What is Amenorrhea and Its Causes
Neftaly Health & Wellness
Amenorrhea is the medical term for the absence of menstruation — when a person of reproductive age misses one or more periods. While sometimes temporary and harmless, amenorrhea can also signal underlying health issues that need attention.
At Neftaly, we want to help you understand what amenorrhea is, why it happens, and when to seek medical advice.
What is Amenorrhea?
There are two main types of amenorrhea:
- Primary Amenorrhea: When a person has not started menstruating by age 15 or within 3 years of breast development.
- Secondary Amenorrhea: When someone who has previously had normal periods stops menstruating for three months or more (or six months if irregular cycles).
Common Causes of Amenorrhea
1. Pregnancy
The most common cause of missed periods is pregnancy.
2. Hormonal Imbalances
Issues with hormones that regulate the menstrual cycle, such as thyroid disorders, polycystic ovary syndrome (PCOS), or problems with the pituitary gland.
3. Excessive Exercise or Low Body Weight
High levels of physical activity or very low body fat can disrupt hormone production and stop periods.
4. Stress
Severe emotional or physical stress can affect the brain’s signals to the reproductive system, leading to missed periods.
5. Medications
Certain medications, including hormonal contraceptives, antidepressants, and chemotherapy drugs, can cause amenorrhea.
6. Structural Issues
Problems with reproductive organs, such as congenital abnormalities, scarring, or blockage, can prevent menstruation.
7. Menopause or Premature Ovarian Failure
Menopause naturally ends menstruation, but early menopause or ovarian failure can cause amenorrhea before age 40.
When to See a Doctor
Seek medical advice if you:
- Have not started menstruating by age 15
- Miss three or more periods in a row and are not pregnant
- Experience other symptoms like pelvic pain, excessive hair growth, or sudden weight changes
Early diagnosis and treatment can help address underlying causes and support your reproductive health.
