A basic tenet in medicine is that no harm should be done to the patient seeking treatment. The patient should leave the clinic or the hospital feeling much better than when he/she came in for the medical care. The World Patient Safety Day is celebrated on the 9th December every year to highlight the importance of the safety of patients who seek medical care.

This means that women with autoimmune disorders actually find the symptoms abating during pregnancy.
