HI well come to HCM I really appreciate your concern, if this is the constipation and not being relived then chances if blood in stool would be likely so better try to relieve it and for that you have to drink more water, have more fiber containing diet, keep regular habit of going for defecation even in the absence of feeling but still be inside sit there no matter if you do not pass the stool for fifteen minuets or more try some Isabgol powder for stool softening hope this information helps.
