For as long as I can remember, dh has had pasty stools. They are dark brown, but not formed and they stick to the toilet bowl. Sometimes, there are noticeable food particles. He has a bowel movement 3 times a day, and they aren't small.
He has a very healthy diet and very little processed food. The bm's are always pasty, but it's worse when he eats beans (about 3-4 times a week). It's better when he eats more salads (spinach and lettuce). He said it's "almost normal" when he eats pasta (not whole wheat), which isn't very often, maybe once a week. He eats quite a bit of fruit. Yesterday he had a big bunch of grapes, a banana, an apple, and some strawberries. Often, he'll have a salad in there, too. In fact, his lunches at work are either beans and rice or a big salad. He has gone through periods of being meat-free and periods where he ate meat, but it never made a big difference in his bms. He has the occasional cheese, but otherwise, doesn't do much dairy
He hasn't had any excessive weight gain or loss. He needs to lose about 20 lbs. He has no pain, no bloating, no other digestive symptoms. He doesn't feel sick to his stomach, doesn't vomit. He's had a few streaks of blood over the years (3 or 4x in 10 years probably) which he chalked up to straining or hemmorroids. The last time was a year and a half ago. He has no skin problems. Oh, he does seem to pass a lot of gas, but I just chalked that up to his diet.
What could be going on? To me, pooping 3x a day is a lot, but the consistency is the most concerning thing. And the volume. If he had malabsorption, wouldn't he have other symptoms? Any thoughts?
