What is a high cardiac index? low cardiac index.
The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1. Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.
The ratio is useful for the diagnosis of bleeding from the gastrointestinal (GI) tract in patients who do not present with overt vomiting of blood. In children, a BUN:Cr ratio of 30 or greater has a sensitivity of 68.8% and a specificity of 98% for upper gastrointestinal bleeding.
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.
Blood Tests A creatinine level of greater than 1.2 for women and greater than 1.4 for men may be an early sign that the kidneys are not working properly. As kidney disease progresses, the level of creatinine in the blood rises.
The BUN/creatinine ratio is a good measurement of kidney and liver function. The normal adult range is 6 to 25, with 15.5 being the optimal value.

Please Note: If results for BUN and Creatinine are both within the normal reference range, the BUN/Creatinine ratio will not be reported (not applicable). Clinical Significance: The BUN/Creatinine ratio is useful in the differential diagnosis of acute or chronic renal disease.
A blood urea nitrogen (BUN) level of 75 mg/dL is a useful indicator for dialysis in asymptomatic patients, but one that is based on studies with limitations. Different parameters, including absolute and relative indicators, are needed.

What are considered high creatinine levels? A person with only one kidney may have a normal level of about 1.8 or 1.9. Creatinine levels that reach 2.0 or more in babies and 5.0 or more in adults may indicate severe kidney impairment.
If you’re worried about creatinine levels, avoid high-protein foods, like: Red meat. Dairy products. Eggs.
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.
Drinking more water could lower the serum creatinine level, but does not change kidney function. Forcing excessive water intake is not a good idea.
Vitamin D receptor activation has been associated with increased serum creatinine and reduced estimated glomerular filtration rates, raising concerns that its use may be detrimental to kidney function.
- amphotericin B (AmBisome, Fungizone)
- carbamazepine (Tegretol)
- cephalosporins, a group of antibiotics.
- furosemide (Lasix)
- rifampin (Rifadin)
- spironolactone (Aldactone)
Generally, a high BUN level means your kidneys aren’t working well. But elevated BUN can also be due to: Dehydration, resulting from not drinking enough fluids or for other reasons. Urinary tract obstruction.
- High blood pressure.
- Swelling in legs.
- Urinary tract infections.
- Abnormal urine test (protein in urine)
Sodas. According to the American Kidney Fund, a recent study suggests that drinking two or more carbonated sodas, diet or regular, each day may increase your risk for chronic kidney disease. Carbonated and energy drinks have both been linked to the formation of kidney stones.
It can come and go or it may be continuous. It may affect your whole body or be limited to a specific area – usually your back or arms. Itching tends to affects both sides of the body at the same time and may feel internal, like a crawling feeling just below the skin.
National Kidney Foundation guidelines recommend you start dialysis when your kidney function drops to 15% or less — or if you have severe symptoms caused by your kidney disease, such as: shortness of breath, fatigue, muscle cramps, nausea or vomiting.
Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
Here are the normal values by age: 0.9 to 1.3 mg/dL for adult males. 0.6 to 1.1 mg/dL for adult females. 0.5 to 1.0 mg/dL for children ages 3 to 18 years.
In summary, coffee is an acceptable beverage for kidney disease. If consumed in moderation it poses little risk for those with kidney disease. Additives to coffee such as milk and many creamers increase the potassium and phosphorus content of coffee.
Following treatment of the underlying cause, creatinine levels should return to normal. Creatinine is a waste product of the muscles. In a healthy body, the kidneys filter creatinine from the blood and excrete it through the urine. High levels of creatinine can indicate kidney issues.
Peanut butter is a high potassium, high phosphorus ingredient but still works in a kidney diet as a substitute for meat. Portion control is important. Additional phosphate binder may be required if eaten as a snack—check with your renal dietitian.
Consuming lemon water can have minimal effect in reducing the creatinine levels, but it won’t contribute to its growth. Creatinine is a waste chemical product, which is a by-product of the wear and tear of our muscles. The more muscles a person has, the more creatinine will be present in the blood.
Grapes, apples, and cranberries, as well as their respective juices, are all good substitutes for oranges and orange juice, as they have lower potassium contents. Oranges and orange juice are high in potassium and should be limited on a renal diet. Try grapes, apples, cranberries, or their juices instead.
