Amenorrhea is one of the most common gynecological diseases, and it usually requires an ultrasound and a sex hormone panel test. Testing the sex hormone panel should be done by drawing blood on an empty stomach in the morning, three to five days after the onset of menstruation, for more accurate results. After identifying the cause, treatment should be targeted accordingly. There are many reasons for amenorrhea in women, such as poor lifestyle habits, excessive fasting for weight loss, malnutrition, and kidney deficiency, all of which can cause this condition. Amenorrhea can lead to disturbances in the ovulation cycle and, in severe cases, prevent the development of follicles, causing infertility in women.
