What causes irregular menstruation?

The occurrence of such adverse symptoms as irregular menstruation may first be functional uterine bleeding, or even no menstruation for 2 months; secondly, uterine fibroids can also induce frequent urination at night; luteal insufficiency can easily lead to repeated miscarriages; then, contraceptive rings and medical abortion may induce irregular menstruation.

1. Functional uterine bleeding

There are no obvious organic changes, but it may manifest as endless bleeding or heavy bleeding, mainly manifested by a significant extension of post-menstrual bleeding time. In most cases, the menstrual period lasts about 10 days, and some even 2 months.

2. Uterine fibroids

Uterine fibroids growing in different locations can cause different symptoms, such as long menstrual periods, heavy menstrual flow, increased urination at night, frequent urination, unexplained constipation, or even abdominal lumps.

3. Luteal insufficiency

Usually, the corpus luteum secretes insufficient progesterone after ovulation or the corpus luteum atrophies prematurely, leading to delayed endometrial development, which is called luteal insufficiency. Patients are prone to shortened menstrual cycles, repeated miscarriages or infertility.

4. Impact of IUD

There is generally a six-month adaptation period after the IUD is inserted. It is normal to experience lower abdominal discomfort within 3-6 months after the IUD is inserted. After 7 months, if there is still a feeling of heaviness in the lower abdomen, back pain, vaginal bleeding, and menstrual blood volume exceeding twice the normal level, we should go to see a doctor.

5. Medical abortion

Drugs disrupt the balance of human hormone levels, which may lead to insufficient hormone secretion and hormone disorder. Patients may experience abnormal menstrual cycles, dysmenorrhea, sexual pain, decreased libido and other discomforts.

6. Other factors

In addition to the above reasons, environmental changes, excessive fatigue or mental stress can cause irregular menstruation. Generally, the symptoms can be significantly improved through self-regulation. If the menstruation is irregular for a long time, you should seek medical attention in time.

For women, the adverse symptom of irregular menstruation is quite troublesome. They must go to the hospital for a check-up first to find out the cause, and then regulate their menstruation to stay healthy.
