What could be causing bloating in the upper abdomen with polycythemia vera?
Bloating in your upper abdomen with PV is often related to an enlarged spleen, a condition called splenomegaly. This happens in about 75 percent of people with PV.
When your bone marrow can't keep up with making healthy blood cells, your spleen steps in to help produce them. As it takes on this extra work, it grows larger and can press against your stomach and nearby organs.
This pressure can make you feel:
- Bloated and full, even after eating small amounts
- Discomfort or pain in your upper left abdomen
- Loss of appetite
- Nausea
However, abdominal discomfort can also come from other health conditions unrelated to your MPN, like acid reflux or irritable bowel syndrome.
It's important to talk with your healthcare provider about your symptoms. They can determine whether your spleen is enlarged and recommend appropriate treatments to help shrink it and relieve your discomfort. There are medications and other options available that can improve your quality of life.
