As I am first to respond your question ...
Blood Urea Nitrogen (BUN) is another measure of wastes (urea) in the blood. Urea is produced from the breakdown of protein already in the body and protein in your diet. A high BUN usually means that kidney function is less than normal, but other factors may affect the BUN level. Bleeding in the intestines, congestive heart failure, and certain medications may make the BUN higher than normal. As BUN rises, symptoms of kidney disease may appear, such as a bad taste in the mouth, poor appetite, nausea, and vomiting.
The normal BUN level for healthy individuals is 7-20 mg/dL in adults, and 5-18 mg/dL in children.
You have value of 40 , so you should once consult Nephrologist please .
