Coma is a situation where a person is unconscious for a period of time without dying.
Coma is a state of unconsciousness in which a person cannot be awakened; fails to respond normally to painful stimuli, light, or sound; lacks a normal wake-sleep cycle; and does not initiate voluntary actions. A person in a state of coma is described as being comatose. A distinction is made in the medical community between a real coma and a medically induced coma, the former is a result of circumstances beyond the control of the medical community, while the latter is a means by which medical professionals may allow a patient’s injuries to heal in a controlled environment.
A comatose person exhibits a complete absence of wakefulness and is unable to consciously feel, speak, hear, or move.] For a patient to maintain consciousness, two important neurological components must function. The first is the cerebral cortex—the gray matter that forms the outer layer of the brain. The other is a structure located in the brain-stem, called Reticular activating system (R.A.S).
HERE’S WHAT HAPPENS WHEN YOU FALL IN COMA…
YOU CANNOT HEAR SOUND.
YOU CANNOT FELL PAIN OR ANY SENSE ON YOU WHOLE BODY.
YOU CANNOT TASTE FOOD. ( THERE WILL BE NO DIFFERENCE BETWEEN THE TASTE OF WATER AND TASTE OF JUICE..)
WHEN YOU COME OUT OF COMA, YOU WILL JUST FEEL LIKE YOU JUST WOKE UP FROM A REGULAR SLEEP.
YOUR HEART BEAT, YOU BLOOD CIRCULATION ETC WILL BE ALL RIGHT EXCEPT YOUR BODY DOESN’T FUNCTION AND YOU ARE LITERALLY LIKE A DEAD PERSON.
YOU CANNOT EVEN OPEN YOUR EYES.
HERE ARE SOME OF THE CAUSES OF COMA
Diabetes: If the blood sugar levels of a person with diabetes rise too much, this is known as hyperglycemia. If they become too low, this is hypoglycemia. If hyperglycemia or hypoglycemia continue for too long, a coma can result.
Hypoxia, or lack of oxygen: If the supply of oxygen to the brain is reduced or cut off, for example, during a heart attack, stroke, or near drowning, a coma may result.
Infections: Severe inflammation of the brain, spinal cord, or tissues surrounding the brain can result in coma. Examples include encephalitis or meningitis.
Toxins and drug overdose: Exposure to carbon monoxide can result in brain damage and coma, as can some drug overdoses.
Traumatic brain injuries: Road traffic accidents, sports injuries, and violent attacks that involve a blow to the head can cause coma.
