A temporary loss of consciousness is known as fainting, sometimes known as passing out or syncope. An abrupt decrease in blood supply to the brain causes it to happen. A typical incident lasts a few seconds to minutes. The majority of fainting spells are harmless.
Seek professional care if you experience any of the following symptoms
Losing consciousness
Anemia is a disorder where the body's tissues don't receive enough oxygen due to a lack of healthy red blood cells. There are several types of anemia with various causes, the most common being iron-deficiency anemia, which results from insufficient iron. Iron is needed to produce hemoglobin, a substance in red blood cells that helps carry oxygen.
Dissociative disorder is a mental disorder that involves experiencing a disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity. People with dissociative disorder escape reality in ways that are involuntary and unhealthy, causing problems with functioning in everyday life.
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 the sight of blood or something unpleasant.
These conditions involve issues with the heart's electrical conduction system. Signals may be transmitted too fast, too slow, or not at all to some areas of the heart. Both men and women are affected, and the risk increases with age.
