What is the reason for menstrual blood clots that look like meat?

Patient's question:

What is the matter if there are often meat-like blood clots in my menstrual blood? Is it okay? Is there any disease? Thank you

Doctor's answer:

When menstruation occurs with clots of blood in the menstrual fluid, it is referred to as "menstruation with clots." This condition often appears alongside other menstrual disorders and should be noted in clinical practice, not viewed in isolation.
Menstruation with clots is commonly caused by pathogenic mechanisms such as qi stagnation, cold congelation, qi deficiency, and heat scorching.
(1) Qi stagnation: Qi is the leader of blood; when qi flows, blood flows; when qi stagnates, blood coagulates. Emotional distress, liver qi stagnation, and impaired qi movement can lead to obstructed menstruation, resulting in clots.
(2) Cold congelation: "When the temperature is warm, blood flows smoothly; when the temperature is cold, blood coagulates," and "blood congeals into clots when exposed to cold." External cold pathogens, internal injury from cold, or a naturally deficient yang constitution with internal cold can cause cold to congeal in the (chong ren) channels, leading to menstruation with clots.
(3) Blood heat: External heat pathogens, excessive consumption of pungent and hot foods, overuse of warming uterine herbs, or emotional distress that transforms into internal heat can cause heat to accumulate in the channels. The blood is then scalded by heat, resulting in menstruation with clots.
(4) Qi deficiency: Excessive fatigue or prolonged illness depletes vital qi, weakening its ability to transport blood. Blood flow becomes sluggish, leading to stagnation and clot formation during menstruation.
