Hi, Welcome to HCM.
Stools with blood/mucus can be due to various causes such as injury
to the digestive tract, fissure, constipation
or even other critical conditions such as intestinal cancer. Consume a lot of hot water to see if you can pass out all the stools. Also go on a whole day fruit diet(include banana all the three times). On the second day, you can consume fruits and vegetables and no other refined foods. Do not stop on water consumtion. If the situation still persists, visit a doctor to check on the condition.
