A mother took her three-year-old child to the hospital to see a doctor The mother was very worried She said that the child's skin had been yellow for several days She went to the Pediatrics for examination It was normal There was no hepatitis or other diseases And the child's self-feeling is also very good, energetic, can eat can sleep, defecate unobstructed The pediatrician later suggested going to the dermatology department The dermatologist found that the skin of the child's face and hands and feet was obviously yellow, but shiny, and the skin of the whole body was also yellow than that of the normal children Combined with the results of liver and kidney function and bilirubin test, it is considered that children have "orange yellow disease", namely, carotenemia The mother of the child said that one week before the onset of the disease, the family went back to their hometown and picked a lot of oranges in the farmhouse, and then ate a lot of oranges in the following days What is carotenemia? Carotenemia is a yellow skin disease caused by the high content of carotene in the blood Human skin color is mainly determined by four factors: heme, carotene, melanin and skin thickness Carotene makes the skin yellow, heme makes the skin red or blue, melanin makes the skin black, the thicker the skin is, the darker it is If you take too much carotene, your skin will turn yellow Infants need extra vitamin A because of their low resistance, and red and yellow fruits and vegetables are a good source of vitamin A, including carrots, pumpkins, sweet potatoes, tomatoes, mangoes, red peppers, etc These red and yellow fruits and vegetables are also rich in carrots and carotenoids, including lycopene, α and β - carotenoids β - carotene is a common food colorant Therefore, infants are more likely to develop carotenemia than adults This jaundice is different from that in which the Yellow carotene makes the skin yellow, which is easily confused with jaundice (hyperbilirubinemia) Different from jaundice, the skin color of carotene is bright orange, and the distribution of sweat glands is more obvious in areas with dense distribution (such as nasolabial groove, palmar center and plantar Center), which will not affect the sclera and mucosa, so the patient's eyes are not yellow Jaundice makes the skin dark yellow, involving the sclera and mucosa, so the patient's eyes are white and yellow Diet is the main cause of children's carotenemia, but some diseases can also lead to this disease, such as liver disease, kidney disease, diabetes, anorexia nervosa, hypothyroidism and so on These diseases make it difficult to convert β - carotene into vitamin A in the body Even if you take a normal amount of carotene, your skin will turn yellow because you can't metabolize it Carotene is the precursor of vitamin A excessive intake of vitamin A may lead to liver poisoning, but carotene will not Got after carotene blood disease, just skin is yellow, need not worry about liver can be poisoned Reduce or stop the intake of related food, skin yellowing will subside and return to normal In addition to infants, adults who eat a lot of red and yellow fruits and vegetables also suffer from carotene Once there was a girl, in order to lose weight, every day with the virgin fruit for dinner, eating a week after the whole body skin yellow This is caused by excessive lycopene intake After three days, the yellow color gradually subsided and returned to normal within one week Things are good, but don't eat too much, too much is not enough.
