Signs and symptoms
A woman may have vaginal irritation, itching, or burning or may notice a foul-smelling or abnormal discharge that could appear green or yellow.The following signs or symptoms may indicate the presence of infection:
Irritation or itching of the genital area
inflammation (irritation, redness, and swelling caused by the presence of extra immune cells) of the labia majora, labia minora, or perineal area
vaginal discharge
foul vaginal odor
pain/irritation with sexual intercourse

Complications
Vaginal infections left untreated can lead to further complications, especially for the pregnant woman. For bacterial vaginosis, these include "premature delivery, postpartum infections, clinically apparent and subclinical pelvic inflammatory disease, [as well as] postsurgical complications (after abortion, hysterectomy, caesarian section), increased vulnerability to HIV infection and, possibly, infertility". Studies have also linked trichomoniasis with increased likelihood of acquiring HIV; theories include that "vaginitis increases the number of immune cells at the site of infection, and HIV then infects those immune cells." Other theories suggest that trichomoniasis increases the amount of HIV genital shedding, thereby increasing the risk of transmission to sexual partners. While the exact association between trichomoniasis infection and HIV genital shedding has not been consistently demonstrated, "there is good evidence that TV treatment reduces HIV genital shedding. Five studies were reported in the literature and, of these, four found a decrease in HIV genital shedding after TV treatment.
A retrospective study in Turkey found that the prevalence of Sheehan’s syndrome was directly proportional to the amount of at-home deliveries each decade. This may be due to previously limited obstetric techniques present in a home environment. For example, an area of improvement in preventing the condition could be an increase in the efficacy of treatment to hypovolemic shock through blood transfusion.Pituitary necrosis may directly result from a lack of blood flow in the hypophyseal artery as a result of pituitary gland enlargement during pregnancy. One cause of pituitary growth associated with the risk of Sheehan’s syndrome is the hyperplasia of lactotrophs (responsible for prolactin production). Ischemia may occur as a result of vasospasm, thrombosis, or vascular compression sometimes as a result of an increase in the amount of lactotroph cells throughout gestation (contributing to the enlargement of the pituitary gland). Necrosis may occur as a result of severe hypotension or shock due to excessive uterine bleeding following childbirth. Sheehan’s syndrome may occur as a result of the arterial constriction and abnormal hypotension in conjunction with an insufficiency to meet the increased demand in blood supply of the pituitary gland seen during pregnancy. This increased blood-flow and metabolic demand is associated with the previously mentioned hyperplasia of lactotrophs.Some possible predisposing factors to Sheehan’s syndrome may include: inherited or acquired disseminated blood coagulation (DIC), restriction pituitary blood supply, small sella size, vasospasm, or thrombosis.
