3. Menstrual Changes
Another unpleasant consequence of hyperthyroidism is menstrual changes. Naturally, only females are affected by this symptom. If you experience very early or very late menstruation, you should be evaluated for possible thyroid problems. Moreover, any changes to menstrual pattern – having more or less frequent periods – is a cause for concern. You should also evaluate the amount of menstrual flow, as this can be affected by hyperthyroidism. In some cases, your period may last for more than a week; it may also last for only a few days. In any case, it’s important to be evaluated by your physician.
