blood flow to the brain. Sudden loss of consciousness usually means that blood flow to the brain is severely reduced. Fainting or prolonged dizziness is a potentially serious situation that will require medical attention.
Why am I dizzy?
Dizziness is a term used to describe anything from fainting and light-headedness. Dizziness causes you to become disoriented and it seems as if your surroundings are spinning or everything within your own body seems to be spinning. Dizziness can be accompanied by balance disorders where you get the feeling that you can no longer keep your balance and are constantly falling over. Usually this condition will be harmless and short-lived.
Causes of dizziness and fainting
With dizziness you get the feeling that you are going to faint. Fainting is a sudden loss of consciousness, usually temporary and usually caused by a lack of blood and oxygen to the brain. The lack of oxygen in the brain has many possible causes. This can be caused by medical conditions such as heart disease , a heavy cough or circulatory disorders such as anemia .
Getting up too quickly or severe fatigue can also lead to dizziness or fainting. This can drastically reduce blood flow, causing you to feel a slight feeling of weakness. Almost everyone suffers from this at some point, but everyone’s body reacts differently. For some, this feeling will disappear after a few seconds, while for others it can be more serious, resulting in fainting.
Fainting due to sudden event
A final factor, but also a cause that should not be underestimated, is that one can faint due to an event that one did not expect. For example, fear of something such as seeing blood or receiving bad news that one did not expect can be the result of fainting. Accumulating too much stress can also overload the body, which can cause this.
What to do about fainting?
If you feel yourself becoming dizzy, fainting or seeing spots in front of your eyes, it is important that you lie down as quickly as possible and pull your legs up. This allows the blood to flow better to the heart. If you see someone faint, you try to catch him or her so that they cannot injure themselves. Place the person flat on the ground and check the airways and pulse and call emergency care. Loosen tight clothing.
When to go to the doctor?
Mild complaints that last for weeks or months can indicate serious nervous system disorders. Dizziness and fainting can have various causes, which means that the doctor in question will have to perform various tests.
Go to the doctor or emergency room immediately if:
- You take medication for high blood pressure
- You were injured when you fainted
- If the fainting is accompanied by headache, chest pain or irregular heartbeat
- When fainting is caused by poor breathing
- The fainting is the result of sunstroke
