Some conditions are automatically disqualifying because by nature they present suddenly and unpredictably. Other conditions can be appropriately managed as they're not likely to come on suddenly and cause rapid incapacitation. There are any number of conditions which are compatible with holding a medical when asymptomatic, but wholly incompatible with flying during an active bout. That is why it's a legal requirement not to operate if you know or suspect that you're unfit to do so.
