Srikanth strongly believes that prevention is better than cure. He is of the opinion that awareness is a key to prevent diseases.

Coma is also known as persistent vegetative state. It is a profound state of unconsciousness.

The term ‘coma’, has its roots in the Greek word κῶμα, which means deep sleep. It was used in the Hippocratic corpus (Epidemica).

Most comas end with eye opening and regaining of consciousness; however, 10 percent of patients who open their eyes fail to regain consciousness.

A fully awake patient has a Glasgow Coma Score of 15. A person who is dead has a Glasgow Coma Scale of 3.

People may come out of a coma with physical, intellectual, and psychological problems. Some people may remain in a coma for years or even decades.

Richard Hanson, 66, who spent 35 days in a coma while being treated for coronavirus at King's Mill Hospital, in Sutton in Ashfield, returned home on June 4 2020.

He was also treated for pneumonia and kidney failure. He was in the hospital for 60 days.

Coma is usually caused by injury to the brain or the central nervous system. Hyperglycemia or hypoglycemia can result in coma.

Hypoxia, infection, toxins and drug overdose are other known causes of coma.

Coma is a medical emergency and needs immediate medical attention.

The goal of treatment is to prevent further physical and neurological damage.

Physical therapy may be administered to prevent bone, joint, or muscle deformities.

Respiration and circulation is monitored and maintained, using intubation and ventilation.

Surgery is performed in cases of haemorrhage. Antibiotics are used to treat infection.

Over time, with the help of therapists, many individuals who have been in coma have made good progress.

They may not be exactly like how they were before slipping into coma, but they are doing many things and enjoying life.


One of the leading causes of coma is traffic accidents, so it is important to follow traffic and safety laws.

Eat healthy, natural food. Sleep for at least seven hours, during night hours. Do yoga daily. Never use tobacco products.

Avoid excessive consumption of alcoholic beverages. Maintain healthy blood sugar levels.
