Some home remedies for diarrhea include taking plenty of small sips of fluids throughout the day (preferably water), eating only mild foods such as salt crackers and taking a home probiotic that contains Lactobacillus to help the body with digestion, according to WebMD. It is also best to avoid chewing gum, milk, spicy foods, caffeine and alcohol while the body is recovering, notes Mayo Clinic.
It is also recommended to try to slowly work in semisolid foods that have a lower fiber content. Once the salt crackers are easily digested, try adding toast, rice, chicken and eggs. The diarrhea should begin to decrease on its own after a period of a few days.
While not entirely a home remedy, over-the-counter antidiarrheal medicine can help people who have experienced diarrhea symptoms for more than 6 hours, notes WebMD. Thickening mixtures are also a good solution because they can help to thicken the stool, which makes it easier to pass and not in the form of diarrhea. However, doctors warn that these medications should not be used when blood or a fever accompanies the diarrhea. If a person does not see their diarrhea subside after 48 hours, then it is time to go to the doctor's office for treatment.
