Under what circumstances will menstruation be delayed?

Many female friends have encountered the situation where their menstruation is suddenly delayed, but they can't find out what causes the delay. In fact, there are many reasons for the delay of menstruation, and most of them are relatively normal physiological phenomena. Now the editor will give you a detailed introduction. Only by understanding it clearly can we help you regulate it.

1. Pregnancy

You can use the "Early Pregnancy Test Strip" to test your urine 7 days after your period is delayed. If the result is positive, you are very likely pregnant. If the result is negative, then vice versa. But if you are pregnant, there will be other symptoms such as nausea, breast tenderness, etc. Of course, the last resort is to go to the hospital for an ultrasound examination.

2. The effect of the drug

Endocrine disorders after long-term use of contraceptives can also cause delayed menstruation. Doctors also found, based on patient feedback, that a new generation of gastrokinetic drug, metoclopramide, also known as domperidone, may also cause this condition. Since metoclopramide does not easily cross the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. Central dopamine receptors are inhibited, resulting in a decrease in the amount of hypothalamic release factors entering the anterior pituitary. As a result, the anterior pituitary secretes less gonadal hormones and corticotropin, leading to amenorrhea and delayed ovulation.

3. Caused by surgery

Intrauterine surgery can cause cervical adhesions, which can lead to menstrual blood stasis and thus delay menstruation.

4. Others

Psychological factors such as mental tension, stress, environmental changes, and some diseases that affect the endocrine system can all cause delayed menstruation.

The above reasons are only part of the reasons that lead to delayed menstruation, so there are still many possible reasons. If you are very worried, it is best to go to the hospital for an examination in time to find out the cause. It is also best to develop good living habits in normal times.
