8 types of abnormal menstruation: What you should know

Every woman is unique, and menstruation, although we are used to a standard pattern, also varies. But the truth is that when there is an underlying problem, the menstrual cycle is altered, and up to 8 different types of abnormal menstruation can be detected. If you want to know what they are, here we explain them in depth.

What is considered an abnormal period?

Before diving into the types, it’s important to understand what qualifies as an abnormal period. A typical menstrual cycle lasts between 21 to 35 days, with bleeding lasting 2 to 7 days. However, it is considered an irregular menstrual cycle when you have heavier or lighter bleeding than usual or extreme pain, and missed cycles. All these signs could mean an abnormal menstruation.

How do irregular cycles affect fertility?

Irregular periods can make it more difficult to predict ovulation, which plays a crucial role in conception. Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, or chronic stress can disrupt hormonal balance and lead to inconsistent ovulation or no ovulation at all.

This unpredictability reduces the chances of timing intercourse correctly, thereby affecting women’s fertility. If you are trying to conceive and experiencing menstrual irregularities, it’s a good idea to consult a fertility specialist.

These are the 8 types of abnormal menstruation you should know

There isn’t just one way a menstrual cycle can be irregular. From missed periods to unusually heavy flows, each variation has its own name, characteristics, and potential causes. Understanding these types can help you identify symptoms early and decide when to seek medical help.

1. Amenorrhea: Missing your period

Amenorrhea refers to the absence of menstruation. It’s divided into two types:

• Primary amenorrhea: when periods haven’t started by age 15.
• Secondary amenorrhea: when someone who previously had regular periods stops menstruating for three months or more.

Common causes include hormonal imbalances, extreme weight loss, stress, or underlying medical conditions like PCOS or thyroid disorders.

2. Oligomenorrhea: Infrequent periods

People with oligomenorrhea have cycles longer than 35 days or fewer than nine periods per year. Although it is believed that you can induce your period by suffering from oligomenorrhoea, the truth is that it’s often linked to hormonal disorders, stress, excessive exercise, or chronic illnesses.

3. Menorrhagia: Heavy menstrual bleeding

This is characterized by abnormally heavy or prolonged periods. You may need to change sanitary products every hour, or your period may last more than 7 days. This type of abnormal menstruation is often caused by hormonal imbalances, fibroids, or bleeding disorders.

4. Hypomenorrhea: Light menstrual flow

Hypomenorrhea refers to unusually light menstrual bleeding. Some individuals may only experience spotting, while others may have extremely short periods. It can result from hormonal birth control, stress, or structural abnormalities of the uterus.

5. Polymenorrhea: Frequent periods

If your menstrual cycle is shorter than 21 days and you bleed more often than usual, you may have polymenorrhea. This condition can stem from thyroid dysfunction, perimenopause, or certain medications.

6. Dysmenorrhea: Painful periods

While some discomfort is common, dysmenorrhea refers to severe, cramping menstrual pain that interferes with daily activities. Primary dysmenorrhea is due to natural hormone activity, while secondary dysmenorrhea may be linked to endometriosis or pelvic inflammatory disease.

7. Metrorrhagia: Bleeding between periods

Metrorrhagia is irregular bleeding that occurs outside of your normal cycle. It may be spotting or more significant bleeding. Causes can include hormonal fluctuations, uterine fibroids, or even early signs of pregnancy complications.

8. Premenstrual Syndrome (PMS) and PMDD

Though not strictly types of irregular periods, PMS and PMDD (Premenstrual Dysphoric Disorder) are closely tied to menstruation. PMS involves emotional and physical symptoms before your period, while PMDD is a more severe form that can interfere with daily life and mental health.

When to see a doctor for menstrual irregularities?

If your menstrual irregularities are frequent, severe, or affect your quality of life, it’s time to consult a gynecologist. Irregular periods can be a sign of hormonal imbalances, reproductive issues, or other medical conditions that require treatment.

Keeping a period diary or using a period tracking app can help you monitor symptoms and provide valuable information to your doctor.
