What is a Coma?

What is a Coma?

Coma is a state of prolonged unconsciousness that may be due to traumatic head injury, stroke, brain tumor, drug or alcohol intoxication, an underlying illness such as diabetes, or an infection. A coma is a definite medical emergency.

What Happens When Someone is in a Coma?

Someone in a coma is unaware and unconscious of their surroundings and cannot move and respond to voices, other sounds, or any kind of stimuli. The person is alive, but the brain is working at its lowest stage of alertness. You can’t shake and awaken someone who is in a coma.


Comas may be caused by the following, including:

  • Infections in the brain
  • A stroke
  • Chemical imbalances in the body due to other illnesses
  • Severe injury to the head that affects the brain
  • Drug overdose
  • Brain damage
  • Seizures

How Do People Look Out for Somebody in a Coma?

Someone in a coma must be cared for within a hospital setting, like the medical care unit (ICU) of the hospital. There, the person can get the necessary medical attention needed to get better.

Some comatose patients are unable to breathe on their own and may need the assistance of a ventilator. This is a machine that pumps air into the lungs through a tube placed in the windpipe.

A person in a coma needs extra attention and care as they are prone to developing other conditions like bedsore. Bedsores are open sores on the body that are due to lying in one place for too long.

Having a loved one go into a coma can quite often become very upsetting and extremely trying for an individual’s family. But it is encouraged that they continue to engage in small ways with someone in a coma, like playing music and talking to them. The patient may be able to still hear what’s going on, even if they can’t respond.


What Happens After?

A coma may last for an indefinite amount of time. There are moments when an individual stays under a coma for days, weeks, months, or even years and does very little except breathe on their own.

Most people do come out of comas.

On TV, a person coming out of a coma is usually portrayed as simply “waking up” and resuming life normally. But in real life, this rarely is the case. Coming out of a coma, an individual probably is most probably confused and disoriented. It will take time for the person to start feeling better.

Whether the patient who is in a coma is able to return to normal and live a normal life depends on what caused the coma and the extent of the trauma or damage to the patient’s brain.

Other people may need therapy to relearn basic actions like tying their shoes, eating with a fork or spoon, or learning to be mobile and independent again. These patients may also have difficulty speaking or even remembering things.

Over time and with the assistance of therapists, however, patients recovering from a coma can make a lot of progress. They may not return to the exact level of health prior to their coma, but they can still live normally and enjoy life with their family and friends.
