Irregular periods can be more than just an inconvenience—they might signal an underlying health concern. Understanding your cycle empowers you to take charge of your health. While a perfect 28-day cycle is ideal, it's normal for things to vary a bit.

A regular period shows up around the same number of days each cycle, usually within a range of 21 to 35 days. The length of your period (the bleeding days) also stays consistent. An irregular period throws those patterns out the window. Your period comes much earlier or later than usual (outside the 21-to-35-day range), or you miss a period entirely. The length of your bleeding also changes greatly every month. So, if you're concerned about irregular periods, it’s important to understand why they might be happening.

Irregular periods can be caused by various factors, from medical conditions to lifestyle factors. Here are a few of the most common causes:

Hormones play a major role in regulating your menstrual cycle, so imbalances can cause irregular periods. The two main hormones involved are estrogen and progesterone. When their levels are off, it can disrupt ovulation (the release of an egg) and make your period unpredictable. Some specific hormonal reasons for irregular periods are:

• Polycystic Ovary Syndrome (PCOS): This condition affects how your ovaries work and can lead to high levels of androgens (male sex hormones). This disrupts ovulation and can cause missed periods or irregular bleeding.
• Thyroid problems: An overactive or underactive thyroid can throw off your hormone balance, leading to irregular periods. Hypothyroidism, characterized by an underactive thyroid gland, often manifests as heavy or prolonged periods, while hyperthyroidism, marked by an overactive thyroid gland, may result in shorter, lighter periods or even amenorrhea (absence of menstruation).
• Birth control: Starting, stopping, or switching birth control pills can cause temporary hormonal fluctuations and irregular periods while your body adjusts.
• Perimenopause: As you approach menopause (typically in your 40s), your estrogen levels naturally start to decline. This can cause irregular periods for several years before they stop completely (menopause).

Stress can interfere with your menstrual cycle by disrupting hormone production. When you're stressed, your body produces higher levels of cortisol, a.k.a. the stress hormone. Elevated cortisol levels can disrupt the delicate balance of estrogen and progesterone needed for a regular cycle. This can lead to missed periods, heavier bleeding, or shorter cycles.

Stress can also affect the hypothalamus, a region of the brain that plays a crucial role in regulating hormone secretion. It disrupts communication between the brain and reproductive organs, contributing to irregular cycles. So, take control of stress to improve your overall well-being, including your menstrual cycle.

Did you know that fat tissue helps produce estrogen? Big weight changes (up or down) can disrupt hormone balance and cause irregular bleeding. If you're very underweight, your body might not make enough estrogen to ovulate, leading to missed periods. On the other hand, being overweight can result in excess estrogen, increasing your risk of PCOS.

Weight fluctuations also affect your body's sensitivity to insulin (a hormone that helps regulate blood sugar). This can also influence the hormones needed for regular periods.

Beyond hormonal imbalances, several health conditions can also cause irregular periods.

• Endometriosis is when tissue similar to your uterine lining grows outside your uterus, causing pain and heavy bleeding.
• Uterine fibroids, benign tumors in the uterus, may lead to similar issues.
• Pelvic inflammatory disease (PID), an infection in the reproductive organs, can also disrupt your cycle and cause irregular periods along with pain and unusual discharge.

If you suspect you might have an underlying health condition, see a doctor to get a proper diagnosis and treatment plan.

Smoking, excessive alcohol consumption, and poor sleep patterns also affect that time of the month. These lifestyle factors can impact hormone levels, such as estrogen, cortisol, and melatonin, which help regulate your monthly cycle.

Certain medications like chemotherapy drugs or birth control pills (when you first start or switch types) also disrupt hormones and cause irregular menses. Dilation and curettage (D&C) or uterine fibroid removal surgery can also temporarily affect your period.

The good news is there are steps you can take to help manage and get your cycle back on track. Explore some of the tips below:

To support hormonal balance, incorporate a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.

Engage in regular physical activity to promote circulation and overall well-being. If you’re not a fan of going to the gym or jogging, low-impact exercises like yoga can be a good place to start.

Practice stress-relief techniques such as deep breathing exercises or journaling to alleviate tension and promote hormonal harmony.

Consult with healthcare professionals for personalized advice and support on managing irregular periods, especially if you think you might have PCOS.

There are different ways to manage irregular periods, from making lifestyle changes to using hormone treatments. It's important to understand what's happening with your cycle and talk to a doctor.
