Three stools a day is normal as long as the stools are normal in nature and color and there is no blood or mucus. The normal frequency of stools is 1~3 times a day of formed yellow or dark yellow soft stools. Whether the stool is normal or not needs to pay attention to not only the frequency of stool but also its nature, color and whether it is accompanied by mucus, blood and so on. 1. Frequency: Consider diarrhea if the stools occur more than 3 times a day; consider constipation if the stools occur once every 3 days or twice a week. 2. Nature: If the stools are watery, egg yolk soup-like, etc., consider diarrhea; if the stools are dry and hard to come out, consider constipation. 3. Color: if eating animal blood products, gastrointestinal bleeding, etc., the stool can be black or blood; if the liver and gallbladder obstruction disease can have white stools. 4. Whether there are accompanying substances: if accompanied by mucus, blood, pus and other conditions need to be considered acute enteritis, ulcerative colitis, dyspepsia and other diseases. Whether 3 times a day is normal or not, it is recommended to consult a doctor for examination.
