One day, when I was 5, I wasn’t feeling well, so Mom, an RN, decided to give me some enemas. I watched as she made soapy water in the bathroom sink and then scooped several cups of the soapy water into her enema bag. Soon, I was lying over her lap as she sat on the edge of the tub. After giving me the enema, she withdrew the nozzle, had me stand up and checked my tummy. She decided I could take more, so she added more water to the bag, had me lie on her lap again, and re-introduced the nozzle into me. She had me lie there for a few minutes before removing the nozzle and had me expel the enema as she refilled the bag, adding two more cups of soapy water.
Again, after my second enema drained into me, she had me stand up and checked my belly again and decided I could hold some more, so she added more water to the bag and then drained it into me.
The process was repeated for my third enema and finally we found my capacity. That volume was noted by her and subsequent enemas were that volume, though she always encouraged me to take as much as I could hold. I would watch as she scooped the soapy water into the bag and I knew how many cupsful she’d give me, and sometimes saw her add an extra one without saying anything. Eager to please her, I never said anything about the extra water and strained to take it, as I wanted to please her.
Whether I got a bulb enema or a bag enema, she knew exactly how much water I was going to get. I got soapsuds enemas from a bulb, with the water held in a big measuring cup so we could both watch how much I was receiving, as each delivery from the bulb could vary. Sometimes, she'd sneak an extra bulbful into me, which really filled me up.
Rinse enemas were given with her bag. Eventually, she’d totally fill the bag, even though I couldn’t fully drain it, but she’d have me take as much as I could hold, to take a “big boy” enema. My goal was to take the whole bag, and I was very proud, though very uncomfortable for a while, the day I heard the bag gurgle, indicating I had reached that milestone!
So, over time, Mom increased my capacity, though not all of the increase was due to me growing older. Some of it was her stretching my colon with the increased volume. By the time I was 9 or 10, I was able to hold a full 2 quarts. After that, she’d have a second bag ready for when the first bag emptied.
I still take high volume enemas, and as someone has noted, “The colon doesn't really stretch much without fairly intense pain…” As hard as I try, my limit is 5-3/4 quarts. Someday, I’ll take a full 6 quarts.
