Preparing for your appointment

By Mayo Clinic Staff

Coma is an emergency medical condition. If you are with a person who develops signs and symptoms of coma, call 911 or your local emergency number immediately.

When you arrive at the hospital, emergency room staff will need as much information as possible from family and friends about what happened to the affected person before the coma. On the way to the hospital, you may be asked the following questions:

  • Did the coma start abruptly or gradually?
  • Were there problems with vision, dizziness or numbness beforehand?
  • Does the affected person have any history of diabetes, seizures or strokes?
  • Did you notice any changes in the affected person's health in the time leading up to the coma, such as a fever or worsening headache?
  • Did you notice any changes in the affected person's ability to function in the time leading up to the coma, such as frequent falls or confusion?
  • Did the affected person use any prescription or nonprescription drugs?
