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

Muscle Weakness (Definition)

Muscle weakness is either a subjective or objective symptom based on history or formalized testing. As a result, any complaint of weakness needs to be correlated with testing that can bring out that weakness, which sometimes involves putting that muscle in an isolated and 'disadvantaged' scenario to assess adequately. Such weakness can have multiple etiologies from ...Read more

What could increased creatine kinase and aldolase levels indicate?

What could increased creatine kinase and aldolase levels indicate?

Likely muscle injury: Creatine kinase and aldolase would both be elevated after a muscle injury. Ck can also be elevated in kidney failure. Adolase can be sub-classified into a, b and c which helps differentiate from which tissue the high levels came. ...Read more

What causes CPK levels in the 5000 range and what problems would it cause?

What causes CPK levels in the 5000 range and what problems would it cause?

Lots of causes: Elevated CPK indicates muscle damage and can be resolving or ongoing. There are many causes of this, but the main issue is that it can lead to kidney failure since the muscle breakdown proteins aren't filtered well by the kidneys. Also, ongoing muscle damage can lead to compartment syndrome, a surgical emergency. ...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

Can a charley horse cause your CPK level to be elevated?

Can a charley horse cause your  CPK level to be elevated?

Muscle enzyme: CPK elevations are seen in muscle disease, acute cardiac events, muscle trauma (rhabdomyolysis) but also, in weight lifters, and marathon runners. So, can be rather serious or benign. Perhaps, a severe localized cramp could cause enough muscle trauma to raise the level modestly, but, if significantly up, need to test further and uncover the etiology. ...Read more

Why do I have extreme high levels of ck (skeletal muscle enzymes) be the result of?

Why do I have extreme high levels of ck (skeletal muscle enzymes) be the result of?

CPK: Creatine (phospho)kinase. This enzyme will be elevated generally in disorders that injure muscle or when muscles are not working right. Extremes of exercise or injury can cause this, as can disorders of the muscles themselves, some hereditary. There are other forms of the enzyme that can come from other parts of the body, so this should be evaluated by a practitioner. ...Read more

Can heart failure or low cardiac output be associated with protein deficiency and how to best recover? Bnp=300 & protein 5.8g/dl

Can heart failure or low cardiac output be associated with protein deficiency and how to best recover? Bnp=300 & protein 5.8g/dl

Heart failure : Right sided hf can lead to swelling of intestines and then poor nutrient absorption. This can go along with abdominal bloating. If this is happening or if you have difficulty breathing with exercise, you need more water taken off. I like to use (lots of) Aldactone (spironolactone) for this. Also check to see if you are losing protein in your urine. ...Read more

How to keep CPK muscle enzymes down low levels?

Why are they high: Creatine phosphate kinase enzymes are high from the breakdown of skeletal muscle or heart disease if you are getting a lot of exercise take a rest and the levels will come down as your muscles regenerate if it is due to myositis venue need anti-inflammatory or steroid treatment you should consult your rheumatologist if it is it it if it is from a single heart myocardial infarction it will go down in several days. ...Read more

What causes EPO level to drop. Can it be something not serious. Kidneys scan and ceatinine level in blood normal. Got moderate anemia. Epo low. 70 yrs?

Anemia in a 70'er: The 70 year old person likely has chronic kidney disease (CKD), despite having a normal level creatinine. Have that person see a nephrologist for a 24 hour urine for creatinine clearance to assess the person's kidney function. It the glomerular filtration rate (GFR) is ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
