Typically, stomach-clean medications are meant to relieve constipation or facilitate bowel movements. Fibre supplements, mild laxatives, and medications containing lactulose or polythene glycol?which soften stool and facilitate bowel movements?are common choices. Along with these medications, consume fruits, vegetables, whole grains, and lots of water. Strong laxatives can lead to dehydration or cause the intestine to become dependent on them, so avoid using them regularly without a doctor's advise.
