I have never read, written or talked about my bowel movements as much as I have since my surgery ??. Don’t know what is worse the constipation post surgery or the hideous, absolutely no warning diarrhoea, which I had. Took a couple of steps & … well you get the picture.
I added a soluble non swelling fibre to my diet. If I hadn’t gone for three days, I’d take a stool softener so there would be action the next day & so I’d keep on top of it.
But certainly, you’re not consuming much & your body will be absorbing every bit of nutrition from it it can at the moment. Don’t be surprised that when you do start to go more regularly that it’s small & regular might be every two days.
It does get better as you are able to eat more & are eating a wider variety of foods & food types.

I had Bypass.... but....
For probably 7-8 years I have suffered from IBS with constipation. I was on a prescription to have BM's. Nothing over the counter worked. It was horrible. Before surgery I was so worried about it getting worse since constipation is such a common problem after WLS. Honestly, it was my biggest concern over everything else!
So, POST OP: The first 2 days I had bad diarrhea. Not in large amounts because I wasn't eating, but it was all day long. Then I went from one extreme to the other complete constipation! UHG.. 6 days to be exact... my surgeon told me not to take my prescription without talking to him first so I finally called. He was on vacation so the office was waiting to get a response from him. In the meantime.. it came... SOOO hard.. SOOO painful. Took almost 2 hours on the toilet!! it hurt to sit down afterwards. Was ridiculous frankly! Then is was about another 3-4 days, a couple times of this less hard and painful each time. Then all a sudden I AM CURED! I am 3 months post op now and more regular than I have been my entire adult life!!! I have no problems going, almost every day sometimes every other. It is normal and easy and I take NO laxatives, supplements (for BM's) or prescriptions! Naturally regular and I must say it is wonderful. I never thought I would be so happy to poop!
I know a lot of people drink miralax every single day to keep them regular.
I really hope it works out for you and you find relief because I truly understand you suffering!

I hadn't pooped for five days after surgery so they told me to use a suppository laxative. I had tried all the prescription stool softeners and Miralax, nothing. The suppository worked in 15 minutes. I do use this still RARELY when I haven't gone in four days or so. You don't want to do a laxative every day, but Miralax is usually fine

it can take a week to have the first BM. And it's often a doozy! A lot of us take stool softeners to ease the "passage"...
just so you know, chronic constipation is a common issue after weight loss surgery (but usually not as bad as that first post-surgery one). Many of us take a capful of Miralax or stool softeners to stay on top of it.
