Introduction
In general, whether kidney deficiency causes yellow urine depends on the specific type. In the case of kidney yin deficiency, yellow urine may occur; however, kidney yang deficiency typically does not lead to yellow urine. To maintain kidney health, it is important to maintain a regular sleep schedule and avoid staying up late; eat a balanced diet and avoid spicy, stimulating, raw, or cold foods; and engage in appropriate physical exercise.

Generally speaking, whether kidney deficiency can cause yellow urine depends on the specific type. In the case of kidney yin deficiency, yellow urine may occur; however, kidney yang deficiency typically does not lead to yellow urine. Detailed analysis is as follows:

Kidney yin deficiency is often caused by a depletion of body yin fluids. Insufficient yin fluids can cause urine concentration, which may lead to yellow urine. Additionally, symptoms such as soreness and weakness of the lower back and knees, dizziness, tinnitus, insomnia with vivid dreams, tidal fever, and night sweats may also occur. In such cases, nourishing yin and reducing internal heat should be emphasized, and appropriate yin-nourishing foods can be consumed for regulation.

Kidney yang deficiency is primarily caused by insufficient yang energy. A deficiency in yang energy usually affects the body's warming and propelling functions but does not directly cause yellow urine. Common symptoms include cold pain in the lower back and knees, cold intolerance with cold limbs, listlessness, and pale complexion. For kidney yang deficiency, it is important to warm and tonify kidney yang to improve the state of yang deficiency.

To maintain kidney health, it is important to maintain a regular lifestyle and avoid staying up late. Diet should be nutritionally balanced, with reduced intake of spicy, stimulating, raw, and cold foods. At the same time, appropriate physical exercise should be carried out to strengthen physical constitution and reduce adverse effects on kidney function.
