What causes elevated bun/creatinine ratio?

What causes elevated bun/creatinine ratio?

Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body.
Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible. ...Read more

What causes elevated bun/creatinine ratio?

What causes elevated bun/creatinine ratio?

Many causes: Blood tests called BUN (blood urea nitrogen) and cr (creatinine) are often checked to help evaluate kidney function. The normal bun/cr ration is about 10:1 to 15:1. Some of the more common causes of an elevated bun/cr ratio are: dehydration, GI bleeding, increased protein intake, small amount of muscle mass, increased muscle breakdown. ...Read more

Varying creatinine: I have a question, why is your physician checking your serum creatinine (c) levels so frequently? You are 32 years old and your c levels appear to be elevated. Do you have any chronic kidney disease? If not, variations of c can be caused by dehydration, among other things. I suggest you speak to your physician (p) and get the p input. He knows you best and can give you a meaningful answer. ...Read more

What the causes of elevated creatinine with normal urea? And causes of increase urea with normal creatinine?

Homework?: This is more than we can handle in 400 words, you know reference ranges are set so several % of healthies fall outside, that all well-muscled men have "high creatinine" and that labs mean nothing apart from people. This said, (1) healthy bodybuilder, people on Bactrim (sulfamethoxazole and trimethoprim) or Tagamet, others; (2) dehydration, after big steak dinner. Try to understand the basic biology instead of just lists. ...Read more

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your results are normal, including creatinine clearance. ...Read more

What causes an elevated bun/creatinine ratio on your lab results?

Dehydration: Is most common cause of high BUN with normal creatinine (therefore high ratio). Other causes can be high protein load in the diet, muscle injury or muscle breakdown (bun is formed by the breakdown of proteins). Whether to worry depends on how high the BUN is, and the circumstances when the test was drawn. Talk to the doctor who ordered the test for personalized interpretation. ...Read more

Dx'd with 2 bouts of idiopathic pancreatitis. No cause found. I've had no pain at all. How then, can it be pancreatitis? I had elevated lypase and amalyse. I have CKD 3, egfr 46 and creatinine of 1.3.

Unusual to have: Pancreatitis with no pain. If alcohol, medication, gallstones, trauma, elevated triglycerides have been excluded as cause of your pancreatitis, then it sometimes becomes idiopathic, fancy word for unknown cause. You need to have a specialist look at your case. ...Read more

In CKD can increasing exercise or losing weight cause an elevation in serum creatinine?

Yes: If exercising more you may become more dehydrated and this can further damage your kidneys. Weight changes should not unless breakdown products of protein build up again from not hydrating adequately, please see your doctor to discuss treatment to prevent further damage to your kidneys as soon as possible. ...Read more

Persistent Bloating from 3 month, increased when eating dairy products, Lost 12kgs in 4month? Creatinine increase to 1.4. What is cause of weight loss?

Persistent Bloating from 3 month, increased when eating dairy products, Lost 12kgs in 4month? Creatinine increase to 1.4. What is cause of weight loss?

Dunno but...: With an unplanned weight loss of 12 kg over the course of just 4 months, that portends probably a very serious illness. Also, the high serum creatinine argues for deteriorating kidney function. You need a thorough workup to find out what is going on in your body. Do not delay! ...Read more

Had bloodwork done. Bun/creatinine ratio, ldh little elevated. Hdlcholesteral a little low. Everything else norm. Can smoking and obese cause this?

Had bloodwork done. Bun/creatinine ratio, ldh little elevated. Hdlcholesteral a little low. Everything else norm. Can smoking and obese cause this?

Yes: Smoking and obesity can cause that cholesterol pattern. The elevated ldh is a little unusual; all labs need to be evaluated further by your physician- depends on many things.
These findings do provide objective evidence for lifestyle modifications needed to start now, so that cardiologists or cardiac surgeons are not needed in the future.
Stop smoking, start exercise- goal 30-45min 5-6 days/wk. ...Read more

My mother had a heart attack on friday. Can that cause an elevated creatinine level? She also went into dka, could that cause it?

My mother had a heart attack on friday. Can that cause an elevated creatinine level? She also went into dka, could that cause it?

No surprise: Not knowing what her creatinine is at usual baseline, years of diabetes can damage kidneys so this could be the result of her diabetes. She is very ill. Without knowing details, poor blood circulation because of heart attack and DKA could cause kidney damage that can sometimes improve, tho I don't know your mom's case. Dehydration cause could improve with hydration. Hope she quickly recovers. ...Read more
