If urea is low, you can eat more protein-rich foods, such as meat, dairy, eggs and soy products. Urea is an indicator of kidney function. Elevated urea is of great clinical significance and indicates kidney failure. A decrease in urea is not of great clinical significance and is not of great concern in clinical practice. If the decrease is more obvious, it suggests that it may be very much related to the low intake of protein, and protein-rich food is mainly eggs, duck eggs, goose eggs, lean meat, soybean products, fish, etc. Therefore, for patients with low urea, it is recommended that they can eat more of these foods. In addition, the low urea of some patients is very much related to special periods, such as women during pregnancy, because the size of the kidneys increases, the detoxification ability of the kidneys increases, so the removal of toxins will also increase. Urea, in turn, is a typical representative of toxins and therefore also decreases. This condition does not require special treatment and will naturally improve after this period.
