Coma is caused by many things like head injury, brain tumor, heat stroke, drug or alcohol, or many illnesses like diabetes or infection.  Discontinuing the life-supporting system results in the death of someone so we don’t need to plug it. So, if any person has suffered from any brain injury but not a coma they can breathe properly for one to two days as soon as they die.

There are many things that can increase the time of a person who is in a coma. If the sugar level increases or decreases for a long period of time coma is affected directly.

As stated above if any heart stroke or heart attack occurs as it is due to lack of oxygen supply to the brain, then coma may results. Even drowning can also result in a coma. If any infection has happened in the brain or tissues present in the brain then it will directly increase the coma and so increasing the time to be in a coma.

Many a time drug overdose or medicines also causes coma. As carbon monoxide is harmful gas so its mere presence affects the brain. Accidents or attacks directly affect the head so may result in a coma. Coma can vary from days to weeks to months to years.

Many people follow a pattern to recover soon from it. Since each patient is different so there are chances that they are unable to follow the exact stages. There are 4 stages of recovery in a coma: the first one is unresponsive, the second is early responses, the third is confused and agitated and the last one is the high-level response.
