How Uterine Fibroids Can Affect Each Trimester of Pregnancy
If you have uterine fibroids and are pregnant, you may wonder how they could affect your pregnancy and delivery. Many women with fibroids have healthy pregnancies without major complications. However, some fibroids may cause pain or be associated with pregnancy complications, depending on their size, number and location. Fibroid growth during pregnancy varies, and not all fibroids increase in size. Regular antenatal care and individual assessment by your obstetrician can help guide monitoring and delivery planning.
Uterine fibroids, also called leiomyomas, are non-cancerous growths that develop in or around the uterus. Many fibroids do not cause symptoms, and most women with fibroids do not experience major pregnancy complications. Fibroid behaviour during pregnancy varies: some may grow, particularly in early pregnancy, while others remain stable or become smaller. Hormonal changes may influence fibroid growth, but enlargement is not inevitable. The effect of a fibroid on pregnancy depends partly on its size, number and location, including whether it distorts the uterine cavity or lies near the placenta.
Women who have uterine fibroids during pregnancy should discuss them with their obstetrician. Treatment is not usually required solely because fibroids are present, but the doctor may recommend monitoring based on the fibroids’ size, location, symptoms and the progress of the pregnancy. Management and delivery planning should be individualised. The following sections explain possible concerns during each stage of pregnancy.
First Trimester:-
Some uterine fibroids may increase in size during early pregnancy, although growth patterns vary from person to person. Possible concerns include abdominal or pelvic pain and, in some cases, pregnancy complications. Research on the relationship between fibroids and miscarriage is mixed, and many women with fibroids experience normal pregnancies. Individual risk depends on clinical factors, including the fibroids’ size and location.
Pelvic or abdominal pain may occur during pregnancy in women with fibroids. Pain can be associated with changes within a fibroid, including degeneration, and may depend on its size and location. Severe, persistent or worsening pain should be assessed promptly by a healthcare professional rather than assumed to be caused by a fibroid.
Vaginal bleeding during early pregnancy can have several causes and should not automatically be attributed to fibroids. The relationship between a fibroid and the placenta may be relevant to pregnancy management, so any bleeding should be discussed promptly with an obstetrician. Heavy bleeding, severe abdominal pain, dizziness or fainting requires urgent medical assessment.
Miscarriage can occur in any pregnancy, but having fibroids does not mean that pregnancy loss will occur. The available evidence on miscarriage risk in women with fibroids is mixed. Your obstetrician can explain your individual circumstances and advise on appropriate monitoring.
Second and Third Trimester:-
During the second and third trimesters, some women with fibroids may experience abdominal pain or require additional assessment of the baby’s position, growth and the placenta. Fibroids are associated with an increased risk of preterm birth in some studies, although outcomes vary. Fibroids may also affect the mode of delivery when their size or location interferes with the baby’s position, labour or the birth canal. A Caesarean delivery is not necessary for every woman with fibroids; the decision depends on individual obstetric findings.
Fibroid-related pain may occur at different stages of pregnancy and can sometimes be severe, particularly when a fibroid undergoes degeneration. Large fibroids may also cause pressure symptoms, depending on their location. Severe or persistent pain needs medical assessment to identify the cause and determine appropriate treatment.
Placental abruption occurs when the placenta separates from the wall of the uterus before the baby is born. It can reduce the baby’s oxygen supply and cause serious bleeding in the mother. Some studies have reported an association between uterine fibroids and placental abruption, but the evidence is not uniform. Severe abdominal pain, vaginal bleeding or other concerning symptoms during pregnancy require urgent medical assessment.
Preterm birth means that a baby is born before 37 completed weeks of pregnancy. Research suggests that uterine fibroids may be associated with an increased risk of preterm birth, although many women with fibroids deliver at term. The presence of fibroids does not mean that early labour will occur. Your obstetrician can advise whether additional monitoring is appropriate based on your pregnancy and individual risk factors.
Women with uterine fibroids may have a higher likelihood of Caesarean delivery in some circumstances, particularly when a fibroid obstructs the birth canal, affects the baby’s position or contributes to difficulties during labour. However, many women with fibroids can deliver vaginally. A Caesarean delivery should be recommended according to the individual clinical circumstances and standard obstetric indications, rather than solely because fibroids are present. Your obstetrician will discuss the potential benefits and risks of each delivery option.
