Hello Welcome to health care magic Dear patient, constipation with passage of pellet like stools is seen in irritable bowel syndrome which is a fuctional disorder of the gut, it is not any serious condition but it just upsets the patient too much, it is generally helped by taking good amounts of fluid oralley, doing regular exercise to increase bowel movements, consuming high fiber diet like green leafy vegetables,salads, fruits like pears etc and finally you can consult a gastroenterologist to find out if there is any other reason for constipation and if not then he will prescribe you some laxatives to get yuor constipation releived, wishing you good luck Thanks Dr Arshad
