What causes a burning sensation inside the body?

Under normal circumstances, a burning sensation in the body may be caused by physiological factors, fever, internal heat due to yin deficiency, liver and kidney deficiency, or hyperthyroidism. A detailed analysis is as follows:

1. Physiological factors

A feeling of bodily heat can occur due to emotional stress, excessive alcohol consumption, intense physical activity, hot weather, or eating spicy and hot foods. In such cases, there are usually no other discomfort symptoms, and the sensation is short-lived. This is considered a normal physiological phenomenon that does not require treatment.

2. Fever

A common pathological cause of body heat is fever. Fever occurs when pyrogens such as bacteria or viruses stimulate the body's temperature regulation center, leading to a sensation of heat. The primary symptom is elevated body temperature. Drinking plenty of water is recommended, as it promotes blood circulation, accelerates toxin elimination, and helps lower body temperature through sweating and urination.

3. Internal Heat Due to Yin Deficiency

Internal heat caused by yin deficiency is often triggered by external pathogenic factors or irregular diet, and may also result from poor emotional state. Symptoms may include dry mouth and throat, high fever, and flushed face. Under medical guidance, patients may take medications such as Jingxin Oral Liquid or Tianwang Buxin Dan for treatment.

4. Liver and Kidney Deficiency

Liver and kidney deficiency is typically caused by emotional imbalance or excessive fatigue. It may lead to impaired liver function and abnormal liver qi regulation, resulting in excessive internal heat. Under a doctor’s guidance, patients may take medications such as Qiju Dihuang Pills or Liuwei Dihuang Pills for treatment.

5. Hyperthyroidism

Patients with hyperthyroidism have an accelerated metabolism, which generates excess heat, causing a persistent sensation of body heat. This condition is often accompanied by irritability, palpitations, and weight loss. Under medical supervision, patients may use medications such as Propylthiouracil Tablets or Methylthiouracil Tablets for treatment.

Patients should visit a hospital for examination and receive appropriate treatment based on the underlying cause.
