Did the medieval church or hinder medical progress?

Medical practice was actually hindered by the church during the medieval era because the doctors could only follow the practices of ancient writers like Hippocrates and Galen. Even though these people were essential in medical development, there were many more discoveries that were made during that time that the doctors did not know about. This was because the church believed that the newer ideas were against the ideologies of the church. Because of this, they made doctors not question the works of ancient writers even though some of their information are already outdated.
