Irregular Periods: Causes, Symptoms, Diagnosis, and Treatment

What Are Irregular Periods?

Irregular periods are defined as periods that do not happen regularly and can occur irregularly, too often, too rarely, or with irregular bleeding. Irregular periods are different from amenorrhea, which implies a lack of periods.

Generally, the average menstrual period lasts 21 to 35 days and ranges from 2 to 8 days. Normally, most women experience menstrual periods for 4 to 7 days. If the period occurs or lasts outside this range, then it can be regarded as irregular.

Irregular periods are experienced by adolescents, premenopausal individuals, and people experiencing stress or hormonal imbalance, or specific health problems. Women who experience irregular periods will experience changes in the timing, duration, or amount of blood during their periods.

Some common menstrual disorders are:

• Amenorrhoea: It refers to the absence of menstrual periods lasting up to 90 days.

• Oligomenorrhea: Few menses during a year, typically less than 6 to 8.

• Dysmenorrhoea: It is painful menstruation.

Irregularities within the menstrual period should not always mean that something is wrong.

What Causes Irregular Periods?

Many conditions and lifestyle factors can affect the menstrual cycle.

• Hormonal Imbalance: Irregular periods may be due to a hormonal imbalance.

• Polycystic Ovary Syndrome (PCOS): Polycystic ovarian syndrome is a hormonal disease and has the following symptoms.

  • Irregular or absent menstruation.

  • Acne.

  • Weight gain.

  • Hair growth on the face.

  • Trouble conceiving.

• Thyroid Disorders: Hypothyroidism and hyperthyroidism are conditions in which the production of thyroid hormones can influence ovulation and menstruation.

• Stress and Other Factors: Stress, sudden weight loss, obesity, too much exercise, anorexia, and insomnia can lead to hormonal imbalance.

• Pregnancy: Pregnancy is one of the most common causes of missed periods. Sexually active individuals with delayed periods should consider taking a pregnancy test.

• Endometriosis: Endometriosis happens when cells resembling the lining of the uterus grow elsewhere and can result in the following conditions.

  • Menstrual cramps.

  • Bleeding.

  • Sexual pain.

  • Infertility.

• Pelvic Inflammatory Disease: This refers to an infection of the reproductive system that can cause abnormal bleeding and pelvic pain.

• Primary Ovarian Insufficiency: The condition occurs when the ovaries stop functioning before age 40.

• Uterine Fibroids and Polyps: These growths may cause the following.

  • Heavy periods.

  • Prolonged bleeding.

  • Pelvic pressure.

• Asherman Syndrome: Scarring inside the womb may cause light or infrequent menstruation.

• Pituitary Conditions: Abnormalities of the pituitary gland may disrupt hormone secretion.

• Some Drugs and Contraceptives: Hormonal contraception may result in irregular menstrual flow in the initial months. These are some examples:

  • Oral contraceptives.

  • Hormonal intrauterine devices.

  • Non-hormonal IUDs.

Irregular Periods in Teenagers

Menstrual irregularities occur quite often among teenagers. The first menstrual bleeding is known as menarche and takes place between the ages of 10 and 15 years. In the first two years following menarche, menstruation may be irregular as the hormonal system is developing and adjusting to changes in the body. Other causes that can influence the menstrual cycle include stress, sports, dieting, and fluctuations in weight. When periods do not come, pregnancy needs to be ruled out in sexually active teens.

Symptoms Associated With Irregular Periods

Irregular periods may occur with:

• Missed periods.

• Heavy bleeding.

• Spotting between periods.

• Severe cramps.

• Pelvic pain.

• Acne.

• Weight changes.

When to See a Doctor?

Medical evaluation is important if:

• Bleeding continues for more than seven days.

• Three or more menstrual periods are missed in one year.

• Heavy bleeding occurs.

• Pelvic pain is very severe.

• Bleeding continues after menopause.

• Weakness, fainting, or dizziness occurs.

Seek immediate medical attention if you have severe abdominal pain, fainting, or heavy bleeding during pregnancy, since an ectopic pregnancy may be possible.

How Are Irregular Periods Diagnosed?

For a proper diagnosis, doctors may perform a few tests:

• History and Physical Examination: The history considers cycle patterns, associated symptoms, medications, stress levels, and lifestyle factors.

• Pelvic Examination: A pelvic exam may reveal structural abnormalities.

  • Pregnancy.

  • Thyroid function.

• Surgical Procedures: In some cases, surgery may be required.

• Endometrial Ablation: This procedure destroys the uterine lining to reduce heavy bleeding.

• Myomectomy: Removes uterine fibroids.

• Uterine Artery Embolization: Shrinks fibroids by blocking their blood supply.

• Hysterectomy: This procedure involves the removal of the uterus in severe cases.

Early detection allows identifying the reasons that cause irregularities, including the development of PCOS, endometriosis, hypothyroidism, and uterine problems. Today's treatment methods include not only drugs but also lifestyle changes and minimally invasive surgery.
