Delayed periods or menstruation can be a cause of concern for many women. While pregnancy is one of the most common reasons for a missed period, there could be other underlying factors responsible for the delayed menstruation.

In this article, we will discuss the lesser-known causes of delayed periods.

1. Thyroid Imbalance

Thyroid hormones play a crucial role in the regulation of the menstrual cycle. An overactive or underactive thyroid gland can cause fluctuations in the levels of these hormones, which can lead to delayed periods.

Hypothyroidism (underactive thyroid) is more likely to cause missed or irregular periods than hyperthyroidism (overactive thyroid). A simple blood test can determine if the thyroid gland is functioning correctly.

2. Polycystic Ovary Syndrome (PCOS)

PCOS affects up to 10% of women of reproductive age. The condition is characterized by the presence of small cysts on the ovaries.

Women with PCOS may experience irregular or absent periods, along with other symptoms such as acne, weight gain, and excess hair growth. PCOS is caused by hormonal imbalances and can be diagnosed through blood tests and ultrasound scans.

3. Extreme Weight Loss or Gain

Drastic changes in weight, whether weight loss or weight gain, can cause hormonal imbalances and irregular periods. Low body fat levels can reduce the production of estrogen, causing delayed menstruation or even amenorrhea (absence of periods).

On the other hand, being overweight can lead to increased levels of insulin, which can also disrupt the menstrual cycle.

4. Stress

Stress can impact the menstrual cycle by altering the levels of hormones such as cortisol and adrenaline. Prolonged stress can lead to irregular periods, skipped periods, or even amenorrhea.

Incorporating stress-reducing techniques, such as meditation or yoga, can help regulate the menstrual cycle.

5. Medications

Certain medications such as birth control pills, antipsychotics, and chemotherapy drugs can cause delayed periods or irregular menstrual cycles.

If you are experiencing delayed periods after starting a new medication, it is best to speak to your healthcare provider to determine if the medication is the cause of the delayed menstruation.

6. Premature Ovarian Failure

Premature ovarian failure occurs when the ovaries stop producing eggs before the age of 40. This condition can lead to delayed periods or even complete cessation of menstruation.

In addition to missed periods, other symptoms of premature ovarian failure include hot flashes, vaginal dryness, and mood swings. Women with premature ovarian failure may need to undergo hormone replacement therapy to alleviate the symptoms.

7. The Perimenopausal Phase

The perimenopausal phase is the period leading up to menopause when the ovaries start to produce fewer eggs. During this phase, women may experience irregular periods that can be delayed or skipped altogether.

Other symptoms of perimenopause include hot flashes, night sweats, vaginal dryness, and mood changes.

8. Uterine Fibroids

Uterine fibroids are non-cancerous growths that develop in the uterus. While most fibroids do not cause any symptoms, larger fibroids can cause heavy or irregular periods, which can lead to delayed menstruation.

Other symptoms of fibroids include pelvic pain, frequent urination, and back pain.

9. Implantation Bleeding

Implantation bleeding is a sign of early pregnancy that occurs when the embryo implants itself in the uterine lining. The bleeding is usually light and occurs a few days before the expected period.

Implantation bleeding is often mistaken for a delayed period, and a pregnancy test may be necessary to confirm pregnancy.

10. Ovarian Cancer

Ovarian cancer is a rare but serious cause of delayed periods. Other symptoms of ovarian cancer include abdominal bloating, pelvic pain, and difficulty eating.

If you have been experiencing delayed periods and any of these symptoms, it is crucial to speak to a healthcare provider for evaluation and diagnosis.

Conclusion

Delayed periods can be caused by a variety of factors, including thyroid imbalance, PCOS, extreme weight loss or gain, stress, medications, premature ovarian failure, the perimenopausal phase, uterine fibroids, implantation bleeding and, in rare cases, ovarian cancer. If you are experiencing delayed periods, it is essential to speak to a healthcare provider to determine the underlying cause and receive the necessary treatment.
