I too struggle with hemorrhoids, both external and internal. When internal hemorrhoids are flared they can flatten stools or make them pretty thin... I'm guessing because there is only so much room in the colon and even less when there is an obstruction.
Those of us with constipation and hemorroids probably should drink more than the recommended 8 glasses of water a day too. I've gotten to where I can drink about 10 or 11 glasses a day and not feel like I'm floating
Laxatives can irritate the colon more so, and you say that fiber pills aren't working for you, so maybe try some fruit smoothies without dairy. They usually help get things moving for me and they're easy to make too.
As difficult as it is to not strain, don't do it. It will make things worse. Sometimes when I'm having a hard time with a bm I do deep breathing exercises. Sounds weird, but it helps calm my body and don't strain so much.
Also, stay away from foods that will worsen constipation and hemorrhoids, like dairy and caffiene.
Hope this helps. Nicole
