Gastrointestinal flu is a self-limiting disease and it is recommended to drink more water to facilitate recovery. Of course, if there are obvious symptoms of diarrhea, you can also prepare your own probiotic oral treatment, such as oral Clostridium typhimurium tablets or Bacillus subtilis capsules, etc., the specific medication need to check the drug instructions or consult the clinical pharmacist. It is advisable to consult a specialist for any medication used to treat gastroenteritis during breastfeeding.
