He got a Morgul Wound like Frodo, in that battle and lived with it for 14 years. That weakened him. Before that, however, he was a strong man. It seems like the effects were different though still crippling for whoever got them. His did not seem to turn him into a wraith but to cripple him, "shortened his days, and he became shrunken with pain".
