Hi Sumathi, Welcome to HCM, I have read your query, the uterus is a pear-shaped muscular organ that measures roughly about 7.5cm in the non-pregnant state. The uterus is not usually palpable, or felt, as it sits behind the bones of the pelvis. Certain conditions lead to the enlargement of the uterus beyond its hiding place, making it possible sometimes to feel it in the lower part of the abdomen as an abdominal mass. Fibroids as the most common benign growths of the uterus, arising from the musculature of the uterus. They can grow as large as a full-term pregnancy, distorting the normal anatomy of the uterus and sometimes disrupting normal menstrual rhythm. They are typically classified according to their position in the walls of the uterus. All kinds of fibroids have the potential of causing an enlargement of the uterus. Endometriosis is the transplanting of pockets of the lining of the uterus, the endometrium, onto sites outside the cavity of the uterus. When this affects the walls of the uterus, it is called adenomyosis. With successive menstrual cycles, these pockets swell with menstrual fluid, causing the uterus to enlarge. Gestational trophoblastic disease, also known as molar pregnancy, also leads to enlargement of the uterus. The condition is due to an abnormal development of fetal tissue and is characterized by sudden uterine enlargement. The enlargement is usually faster than that of a normal pregnancy. According to the National Institutes of Health, it is more common before the age of 16 years and after the age of 40 years. Uterine cancer is typically seen in older women after the onset of menopause. The most common type usually arises in the lining of the uterus, the endometrium. The usual presentation is bleeding from the vagina after established menopause. It also causes uterine enlargement. Cervical cancer, cancer arising where the uterus opens into the vagina, also leads to uterine enlargement, either by its bulk or by blocking menstrual flow and swelling up the uterus with the backflow. Will recommend to kindly show to your physician or gynaecologist to address the underlying cause. Thanks
