I am suffering from "sangahini" disease. There is mucus in stool and gradual weight loss. Generally I am constipated but when I take laxatives like Duphalac, kayam tablet and isabgol then I start having mucus in stool. Sometimes I have hard stool which causes bleeding and anal fissure. I have heard in "Sangrahni" disease milk should not be taken. Can you explain why? One more thing when I take Duphalac syrup for stool softening then I have mucus containing stool. Why this happens? Is it because of lactulose? Does lactulose harm intestines and produce more mucus? I think milk is forbidden in "Sangrahni" because of lactose in it which is difficult to digest by small intestine and might cause more mucus production, more gas and bloating. And I think since lactulose is similar to lactose that is why Duphalac syrup is causing mucus in my stool. Am I right? Other than Duphalac which stool softener should I use so that it doesn't produce mucus in stool? Should I try Lactihep syrup or Sorbitol syrup or Polyethylene glycol 3350 sachet? Please help me in this regard.
