CRP (C-reactive protein) is a protein made by the liver. Its level rises quickly when there is inflammation in the body, for example during a cold, and falls again as it settles. Following CRP over time shows how it responds to everyday life and lifestyle changes.
A recent cold or infection, a small injury or very hard training can raise CRP for days to weeks. Smoking, short sleep, stress, body weight and a diet high in sugar and processed food also affect the level.
