When fibroids are large, they cause the abdomen to become larger and look like a fat belly. Uterine fibroids are composed of smooth muscle and connective tissue, and their occurrence may be related to estrogen. When the fibroids are small, no lumps can be felt in the lower abdomen or there are no obvious symptoms, but with the gradual increase of uterine fibroids, both the lower abdomen and the uterus can be found in the abdomen, as well as a substantial lump, and it looks like a small abdominal fat. After the occurrence of fibroids, the most common symptoms are increased menstrual flow and prolonged menstrual period, which may also cause increased leukorrhea or pressure symptoms, leading to urinary difficulties, frequent urination and other manifestations. When uterine fibroids are diagnosed and asymptomatic, no treatment is usually needed; if you have symptoms, consult a doctor and follow the doctor’s instructions.
