Myoma: What to Know About Fibroids During Pregnancy - Obstetrics and Gynecology

More Info

---

Fibroids, also known as uterine leiomyomas, are non-cancerous growths that develop in or on the uterus. They are quite common, especially among women of reproductive age, and can vary in size from very small to large masses. Understanding fibroids during pregnancy is crucial, as they can impact both the mother and the developing fetus in various ways.

1. What are Fibroids?
Fibroids are made up of muscle and fibrous tissue and can be classified based on their location: intramural (within the uterine wall), subserosal (on the outer surface of the uterus), and submucosal (just beneath the lining of the uterus). The 2 cm fibroid you mentioned is relatively small and may not cause significant issues during pregnancy. However, their growth can be influenced by hormonal changes, particularly estrogen, which can lead to increased size during pregnancy.

2. Symptoms and Concerns:
While many women with fibroids experience no symptoms, some may have heavy menstrual bleeding, pelvic pain, or pressure symptoms. During pregnancy, fibroids can sometimes cause discomfort, especially if they are large or if they are located in a position that puts pressure on surrounding organs. The pain you experienced during your menstrual cycle could be related to the fibroid, but it is also common for women to experience cramping and discomfort during early pregnancy due to the stretching of the uterus.

3. Location Matters:
You mentioned that the fibroid is located outside the uterus, which is referred to as a subserosal fibroid. These types of fibroids are less likely to interfere with pregnancy than those located within the uterine cavity. However, they can still cause discomfort or pain, especially as the uterus expands. If the fibroid is large, it may also contribute to a feeling of fullness or pressure in the abdomen.

4. Impact on Pregnancy:
Most women with fibroids have normal pregnancies and healthy babies. However, there are some potential complications associated with fibroids during pregnancy, including:
- Pain: As the uterus grows, fibroids can become more painful, especially if they outgrow their blood supply and undergo degeneration.

- Preterm Labor: In some cases, fibroids can lead to preterm labor, although this is not common.

- Placental Issues: If a fibroid is located near the placenta, it may increase the risk of placental abruption or previa.

5. Monitoring and Management:
It is essential to have regular prenatal check-ups to monitor the fibroid's size and any symptoms you may experience. If the fibroid causes significant pain or complications, your healthcare provider may recommend pain management strategies or, in rare cases, surgical intervention. However, surgery during pregnancy is typically avoided unless absolutely necessary.

6. Emotional Well-being:
It’s understandable to feel anxious about the presence of fibroids during pregnancy, especially if you are experiencing discomfort. Open communication with your healthcare provider is vital. They can provide reassurance and help you understand the implications of fibroids on your pregnancy.
In summary, while fibroids can be a source of concern during pregnancy, many women with fibroids go on to have healthy pregnancies and deliveries. It’s crucial to stay informed, maintain regular prenatal care, and discuss any symptoms or concerns with your healthcare provider to ensure the best possible outcome for you and your baby.
