What Your Irregular Periods Could Be Telling You About Your Hormones

Your menstrual cycle is more than just a monthly inconvenience; it's a vital sign of your overall hormonal health. When you experience irregular periods, your body is often sending you an important message about your endocrine system. 

At Longoria OBGYN in El Paso, Texas, Leonardo A. Longoria K., MD, helps women decode these signals. Through our comprehensive women's health services, we work to find the root cause of your cycle changes so you can live comfortably and confidently.

How does PCOS trigger irregular periods?

Polycystic ovary syndrome (PCOS) is one of the most common reasons for irregular periods, causing your body to skip ovulation due to elevated androgen and insulin levels. When you don't ovulate regularly, your uterine lining is exposed to continuous estrogen without the balancing effect of progesterone. 

This chronic hormonal imbalance can lead to abnormal tissue growth over time. Research published in the Medical Journal of the Islamic Republic of Iran shows that women with PCOS face an increased risk of developing endometrial cancer compared to those with regular cycles, making early diagnosis and lifestyle management essential to restore your hormonal balance.

Can thyroid issues cause irregular periods?

An underactive or overactive thyroid gland directly disrupts the hormones responsible for your monthly cycle. Your thyroid and reproductive systems are deeply connected, meaning a dip in thyroid hormones can halt ovulation and cause heavy, prolonged, or missed periods.

According to a study in Cureus, thyroid dysfunction — specifically hypothyroidism — is present in approximately 24% of reproductive-aged women who experience abnormal uterine bleeding. 

To get a clear picture of your reproductive health, Dr. Longoria often uses diagnostic tools like a pelvic ultrasound alongside hormone panels to pinpoint the exact cause of your symptoms.

Is a normal menstrual cycle always 28 days?

A healthy menstrual cycle doesn't have to rigidly last exactly 28 days. While many people believe any deviation from this timeline is a sign of trouble, medical consensus defines a normal adult cycle as anywhere from 21-35 days. 

Minor month-to-month variations are completely normal and show that your body is responding to everyday life. However, if your cycle consistently falls outside this window, or if you experience fewer than eight periods a year, it's time to seek professional care.

You don't have to guess what your body is trying to tell you. Whether you're dealing with PCOS, thyroid changes, or other hormonal shifts, we're here to provide the personalized care you deserve.
