Severe infection (septic shock): Septic shock can occur when bacteria leave the original site of an infection (most often in the lungs, abdomen or urinary tract) and enter the bloodstream. The bacteria then produce toxins that affect blood vessels, leading to a profound and life-threatening decline in blood pressure.
Why does infection decrease blood pressure?
Sepsis occurs when toxins produced by certain bacteria cause cells in the body to release substances that trigger inflammation (cytokines). Although cytokines help the immune system fight infection, they can have harmful effects: They can cause the blood vessels to widen (dilate), decreasing blood pressure.
How does infection affect blood pressure?
Infections do have a connection to inflammation and heart disease. Infections elevate c-reactive protein (CRP) levels, an antibody-like protein. Increased CRP levels promote atherosclerosis (hardening of the arteries) and can lead to high blood pressure.
What kind of infection can cause low blood pressure?
