What happens when kreatins are low?

Hi there, are you sure that you aren't talking about creatinine? I think that's what you mean to be talking about because I can't find anything on kreatins so unless I'm wrong about creatinine, here's your answer. They're associated with kidney function, so I can tell you that if the level of creatinine in the blood is low then there may be an issue with your kidneys. Did you get a blood test? Is that the case or is there something else at play here? Please let me know how you're doing okay? :-)
