The constant change in bowel movement (diarrhea or constipation) should raise concern for you. While diarrhea includes the passage of more frequent watery chairs than usual, constipation refers to the presence of a chair less than three times a week, and causes difficulties in the passage of feces.
Diarrhea develops with infections along with nutritional intolerances, and this occurs as a symptom of IBS (irritable bowel syndrome) and MIC (inflammatory bowel disease). Constipation develops from the diet factors, as well as dehydration and intestinal blockage. A sign of trouble is when (sudden) diarrhea persists in one day (without gastric infection), and constipation continues in three days, especially if you feel pain or noticed blood in the stool.
