With age, women undergo several hormonal changes; however, one of the most noticeable changes in a woman is reduced menstrual flow. Here are a few reasons why period flow reduces with age. Tap to know!

Hormonal Changes

With age, the oestrogen and progesterone levels (key hormones responsible for menstruation) reduce, resulting in reduced blood flow.

Thyroid

Thyroid gland helps regulate hormones and metabolism. However, with age, thyroid issues like hyperthyroidism or hypothyroidism can lead to changes in blood flow.

Stress

Stress is also a common sign of reduced period blood flow, as it can affect the hypothalamus and disrupt the flow of periods.

Perimenopause

Light blood flow during periods is also a sign of perimenopause (when menopause is approaching). This factor can also lead to reduced flow.

Weight Fluctuations

Weight fluctuations can reduce period blood flow. Being overweight may cause reduced blood or irregular periods, while being underweight can lead to lighter flow.

Medical Conditions

With age, people might face medical issues, such as diabetes, which can also contribute to reduced menstrual blood flow.
