I don't know, but since your question has been here for several months, without ever getting an answer, I suggest you try posting on WebMD to see if someone there can help you. Here's their link: http://www.webmd.com/ Good luck!

If I had such a condition, I would want to collect some samples and present them to a friendly chemist at a university for a pro bono analysis, for purposes of a learning experience in stoichiometry. If the neice were a consumer of voluminous amounts of carrots, or another beta carotene source, her skin would take on a somewhat orange tint and (guessing here) she might also exude some carotene in her perspiration. Carotene (actually an isomer found most commonly in plant and animal tissues)is converted into vitamin A in the liver up to an optimum amount, and the rest must be disposed of in other ways. An excess of beta carotene is not necessarily toxic. Excess vitamin A has been associated with increased incidence of some forms of cancer, while a deficiency of it has, also. Somehow vitamin A produced from beta carotene by a normal liver does not seem to be associated with this risk; so there is some speculation that it is more healthy to consume beta carotene (and allow one's liver to do the converting of the amount the body needs) rather than to take vitamin A supplements. In any case, only laboratory tests and other diagnostic procedures would confirm if there is a liver malfunction or, possibly, a benign but anomalous liver function (such as in Gilbert Syndrome). Gilbert Syndrome is a normally benign genetic condition (recessive) in which jaundice can be triggered by strenuous exercise and other sources of stress which, themselves, may or may not be pathological. The symptom goes away without treatment. However, any undiagnosed jaundice should be evaluated by a qualified physician. And, again, I know of no definite information concerning unconjugated bilurimin (the jaundice-causing pigment in Gilbert Syndrome) being exuded in perspiration... pro or con. Some victims of vitiligo (leucoderma) are shy about the fact they use certain compounds to conceal it, and might not mention such a practice to relatives. Females, because they use makeup for cosmetic purposes routinely, do not tend to be as secretive about the use of stains and dyes and artificial sun tanning creams as would males. Some of these products go on clear and then turn dark as they react with chemicals in or on the skin. And these might turn dark, also, where they are rubbed off onto, say, a white collar or pillow case together with chemicals from skin. I am NOT a medical professional. Only a qualified medical doctor should attempt to diagnose or treat a symptom such as your question addresses.

Ho-hum. What website should you try next? Some situations transcend sitting on your duff and typing at a computer. Get her to the friggin doctor!

My daughter sweats orange. Dr's dont know why. Suggested it's iron. My daughter also is recently diagnosed anemic.

I don't know the answer but wondered if there was ever an answer to this. my husband also has this occasionally. Bright, pinkish orange stains underarms and where sweat smears on a white t shirt. For the past year. No tanning lotions or cosmetics used. No symptoms. Thanks

thanks for your prompt response. no, he is not a redhead. wonder how else i could search....
