Urea nitrogen is basically determined by the balance of urea production and excretion, so it is closely related to protein intake, protein metabolic function and renal function. Therefore, if this value usually exceeds 50mg/dl, it is likely to be renal failure. Simple increase of urea nitrogen can be caused by excessive intake of protein food in dietotherapy. Changing the diet structure and balancing the collocation of protein, sugary food and vegetables will soon return to normal. But if it is not simply urea nitrogen, it is necessary to know whether the kidneys are working normally. View original post >>
