What causes creatinine kinase levels to rise with muscle weakness?

What causes creatinine kinase levels to rise with muscle weakness?

Damage to muscle: The correct term is creatine kinase (ck). Creatinine is something else. Useful to know: most "muscle" weakness is actually caused by nerve, not muscle, malfunction. True muscle weakess: myocytes (muscle cells) contain lots of the enzyme ck. Low levels are found in blood normally. Damage to myocyte cell membranes from a variety of causes causes leakage of ck into the blood. Recovery->normalization. ...Read more

I have a blood value for creatinine kinase of 298 u/l. Is that unhealthy or is it normal when doing workouts a few times a week?

I have a blood value for creatinine kinase of 298 u/l.  Is that unhealthy or is it normal when doing workouts a few times a week?

Creatinine kinase: This is okay as long as you don't have severe pain. Ck is considered significant when the value is 10 times upper limit of normal. ...Read more

Creatine kinase vs creatinine, is there a difference between them?

Yes: Creatine kinase is a muscle enzyme that is measured to assess heart damage (the mb isoenzyme form) or skeletal muscle damage (the mm isoenzyme). Creatinine is an endogenous peptide, present in everyone, that is cleared by the kidneys and is measured in clinical practice to estimate kidney function. ...Read more

Bun is 28, creatinine 1.16. Egfr 61. Healthy 35 yr old caucasian female. Only problem is benign fasciculations x1 year. Normal creat kinase. Why?

Stop worrying: I am going to assume that you feel well and are asking why your estimated GFR is lowish and your BUN a bit high. I like to eat protein and my BUN is always high. Are you athletic? When i was lifting daily my creatinine was 1.6-1.7; or a Motrin tablet or minimal kidney disease may be raising yours. I suggest repeat in a year and stop fretting over a number in the meantime. ...Read more

Collar bone pain, swelling. X-ray, CT scan nl. Labs for sed rate, cpk, creatinine kinase, CBC all nl. Pcp, pain dr stumped. Any ideas or suggestions?

Collar bone pain, swelling. X-ray, CT scan nl. Labs for sed rate, cpk, creatinine kinase, CBC  all nl. Pcp, pain dr stumped. Any ideas or suggestions?

Do you lift weights?: If you lift weights (benchpress), that might be the culprit. The muscles and ligaments that attach to the collarbone are shown in the diagram. If your pain is at one of these places, you likely have a strain from lifting. If you've fallen on your outstretched arm, the same thing can happen. Also, ask your doctor about osteonecrosis (dying bone due to lack of blood supply). Hope that helps! ...Read more

Normal white count and a high level of creatine kinase. What illness could this indicate?

Normal white count and a high level of creatine kinase. What illness could this indicate?

Maybe none: If you exercise, you ck can be very high -- many times the upper limit of normal. The normal range is for couch potatoes. I'm glad you asked, but no lab test means much in isolation. Best to ask your physician and see what matches with your symptoms and lifestyle. ...Read more

How to treat high level of creatine kinase due to nerves?

How to treat high level of creatine kinase due to nerves?

Here's accurate info: Somebody's kidding you or there is a misunderstanding. Creatine kinase is an enzyme found in the blood; the reference range was determined for couch potatoes, and in my series' of athletic medical students, a majority of healthy young people have "elevated levels" just from exercising. It's also high in a few illnesses your physician knows about, but not from "nerves". ...Read more

How long would creatine kinase (ck) levels in blood be elevated after exercise?

How long would creatine kinase (ck) levels in blood be elevated after exercise?

Up to four days: Strenuous exercise frequently triggers a rise in ck that peaks 16 to 24 hours following a workout, then stays elevated for 72 hours before falling back to. ...Read more

What disease has normal white count and hi creatine kinase?

What disease has normal white count and hi creatine kinase?

Being athletic: The reference range for creatine kinase is set based on the assumption that you do not exercise. In my series of medical students, all the men and the majority of the women who lead even moderately fitness-focused lifestyles have high creatine kinase -- often very high. If you're healthy and are working your muscles, be proud of yourself and keep doing what you're doing. ...Read more

What are the symptoms of high creatine kinase?

What are the symptoms of high creatine kinase?

None: In my series of medical students, almost all the men and a majority of the women who were even moderately focused on physical fitness had creatine kinase levels above reference range. Right or wrong, the lab's reference range assumes the person does not exercise. ...Read more

Can you still workout hard if creatine kinase is high?

Can you still workout hard if creatine kinase is high?

Resolve cause first: High creatine kinase is due to muscle damage. It would be important to determine the cause of muscle damage before working out so that you do not add to the damage. ...Read more
