Can influenza B cause diarrhea?

Generally speaking, "Yi Liu" refers to influenza B, and "La Du Zi" refers to diarrhea. For individuals with weakened immune systems, when the influenza B virus co-infects with other intestinal pathogens, it may cause diarrhea. However, for healthy adults with normal immune systems, if the influenza B virus is limited to respiratory tract infection and does not enter the gastrointestinal tract, it may not cause diarrhea. If any discomfort symptoms occur, timely medical attention is recommended. Detailed analysis is as follows:

For individuals with weakened immune systems, such as the elderly, children, and patients with chronic diseases, influenza B infection may not only cause respiratory symptoms but may also affect the digestive system, leading to symptoms like diarrhea. When the influenza B virus co-infects with other intestinal pathogens, the likelihood of diarrhea increases. Thus, under such circumstances, influenza B can cause diarrhea.

However, for healthy adults with normal immune function, if the influenza B virus remains limited to the respiratory tract and does not spread to the gastrointestinal tract, it may not cause diarrhea. In such cases, the patient's main symptoms may be limited to the respiratory system, such as fever, cough, sore throat, and so on.

To maintain good health, it is recommended to have a balanced diet, maintain appropriate intake, pay attention to bodily reactions, and avoid excessive consumption or eating under unsuitable conditions.
