what is happening after going in koma
Answers
Answer:
Whether someone fully returns to normal after being in a coma depends on what caused the coma and how badly the brain may have been hurt. Sometimes people who come out of comas are just as they were before — they can remember what happened to them before the coma and can do everything they used to do

hello
The word "coma" itself emerged from the Greek for "deep sleep" (koma) in around the 17th century, and methods throughout history for helping those in comas have included bloodletting from the head, emptying the stomach, cooling the body dramatically, blistering, laxatives and all kinds of deeply unpleasant treatments. We know now that coma medicine is a deeply complex and neurologically labyrinthine field. So what actually happens, on a basic level, to the body when it's in a coma?

So what actually happens, on a basic level, to the body when it's in a coma?Comas are very different from sleep. They're a variety of unconsciousness whereby the patient cannot be roused by any external stimuli, whether you tickle your feet or blow a trumpet in their ear. People in comas display neither reactivity — the responses of the body to things like light or touch — nor perceptivity — neurological responses like language or moving away from threats. Comas occur both as a result of trauma and as part of deliberate treatment by doctors (The Big Sick, the 2017 rom-com starring Kumail Nanjiani, tells the true story of his then-girlfriend's medically induced coma). And while the body in coma may look docile and completely inert, there's actually quite a lot going on under the surface.
Some people in comas will need respiratory help with an artificial breathing apparatus; all will require some way of keeping them hydrated and fed, a process usually done by IV injection into the veins. If coma patients are now lacking the reflexes to swallow and clear their airways of saliva, they'll choke or develop airway issues, and will need to be intubated (have an artificial breathing tube put in place).

Caused by prolonged inactivity, this kind of muscle wastage isn't just restricted to coma patients; muscles require continual use to maintain strength and size, and being still for long periods means they fade away.
