Irregular periods can be a source of concern for many women. While a regular menstrual cycle lasts between 21 and 35 days, an irregular period can be defined as any cycle that deviates significantly from this range. This can include cycles that are shorter or longer than usual or periods that are heavier or lighter than normal. While the occasional irregular cycle is common and not typically a cause for concern, persistent irregular periods can be a sign of some underlying medical conditions. Here, a gynecologist in mukundapur, Kolkata will discuss some of the most common conditions that can cause irregular periods.

What are some conditions that cause irregular periods?

Polycystic Ovary Syndrome (PCOS):

It is a hormonal disorder that affects between 5 and 10% of women of reproductive age. It is characterized by the growth of small cysts on the ovaries, which can affect the regular production of hormones such as estrogen and progesterone. This hormonal imbalance can lead to irregular periods, as well as other symptoms such as acne, weight gain, and excess hair growth. Women with PCOS may also experience difficulty getting pregnant, as irregular ovulation can make it challenging to predict when ovulation will occur.

Thyroid Disorders:

The thyroid gland, which is located in the neck, produces hormones that regulate many bodily functions, including metabolism and the menstrual cycle. An overactive thyroid gland (hyperthyroidism) can cause periods to become shorter and lighter, while an underactive thyroid gland (hypothyroidism) can lead to longer and heavier periods. Other symptoms of thyroid disorders might include fatigue, weight changes, and changes in body temperature.


According to a top gynecologist in mukundapur, South Kolkata, stress can have a significant impact on the menstrual cycle. The body’s stress response triggers the release of hormones like cortisol, which can disrupt the regular production of estrogen and progesterone. This can cause irregular periods, as well as other symptoms such as mood swings and fatigue. In extreme cases, chronic stress can even cause periods to stop altogether.

Uterine Fibroids:

These are non-cancerous growths that occur in a woman’s uterus. While many women with fibroids experience no symptoms, some can experience heavy or prolonged periods, as well as pelvic pain or pressure. In some cases, fibroids may also lead to infertility.


It is a condition in which usually the tissue lining the uterus grows outside, causing pain and inflammation. Women with endometriosis may experience irregular periods, as well as pelvic pain, painful intercourse, and infertility. There are some treatments available to manage these symptoms and improve one’s quality of life.
We have discussed above some of the conditions that cause irregular periods. If you suffer from irregular periods, consult the best gynecologist doctor in mukundapur to find out the exact cause and get proper treatment.
