Diarrhea after receiving the rotavirus vaccine

Diarrhea refers to loose or watery stools. Diarrhea after receiving the rotavirus vaccine may be caused by side effects of the medication, cold exposure to the abdomen, allergies, or other reasons. The specific causes are analyzed as follows:

1. Side effects of the medication

Receiving the rotavirus vaccine may lead to adverse reactions such as abdominal pain, vomiting, and fever. These are considered normal and generally do not require special treatment.

2. Cold exposure to the abdomen

If the abdomen is not kept warm after vaccination, cold exposure may cause spasms of the smooth muscles in the digestive tract, leading to symptoms such as abdominal pain and diarrhea. Applying a warm towel compress to the abdomen can increase local skin temperature and promote blood circulation, thereby relieving discomfort.

3. Allergic reaction

If an individual is allergic to components in the rotavirus vaccine, an allergic reaction may occur after vaccination, causing symptoms such as skin itching, rash, nausea, and diarrhea. In such cases, medications like loratadine capsules, cetirizine hydrochloride tablets, or fexofenadine hydrochloride tablets may be used under a doctor's guidance.

Besides the above-mentioned causes, diarrhea could also result from gastrointestinal dysfunction, irritable bowel syndrome, chronic gastritis, or other conditions. If symptoms are severe, it is recommended to promptly visit a reputable hospital for diagnosis and treatment under the guidance of a qualified physician to avoid delays in managing the condition.
