Why Does High Fever Easily Cause Tongue and Mouth Sores?

1. Stomatitis usually refers to oral ulcers. No studies have shown that high fever can cause oral ulcers. High fever is only a sign induced by illness and does not cause damage to oral mucosa.

2. Based on different body temperatures during fever, it is clinically divided into four stages: low fever, moderate fever, high fever, and hyperpyrexia. If the patient's body temperature exceeds 39°C but is within the range of 39°C to 40°C, it is considered high fever. It is not a disease itself but a sign of various diseases that lead to increased heat production and decreased heat dissipation in the body. It is commonly seen in various infectious diseases such as respiratory infections, digestive tract infections, and urinary tract infections.

3. Normally, high fever does not cause damage to oral mucosa or other organ mucosae and has no essential relationship with the onset of oral ulcers. If oral ulcers occur during high fever, it should be considered related to factors such as local trauma, vitamin deficiency, and oral bacterial infections. If blisters develop into ulcers accompanied by signs of high fever, it may be related to oral viral infectious diseases such as oral herpes simplex, chickenpox, and hand, foot, and mouth disease.

4. It is recommended to seek medical attention first to identify the specific cause of high fever and then choose an appropriate treatment plan based on the symptoms. At the same time, personal life care for patients should be enhanced, such as short-term bed rest, drinking more warm water, and consuming light, easy-to-digest liquid or semi-liquid foods.
