The practitioners use of shared instruments is thought to aid the transmission of hepatitis B, hepatitis C and HIV, although no epidemiological studies have shown this. Long term
Late complications vary depending on the type of FGM. They include the formation of scars and keloids that lead to strictures and obstruction, epidermoid cysts that may become infected, and neuroma formation (growth of nerve tissue) involving nerves that supplied the clitoris. An infibulated girl may be left with an opening as small as 2–3 mm, which can cause prolonged, drop-by-drop urination, pain while urinating, and a feeling of needing to urinate all the time. Urine may collect underneath the scar, leaving the area under the skin constantly wet, which can lead to infection and the formation of small stones. The opening is larger in women who are sexually active or have given birth by vaginal delivery, but the urethra opening may still be obstructed by scar tissue. Vesicovaginal or rectovaginal fistulae can develop (holes that allow urine or faeces to seep into the vagina). This and other damage to the urethra and bladder can lead to infections and incontinence, pain during sexual intercourse and infertility.Painful periods are common because of the obstruction to the menstrual flow, and blood can stagnate in the vagina and uterus. Complete obstruction of the vagina can result in hematocolpos and hematometra (where the vagina and uterus fill with menstrual blood). The swelling of the abdomen and lack of menstruation can resemble pregnancy.
Allergies, also known as allergic diseases, refer a number of conditions caused by the hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, coughing, a runny nose, shortness of breath, or swelling. Note: food intolerances and food poisoning are separate conditions.Common allergens include pollen and certain foods. Metals and other substances may also cause such problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the bodys immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. Diagnosis is typically based on a persons medical history. Further testing of the skin or blood may be useful in certain cases. Positive tests, however, may not necessarily mean there is a significant allergy to the substance in question.Early exposure of children to potential allergens may be protective. Treatments for allergies include avoidance of known allergens and the use of medications such as steroids and antihistamines. In severe reactions, injectable adrenalin (epinephrine) is recommended. Allergen immunotherapy, which gradually exposes people to larger and larger amounts of allergen, is useful for some types of allergies such as hay fever and reactions to insect bites. Its use in food allergies is unclear.Allergies are common.
