A low BUN-to-creatinine ratio may be caused by a diet low in protein, a severe muscle injury called rhabdomyolysis, pregnancy, cirrhosis, or syndrome of inappropriate antidiuretic hormone secretion (SIADH).

If the kidneys are not functioning normally, high amounts of creatinine remain in the blood while low amounts are passed out in the urine. During a normal pregnancy, increased blood volume and kidney function cause an increase in the amount of creatinine filtered out of the blood and passed into the urine.

Causes. Most of the time, a high uric acid level occurs when your kidneys don't eliminate uric acid efficiently. Things that may cause this slow-down in the removal of uric acid include rich foods, being overweight, having diabetes, taking certain diuretics (sometimes called water pills) and drinking too much alcohol.

Hyponatremia (Low Level of Sodium in the Blood) In hyponatremia, the level of sodium in blood is too low. A low sodium level has many causes, including consumption of too many fluids, kidney failure, heart failure, cirrhosis, and use of diuretics. Symptoms result from brain dysfunction.

In patients with renal insufficiency, no creatinine level is an absolute contraindication to ACE inhibitor therapy. ACE inhibitors are not nephrotoxic.

A microalbumin creatinine ratio is most often used to screen people who are at higher risk for kidney disease. These include people with diabetes or high blood pressure. Identifying kidney disease at an early stage can help prevent serious complications.

A low BUN value may be caused by a diet very low in protein, malnutrition, or severe liver damage. Drinking excessive amounts of liquid may cause overhydration and cause a low BUN value. Women and children may have lower BUN levels than men because of how their bodies break down protein.

That said, creatine supplements should be approached with caution if you have a history of liver or kidney issues. SUMMARY Current research suggests that creatine does not cause liver or kidney problems.

If your creatine level increase is caused by a kidney issues, you may experience related symptoms. Kidney conditions often cause bladder and fluid retention issues. If your kidneys aren't working well enough to remove toxins and waste from your body, you could notice a wide range of symptoms, including: Nausea.

Generally speaking, high levels of creatinine can indicate that your kidneys aren't working well. There are many possible causes of high creatinine, some of which may be a one-time occurrence. Examples can include things such as dehydration or intake of large amounts of protein or the supplement creatine.

A high BUN value may be caused by a high-protein diet, Addison's disease, tissue damage (such as from severe burns), or from bleeding in the gastrointestinal tract. High BUN-to-creatinine ratios occur with sudden (acute) kidney problems, which may be caused by shock or severe dehydration.

Having high levels of creatinine is not life threatening, but it may indicate a serious health issue, such as chronic kidney disease. If a person has high creatinine levels due to a kidney disorder, a doctor will recommend treatment. Diet and lifestyle changes may also help.
