Is It Normal to Have a Lump in the Stomach While Pregnant?

It can be normal to notice a lump in your stomach during pregnancy, but any new lump should be checked by your doctor to make sure it’s harmless.

Explanation

During pregnancy, your body goes through many changes that can cause lumps or masses in the abdominal area. In some cases, these lumps are harmless, such as those from the extra fluid or growth of tissues due to increased blood flow and hormonal changes. For example, benign abdominal wall masses may form and sometimes even cause discomfort. In rare cases, a painful or growing mass might require further evaluation or treatment during pregnancy. Medical professionals may use safe imaging tests to look at the lump without harming you or the baby. Although many lumps in the stomach area during pregnancy turn out to be non-serious, it is important to report any new or changing lumps to your healthcare provider. They can perform an examination and decide if any further steps are needed. Keeping track of such changes helps ensure that both you and your baby stay healthy throughout the pregnancy.
