Connecting amenorrhea to your symptoms

Record the date of your last menstrual period and the cycles of the preceding six months

Please specify the date you last started a normal period, the interval between periods before that, and whether there was only light spotting. The date and result of pregnancy tests, contraceptive methods, and the timing of childbirth, breastfeeding, or medication changes are also necessary to interpret the sequence of the cessation of menstruation.

The cause is not determined by weight and exercise alone

While checking recent weight changes, food intake, exercise intensity, stress, and sleep, we also look for changes such as acne, hirsutism, galactorrhea, sensitivity to heat or cold, and pelvic pain. Necessary tests and ultrasounds are determined based on age, pregnancy plans, and accompanying symptoms.

Herbal medicine treatment goals vary depending on the cause of amenorrhea and pregnancy plans

In Korean medicine treatment, we examine how the duration of the cessation of menstruation overlaps with weight, diet, exercise, cold/heat sensitivity, sleep, digestion, acne, hirsutism, flushing, and loss of energy. While continuing treatment for confirmed causes such as nutritional deficiency, over-exercise, PCOS, thyroid/prolactin issues, or ovarian function, we plan herbal medicine treatment by deciding whether to prioritize cycle recovery, sleep, digestion, or energy. After treatment, we monitor not only the presence of menstruation but also pre-menstrual changes, stability of weight and intake, sleep, heat sensations, and the test schedule.

Frequently Asked Questions

Frequently asked questions regarding amenorrhea

If the pregnancy test is negative, can I wait longer?

Check if the test was taken too early; if menstruation has stopped longer than usual, other causes are evaluated. If there is severe pelvic pain or bleeding, seek medical evaluation sooner.

Is the only goal of treatment to induce menstruation?

It depends on the cause and pregnancy plans. In addition to cycle recovery, bone health, endometrial protection, metabolic status, and fertility planning are considered together.
