I caught a cold and my menstrual flow suddenly decreased.

Some female friends catch a cold during menstruation, which will lead to a decrease in menstrual flow. In fact, this situation is caused by the lower estrogen level due to the cold, which is normal. However, you need to be careful not to catch a cold during menstruation, because this will make it difficult to discharge the dirty blood in the body, which is not good for human health. You must maintain a healthy lifestyle and keep warm.

1. Reasons for less menstruation due to cold

It is a normal physiological phenomenon for patients to experience a decrease in menstrual volume after catching a cold, so there is no need to worry too much. After a woman catches a cold, her body becomes weaker and the estrogen level in her body decreases. Estrogen can stimulate the endometrium to proliferate and thicken in preparation for conception. If conception does not occur, the proliferating endometrium will shed and bleed, forming menstruation. After a cold, the low estrogen level in the body causes the endometrium to not proliferate thick enough, and the menstrual volume will decrease. In addition to colds causing a decrease in menstrual volume, excessive stress, high work and life pressure, and a bad mood can also cause a decrease in menstrual volume.

2. Four common causes of irregular menstruation

"Not coming when it should, but too little when it should be" is irregular menstruation. So-called irregular menstruation means that menstruation does not come according to the normal cycle, but there are actually many different types of irregular menstruation - oligomenorrhea: irregular menstrual bleeding and few times; frequent menstruation: too many times; menorrhagia: too long and too much menstrual bleeding, but the menstrual cycle is regular; oligomenorrhea: very little menstrual bleeding, but the interval between menstrual cycles is normal.

The most common cause of irregular menstruation is hormonal imbalance, while other causes may be caused by organ diseases.

1. Hormone imbalance:

It is the most common cause of uterine bleeding, especially in adolescent girls and menopausal women. Hormonal imbalance causes anovulatory bleeding, which results in irregular menstruation during the first menstruation or near menopause.

It will also cause unlimited growth of the endometrium, until the thickness of the endometrium grows to a level that the uterus cannot bear, causing breakthrough bleeding. Therefore, the amount of menstrual blood is often small and dark brown in the early stages, and will develop into heavy bleeding over time.

2. Difficulty in blood clotting:

For example, people who lack platelets or have leukemia will have coagulation disorders, which will cause them to be unable to stop bleeding on their own after menstruation, resulting in heavy menstrual flow.

3. Thyroid problems:

If the thyroid function is too low or too high, it will cause ovarian dysfunction and irregular menstruation.

4. Poor liver function:

Poor liver function can slow down female hormones, causing endometrial hyperplasia and abnormal bleeding.
