The body’s natural response to physical stress such as surgery is the excessive secretion of steroids. These extra steroids enable the body to withstand the pressure better. If the patient takes steroids continuously, the body will not release more steroids during physical stress. For this reason, additional steroids are needed before and after surgery. Usually, one day before the operation, more steroid is prescribed and it continues until one day after the operation. The amount of steroid used during this period varies from 30 to 125 mg, and is injected into a vein every six hours. Usually, the extra steroid is stopped one day after the surgery and it is back to normal. As is common with steroid use, the amount of drug used during surgery must be determined for each person separately.
