Fasting Before Communion

A very ancient Catholic practice: we prepare ourselves to receive the Lord, by not taking food for one hour before we receive Holy Communion.

This does not apply:

to Medicines

or to Water

These may be taken by anyone, any time. 

if you are pregnant, diabetic or need to eat regularly for health reasons:

YOU MUST NOT FAST!

The point of this preparation is to make sure that you thinking of the importance of what you are doing before you get to church.  But it isn't supposed to make you ill or to make you feel ill.
