What causes vomiting and diarrhea during summer?

Generally, vomiting and diarrhea during summer may be caused by improper diet or heatstroke, or could be due to acute gastroenteritis. If discomfort occurs, it is recommended to seek medical attention promptly.

1. Improper Diet

Vomiting and diarrhea in summer may result from excessive heat, frequently consuming cold foods such as ice cream, chilled watermelon, or iced beer, which can irritate the gastrointestinal tract. This may also be accompanied by symptoms such as abdominal pain, bloating, and nausea.

2. Heatstroke

This may occur when high ambient temperatures cause prolonged exposure to hot environments, leading to dysfunction of the body's temperature regulation center and preventing timely dissipation of excess heat, resulting in heatstroke. Symptoms may include fatigue, acid reflux, heartburn, excessive sweating, and abdominal pain.

3. Acute Gastroenteritis

High summer temperatures can cause food spoilage. Consuming contaminated food may lead to bacterial or viral infections, or overeating, especially high-fat foods, may trigger acute gastroenteritis. Symptoms may include fever and abdominal pain. Severe cases may lead to dehydration, electrolyte imbalances, or even shock.

In daily life, maintain healthy habits and avoid spicy or irritating foods such as Sichuan pepper, chili peppers, and garlic, as they may hinder recovery.
