Uterine fibroids detected at 45 days of pregnancy require a comprehensive judgment based on the location and size of the fibroids. Depending on the etiology, some patients can continue their pregnancy without special treatment at first. However, they should go to the hospital regularly for maternity checkups and seek medical treatment once abnormalities are detected. Common causes and possible consequences 1. 45 days of pregnancy is the early stage of pregnancy, if the fibroid is a subplasma fibroid, it usually only causes pressure symptoms and does not have much effect on pregnancy, so pregnancy can usually continue; 2. If the fibroid increases under the effect of estrogen and progesterone, it may lead to miscarriage, premature birth and other adverse consequences, commonly seen in interstitial fibroids. In general, pregnancy can be continued, but timely obstetric examinations are needed to observe changes in the myoma, maternal health, and embryonic development. Medication or surgical removal is usually not recommended during pregnancy to avoid affecting fetal growth and development. However, if the fibroids increase in size and become red and degenerate, causing fever and abdominal pain, triggering preterm abortion and intrauterine distress, you need to go to the hospital for treatment in a timely manner. In addition, pregnant women should avoid foods with high estrogen content such as soy products and soy beans, and develop good work and diet habits, pay attention to rest, avoid staying up late, straining and overeating.
