The FAA MedXPress Application will require you to provide comments or explanations for all items 18.a. through 18.y. The button will come active as you click on any specific medical problem in your history. Once you have done this for the FAA in the past, you will not need to repeat it. They have a button which stands for PREVIOUSLY REPORTED, NO CHANGE, so you will not have to repeat yourself for old conditions or health issues unless there have been any changes. Below is a sample screenshot:
