Hello, welcome to HCM. You seemed to have an episode of syncope
. Syncope or passing out can be due to various reasons including fever, fasting long hours, taking in too little food and fluids, low blood pressure
, growth spurts physical exercise
in excess of the energy reserve of the body, emotional distress, and lack of sleep. More serious causes of fainting
include cardiac (heart-related) conditions such as an abnormal heart rhythm (an arrhythmia), wherein the heart beats too slowly, too rapidly, or too irregularly to pump enough blood to the brain. You must visit your doctor for complete evaluation. Wish you good health.
