The causes of regeneration, especially amongst Time Lords, were many and varied.

They ran the gamut from simple desire to change to sentencing for convictions, to life-threatening maladies, to blunt-force trauma. While all of these might have been cause for alarm in humans, Time Lords sometimes expressed much less concern. As the Twelfth Doctor once told Clara, "Death [was] Time Lord for man-flu".
