Have you tried metamucil? It is the good fiber that helps form the stool but not bind you up. You can take other kinds like Citucil or Benefiber. I took gelcaps filled with metamucil as I hate drinking it mixed in fluids. I took 3 gelcaps before each meal. A dose is 5 so I took a little less than 2 doses as day. Some like to eat the metamucil wafers. Yogurt, bananas and baked chicken are good to add to the above list.
Trust us it will get better.
I think calmoseptine is the best ointment to use and if you don't have one already get a bidet sprayer or seat. I have the least expensive a sprayer attached to the water coming into the toilet. I bought a kit from a site called Diabetes and More for $50. It took my husband 10 minutes to install. I spray, think kitchen kind, clean my butt every time and use Charmin Ultra Soft to dab it dry. In the meantime sitz baths help as well. It is important to dab not wipe as there is more bile in our output now, we are going more and our butt got soft when we had our diverting ileo's.
The type of TP you use does matter. I didn't believe it in the beginning but was converted. Charmin Ultra Soft. You also need good wipes, I use baby wipes, when not at my bidet sprayer stool, and carry the purse size with when leaving the house.
Also I use to stand up, but over the stool and or move my leg around and wait for more poo to come out. Sometimes you just need to sit for a while or walk around for 5 minutes. The pouch is just learning it's job now but it does get better. I've read about some people going back to work at 6 weeks and think they all were nuts, lol. Just saying some recover faster than others, we are the same but all different.
