What causes nausea in high temperatures?

  Nausea and vomiting in high temperatures may be caused by heatstroke, gastrointestinal viral infection (gastroenteritis), chronic superficial gastritis, hyperthyroidism, food poisoning, or other reasons. It is important to seek timely medical evaluation and an accurate diagnosis at a hospital.

  1. Heatstroke: Prolonged activity in high-temperature environments can lead to excessive internal heat production, inadequate heat dissipation, and significant fluid loss, increasing the risk of heatstroke. Symptoms may include nausea, vomiting, dizziness, and headache. It is essential to immediately leave the hot environment and increase fluid intake to replenish lost water. Under medical guidance, medications such as Huoxiang Zhengqi Water, Shidi Shui, or Suhexiang Pills may be used to relieve heat and promote cooling.

  2. Gastroenteritis (Gastrointestinal-type cold): Consuming large amounts of cold beverages in hot weather may trigger gastroenteritis, leading to symptoms such as nausea, vomiting, abdominal pain, diarrhea, and fatigue. As directed by a physician, medications like Huoxiang Zhengqi Oral Liquid, Tiaowei Xiaozhi Pills, or Wushi Cha Granules may be taken to resolve dampness, regulate the stomach, dispel wind, and relieve exterior symptoms.

  3. Chronic Superficial Gastritis: In hot conditions, emotional irritability may trigger flare-ups of chronic superficial gastritis. Patients may feel bloated or sense undigested food in the stomach, accompanied by abdominal pain, distension, nausea, vomiting, and reduced appetite. Follow medical advice to take medications such as Bismuth Potassium Citrate Tablets, Sucralfate Chewable Tablets, or Hydrotalcite Chewable Tablets, which help protect the gastric mucosa.

  4. Hyperthyroidism

  Excessive secretion of thyroid hormones leads to overactivation of the sympathetic nervous system and increased gastrointestinal motility, resulting in symptoms such as nausea, vomiting, palpitations, and discomfort. Under a doctor’s supervision, medications such as Propylthiouracil Tablets, Methimazole Tablets, or Carbimazole Tablets may be prescribed to suppress thyroid hormone production.

  5. Food Poisoning

  Consumption of contaminated food can cause food poisoning; the toxins produced may damage the central nervous system, leading to dizziness, nausea, vomiting, and sometimes abdominal pain. Under medical guidance, antispasmodic and analgesic medications such as Belladonna Tablets, Atropine Sulfate Tablets, or Raceanisodamine Tablets may be used to relieve symptoms.

  It is recommended to seek prompt medical attention for accurate diagnosis and appropriate treatment under a physician's supervision. During treatment, consuming water-rich fruits and vegetables may help alleviate discomfort.
