Hi Joe (Lady Astor and Winston send their regards :))
There is a provision in the Code of Canon Law re the elderly fasting before Holy communion .
“The Eucharistic fast has now been reduced to one hour - abstaining from food and drink (except water). The time is computed up to the actual time of reception. The sick, even if not confined to bed, and those actually engaged in caring for them at the time, need not observe any period of fasting. The same applies to the elderly, according to the new Code of Canon Law # 919. 3.”
That’s taken from the article here ewtn.com/faith/teachings/euchb2.htm
The Canon itself doesn’t stipulate any certain age (it would end up being discriminatory if it did. Illnesses and frailty are not totally age-specific). Here’s the exact wording from the Latin-English edition of THE CODE OF CANON LAW ANNOTATED by the University of Navarra’s and St. Paul University’s faculties of Canon Law (1993 Edition, Wilson & Lafleur):
The elderly and those who are suffering from some illness, as well as those who care for them, may receive the Blessed Eucharist even if within the preceding hour they have consumed something.
A confessor is also able to grant the penitent (any age) a dispensation re the preparatory 1hour fast before receiving Holy Communion.
I don’t know if there is any other stuff. These are simply the ones I know of.
…Really hope your health is OK.
