Yin deficiency may cause palpitations and shortness of breath.

Yin deficiency leads to a reduction in body fluids, causing a relative excess of yang energy, which in turn generates internal heat. This heat disturbs the mind, resulting in palpitations. When yin fluids are depleted and unable to nourish the internal organs, organ function declines, including cardiopulmonary function, leading to shortness of breath.

Patients with Yin deficiency may also experience symptoms such as insomnia, excessive dreaming, hot flashes, and night sweats. This is because Yin deficiency leads to excessive Yang, which damages the blood and prevents Yin from restraining Yang, resulting in restless sleep.

Treatment for Yin deficiency should follow the principle of nourishing Yin and tonifying the kidneys. Symptoms can be improved through traditional Chinese medicine or acupuncture, such as using Liuwei Dihuang Wan or Zhibai Dihuang Wan. Patients should maintain emotional stability and avoid overwork to facilitate recovery.
