Can hyperthyroidism cause irregular menstruation?

I believe that many people will encounter the problem of hyperthyroidism in their lives. In fact, hyperthyroidism is not as terrible as everyone imagines. It is just a relatively common disease, but there are many symptoms caused by hyperthyroidism. For example, after the onset of hyperthyroidism, patients usually experience symptoms of irritability, physical fatigue, fear of cold and heat, in addition to this, it is accompanied by irregular menstruation, which leads to infrequent menstruation in women and causes uneven hormones.

Can hyperthyroidism cause irregular menstruation?

Hyperthyroidism can cause menstrual irregularities, which mainly manifest as infrequent menstruation in women. Hyperthyroidism is mainly due to thyrotoxicosis caused by excessive secretion of thyroid glands and thyroid hormones. In terms of clinical manifestations, the severity of its symptoms and physical signs are related to factors such as the length of medical history, the degree of hormone elevation, and the patient's age.

The main symptoms are irritability, restlessness, insomnia, palpitations, fatigue, heat intolerance, sweating, weight loss, increased appetite, increased bowel movements or diarrhea, which may be accompanied by periodic paralysis and progressive weakness and atrophy of proximal muscles.

There are two main types of eye manifestations:

The first type is simple exophthalmos, the cause of which is related to the increased sympathetic nerve excitability caused by thyrotoxicosis.

The other type is infiltrative exophthalmos, the cause of which is mainly related to the inflammatory response of orbital tissue. The manifestations of simple exophthalmos are mainly mild protrusion of the eyeball, widening of the palpebral fissure, and reduced blinking, while the infiltrative exophthalmos is more obvious in terms of eyeball protrusion.

Hormones cause menstrual irregularities

Hormones do cause menstrual irregularities clinically. The most common ones are due to endocrine diseases, including abnormal thyroid hormone levels, abnormal glucocorticoid levels, and abnormal prolactin levels, all of which can lead to irregular menstruation.

To put it simply, when there is hyperprolactinemia, the high level of prolactin in the blood will lead to a series of clinical manifestations related to fertility and menstruation, including amenorrhea, scanty menstruation, unstable menstrual cycle, and no ovulation.

Abnormal thyroid hormone levels, for example, in patients with hyperthyroidism or hypothyroidism, in patients with hypothyroidism and hyperthyroidism, if not treated in time and hyperthyroidism and hypothyroidism are not controlled, it may also cause irregular menstruation.

Excessive secretion of glucocorticoids is caused by various adrenal diseases, which may also be one of the causes of menstrual disorders.
