Different Causes Of Fainting

Fainting relates to a sudden lack of awareness, accompanied by an immediate and complete restoration. In patients with heart disease, fainting can be a danger signal that unexpected cardiac arrest is about to happen.

Oftentimes, fainting is not an indicator of a life threatening problem, though some individuals who faint often have a significant underlying health condition.

In non elderly individuals, over seventy five percent of instances of fainting are not connected with an underlying medical problem. A supply of oxygen rich blood should be pumped to the brain without gap; when this does not happen, the individual faints.

In several cases, people faint when there is an emotional reaction to a stimulus, like anxiety about harm, heat exposure, the vision of blood or extreme pain. Heart rhythm issues and a number of disorders of the heart can cause fainting.

Any trouble with the arrangement of the heart that interferes with the blood flow may cause fainting. In several cases, the condition may interfere with flow of blood out from the left ventricle and may cause fainting. Drinking alcohol may cause arteries to expand, causing blood pressure level to fall and cause one to faint.

Gathering as much information as possible about events that happened before, during, and following a fainting episode might be useful to determine the possible cause of fainting. An individual who faints during exercise is more prone to have an obstruction to flow of blood or ventricular tachycardia as a reason.

Details about current medicines and pre existing health conditions like diabetes mellitus, heart problems, or mental disorder might help pinpoint the main cause of fainting.

The doctor will measure your heartbeat rate and blood pressure level to help determine if a rhythm disruption or low blood pressure level caused fainting. In case the main cause of fainting is not readily apparent, numerous medical tests can be conducted to help establish the main cause of fainting.
