Introduction
A 3 mm uterine cavity separation may be related to physiological or pathological factors. Common pathological causes include endometritis and incomplete abortion. Patients with these conditions typically present with clinical symptoms such as lower abdominal pain and increased vaginal discharge. The uterine cavity contains numerous glandular tissues that secrete a small amount of fluid, which helps buffer friction and irritation between the anterior and posterior walls of the uterus.

Separation of the uterine cavity measuring 3mm may be related to physiological or pathological factors. Common pathological causes include endometritis and incomplete abortion. Patients with these conditions typically present with clinical manifestations such as lower abdominal heaviness and pain, increased vaginal discharge, and others.

I. Physiological Factors

The female uterine cavity contains abundant glandular tissue that secretes a small amount of fluid to buffer friction and irritation between the anterior and posterior walls of the uterus. Therefore, in some women, factors such as excessive fatigue, sleep deprivation, or menstrual cycle fluctuations may enhance glandular secretion in this area, leading to a physiological enlargement of the uterine cavity space.

II. Pathological Factors

1. Endometritis

Inflammation affecting the endometrium can trigger an overactive immune response in capillaries, glands, and other tissues within the region. This stimulates the glandular tissue to secrete large amounts of fluid in defense against harmful microorganisms. Affected patients may consequently develop a uterine cavity separation of 3mm or more. As the disease progresses, most patients also experience additional symptoms such as dull lower abdominal pain, increased leukorrhea, and menstrual irregularities.

2. Incomplete Abortion

This condition results in retained embryonic tissue within the uterine cavity, increasing the risk of infectious inflammation in uterine tissues. The retained material increases the space between the anterior and posterior uterine walls, leading to uterine cavity separation of 3mm or more. Other signs and symptoms may include persistent lochia, lower abdominal heaviness and pain, and irregular vaginal bleeding.

Other diseases, such as endometrial cancer, may also cause similar presentations. If the aforementioned symptoms persist or worsen, patients are advised to seek timely medical evaluation at a hospital to determine the exact underlying cause and receive standardized treatment.
