What is the reason for insufficient Qi and blood and deficiency of both Yin and Yang?

Insufficiency of Qi and blood, as well as deficiency of both Yin and Yang, are detrimental to physical health. Therefore, in understanding the causes, we should also pay attention to common examples such as excessive blood loss, spleen and stomach decline, and insufficient diet, which lead to insufficient nutrient absorption, all of which may cause insufficient Qi and blood.

1. Excessive blood loss

Excessive blood loss mainly occurs in women, but not in men. There are relatively few basic examples of blood loss due to trauma, and the most common example is menstrual blood loss. Women have menstruation every month, and if blood is not replenished over time, blood stasis will occur, meridians will be blocked, and the liver will be seriously affected.

2. Spleen and stomach decline

The spleen and stomach are the root of blood. The Yellow Emperor's Classic of Internal Medicine records: "The middle burner receives qi and takes juice, which changes and turns red, and is called blood." The Standards of Diagnosis and Treatment says: "The spleen and stomach are the fathers of qi and blood." The spleen and stomach are powerful and serve as important energy-producing organs in the human body, and they must be nurtured. If the spleen and stomach are damaged, the metabolism will be lost and blood deficiency will occur over time.

3. Do not eat enough

What is meant here is insufficient nutrition in the diet. People who are picky about food on a daily basis are prone to insufficient qi and blood. The liver relies on blood to generate power, and blood produces fluid for the spleen and stomach. "The Laws of Medicine" says: "Eating more can produce blood, eating less can not produce blood." Although this is true, foods that replenish qi and blood are indispensable.

4. Overwork

Serious illness consumes vital energy, and profuse sweating damages yin and yang. Excessive work can easily consume Qi and blood, which can lead to deficiency of both Qi and blood over time. People who work hard for a long time are most likely to suffer from imbalance of yin and yang, which may lead to illness.
