Will applying too much lipstick really cause the body to absorb too much pigment and dye the urine red?

Although theoretically speaking, the pigments in lipstick can indeed enter the bloodstream through the skin of the lips, be metabolized by the human body and then enter the urine, the skin area of the lips is very small, and the possibility of direct hematuria due to lipstick applied on the surface of the lips becomes Very little. However, it is worth noting that lipstick and other cosmetics not only contain pigments, but also heavy metals such as mercury and lead. Reasonable and normal use can add luster and charm, but excessive use can harm the skin and cause damage to the body.

It is red; when patients with tryptophan metabolism abnormalities, such as Helicobacter pylori infection and congenital tryptophan metabolism abnormalities, blue urine may appear; patients with filariasis and other causes of chylous reflux disorder may appear The condition of chyluria. Certain urinary tract infections, such as Pseudomonas aeruginosa, may cause urine to appear light green or yellow-green.
Which hematuria should attract attention? Xiu Zichao emphasized that hematuria is a symptom. When hematuria occurs, it often indicates that there is a problem with the body.Common causes of hematuria include urinary system diseases such as urinary tract stones, urinary tract infections, urinary tract tumors, and nephritis; systemic diseases such as thrombocytopenic purpura and systemic lupus erythematosus; long-term oral anticoagulant drugs are also common in some elderly people.
