Hyperthyroidism
Hyperthyroidism is a state in which the thyroid gland makes too much thyroid hormone. The body runs fast: weight loss, a racing heart, heat intolerance, loose stools, poor sleep, and anxiety.
Cycles change with it. In a series of 214 women with an overactive thyroid, 21.5 percent had a cycle disturbance, against 8.4 percent of women without thyroid disease.1 Periods tend to come less often, and cycles without ovulation are common.2
Clinicians check thyroid levels when cycles change or conception does not happen. When thyroid levels come back to normal, the cycle often follows.
