DIY rectal irrigation, fantastic,
My way,
Buy a plastic bidet spray head (AKA arabian shower)and 1 or 2 m of shower tube.
Sit on toilet and sort out where the shower tube gets plumbed in so you can comfortably reach your anus. Include an off/on valve to adjust water press and to isolate the system if a leak occurs. Try left/right to find the best position.
Now push flattish shower head against, not in your anus (anal sphincter), and squirt some water into rectum .Remove shower head and do a normal push into the bowl. hopefully there will be a satisfying ‘’ plonk’’
Repeat it
How much or how often is a matter of experimenting.however not’’ overfill’'and keep water press low to avoid stretching muscles.
Twice a day should be adequate. I do it the same time every day
Keep doing all the other anti constipation procedures.
Oh, don’t forget to inform your partner. and gp if it works well for you.
Lots of web info , my procedure seems much simpler and quicker.
I cannot remember ever having had to push or strain since I started this procedure.
