What Causes Less Bleeding During Periods?

Lighter menstrual bleeding or Hypomenorrhea

Lighter menstrual bleeding, also known as hypomenorrhea, can have various causes. It’s important to note that what’s considered “normal” can vary from person to person, and factors like age, hormonal changes, and lifestyle can influence menstrual flow. Here are some common causes of lighter periods:

  • Pregnancy: One of the most common reasons for significantly lighter or absent periods is pregnancy. If you suspect you may be pregnant, take a pregnancy test.
  • Menopause: As women approach menopause, typically in their late 40s or 50s, their menstrual cycles become irregular and eventually stop. This results in lighter and less frequent periods until menopause is complete.
  • Birth Control Methods: Hormonal birth control methods like birth control pills, hormonal IUDs, and implants can lead to lighter periods. Some people use these methods specifically to reduce menstrual flow.
  • Polycystic Ovary Syndrome (PCOS): PCOS is a hormonal disorder that can cause irregular periods and often leads to lighter or less predictable bleeding.
  • Stress: High levels of stress can disrupt the menstrual cycle and cause lighter periods.
  • Low Body Weight: Being underweight or extreme weight loss can result in hormonal imbalances that lead to lighter periods.
  • Excessive Exercise: Intense or excessive physical activity, such as in the case of athletes, can affect the menstrual cycle and lead to lighter bleeding.
  • Certain Medical Conditions: Certain medical conditions, like thyroid disorders and pituitary gland disorders, can affect the hormonal balance and lead to lighter periods.
  • Certain Medications: Some medications, such as certain antidepressants and blood thinners, can cause changes in menstrual flow.
  • Menstrual Disorders: Conditions like Asherman’s syndrome (uterine scarring) or uterine fibroids can affect the uterine lining and cause lighter periods.
  • Perimenopause: The transitional period leading up to menopause, known as perimenopause, can cause changes in menstrual flow, including lighter periods.

It’s essential to keep in mind that if you experience a sudden and significant change in your menstrual flow or other concerning symptoms, it’s advisable to consult a healthcare provider. They can perform a thorough evaluation to determine the underlying cause and provide appropriate guidance and treatment if necessary.
