Women who have been diagnosed with liver hemangiomas face a risk of complications if they become pregnant. The female hormone estrogen, which increases during pregnancy, is believed to cause some liver hemangiomas to grow larger.
Rarely, growing hemangioma can cause signs and symptoms that may require treatment, including pain in the upper right quadrant of the abdomen, abdominal bloating or nausea. Having a liver hemangioma doesn't mean you can't become pregnant. However, discussing the possible complications with your doctor can help you make a more informed choice.
Medications that affect hormone levels in your body, such as birth control pills, could cause complications if you've been diagnosed with a liver hemangioma. But this is controversial. If you're considering this type of medication, discuss the benefits and risks with your doctor.
