Why does heatstroke cause vomiting blood?

The causes of hematemesis (vomiting blood) due to heatstroke can be divided into the following points: 1. Gastric mucosal injury: During heatstroke, the body's prolonged exposure to high temperatures may lead to congestion and edema of the gastric mucosa. In severe cases, gastric mucosal damage may occur, resulting in bleeding. 2. Severe vomiting: Patients with heatstroke often experience symptoms such as nausea and vomiting. If vomiting is too frequent or severe, it may further aggravate gastric mucosal damage, leading to bleeding. 3. Dehydration and electrolyte imbalance: During heatstroke, patients lose large amounts of body fluids and electrolytes. If not replenished timely, dehydration and electrolyte imbalance may occur, affecting the normal function of the gastric mucosa and increasing the risk of bleeding. When symptoms of heatstroke occur, timely measures such as cooling and rehydration should be taken. It is important to monitor changes in the patient's condition, and seek medical treatment when necessary.
