What causes hot flashes and night sweats?

The symptoms of hot flashes and night sweats may be caused by various factors. The following are several common causes: 1. **Yin deficiency with hyperactive fire**: This is one of the main causes of hot flashes and night sweats. When the balance between Yin and Yang in the body is disrupted due to insufficient Yin fluids, it can lead to internal generation of heat pathogens, manifesting as symptoms such as night sweats. 2. **Qi and blood deficiency**: Deficiency of Qi and blood may lead to symptoms such as night sweats and hot flashes, which could be related to congenital physical weakness or irregular eating habits. 3. **Hyperthyroidism**: This endocrine disorder is caused by excessive secretion of thyroid hormones and often presents with symptoms such as palpitations, heat intolerance, and excessive sweating. 4. **Menopausal syndrome**: During menopause, women may experience symptoms such as hot flashes and night sweats due to a significant decline in estrogen levels. If these symptoms occur, it is recommended to seek timely medical consultation for professional evaluation to determine the underlying cause and receive appropriate treatment.
