Causes for a two-week long period include uterine fibroids or polyps, endometriosis or pelvic inflammatory disease, according to EmpowHER. In women over the age of 45, long periods can indicate the beginning of menopause, while in women of child-bearing age they can indicate hormonal imbalances due to changing contraception or using a copper IUD. If pregnancy is a possibility, a prolonged period may indicate a miscarriage.
In cases of continual two-week long periods, a pelvic examination, ultrasound and biopsy of tissues can be conducted to determine the cause of the prolonged bleeding, according to EmpowHER. In women reaching middle age, a practitioner sometimes chooses to wait and see if the prolonged periods correct themselves without further treatment as they are often caused by menopause or changing hormone levels.
In the case of uterine fibroids and polyps, they are surgically removed to prevent excessive bleeding, according to EmpowHER. In some cases, hormonal imbalances that cause excessive bleeding are treated using oral contraceptives, anti-inflammatory medications or hormone replacement therapy. Switching from a copper IUD to a hormonal one can also eliminate excessive bleeding if that is the cause. In some women, nutritional supplementation is necessary to make up for nutrient loss from prolonged menstrual bleeding.
