areola darkening
Introduction
Introduction Blackening of the areola is a common physiological phenomenon in women after adulthood. Generally, after a certain number of couples live in a woman's life, the breast is congested by long-term stimulation, causing melanin deposition, which makes the areola black or brown. However, there is another situation, that is, the influence of genetic factors, some women's areola will be born black.
Cause
Cause
1, baby sucking breast milk
After pregnancy, the change of hormones causes the areola to become larger and darker, even if the postpartum recovery is better, because the hormone changes can not return to the prenatal state.
2, excessive husband and wife life
When the body is stimulated, the local capillaries are stretched and thinned, and the blood oxygen exchange is too late to cause pigmentation and aging. In addition, the melanin gradually precipitates, causing the areola to become black, and the color of the woman's private part is more and more dull.
3, qi stagnation leads
Because women have special processes such as menstruation, belt, birth, and production, the burden in daily life is heavy. The dual stress of shouldering work and family is often more vulnerable to wind, cold, department, heat and other evils than other people. Air-conditioning disorders, coupled with women's sensitivity, mood is not very stable, excessive thinking and other disturbances inside the body's internal blood and blood, more likely to lead to private parts to black.
4, genetic
Because of the genetic factors of the mother or grandmother, the private part will also turn black.
After pregnancy, the change of hormones causes the areola to become larger and darker, even if the postpartum recovery is better, because the hormone changes can not return to the prenatal state.

Diagnosis
Differential diagnosis
Need to be distinguished from melanin, melanin is a common symptom of many diseases, need to go to the hospital for diagnosis and treatment.
1. Endocrine diseases: due to excessive melanocyte stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH), such as Addison's disease, Cushing's disease, Nelson's syndrome, ovarian tumor, malignant pheochromocytoma, and long-term Treated with ACTH. During pregnancy, the use of estrogen and estrogen-containing contraceptives is also more common in melanin pigmentation.
2, metabolic diseases: such as hemochromatosis, allergic dermatitis of various types of porphyria, hepatolenticular degeneration, skin amyloidosis, high snow disease and other symptoms of melanin deposition.
3, nutritional diseases: melanin deposition will have vitamin A deficiency, vitamin B12, vitamin C, folic acid, niacin and other lack, malabsorption syndrome.
4, chronic infections: such as malaria, kala-azar, schistosomiasis.
5, tumor: seen in the production of ectopic ACTH and MSH tumors, such as lung cancer, pancreatic cancer, advanced malignant melanoma, advanced cancer of the cancer. Melanosis is occasionally seen in Hodgkin's disease, lymphosarcoma, and chronic lymphocytic leukemia.
6, connective tissue diseases: can be found in rheumatoid arthritis, still disease, generalized scleroderma, dermatomyositis, systemic lupus erythematosus.
7, drug-induced melanin deposition: seen in long-term use of chloroquine or hydroxychloroquine, chlorpromazine, butyl sulfonate (busulfan), nitrogen mustard, cyclophosphamide, arsenic, antimony, lead and so on.
8, skin lesions melanin deposition: skin acute and chronic infection, acanthosis nigricans, Riehl (Riehl) melanosis, tar black disease and reticular pigmented skin heterochromia.
9, other: chronic liver disease, cirrhosis, chronic renal insufficiency, Whipple disease and other melanin deposition phenomenon.
