The symptoms of diarrhea are more frequent stools, thinner stools, increased water content, and also undigested food. In severe cases, pus and blood mucus may accompany the symptoms, and there may be fever, a sense of urgency to defecate, anal discomfort or burning sensation, and in severe cases, watery stools. Some patients have less food, fatigue, and weakness, which can easily lead to abdominal pain as well as urgency. In general, it is due to irregular diet or long-term eating of spicy food that leads to inflammation of the intestines. If acute diarrhea is treated promptly with medication, it can recover in about a week. If chronic inflammation of the intestine is produced, the treatment is longer and the recovery period is usually more than four weeks. The symptoms of diarrhea should be treated promptly, and in serious cases, a colonoscopy should be done to confirm the diagnosis and then treat the symptoms.
