Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day.[2] It often lasts for a few days and can result in dehydration due to fluid loss.[2] Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour.[2] This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe.[2] Loose but non-watery stools in babies who are exclusively breastfed, however, are normal.[2]
