Why Does Menstrual Blood Have Stringy Texture?

Under normal circumstances, women may experience slight threadiness during menstruation. However, some women may experience menstrual threadiness that is not considered a normal physiological phenomenon, which may be influenced by other factors. Therefore, in such cases, it is necessary to observe not only the menstrual threadiness but also whether there are any other abnormal changes in menstruation. By combining specific manifestations, we can judge the reasons. So, what causes menstrual threadiness? Here are some possible explanations:

Viscous menstrual threadiness may be a normal physiological phenomenon, mainly influenced by changes in hormone secretion levels such as estrogen and progesterone. The amount and state of vaginal discharge may change accordingly, resulting in increased secretion and a viscous consistency. After menstruation begins, pelvic congestion may occur, accompanied by viscous threadiness.

Significant emotional fluctuations, such as frequent irritability or persistent feelings of depression, sadness, and anxiety, can affect menstruation. Under such conditions, symptoms of viscous menstrual threadiness may appear, but they may gradually resolve as emotions stabilize.

PCOS is a common factor leading to viscous menstrual threadiness, closely related to endocrine disorders. Once PCOS is diagnosed, the ovaries undergo cystic changes, and the function of the hypothalamus-ovarian axis is affected, resulting in abnormal menstrual responses.

Gynecological inflammatory diseases such as endometritis or pelvic inflammatory disease can lead to not only abdominal pain and abnormal vaginal discharge but also menstrual disorders. A common symptom is viscous menstrual threadiness. It is recommended to promptly take anti-infective medication.

Severe conditions such as endometrial cancer, ovarian cysts, and severe cervical erosion can often cause viscous menstrual threadiness. Additionally, conditions such as hyperthyroidism, diabetes, and other metabolic disorders may also be responsible. Therefore, it is crucial to undergo abdominal ultrasound examinations and seek professional treatment after diagnosis.
