Kidney deficiency can cause dizziness and vomiting in the following two ways: First, deficiency of kidney yin causes lack of nutrients in the brain, according to Chinese medicine, “the brain is the sea of marrow”, and “the kidney is the master of bone and marrow”. Therefore, when kidney yin deficiency is present, dizziness with nausea, vomiting or blurred vision, hair loss, night sweating, memory loss, etc. may occur. Secondly, deficiency of kidney yang causes water transpiration, insufficient gasification, and water-drink stagnation. Because the body’s water metabolism needs to rely on the kidney Yang warmth and transpiration, gasification, like water, need to be underneath the water fire, heating in order to become water vapor. When the fire is not hot enough water cannot turn into water vapor and stops gathering in a certain area. When it stays in the head or in the middle or upper part of the body there will be a failure of clear yang to rise and the pathway for the flow of qi and blood in the brain will be blocked and symptoms such as dizziness and vomiting will occur.
