Summer Abdominal Pain: Doctor Warns of 5 Hidden Causes, Including Dehydration

Abdominal pain and diarrhea during hot weather might be dismissed as simply eating something bad. However, chest and critical care physician Huang Hsuan warns that summer stomachaches can arise from multiple hidden factors, not just spoiled food.

Huang explained that high temperatures accelerate bacterial growth, making improperly stored leftovers or undercooked seafood a common culprit for gastroenteritis. Additionally, consuming excessive ice cream and cold drinks can intensely stimulate the gastrointestinal tract, leading to sudden pain, bloating, or diarrhea. Viral gastroenteritis, including norovirus and rotavirus, is also active in summer and often accompanied by severe nausea and vomiting.

Dehydration and electrolyte imbalances, caused by excessive sweating without adequate fluid and electrolyte replacement, can significantly disrupt intestinal motility, resulting in dull pain and discomfort. Furthermore, changes in routine due to summer breaks or travel, such as staying up late or irregular eating habits, can trigger irritable bowel syndrome, leading to gastrointestinal distress.

Huang stressed that persistent, severe abdominal pain unresponsive to painkillers, high fever above 38.5°C, bloody or black stools, repeated vomiting, and clear signs of dehydration (dizziness, extreme thirst, reduced urine output) are critical warning signs. Individuals in vulnerable groups like the elderly, young children, or those with compromised immune systems should seek prompt medical attention. If symptoms persist for more than two to three days or if any warning signs appear, it is crucial to consult a doctor.
