Green_Hilltop: Basically, I have a slighter slower digestive system than most people, although according to my Google searches there are plenty of others who have it the same - I used to go and poo only once a week, and that was normal for me. Now I usually go every three days.
For me, that's perfectly normal and feels okay, but it makes me wonder - how often do you guys need to poo? And how does it feel when you're constipated?
No one seemed to reply to you seriously, so here goes:
I once knew one guy who said something similar as you, ie. he normally goes to take a dump only 1-2 times a week. He seemed surprised others would have to go more often. I don't know if it matters, but he was a bit of obese (reason or consequence, I have no idea).
I regularly go to take a dump every day, sometimes even 2-3 times per day (but once a day it quite normal). I guess I eat quite a bit of fiber (dark rye bread daily, and usually also oat meal in the mornings or such; and lots of vegetables), but what seems to get my bowels really going is when I drink coffee. I usually drink my morning coffee when I come to work (1-2 hours after my breakfast at home), and I usually need to go to take a dump like 1-2 hours after that.
The only exception to my pooing routing is when I go to some new place, e.g. going abroad or to our summer cottage. Then my bowels seem to take a break from the daily routine and skip one or two days. I don't know what that's about. I don't fret about that too much though, I figure "it comes when it comes", I don't try to force it out or anything.
Now, my question to you is that if you really poo only e.g. once a week, I'd expect the turds to be extra large, and the toilet bowl get jammed from the amount of feces? Or do they shrink in your stomach during those days they travel through?
Anyway, I suggest you start eating oat meals, rye bread and lots of different kinds of raw vegetables daily, and drink coffee. Let's see how it affects your pooing habits.
EDIT: Oh and to your actual question: for instance when those 1-2 day skips happen, the only big difference I feel is that I tend to fart more often. Otherwise I feel pretty fine when constipated.
