Is it normal to have a 40 day long menstrual cycle?

How many days is a normal menstrual cycle? Many women are very concerned about this issue. There is no specific number of days in the menstrual cycle. As long as the cycle is normal, there is no need to worry. Is a 40-day menstrual cycle normal? Let’s find out together.

Is a 40-day menstrual cycle normal?

Experts point out that everyone's menstrual cycle is different, but as long as the cycle time is not very different, it is normal. Some people have a period every 20 days, and some people have a period every 40 days. As long as the intervals are similar, there is no need to worry.

If your cycle length increases shortly after your first menstrual period and remains the same until now, then there is no big problem. Some women even have their menstrual period only once every three months. But if you have only recently noticed an increase in your period time and you feel unwell, you should go to the hospital for a check-up.

Of course, Chinese medicine also has its own set of systematic theories: Chinese medicine believes that the reasons for a woman's prolonged menstruation can be divided into real and false, so regulating menstruation must first distinguish between real and false. Most of the empirical studies show that this is due to blood stasis blocking the Chong and Ren meridians, preventing new blood from returning to the meridians; most of the deficiency studies show that this is due to yin deficiency and excessive fire, which shakes the blood sea and leads to prolonged menstruation. In addition, Chinese medicine treatment emphasizes overall observation of the complexion, and whether a woman has menstrual irregularities can also be observed from her complexion. This is not because Chinese medicine can read faces, but because Chinese medicine believes that when the internal organs and blood change, they are reflected on the face.

1. Yin deficiency and hyperactivity of fire: If a woman has a Yin deficiency constitution, or has been depleted of Yin fluid due to illness for a long time, given birth too many times, or had excessive sexual intercourse, her body will suffer from Yin and blood depletion. Yin deficiency and excessive fire cause blood to be restless, and menstruation cannot function normally, resulting in prolonged menstruation.

2. Qi deficiency and blood stasis: If a woman is usually depressed, it will lead to Qi deficiency and blood stasis over time. Or women may be affected by dampness during their menstrual period or after giving birth, which can block the circulation of blood and qi and cause blood stasis. Because blood stasis blocks the uterine vessels, new blood cannot return to the menstruation, resulting in continuous delay of menstruation.

Generally speaking, if it is always 40 days, there is no need to worry too much, but if the cycle is unstable, you need to check it as soon as possible.

Causes of long menstrual cycles

The normal menstrual cycle is 22-35 days, with an average of 28 days. Generally speaking, it is normal for menstruation to be advanced or delayed by about a week.

There are many factors that cause the prolongation of the menstrual cycle, which can be divided into the following categories: abnormalities in the nerve center - hypothalamus-pituitary gland; pituitary abnormalities refer to pituitary gland diseases that cause abnormal gonadotropin secretion, which can be congenital or acquired; uterine and ovarian abnormalities are due to congenital dysplasia of the uterus and ovaries or ovarian abnormalities or secondary diseases that cause irregular menstruation. The actual reasons may be:

1. Endometriosis: This is often caused by affecting the contraction of the uterine muscle layer or due to the increase of the endometrium, resulting in excessive menstrual cycles or prolonged menstruation. Insertion of an IUD can also cause prolonged menstruation.

2. Uterine leiomyoma: Especially uterine and cervical leiomyoma, due to the expansion of the total area of ​​the uterine body and abnormal contraction, it can cause excessive menstrual cycles and prolonged menstruation.

3. Bleeding due to uterine imbalance: such as anovulatory male sexual dysfunction, abnormal uterine bleeding and irregular uterine wall shedding, all of which are caused by endocrine function problems and lead to prolonged menstruation.

4. Chronic uterine hypertrophy: Due to pelvic congestion, the estrogen level of the uterus and ovaries continues to increase, causing hypertrophy of the uterine muscle layer, resulting in excessive menstrual cycles and prolonged menstruation.

Pelvic inflammation, intrauterine polyps, uterine inflammation, etc. are all caused by poor intrauterine blood circulation, atrophy and necrosis or pelvic congestion, which lead to excessive menstrual cycles and prolonged menstruation.
