8 Types of Abnormal Menstruation

Written by Boris Brut

Menstruation is a natural process, but it’s not always straightforward. Many people wonder if their menstrual cycle is within the norm – whether it’s the level of pain, the amount of bleeding, or changes in their period. There are 8 types of abnormal menstruation, and recognizing the signs can help you address concerns early. Understanding what’s normal, both medically and personally, is key to recognizing when something might be wrong. It can help you pinpoint potential causes related to lifestyle, hormones, or overall health. Continue reading to learn about the signs and symptoms of the 8 main types of abnormal menstruation and what steps you can take if you think you might be experiencing one of them.

How Long Is a Menstrual Cycle?

A period marks the beginning of the menstrual cycle, with bleeding typically lasting between three and seven days, averaging around five days. Once bleeding stops, the follicular phase continues. This is followed by ovulation, which lasts about one day, and the fertile window, lasting approximately five days. The final phase is the luteal phase, which typically lasts around two weeks but can range from 11 to 17 days. The average menstrual cycle is often cited as 28 days, but many individuals experience cycles that vary in length, ranging from 21 to 35 days. These cycles may not be consistent in how each phase changes in length, except for ovulation, which remains a single-moment event. For example, some may experience a longer period with a shorter luteal phase or other variations.

What Is Abnormal Menstruation?

Abnormal menstruation refers to changes in the menstrual cycle that significantly impact your daily life. This can include symptoms such as pain severe enough to interfere with daily tasks, missed periods, or spotting in between menstrual bleeding. There are various forms of abnormal periods, each potentially caused by different factors. Common causes include hormonal imbalances, stress, and underlying health conditions. Tracking your cycle with tools like the Mira Hormone Monitor and Mira Wands can provide valuable insights into how your hormones or lifestyle may be affecting your periods. This tracking is particularly effective when paired with an app like the Mira App, which helps you monitor and understand these fluctuations more easily.

The 8 Types of Abnormal Menstruation

There are eight common types of abnormal menstruation that healthcare providers typically diagnose. Let’s explore each one, including their causes and potential solutions for those experiencing these conditions.

Amenorrhea

Amenorrhea is the condition where a person either does not menstruate for an extended period or has not started their period by age 15. While occasional missed periods are common, amenorrhea refers to consistently missing multiple periods for three months in a row or more. Depending on the underlying cause, additional symptoms may include headaches, vision changes, new facial hair, pelvic pain, acne, hair loss, and nipple discharge. If you miss three consecutive periods, it’s important to consult a healthcare professional. Pregnancy is the most common cause of amenorrhea, so if you’ve had unprotected sex, it’s advisable to take a pregnancy test to confirm or rule it out. Other potential causes include chronic or excessive stress, hormonal disorders like Polycystic Ovary Syndrome (PCOS) or thyroid issues, and extreme weight loss.


Oligomenorrhea

This is when a person has infrequent or irregular menstruation. This is different from amenorrhea, as periods do happen, but the frequency and irregular cycles are the focal points of oligomenorrhea. Causes of oligomenorrhea include PCOS, thyroid issues, excessive exercise, and eating disorders. Sometimes, these causes can be addressed by balancing your hormones through your diet. If you aren’t certain which supplements are best, the Mira PCOS Supplements contain all the vitamins needed to help with this.

Polymenorrhea

Poly, meaning 'many,' may make this one clearer to some, but polymenorrhea refers to shorter cycles that cause periods to become more frequent – some people may have a period every two weeks. This condition can be caused by hormonal imbalances and uterine abnormalities like fibroids or polyps.

Menorrhagia

Menorrhagia is characterized by a menstrual period longer than normal or a heavy bleeding period. This may involve bleeding for more than seven days or experiencing bleeding so heavy that you soak through more than two pads or tampons in an hour. Such episodes can be uncomfortable and may lead to complications like anemia and fatigue, especially for those who have continuous menstrual bleeding for months. If the bleeding is excessive enough to cause these symptoms or if there is a noticeable number of clots in the menstrual blood, it's crucial to consult a healthcare provider to investigate the underlying cause.

Metrorrhagia

Bleeding between periods is known as metrorrhagia. This condition can be caused by uterine fibroids or polyps, pelvic inflammatory disease, or certain types of hormonal contraceptives. While bleeding between periods may not always seem alarming, it’s important to have it investigated promptly to identify and address the underlying cause.

These three terms – polymenorrhea, menorrhagia, and metrorrhagia – are outdated. Now, ‘abnormal uterine bleeding’ (AUB) is used instead. AUB is the preferred and more comprehensive term in clinical settings.

Dysmenorrhea

For many people who menstruate, cramps that cause discomfort and mild pain are within the bounds of normal. While uncomfortable, they should not be severe enough to interfere with daily activities. However, if the pain becomes excessive and debilitating, preventing you from doing the things you need or want to do, it could be a sign of dysmenorrhea. There are two types: primary and secondary.

