A temporary loss of consciousness is known as fainting, sometimes called passing out or syncope. It occurs due to a sudden decrease in blood supply to the brain. A typical episode lasts a few seconds to minutes. Most fainting spells are harmless.
Seek professional care if you experience any of the following symptoms
Generally, Faint can be related to:
QT prolongation syndrome is a heart signaling disorder that can cause fast, chaotic heartbeats (arrhythmias). It can be present from birth or develop later in life due to certain medical conditions, specific drugs, or mineral imbalances.
Neurally mediated syncope, also known as vasovagal syncope, is a sudden drop in heart rate and blood pressure that results in fainting. Common triggers include strain, stress, long periods of standing, exposure to heat, or emotionally upsetting situations (such as sight of blood).
A condition sometimes seen in young children. Spells most commonly occur around one year of age with a range of six months to four years. Up to 15 percent of cases may have an initial episode below the age of six months. The child may stop breathing for up to 1 minute, causing them to lose consciousness and tone. Although alarming to parents, this condition is common and can happen in healthy children, who will grow out of it as they age. Triggers for spells include frustration, pain, or fear.
Sometimes, Faint may be related to these serious diseases:
Suffocation (asphyxiation) occurs when the body doesn't receive enough oxygen. The most common causes are allergic reactions (throat closes up from swelling), drowning and foreign objects caught in the airway. Without quick intervention, it can result in loss of consciousness, brain damage, or death.
Acute Encephalopathy

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
