If you read chapter 535, he was more or less, made completely human. So he will age, like a normal human. He lost his shinigami powers and was put into a human Gigai, I dare say the only reason why Shinji's gang and Urahara and friends, stayed young was because they all kept their shinigami powers. If you check the date of my post you'll see that i wrote that two weeks ago. LastationLover5000 already verified that his power lost was the reason of his aging.
