Missed Periods: Amenorrhea

Missed periods, also known as amenorrhea, can occur for various reasons. Occasional irregularities in your menstrual cycle are not uncommon. However, if you consistently experience missed periods or other concerning symptoms, it’s advisable to consult a healthcare provider. They can help determine the underlying cause and provide appropriate guidance and treatment if necessary.


Here are some common causes:

  1. Pregnancy: The most common cause of a missed period is pregnancy. If you’ve had unprotected sex and your period is late, consider taking a pregnancy test.
  2. Stress: Emotional and physical stress can disrupt your hormonal balance, leading to missed periods. This can include major life changes, work pressure, or personal stress.
  3. Extreme Weight Changes: Significant weight loss or gain can affect hormone production and cause missed periods. Eating disorders and excessive exercise can also contribute to this.
  4. Hormonal Imbalance: Hormonal disorders like polycystic ovary syndrome (PCOS) or thyroid issues can disrupt your menstrual cycle.
  5. Medications: Certain medications, like birth control, can affect your menstrual cycle. Some medications, such as antipsychotics or chemotherapy drugs, may also lead to missed periods.
  6. Menopause: If you’re in your late 40s or 50s, missed periods may be a sign of the onset of menopause, which is a natural part of aging.
  7. Overexercising: Intense physical activity, especially when combined with low body fat, can cause amenorrhea. This is often referred to as the “female athlete triad.”
  8. Contraception: Some birth control methods, like the hormonal IUD or contraceptive injections, can cause a decrease in menstrual bleeding or even stop periods altogether.
  9. Medical Conditions: Certain medical conditions, such as uterine fibroids, pelvic inflammatory disease, or endometriosis, can lead to irregular or missed periods.
  10. Breastfeeding: In the postpartum period, breastfeeding can suppress ovulation and cause missed periods.


When should you see a health professional for missed periods?

If you experience missed periods, there are certain situations and symptoms that should prompt you to seek advice from a healthcare professional. Here are some guidelines for when to consider scheduling an appointment:

  1. Pregnancy Concerns: If you’ve had sexual intercourse and there’s a chance you might be pregnant, a missed period is a significant indicator. It’s a good idea to take a pregnancy test first. If the test is negative, but you’re still concerned, consult a healthcare provider for further evaluation.
  2. Consistent Irregularities: If your periods are consistently irregular, with frequent missed periods or unpredictable cycles, it’s a good reason to see a healthcare professional. They can help identify underlying causes such as hormonal imbalances, polycystic ovary syndrome (PCOS), or other conditions.
  3. Sudden Changes: If you’ve previously had regular menstrual cycles and you suddenly experience missed periods without an obvious cause like pregnancy or menopause, consult a healthcare provider. This could be a sign of an underlying issue.
  4. Severe Symptoms: If you experience severe pain, heavy bleeding, or other concerning symptoms along with missed periods, it’s crucial to seek medical attention. Conditions like endometriosis or uterine fibroids could be contributing to both the symptoms and missed periods.
  5. Excessive Weight Changes: Rapid and significant weight loss or gain, as well as eating disorders, can lead to missed periods. If you suspect these factors are involved, consulting a healthcare provider is essential.
  6. Underlying Health Conditions: If you have known health conditions like PCOS, thyroid disorders, or other hormonal issues and you experience missed periods or significant changes in your menstrual cycle, your healthcare provider can help manage these conditions and their impact on your periods.
  7. Adolescence: For teenage girls, it’s common to have irregular periods during the first few years after menstruation begins. However, if you’re concerned about the extent of irregularity or other symptoms, consulting a healthcare provider can provide reassurance and guidance.
  8. Perimenopause or Menopause: If you’re in your late 40s or early 50s and experiencing changes in your menstrual cycle, it might be a sign of perimenopause or menopause. While this is a natural part of aging, discussing your symptoms with a healthcare provider can help manage the transition and address any related health concerns.

In all cases, it’s important to consult a healthcare professional if you have any doubts or concerns about your missed periods. They can perform necessary evaluations, provide guidance, and address any underlying issues that may be contributing to the irregularity. It’s always better to seek medical advice to rule out any serious underlying causes and to ensure your overall health and well-being.


What Health Professional should you go to for missed periods?

For missed periods or irregular menstrual cycles, you can consult different healthcare professionals depending on your specific circumstances. Here are some options:

  1. Primary Care Physician (PCP): Your family doctor or primary care physician is often the first healthcare professional to consult for missed periods. They can perform an initial evaluation, discuss your medical history, and provide guidance on potential causes. They may refer you to a specialist if needed.
  2. Gynecologist: Gynecologists specialize in women’s reproductive health. If you’re experiencing missed periods, particularly if you have gynecological concerns or symptoms, a gynecologist is a great choice. They can perform a more in-depth evaluation, conduct relevant tests, and provide specialized care.
  3. Endocrinologist: If hormonal imbalances are suspected as the cause of missed periods, an endocrinologist is a specialist in hormone-related disorders. They can help diagnose and manage conditions like polycystic ovary syndrome (PCOS) or thyroid disorders that may be contributing to menstrual irregularities.
  4. Obstetrician: If you suspect pregnancy or are experiencing issues related to pregnancy or childbirth, an obstetrician, who specializes in pregnancy and childbirth, can provide guidance and care.
  5. Adolescent Medicine Specialist: For teenage girls who are experiencing irregular periods, an adolescent medicine specialist can provide specialized care and address concerns related to adolescent development.
  6. Reproductive Endocrinologist: If you’re struggling with fertility issues and irregular periods, a reproductive endocrinologist specializes in infertility and reproductive health. They can provide comprehensive evaluations and treatment options.
  7. Nurse Practitioner or Physician Assistant: In some cases, nurse practitioners or physician assistants can assess and provide guidance on missed periods. They often work closely with primary care physicians and gynecologists.

When seeking professional help for missed periods, it’s important to be prepared with information about your menstrual history, any accompanying symptoms, and your medical history. This will help the healthcare professional make an accurate diagnosis and recommend appropriate tests or treatments.

Ultimately, the choice of healthcare professional will depend on your specific situation, any underlying health conditions, and your individual preferences. If in doubt, starting with your primary care physician is often a good first step, as they can provide guidance and make referrals to specialists as needed.



Missed periods are a common occurrence with a wide range of potential causes, from pregnancy to stress and underlying medical conditions. While the occasional missed period may not be cause for alarm, persistent irregularities or the presence of concerning symptoms should prompt a visit to a healthcare professional. Seeking timely and appropriate medical care can help diagnose the root cause, alleviate any underlying issues, and ensure your overall well-being. Remember that understanding the reasons behind missed periods and addressing them can play a vital role in maintaining not only your reproductive health but your overall health and quality of life.
