C-reactive protein (CRP) is found in the blood and is a response to inflammation in the body. It can also be an indicator of the presence of infection, trauma or serious illness. Chronic inflammation can keep CRP levels elevated, which can increase the risk of cardiovascular conditions such as heart attacks or stroke.
Some studies suggest that C-reactive protein levels rise as blood sugar levels rise. Elevated CRP is also thought to be associated with metabolic syndrome.
