Which is more serious, yellow or white?

There is no such thing as “which is more serious, yellow or white”. There is no such thing as “yellow under the belt or white under the belt”. Yellow under the belt and white under the belt represent different types of illnesses, and there is no one more serious type of illness that needs to be treated. Yellow under the belt is mostly caused by dampness-heat injection (dampness and heat invading the intestines, bladder, vagina, lower limbs, etc.) or dampness-toxin accumulation, which manifests as abundant, yellow-colored, sticky, foul-smelling, often accompanied by vaginal itching, yellow urine, etc. The white under the belt is mostly caused by the spleen and kidney. The whiteness under the belt is mostly caused by deficiency of yang of spleen and kidney (deficiency of yang qi of spleen and kidney), and cold and dampness injection, which is manifested as abundant and whitish color under the belt, thin and clear like snot, accompanied by lack of breath and weakness, and unshaped stools. There is no such thing as which is more serious, yellow or white, and both need to be treated with medicines that are tailored to the specific type of symptoms. There may be other reasons for the yellow or white color, if the symptoms are serious, or if the symptoms do not get better, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then under the guidance of the doctor to give targeted treatment or therapy.
