What causes diarrhea in babies in summer?

Due to the hot weather in summer, gastrointestinal diseases are very likely to occur. Especially for babies, whose gastrointestinal function is not yet fully developed, it is easy for them to have diarrhea in summer. So what are the reasons for this phenomenon?

1. Gastroenteritis: Gastroenteritis (also called stomach flu) is an inflammation of the stomach and intestines that can cause diarrhea in infants, children, and adults. Gastroenteritis is very common and can be caused by many different viruses. The most common pathogen is rotavirus. Half of the children hospitalized for diarrhea are infected with this virus, which occurs most frequently in late autumn and early winter.

2. Bacterial infection: severe diarrhea (sometimes accompanied by vomiting), abdominal pain, bloody stools, and fever are often caused by viruses or bacteria (E. coli, Salmonella, etc.). Some of these infections are self-healing, but some can be very serious, such as those caused by E. coli in undercooked meat.

3. Parasites: Parasitic infections may also cause diarrhea. For example, giardiasis (also called giardiasis) is caused by a microscopic parasite that lives in the intestines. Parasites are easily spread when living in groups and require special medications to treat. Parasites mainly enter the baby's body through drinking water (including water used to make formula milk). Tap water is stored and transported through rooftop water tanks and water pipes, which can easily cause secondary pollution and contain various parasites such as red worms and Giardia lamblia.

4. Antibiotics: If your baby develops diarrhea during or after antibiotic treatment, it may be related to the medicine.

5. Food factors: Drinking too much fruit juice (especially fruit juice containing sorbitol and high concentration of fructose) or too many sugary drinks may also make your baby's stomach uncomfortable and his stool become loose.
