Triple bypass surgery takes between three and six hours depending on the location of the arteries and any complications that arise. Surgery is performed under general anesthesia. Recovery from the operation takes an average of eight weeks, according to the Mayo Clinic.
After surgery, patients typically spend one to two days in the intensive care unit before they are released to a regular hospital room. Most patients can go home after about a week, although patients should figure another six weeks before they can resume work and other more strenuous activities. Full recovery can take up to 12 weeks for some patients, reports the Mayo Clinic.
