Understanding Abnormal Periods: 8 Types You Should Know About


 8 Abnormal Menstruation Types

 

1. Amenorrhea


Amenorrhea refers to the absence of menstruation for three or more consecutive cycles in someone who has previously menstruated and is not pregnant or breastfeeding. This can be classified as:


Primary Amenorrhea: If you haven't had a period by age 15 (or by age 13 with no signs of breast development).


Secondary Amenorrhea: If your periods stop for three or more cycles after previously having regular periods.


Causes of amenorrhea can vary depending on the type:


Primary Amenorrhea: Chromosomal abnormalities, underdeveloped reproductive organs, or hormonal imbalances.


Secondary Amenorrhea: Stress, sudden weight loss, excessive exercise, hormonal imbalances due to PCOS (polycystic ovary syndrome) or thyroid disorders, certain medications, and uterine scar tissue from surgery.


 

2. Oligomenorrhea


Oligomenorrhea describes infrequent periods with a cycle length exceeding 35 days or fewer than eight cycles in a year. This can be caused by:


  • Similar to amenorrhea, PCOS, thyroid issues, or birth control pills can contribute.

  • Both extreme thinness and obesity can disrupt ovulation, leading to infrequent periods.

  • Chronic stress can wreak havoc on your hormones, affecting your cycle length.

  • Celiac disease, pelvic inflammatory disease (PID), and certain medications can also contribute.


 

3. Dysmenorrhea


Dysmenorrhea refers to painful menstrual cramps that can significantly impact your daily life. It can be categorized as:


  • Primary Dysmenorrhea: Painful periods without an underlying pelvic condition, affecting up to 50% of menstruating individuals.

  • Secondary Dysmenorrhea: Pain caused by an underlying medical condition like endometriosis, uterine fibroids, or adenomyosis.


Symptoms of dysmenorrhea can include:


  • Severe cramping in the lower abdomen

  • Lower back pain

  • Thigh pain

  • Nausea and vomiting

  • Diarrhea

  • Headache

  • Fatigue


 

4. Menorrhagia


Menorrhagia refers to excessively heavy menstrual bleeding, lasting longer than seven days or requiring frequent pad/tampon changes (every 1-2 hours).  This can be caused by:


Hormonal imbalances: Similar to other menstrual issues, hormonal imbalances can disrupt the regulation of the uterine lining, leading to heavy bleeding.

Uterine fibroids: Benign tumors in the uterus can cause heavy and prolonged periods.

Adenomyosis: When endometrial tissue grows within the muscular wall of the uterus, it can lead to heavy and painful periods.

Endometriosis: Tissue similar to the uterine lining grows outside the uterus, potentially causing heavy bleeding.

Pelvic inflammatory disease (PID): Inflammation of the reproductive organs can lead to irregular and heavy bleeding.


 

5. Metrorrhagia


Metrorrhagia refers to bleeding between regular menstrual periods. This unexpected spotting or bleeding can be caused by:


  • Changes in hormone levels throughout your cycle, especially during ovulation or before menopause, can lead to spotting.

  • Starting, stopping, or switching birth control pills can cause irregular bleeding until your body adjusts.

  • These growths can cause spotting or bleeding between periods.

  • Pelvic inflammatory disease (PID): Inflammation can lead to irregular bleeding, including spotting.

  • While less common, abnormal cervical cells can cause bleeding after intercourse or between periods.


 

6. Polymenorrhea


Polymenorrhea describes having periods that occur more frequently than every 21 days. This can be caused by:


  • Similar to other menstrual issues, hormonal imbalances can disrupt the regulation of ovulation, leading to frequent periods.

  • Starting or stopping certain birth control methods can cause your cycle to become shorter.

  • These growths can cause irregular bleeding patterns, including frequent periods.

  • If ovulation doesn't happen regularly, the lining of the uterus may shed more frequently, leading to short cycles.


 

7. Hypomenorrhea


Hypomenorrhea refers to unusually light periods with minimal bleeding.  While some women naturally experience lighter periods throughout their lives, a significant decrease in flow compared to their usual pattern can be a cause for concern. Here are some potential reasons for hypomenorrhea:


  • Similar to other menstrual irregularities, hormonal imbalances can affect the thickening of the uterine lining, leading to lighter periods. Conditions like hypothyroidism or low estrogen levels can be contributing factors.

  • Chronic stress can disrupt your hormonal balance, impacting ovulation and potentially leading to lighter or skipped periods.

  • Certain hormonal birth control methods, such as birth control pills or intrauterine devices (IUDs), can thin the uterine lining, resulting in lighter periods.

  • Some medical conditions like Asherman's syndrome (scarring of the uterine lining) or eating disorders can contribute to hypomenorrhea.


 

8. Hypermenorrhea


Hypermenorrhea, the opposite of hypomenorrhea, describes excessively heavy menstrual bleeding. This can be characterized by:


  • Bleeding that soaks through pads or tampons every hour or two

  • Needing to change sanitary products frequently throughout the night

  • Periods lasting longer than seven days


Here's a glimpse into some potential causes of hypermenorrhea:


  • As with other menstrual irregularities, hormonal imbalances can play a role. Conditions like uterine fibroids or endometriosis can disrupt hormonal regulation, leading to heavy bleeding.

  • These are non-cancerous growths in the uterus that can cause heavy and prolonged periods, along with cramping and pelvic pain.

  • When endometrial tissue (the lining of the uterus) grows within the muscular wall of the uterus, it can lead to heavy and painful bleeding.

  • Tissue similar to the uterine lining grows outside the uterus, potentially leading to heavy and irregular bleeding.

  • Inflammation of the reproductive organs can cause heavy and irregular bleeding.


 

Taking Charge of Your Menstrual Health


Understanding your menstrual cycle is a crucial step towards maintaining good overall health. Here are some tips to empower yourself:


  • Use a period tracker app or a simple calendar to record the dates of your periods, their length, and any associated symptoms like cramps or bloating. This information can be invaluable for discussing and identifying patterns with your doctor.

  • Eating a balanced diet, exercising regularly, and getting enough sleep can all positively impact your menstrual cycle.

  • Chronic stress can wreak havoc on your hormones. Explore relaxation techniques like yoga, meditation, or deep breathing to help manage stress levels.

  • Don't be shy! Discuss any concerns you have about your menstrual cycle with your doctor. They are there to support your health and well-being.


When to Seek Professional Help


When to Seek Professional Help For Irregular Periods

While occasional variations in your menstrual cycle are normal, some situations warrant a visit to your healthcare provider. Here are some red flags to watch out for:


  • Heavy bleeding that soaks through pads or tampons every hour for several hours in a row

  • Periods lasting longer than seven days consistently

  • Extreme pain that interferes with daily activities

  • Bleeding between periods or after intercourse

  • Missed periods for three or more cycles if you're not pregnant or breastfeeding

  • Significant changes in your usual cycle pattern that persist

  • Unusual vaginal discharge with an unpleasant odor or color


If you experience any of these symptoms, don't hesitate to schedule an appointment with your doctor. They can perform a physical examination, review your medical history, and potentially order additional tests to determine the underlying cause.  Early diagnosis and intervention can help manage the condition and ensure optimal menstrual health.


Final Takeaway


Your menstrual cycle is a unique and essential part of your being. While occasional variations are normal, understanding the different types of abnormal menstruation empowers you to navigate any irregularities confidently. You can ensure optimal menstrual health by recognizing potential causes and seeking professional guidance when needed. Remember, a healthy and predictable period is a window into your overall well-being. Embrace the knowledge and open communication with your doctor, and celebrate your body's natural rhythm!
