PCOS or Something Else? Understanding the Root Cause of Your Irregular Cycle

 Do you constantly find yourself wondering why your periods are late or irregular? You're not alone. One of the most common reasons women seek help from a gynaecologist is due to unpredictable menstrual cycles. While Polycystic Ovary Syndrome (PCOS) is often the first condition suspected, it’s not the only one that could be to blame. At Sarvesh Health City, the best gynaecologist in Hisar can help you uncover the real reason behind your cycle issues.

In this article, we’ll break down the difference between PCOS and other possible causes of irregular periods, how to recognize the symptoms, and what steps to take next.

What Is a “Normal” Menstrual Cycle?

Before diving into the reasons behind irregular cycles, let’s understand what a normal cycle looks like. A typical menstrual cycle ranges from 21 to 35 days, with bleeding lasting 2 to 7 days. While minor fluctuations are natural, consistently irregular periods could signal an underlying health issue.

What Counts as an Irregular Cycle?

You may have an irregular cycle if you experience:

  • Missed periods (amenorrhea)

  • Very frequent periods (more than once a month)

  • Infrequent periods (every few months)

  • Unpredictable bleeding or spotting between cycles

  • Extremely heavy or light flow

If any of these symptoms persist for more than three months, it’s time to consult a professional—preferably the best gynaecologist in Hisar at Sarvesh Health City.

PCOS: The Most Common Culprit

Polycystic Ovary Syndrome (PCOS) affects nearly 1 in 10 women of reproductive age. It is one of the leading causes of irregular periods.

Key Symptoms of PCOS:

  • Irregular or missed periods

  • Excess facial or body hair (hirsutism)

  • Acne and oily skin

  • Weight gain, especially around the abdomen

  • Multiple small cysts on the ovaries (visible via ultrasound)

  • Difficulty getting pregnant

What Causes PCOS?

PCOS is primarily a hormonal imbalance where the ovaries produce excessive androgens (male hormones). This disrupts normal ovulation, leading to delayed or missed periods.

But Is It Always PCOS?

Here’s the truth: Not all irregular periods are caused by PCOS. In fact, other medical and lifestyle factors can cause similar symptoms. Misdiagnosis or self-diagnosis can lead to frustration and delayed treatment. That's why visiting a qualified expert like the best gynaecologist in Hisar at Sarvesh Health City is essential.

Let’s explore some other possible causes.

Thyroid Disorders

Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can interfere with your menstrual cycle.

Symptoms That May Overlap with PCOS:

  • Fatigue

  • Weight gain or loss

  • Mood swings

  • Hair thinning

  • Irregular or absent periods

A simple thyroid function test (T3, T4, TSH) can help determine if your thyroid is the real issue.

High Stress Levels

In today’s fast-paced world, chronic stress is a silent disruptor of women’s health.

How Stress Affects Your Cycle:

  • Elevates cortisol, which interferes with ovulation

  • Suppresses hormone production needed for a regular cycle

  • May cause missed or delayed periods

If you’ve recently experienced emotional trauma, work-related stress, or major life changes, your cycle may be reflecting it.

Excessive Exercise or Eating Disorders

If you are an athlete or follow an intense workout regime, or if you're struggling with eating disorders like anorexia or bulimia, your body may reduce estrogen levels to preserve energy—causing missed or irregular periods.

Warning Signs:

  • Low body weight

  • Muscle fatigue

  • Missed periods for 3+ months (hypothalamic amenorrhea)

This is your body's way of signaling that it’s under too much physical strain.

Perimenopause and Menopause

Women in their late 30s to 40s may experience irregular cycles due to perimenopause—the natural transition to menopause.

Common Signs:

  • Hot flashes

  • Mood swings

  • Sleep disturbances

  • Unpredictable periods

It’s not PCOS; it’s just a shift in your reproductive phase. A gynaecologist at Sarvesh Health City can help distinguish between the two.

Uterine or Ovarian Conditions

Sometimes, irregular cycles are caused by physical abnormalities such as:

  • Fibroids (non-cancerous growths in the uterus)

  • Endometriosis

  • Ovarian cysts not related to PCOS

  • Pelvic inflammatory disease (PID)

These conditions often present with:

  • Severe pelvic pain

  • Heavy or prolonged bleeding

  • Painful intercourse

An ultrasound or pelvic exam by a gynaecologist can help pinpoint the exact cause.

Medications and Birth Control

Certain medications—especially hormonal birth control—can temporarily alter your cycle.

Examples:

  • Starting or stopping oral contraceptives

  • IUDs (especially copper-based ones)

  • Antidepressants

  • Anti-anxiety medication

Changes in cycle pattern are common in the first 3-6 months after a change in medication.

Diabetes and Insulin Resistance

Insulin resistance—often associated with Type 2 Diabetes—can disrupt ovulation in a way similar to PCOS.

Symptoms to Watch For:

  • Weight gain

  • Fatigue

  • Irregular menstruation

  • Dark patches of skin (acanthosis nigricans)

This can coexist with or mimic PCOS, so it’s important to get tested for blood sugar and insulin levels.

When to See a Gynaecologist?

If your cycle has become unpredictable and is affecting your daily life, it’s time to see a gynaecologist—especially one with deep expertise in diagnosing hormonal and reproductive issues. The best gynaecologist in Hisar at Sarvesh Health City offers a complete workup that may include:

  • Hormonal blood tests (FSH, LH, Prolactin, Testosterone)

  • Thyroid panel

  • Pelvic ultrasound

  • Lifestyle and dietary assessment

Early diagnosis leads to more effective treatment, whether it's PCOS or something else.

Irregular periods are your body’s way of signaling that something isn’t quite right. While PCOS is common, it’s not the only explanation. Thyroid issues, stress, lifestyle changes, or even uterine conditions can all be at play.
