What is the reason for urea nitrogen 13.9

13.9 millimoles per liter of urea nitrogen may indicate abnormal kidney function or be caused by factors such as a high protein diet. Elevated urea nitrogen is usually associated with decreased glomerular filtration rate, high protein diet, gastrointestinal bleeding, dehydration, medication effects, and other factors.

1. Decreased glomerular filtration rate

When renal function declines, the kidneys are unable to effectively filter urea nitrogen from the blood, leading to an increase in its level. May be accompanied by symptoms such as decreased urine output and edema. Further evaluation of renal function should be conducted through tests such as blood creatinine and urine routine. If necessary, medication such as Uremic Clearance Granules and Kidney Failure Ning Tablets should be used as adjunctive therapy according to medical advice.

2. High protein diet

Consuming large amounts of high protein foods such as meat and eggs in the short term can increase urea nitrogen production. This situation usually has no other abnormal symptoms, and the values can gradually return to normal after adjusting the diet structure. It is recommended to control the daily protein intake at 1-1.2 grams per kilogram of body weight.

3. Gastrointestinal bleeding

Blood breakdown in the intestine produces a large amount of nitrogen-containing substances, which are metabolized by the liver to form urea nitrogen. May be accompanied by symptoms such as black stool and vomiting blood. Complete examinations such as fecal occult blood and gastroscopy are required. After diagnosis, medication such as omeprazole enteric coated capsules and Yunnan Baiyao capsules can be used according to medical advice.

4. Dehydration

Loss of body fluids leads to blood concentration, which can cause a relative increase in urea nitrogen. Commonly seen in conditions such as diarrhea, high fever, or insufficient water intake, it may be accompanied by thirst and darkened urine color. Timely supplementation of electrolyte solution can improve, but severe dehydration requires intravenous fluid replacement treatment.

5. Drug effects

Corticosteroids, tetracycline antibiotics, and other drugs may interfere with protein metabolism or damage kidney function. If abnormal values are found after medication, doctors should be consulted to adjust the medication plan and avoid long-term use of nephrotoxic drugs such as gentamicin injection.

It was found that the increase in urea nitrogen needs to be comprehensively judged in combination with other indicators. It is recommended to re-examine renal function and improve urine routine, renal ultrasound and other examinations. Daily attention should be paid to controlling protein intake, drinking 1500-2000 milliliters of water per day, and avoiding dehydration after intense exercise. If accompanied with edema, fatigue and other symptoms, timely medical treatment should be carried out in the nephrology department, and diabetes patients need to synchronously monitor the blood sugar level.
