Diarrhea is a common digestive complaint characterized by frequent, loose, and watery stools. Though it is a symptom of many illnesses, it is not itself a disease. The terms “diarrhea” and “diarrhoea” are both correct spellings, and there is no difference between the two.
Diarrhea is caused by a variety of factors, including viral or bacterial infections, food intolerance, food poisoning, stress, or medications. It is also a side effect of some medical treatments, such as chemotherapy or radiation therapy. Eating certain foods, such as dairy, can also cause diarrhea in some people.
Diarrhea is generally treated by replenishing fluids and electrolytes lost due to the frequent and watery stools. This can be done with oral rehydration solutions or over-the-counter medications. In some cases, antidiarrheal medications, such as loperamide, may be used to slow down the frequency of the stools.
In most cases, diarrhea can be treated at home with adequate hydration and rest. However, if the diarrhea persists for more than a few days, or if it is accompanied by severe abdominal pain or bloody stools, it is important to see a doctor to rule out serious illnesses, such as food poisoning or a bacterial infection.