Primary dysmenorrhea occurs without an underlying medical condition. While this can be frustrating, as there's no specific issue to address, it’s important to focus on symptom management. Hormonal contraception is often offered, and depending on the type, it may stop your cycle altogether. If not, treatment typically involves heat application, pain relievers, dietary adjustments, and incorporating gentle exercises into your routine.

Secondary dysmenorrhea is caused by an underlying condition, such as endometriosis, uterine fibroids, or pelvic inflammatory disease (PID). In these cases, addressing the underlying condition is often the key to alleviating the pain.

Hypomenorrhea

Hypomenorrhea refers to extremely light periods or less menstrual bleeding. While some may prefer lighter periods, those with hypomenorrhea might face fertility challenges. Reduced menstrual blood can indicate that the uterine lining doesn't thicken enough, potentially affecting uterine function. Common causes include hormonal contraceptives, stress, and underlying health conditions such as PCOS or eating disorders.

Postmenopausal Bleeding

Postmenopausal bleeding refers to bleeding that occurs after menopause. It can be caused by hormonal therapies, uterine cancer, or conditions such as cervical infections, inflammation, or thickening of the uterine lining. Treatment focuses on identifying and addressing the underlying cause, particularly if a serious condition is suspected.

Common Causes of Abnormal Menstruation

One of the most common causes of irregular periods and abnormal bleeding is hormonal imbalance. The menstrual cycle is fundamentally a hormonal process, so any disruption in these hormones can lead to unexpected changes in menstruation.

Lifestyle factors also play a significant role in menstrual health. Diet, physical activity, and weight all influence hormone levels. While stress is a well-known factor, nutrition is equally important – not just in terms of calorie intake but also in how certain foods promote hormone production. Vitamins B, D, and omega-3 fatty acids, for example, support the synthesis of estrogen and progesterone, making a balanced diet essential for hormonal stability. Weight is another key factor, as body fat helps regulate hormones. Both excessive and insufficient body fat can disrupt the menstrual cycle, though it’s important for individuals to feel comfortable in their bodies while maintaining overall health.

Additionally, medical conditions such as PCOS, endometriosis, adenomyosis, and thyroid disorders can impact menstruation due to their effects on hormone levels. Treating these conditions may help regulate the menstrual cycle, though some can only be managed rather than cured. Understanding this can help set realistic expectations – while there’s no instant fix, healthcare providers work to find the best possible treatment to improve menstrual health.

When to Seek Medical Advice

Early detection is key when it comes to the 8 types of abnormal menstruation. While some people may try to endure uncomfortable periods, if your symptoms interfere with daily life or impact fertility, seeking medical attention as soon as possible is essential. Many causes of abnormal menstruation are treatable or benign, but some may indicate more serious underlying conditions that require prompt evaluation.

Treatment Options for Abnormal Menstruation

Even before visiting a doctor, there are steps you can take to help manage irregular periods. Lifestyle adjustments – such as modifying your diet, exercise routine, and stress management – can significantly impact menstrual health. Diet isn’t just about calorie intake but also about optimizing overall well-being through essential vitamins and nutrients. Certain teas, like Mira Fertility Tea, may offer benefits due to their antioxidant properties, while the ritual of preparing and drinking tea can also promote relaxation.

If lifestyle changes are not enough, medical treatments may be necessary. These can include hormonal therapies or, in more severe cases, procedures such as endometrial ablation – a surgery that removes a thick layer of the uterine lining. If you're unsure which option is best for you, consulting a fertility specialist, such as those at the Mira Hormone Health Clinic for Fertility, can help you explore your treatment options and find the most suitable approach.

Conclusion

When something isn’t right with your menstrual cycle, it can serve as a warning sign – much like a check engine light – indicating that something needs attention before it worsens. While it may feel frustrating or even taboo to discuss menstrual health with a doctor, ignoring the issue can allow it to escalate.

You’re not alone – many people experience abnormal menstruation or irregular periods. Understanding what’s normal for your body, tracking symptoms, and addressing underlying conditions can improve overall health and well-being. By gaining insight into your cycle, you can shift from dreading your period each month to feeling informed and in control.

Frequently Asked Questions

Can stress cause abnormal menstruation?

Yes, stress can contribute to abnormal menstruation. When stress levels remain elevated for extended periods, the body produces higher amounts of hormones like cortisol and adrenaline, which can disrupt the menstrual cycle.

How can I track irregular periods effectively?

Tracking irregular periods is best done using hormonal monitoring tools and period-tracking apps. These tools can help identify patterns and provide valuable insights into your cycle.

Are natural remedies effective for abnormal menstruation?

Lifestyle factors such as stress management, a nutrient-rich diet, and regular exercise can help regulate menstruation if the underlying cause is lifestyle-related. However, if an underlying medical condition is responsible, these remedies may assist in symptom management but won’t replace the need for medical treatment.
