Why Can The Period Last Longer Than Normal?

The longer than normal period can cause concern in women since it is sometimes an indicator of some pathology or alteration in the reproductive system. Discover its most frequent causes

For many years, menstruation has been a taboo in society. This has caused a great ignorance of the variety and richness that the menstrual cycle implies. So much so that when the period lasts longer than normal, it is always scary, but it doesn’t have to be pathological.

The average duration of bleeding ranges from 4 to 8 days but varies depending on the population studied. However, some women do not meet this criterion, as they have a longer or shorter period than usual. Why can these changes occur? Keep reading to find out.

When is the longer than normal period considered?

First of all, it is necessary to distinguish the type of vaginal bleeding and whether it is linked to menstruation. Depending on the stage of the menstrual cycle in which bleeding occurs, we can rule out whether it is an alteration of the period or not.

To know if menstruation is within normality, we must keep track of our cycle, the duration, and the bleeding. Based on these characteristics, we have different alterations :

  • Eumenorrhea: it is when menstruation has a duration and quantity that places it within the average. That is, it lasts between 4-8 days with a flow of 80 milliliters.
  • Hypermenorrhea: menstrual bleeding occurs in excessive amounts in terms of volume, exceeding 80 milliliters.
  • Polymenorrhea: the duration is excessive, for more than 8 days.
  • Proiomenorrhea: this is an alteration that changes the total days of the cycle, making them short, below 28 days between periods.

Therefore, if we see that the days of bleeding are extended by more than 8, we will be in front of a polymenorrhea. However, this variation is almost always accompanied by excessive bleeding, which changes the medical definition of menorrhagia.

Keeping a monthly check of the days is a useful tool for women who want to know their cycle in-depth.

Causes of a longer than normal period

When a menstrual flow occurs with duration and abundance that is different from the previous ones that we have had, we must go to the gynecologist for a clinical examination. The possible causes of the disorder are divided into two large groups that we will discuss now.

Organic causes

When the cause of a longer-than-normal period can be seen on the physical examination performed by the gynecologist or on complementary tests, such as an ultrasound scan, it means that it is organic. There are several responsible anomalies, such as the following:

  • Iatrogenic: some medical procedure or medication causes a menstrual disturbance. The most common are hormonal contraceptives since they alter the menstrual cycle and the functioning of estrogens and progestins. Also, other iatrogenic causes are psychotropic drugs and antiplatelets.
  • Trauma and presence of foreign bodies in the vaginal canal
  • Infections: they can generate alterations in the structure of the uterus, such as adhesions, which prevent a correct emptying of bleeding. The most frequent are usually those of sexual transmission.
  • Benign or malignant organic pathology: the organ that detaches and causes bleeding is called the endometrium and is a uterus layer. Sometimes, there may be a benign abnormal growth, as is the case with fibroids; or malignant, such as endometrial tumors.

Hormonal causes

On the other hand, there is a group of causes that alter hormonal functioning and impact the entire organism:

  • Hyperestrogenism: in a healthy and normal menstrual cycle, estrogen generates the endometrium’s proliferation that will later fall. But, progesterone comes into play at a certain point, which inhibits the growth of this layer. In hyperestrogenism, estrogens roam freely without regulation of progesterone, causing bleeding more abundant and lasting.
  • Endocrinopathies: thyroid abnormalities and increased prolactin can lead to menorrhagia.
  • Coagulopathies: are blood disorders in which the components of the blood aggregation, such as platelets or clotting factors, are altered. This causes the blood to take longer to clot.

 

Functional causes

Functional causes are the most frequent, and only between 10 to 20% are organic causes, such as those described above. However, they must be ruled out yes or yes because they have a specific treatment.

Excessive and lasting functional bleeding is usually due to malfunction of the hypothalamic- pituitary-ovary axis. This axis regulates estrogen and progestogens so that they can be at adequate levels, depending on the menstrual cycle stage.

Many times, this malfunction is due to the immaturity of the system. For this reason, it usually occurs in young people, specifically adolescent girls. It leaves no mark on the medical tests that are carried out, and the only thing that can be done is to try to control the hormonal levels through medication.

Hormones regulate the menstrual period, so any alteration in them affects the days of bleeding.

When should I worry?

First, it must be ruled out whether the longest cycle is part of a woman’s normality or not. As we mentioned at the beginning, the duration and amount of the period are individual characteristics.

If the bleeding has lasted for more than 8 days for years, and there have been no signs or symptoms of illness, it may be completely normal and healthy. We don’t always have to be within the population mean.

On the other hand, if in each cycle the duration of menstruation has been less than 8 days and suddenly it lengthens, you have to be vigilant. It can mean that there is a hormonal alteration or some pathology that is in the reproductive system. This is the time to make a medical consultation.
