What is fainting?
Fainting is defined as a loss of awareness or consciousness for an
interval of time. The medical term used to describe fainting is
syncope.
How does it occur?
Fainting occurs when the blood supply to the brain is not enough
for its functioning. This may happen in any condition when the
heart is not be able to pump enough blood to the brain as in case
of heart valve problems; and if the heart rate is either too slow
or too fast, it may also happen if the person is fasting for too
long resulting in fall in his blood sugar level or in a diabetic
patient.
What are the symptoms of fainting?
The symptoms that a patient may feel before fainting are heart
palpitations that is feeling or hearing the heart beating very
fast, nausea or a feeling of vomiting or dizziness, weakness,
palpitation and a black out.
How is it diagnosed?
The doctor should be consulted immediately to find out the cause.
The doctor will take the patient’s medical history and examine
him, check the blood pressure and pulse. He will also suggest you
some lab tests and electrocardiogram (ECG). The ECG is a record of
heartbeat. He may also suggest echocardiogram which is an
ultrasound scan of the heart, to find out any abnormality in the
heart valve. He may also suggest echocardiogram which is an
ultrasound scan of the heart, to find out any abnormality in the
heart valve.
How is it treated?
The treatment will depend upon the cause of fainting. In case of
abnormality in heartbeats, medicine will be prescribed. In case of
reduction of blood flow to the brain because of problems in the
blood vessels, specific blood flow increasing drugs may be
prescribed.
What first aid can be provided?
The patient returns to consciousness when normal blood flow to the
brain returns. The patient should be made to lie down for 10 to 15
minutes with his feet in a raised position. If the patient has
normal breathing, his legs should be raised above the level of his
chest as this will help in supplying more blood to the brain and
help the patient to come back to normal.
To prevent fainting in future, avoid sudden changes in posture and
intense physical activities.
