MISSED PERIOD

35

A missed period Medically known as “Amenorrhea” can cause concern for many, especially if it occurs unexpectedly. Amenorrhea is a condition where a woman doesn’t get her periods even after reaching puberty, provided she isn’t pregnant and hasn’t entered menopause. This condition differs from having irregular periods because, in amenorrhea, periods are completely absent.

Although amenorrhea itself isn’t a disease, it can indicate an underlying medical issue that might require treatment. Hence, it’s essential to consult a doctor if you experience this condition.

Causes of Missed Periods

A missed period can result from a variety of factors, which differ between primary and secondary types.

Causes of Primary Amenorrhea

Primary amenorrhea, when a girl doesn’t get her first period by age 15, can be due to:

• Ovarian failure: The ovaries do not function properly.
• Central nervous system or pituitary gland issues: Problems with the brain or spinal cord, or with the pituitary gland, which produces hormones necessary for menstruation.
• Reproductive organ problems: Structural issues with the reproductive organs.

In many instances, doctors might not identify a specific reason for the absence of the first period.

Causes of Secondary Amenorrhea

Secondary amenorrhea occurs when a woman who previously had regular periods stops getting them. Common reasons include:

• Pregnancy
• Breastfeeding
• Discontinuation of birth control
• Menopause
• Certain birth control methods: Such as Depo-Provera injections or some intrauterine devices (IUDs).

Other factors that can lead to secondary amenorrhea include:

• Stress
• Poor nutrition
• Depression
• Certain medications: Including antidepressants, antipsychotics, blood pressure medications, and allergy drugs.
• Extreme weight loss
• Over-exercising
• Chronic illness
• Sudden weight gain or obesity
• Polycystic ovarian syndrome (PCOS)
• Thyroid disorders
• Tumors: Rarely, tumors on the ovaries or brain.
• Cancer treatments: Chemotherapy and radiation.
• Uterine scarring

Additionally, if you have had your uterus or ovaries removed, you will no longer menstruate.

Types of Amenorrhea(missed period)

Amenorrhea is classified into two main types:

1. Primary Amenorrhea:
   • This occurs when a young woman has not experienced her first period by the age of 15.
2. Secondary Amenorrhea:
   • This type is when a woman who previously had regular menstrual cycles stops getting her period for three or more months.

Prevalence

Amenorrhea is relatively common, particularly among women of reproductive age. While occasional missed periods are not uncommon, persistent irregularities should be evaluated by a healthcare professional.

Symptoms

The primary symptom is the absence of menstruation. Amenorrhea can come with several other symptoms, which vary depending on its cause:

• Pelvic pain
• Changes in vision
• Headaches
• Acne
• Hair loss
• Increased facial hair
• Milky discharge from nipples
• Lack of breast development (for primary amenorrhea)

Risk Factors

Several factors increase the risk of experiencing missed periods:

• Family History: Genetic predisposition to conditions like PCOS.
• Age: Adolescents and perimenopausal women are more likely to experience irregular cycles.
• Lifestyle: High stress, extreme weight changes, and excessive exercise.
• Health Conditions: Chronic illnesses and hormonal disorders.
• Medications: Use of specific drugs affecting hormonal balance.

Diagnosis

Diagnosing amenorrhea can be complex because it has many potential causes. Here’s how your doctor might approach it:

1. Medical History and Physical Exam:
   • The doctor will review your medical history and perform a physical and pelvic exam.
   • If you’re sexually active, a pregnancy test will likely be the first step to rule out pregnancy.
2. Diagnostic Tests:
   • Blood Tests: These check hormone levels, including follicle-stimulating hormone (FSH), thyroid-stimulating hormone, prolactin, and androgens (male hormones). Hormone imbalances can disrupt your menstrual cycle.
   • Imaging Tests: Ultrasounds, CT scans, and MRIs can reveal abnormalities in reproductive organs or locate tumors.
   • Hormone Challenge Test: You’ll take a hormone medication that should induce menstrual bleeding once stopped. If bleeding doesn’t occur, it might indicate a lack of estrogen.
   • Hysteroscopy: A small lighted camera is inserted through the vagina and cervix to examine the inside of your uterus.
   • Genetic Screening: This identifies genetic changes that might impair ovarian function, such as Turner’s syndrome.
   • Chromosome Tests (Karyotype): These detect missing, extra, or rearranged chromosomes that can cause amenorrhea.

Treatments for missed period

Treatment focuses on addressing the underlying cause of amenorrhea (Missed period). Here are some common approaches:

1. Hormonal Treatments:
   • Hormone replacement therapy or birth control pills can help restart your menstrual cycle.
2. Medication:
   • If a thyroid or pituitary disorder is identified, medications can manage these conditions.
3. Surgery:
   • Physical abnormalities in reproductive organs may require surgical intervention.
4. Lifestyle and Home Care:
   • If factors like stress, weight changes, or depression are affecting your cycle, managing these can be crucial. Seek support from friends, family, or your doctor.
   • Actively track your menstrual cycle and symptoms, noting any changes in diet, exercise, medications, and stress levels. Share this information with your doctor to aid in diagnosis and treatment.

Home Care Tips

• Maintain a Healthy Weight: Balanced diet and regular exercise.
• Manage Stress: Practices like yoga, meditation, and adequate sleep.
• Track Menstrual Cycle: Keeping a menstrual diary to monitor changes and patterns.
• Avoid Excessive Exercise: Balance physical activity with rest.

Prevention

Preventing missed periods involves maintaining overall health:

• Balanced Diet: Adequate nutrition supports hormonal balance.
• Regular Exercise: Moderate activity helps maintain a healthy weight.
• Stress Management: Techniques to reduce stress levels.
• Regular Check-ups: Routine medical examinations to monitor and manage health conditions.

When to See a Doctor

Consult a healthcare provider if:

• Periods are consistently missed for three or more cycles.
• You experience severe pain, unusual discharge, or symptoms of other health issues.
• There is a suspicion of pregnancy.
• You have symptoms of hormonal imbalances, like hair loss, acne, or weight changes.

Outlook/Prognosis

The prognosis for missed periods varies depending on the cause. Many women regain regular cycles with appropriate treatment and lifestyle changes. However, underlying conditions like PCOS or thyroid disorders may require long-term management. Early diagnosis and intervention are key to a favorable outcome..
