The causes of elevated estrogen levels in women’s bodies are as follows: 1. Frequent use of estrogenic drugs, such as birth control pills, can cause exogenous estrogen to enter the body and increase estrogen. 2. Special diseases of the ovaries, such as ovarian granulosa cell tumors, which have the function of secreting estrogen, can lead to a significant increase in estrogen levels in the patient’s body. 3. Pregnant women, after pregnancy, can experience a significant increase in estrogen and progesterone levels, which is a physiological reaction. 4. Women who are overweight will secrete more estrogen and have higher estrogen levels due to the thick subcutaneous fat layer. 5. Patients with serious liver diseases, such as active hepatitis, cirrhosis and liver cancer, will also have higher estrogen levels due to the reduced ability of liver cells to metabolize estrogen.
