Can myeloma cause blood in your stool?
Myeloma itself doesn't typically cause blood in your stool directly. However, myeloma can affect your platelet count, which may lead to bleeding issues.
When myeloma damages your bone marrow, it can lower the number of platelets in your blood, a condition called thrombocytopenia. This can cause abnormal bleeding, though this is uncommon. The bleeding that occurs typically shows up as:
* Nosebleeds
* Bleeding from the gums
* Easy bruising
* Heavy bleeding from minor cuts
If you're noticing blood in your stool, it's important to contact your healthcare provider right away. While it may not be directly related to myeloma, any unusual bleeding should be evaluated, especially since some myeloma treatments can also affect your blood's ability to clot properly.
Your doctor can order blood tests to check your platelet levels and determine what's causing the bleeding.
