Coma is a prolonged state of loss of consciousness that can be caused by a variety of problems – head trauma, stroke, brain tumor, drug or alcohol poisoning, or even an underlying condition like diabetes or infection.
Coma is a medical emergency. Rapid action is needed to keep life and brain functioning. Doctors usually order a series of blood tests and a brain scan to determine what is causing the coma so that appropriate treatment can begin.
A coma rarely lasts more than several weeks. People who have been unconscious for a long period of time can go into a persistent vegetative state or into brain death. Head trauma, coma Treatment in Khammam
The signs and symptoms of a coma are usually:
- eyes closed
- Depressed brainstem reflexes, such as B. Pupils that do not respond to light
- No limb reaction other than reflex movements
- No response to painful stimuli other than reflex movements
- Breathing irregularly
There are many types of problems that a coma can cause. Some examples are:
- Traumatic brain injuries. These are often caused by traffic accidents or acts of violence.
- Stroke. A decreased or interrupted blood supply to the brain (stroke) can be due to blocked arteries or a broken blood vessel.
- Tumor. Tumors in the brain or in the brain stem can cause a coma.
- Diabetes. Too high (hyperglycemia) or too low (hypoglycemia) blood sugar can cause coma.
- Lack of oxygen. People rescued from drowning or resuscitated after a heart attack are unable to wake up due to a lack of oxygen in the brain.
- Infections. Infections such as encephalitis and meningitis cause swelling of the brain, spinal cord, or the tissues around the brain. Severe cases of these infections can lead to brain damage or coma.
- Seizures. Ongoing seizures can lead to coma.
