What is a dangerous high BUN level in blood?
A study shows that patients with elevated BUN (> 20 mg/dl) have an increased risk of infection [6].
Is a BUN of 28 high?
In general, non-renal causes usually increase BUN mildly, usually to less than 28 mg/dL. In comparison, patients with end-stage renal failure, requiring renal replacement therapy, may have plasma BUN levels greater than 140 mg/dL.
What does a BUN of 50 mean?
A BUN of 50 to 100 mg/100mL suggest serious renal impairment, and a BUN of 150 to 250 mg/100 mL is virtually diagnostic of severe glomerular dysfunction. In a steady state, a 50\% decrease in the glomerular filtration rate (GFR) will result in a doubling of the BUN.
Is a BUN of 35 bad?
General reference ranges for a normal BUN level are as follows: Adults up to 60 years of age: 6-20 mg/dL. Adults over 60 years of age: 8-23 mg/dL.
Is a BUN level of 32 high?
The normal BUN level is between about 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, it may not help your healthcare provider measure your kidney health. A better measure is the ratio of BUN to creatinine found in your blood.
Why is Bun rising higher than normal level?
Higher than normal BUN levels can also be caused by dehydration, burns, certain medicines, a high protein diet, or other factors, including your age. BUN levels normally increase as you get older.
What is considered dangerous high bun level?
High BUN levels may also be the consequence of a lack of blood flow to the kidneys, due to heart failure. Taken together, high levels of BUN and creatine are often an indicator of kidney disease. The blood urea nitrogen to creatinine ratio has been devised to measure this relationship and arrive at a diagnosis.
How to decrease high BUN levels?
Eat a low-protein diet. If your kidneys are unable to filter protein properly, reduce your protein intake to lower your BUN levels. High-protein foods include red meat, poultry, fish and dairy. Beans, nuts and grains have moderate amounts of protein, and fruits generally have no protein.
How can you lower high bun level?
Drink water and other fluids to stay hydrated. Dehydration is one of the most probable causes of high BUN levels,but also the most preventable.
