Introduction
In general, passing a large clot of blood and tissue during menstruation may be related to normal physiological phenomena, natural variations in menstrual flow, endometrial hyperplasia, endometriosis, uterine fibroids, or other factors. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a healthcare provider. Patients are advised to maintain good personal hygiene and keep warm during menstruation, which may help alleviate symptoms.

Generally, the presence of a large piece of bloody tissue during menstruation may be related to normal physiological phenomena, natural variations in menstrual flow, endometrial hyperplasia, endometriosis, uterine fibroids, and other factors. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a physician. Specific analyses are as follows:

1. Normal Physiological Phenomenon

During menstruation, the endometrial lining sheds cyclically and is expelled from the body along with menstrual blood. Sometimes, larger pieces of shed endometrial tissue may form clots resembling chunks of tissue. This is a normal physiological process and generally does not require excessive concern.

2. Natural Variations in Menstrual Flow

Menstrual volume and consistency vary among women. In some cases, heavier or thicker menstrual flow may lead to the formation of larger blood clots. It is advisable to maintain healthy lifestyle habits and avoid excessive fatigue.

3. Endometrial Hyperplasia

Endometrial hyperplasia may be associated with hormonal imbalances, long-term use of estrogen-containing medications, genetic factors, and others. Insufficient secretion of fibrinolytic enzymes may prevent complete breakdown of the endometrium during the secretory phase, and combined with excessive endometrial proliferation, this can result in the shedding of large endometrial fragments, forming blood clots. Symptoms may include prolonged menstrual cycles and increased menstrual flow. Under medical supervision, medications such as norethisterone tablets, progesterone capsules, or dydrogesterone tablets may be used to alleviate symptoms.

4. Endometriosis

Endometriosis refers to the growth of endometrial tissue outside the uterus and may be related to immune function, genetic, and environmental factors. During the menstrual cycle, this ectopic tissue bleeds but the blood cannot be discharged normally, leading to the formation of cysts or scar tissue. When expelled, it may appear as blood clots. Common symptoms include dysmenorrhea (painful periods), pain during intercourse, and infertility.

5. Uterine Fibroids

Uterine fibroids are benign tumors arising within the muscular wall of the uterus and may be linked to genetic predisposition, sex hormone levels, and dysfunction of stem cells. Fibroids can compress the endometrium, impairing its normal function, leading to increased menstrual flow and changes in texture, potentially resulting in larger blood clots. Symptoms may include irregular menstrual cycles, abdominal pain, and frequent urination. Treatment may include medications such as Guizhi Fuling Capsules, Hongjin Xiaojie Capsules, or Danbie Capsules, as directed by a physician.

Patients are advised to maintain good personal hygiene, stay warm during menstruation, and avoid consuming spicy or irritating foods, which may help alleviate symptoms.
