I'm not so sure this is always the case. Let's say a pilot fails an FAA medical because his blood pressure was too high. He receives treatment, including a blood pressure medication that is permitted by the FAA, and his blood pressure is brought under control and well within the standards set by the FAA.

Is that pilot now required to take and pass a subsequent FAA medical in order to be able to self-certify that he is in good health for aviation purposes? I don't see why a subsequent medical exam would be necessary for glider operations.
