When fever is present, diarrhea is generally not able to guarantee the reduction of fever, and is related to the idea of traditional Chinese medicine. When fever has the actual evidence of Yang Ming internal organs of the gastrointestinal tract, it makes the stool particularly dry, and even has the manifestation of heat knots and side currents, and only diarrhea and water. Letting the stool out through diarrhea can assist in this reduction of body temperature, which, clinically speaking, occurs less often. In the case of fever, the relevant examination and diagnosis will be carried out in the hospital, and the treatment is relatively timely, so as not to reach such a serious situation as Yang Ming internal organs. It is very rare to see diarrhea to lower the body temperature when you have a fever. If you want to reduce fever, take oral ibuprofen and other antipyretic drugs or take other methods, and do not rashly take the way to pass stool to reduce fever.
