I am having a colonoscopy friday and i am worried about anesthesia. ?

Short acting: anesthesia is used- very safe, unless you are allergic to Diprivan ( propofol ) or Versed (midazolam). All short acting and very safe.

Anesthesia : Many people are phobic about the loss of control anesthesia or even flying in a plane can produce. Everything in life has a risk but know that you are lowering the risk of colon cancer by a very temporary letting go of control in a safe environment. Peace and good health.
