Irregular periods can be a puzzling and even a little bit scary experience for most individuals. Although changes in your menstrual cycle are normal from time to time, regular or excessive irregularities may be indicative of something more serious. Now let’s have a closer look at what leads to irregular periods, typical symptoms, and how you can deal with them.
What Constitutes Irregular Periods?
Physicians usually characterize an irregular menstrual cycle as one that exceeds 38 days in duration or where the length of each cycle varies by more than 7–9 days. While it’s perfectly normal to see some variation in your period, persistent or marked changes in your rhythm may be worth exploring with a physician.
Common Causes of Irregular Periods
There are a variety of factors that can disrupt the natural flow of your menstrual cycle. These include:
Stress: Chronic stress can mess with the hormonal balance that regulates your period. During the COVID-19 pandemic, for example, many people reported longer and heavier periods due to increased stress levels.
Hormonal Imbalances: Disorders such as polycystic ovary syndrome (PCOS) and thyroid disease can impact your menstrual cycle. For example, PCOS can lead to skipped periods or heavy bleeding because of increased levels of androgens, whereas hypothyroidism can result in longer, heavier periods along with tiredness and weight gain.
Fibroids: These benign growths within the uterus may result in painful, heavy periods that could be heavy enough to cause anemia.
Endometriosis: Occurring in approximately 1 in 10 women of reproductive age, endometriosis occurs when tissue like the uterine lining develops outside the uterus. It may result in debilitating pain and abnormally heavy bleeding.
Weight Changes: Sudden or drastic weight loss may completely halt periods due to a condition called hypothalamic amenorrhea, which occurs owing to a deficiency of estrogen. Similarly, being underweight or overweight may disrupt hormonal balance and cause irregular periods.
Birth Control: Hormonal types of birth control, such as pills, patches, and IUDs, can change your pattern of bleeding. Some women get spotting or irregular bleeding, while others get their period to cease altogether.
Menopause and Perimenopause: These are natural phases of life accompanied by changes in hormones that cause irregular periods, spotting, or even skipped periods.
Spotting Instead of a Period
Spotting, or lighter than normal bleeding that may appear as pink, red, or brown discharge, can occur for several different reasons. Pregnancy, for instance, can produce spotting in the first trimester due to bleeding caused by implantation or irritation in the cervix. Spotting can be triggered by hormonal imbalance, fibroids, polyps in the uterus, and even stress.
When to Seek Medical Advice
While most irregular periods are not a cause for concern, some symptoms should make you consult a healthcare provider. These include:
- Bleeding after menopause.
- Spotting or bleeding during pregnancy.
- Periods longer than seven days or heavy enough to saturate a pad or tampon for an hour.
- Any changes in your cycle length or frequency that are unexplained?
Diagnosing and Addressing Irregular Periods
Physicians diagnose conditions such as PCOS, thyroid problems, or fibroids through a combination of blood work, ultrasounds, and your medical history. Treatment varies depending on the cause and your needs, like if you’re trying to become pregnant. For example, medications that stimulate ovulation can be prescribed for individuals with PCOS who are trying to become pregnant.
Making changes to your lifestyle can also help manage irregular periods. Reducing stress, maintaining a healthy weight, and cutting back on sugary foods can help bring your cycle back into balance. In some cases, hormonal birth control can help regulate your menstrual patterns.
Knowing why your periods are irregular is important to receive the proper treatment. Regardless of whether they are due to stress, hormonal shifts, or other reasons, seeing a healthcare provider for guidance and exploring various forms of treatment can restore your cycle—and bring a sense of peace of mind.
