What is the cause of heavy menstrual flow and light color?

Women begin menstruating at age 13, and this lasts about thirty years. Due to the different physical constitutions of women, menstrual patterns may not be the same, but they are relatively stable. However, in some cases, many women experience heavy and light-colored menstruation and are very worried and want to find the cause. So, what is the reason for heavy menstrual flow and light color? Let’s take a closer look below.

Generally speaking, diseases that cause irregular menstruation in women are seen in ovarian diseases and cervical diseases. Menstruation is formed after the hormones secreted by the ovaries stimulate the endometrium. The hormones secreted by the ovaries are controlled by the release of hormones from the pituitary gland and hypothalamus. Therefore, any abnormality in the function of the ovaries, pituitary gland, or hypothalamus will affect menstruation. There are two main reasons for irregular menstruation, small amount of menstrual flow and dark color:

1. Caused by neuroendocrine dysfunction: mainly due to unstable or defective function of the posterior brain-pituitary-ovarian axis, that is, menstrual disorder.

2. Caused by organic diseases or drugs, including local inflammation of reproductive organs, tumors and developmental abnormalities, malnutrition, intracranial diseases, other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, liver diseases, blood diseases, etc. Menstrual irregularities may occur in women who use psychiatric drugs, endocrine preparations, or intrauterine devices for contraception.

The above is an introduction to the situation of heavy menstrual flow and light color. Women should be clear about it. There are many factors that cause women to have heavy and light menstrual flow, most of which are caused by abnormal conditions in the body. Therefore, after discovering that the menstrual flow is heavy and light in color, it is best to find out the cause and provide targeted treatment to avoid harm to the patient's health.
