Skin yellowing without itching and hepatobiliary disease
Introduction
Introduction Skin yellowing without itching and without liver and gallbladder disease is also called "pseudo-jaundice". "Pseudo-jaundice" is not the "true jaundice" caused by the increase of serum bilirubin, but is caused by the increase of serum carotene, which is marked by yellow pigmentation, but no itching, no hepatobiliary disease, serum bilirubin. A type of pathological manifestation characterized by normal and elevated serum beta-carotene. The cause of "pseudo-jaundice" is mainly due to a large or continuous intake of foods containing a large amount of carotene, resulting in a significant increase in serum -carotene and deposition in the subcutaneous tissue resulting in yellowing of the skin.
Cause
Cause
The cause of "pseudo-jaundice" is mainly due to a large or continuous intake of foods containing a large amount of carotene, resulting in a significant increase in serum -carotene and deposition in the subcutaneous tissue resulting in yellowing of the skin.
Medical nutritionists point out that carrots, citrus, and sweet potatoes are rich in carotene. In addition, pumpkins, potatoes, papayas, corn, tomatoes, and peppers are also rich in carotene. Most of these foods are mature crops in the fall and are the foods that people often eat in the fall. Therefore, "pseudo-jaundice" mainly occurs in the autumn, accounting for more than 2/3 of the total number of cases in the whole year.

Autumn is the high season of pseudo-jaundice and the main season for the prevention and treatment of pseudo-jaundice. The difference between "pseudo-jaundice" and "true jaundice" is that "pseudo-jaundice" has no yellow staining of sclera and mucous membranes, but yellow staining of the skin of the palms, soles and ears is very obvious. Lighter, generally in good condition, with no loss of appetite and other discomfort, more than 250 micrograms of beta-carotene per 100 milliliters of serum. "True jaundice" has obvious yellow staining of the sclera and mucous membrane, and often accompanied by pain or discomfort in the upper right abdomen, itchy skin, loss of appetite and nausea and vomiting, serum bilirubin is significantly increased.
Diagnosis
Differential diagnosis
Should be differentiated from the diagnosis of jaundice, jaundice, also known as jaundice, commonly known as yellow disease, is a phenomenon of yellowing of the skin, mucous membranes and sclera caused by the increase of bilirubin concentration in human blood. Certain liver diseases, gallbladder diseases, and blood diseases often cause symptoms of jaundice. Usually, when the blood bilirubin concentration is higher than 2-3 mg/dL, these parts will have a color that can be discerned by the naked eye.
