Introduction
Hypovolemia, inappropriate medication use, obstruction, and other factors may lead to renal failure, resulting in relatively enhanced renal clearance of urea, thereby causing decreased blood urea concentration, accompanied by symptoms such as hypertension and increased nocturnal urination. It is recommended to use medications such as benazepril hydrochloride tablets, compound ferrous sulfate granules, and ferrous succinate granules under medical guidance for treatment.

Under normal circumstances, decreased urea concentration may be caused by excessive water intake, intense physical exercise, liver dysfunction, hepatitis, or renal failure. If discomfort occurs, it is recommended to seek medical attention promptly for targeted treatment. Specific causes are analyzed as follows:

1. Excessive water intake

Drinking large amounts of water or receiving excessive intravenous fluids can lead to blood dilution, resulting in a relatively lower concentration of urea in the bloodstream. This condition typically does not present specific accompanying symptoms, and it is advisable to moderately control fluid intake.

2. Intense physical exercise

After intense exercise, increased protein breakdown in muscle tissue may occur, but the liver's conversion of ammonia into urea may not keep pace, leading to a temporary decrease in urea concentration. This is usually asymptomatic. It is recommended to rest appropriately and ensure adequate hydration and nutritional replenishment to avoid excessive fatigue.

3. Liver dysfunction

Impaired liver function may lead to reduced kidney function, preventing the liver from effectively converting ammonia into urea, thus causing decreased urea levels. Symptoms often include ascites and loss of appetite. It is recommended to take medications such as Liganzhipian, Yigan Fuzheng Capsules, or Shugan Pills under medical supervision.

4. Hepatitis

Viral infections may trigger hepatitis, and the inflammatory response can impair liver metabolism, reducing urea production from proteins in the liver and thereby lowering blood urea concentration. Common symptoms include nausea and vomiting. Treatment with medications such as Entecavir Dispersible Tablets, Phenobarbital Tablets, or Compound Glycyrrhizin Tablets should follow medical advice.

5. Renal failure

Renal failure may result from factors such as inadequate blood volume, inappropriate medication use, or urinary tract obstruction. This condition may enhance the kidneys' relative ability to clear urea, leading to decreased blood urea concentration, often accompanied by symptoms like hypertension and increased nocturnal urination. It is recommended to use medications such as Benazepril Hydrochloride Tablets, Compound Ferrous Sulfate Granules, or Ferrous Succinate Granules under medical guidance.

During treatment, consumption of spicy, raw, or cold foods should be avoided to prevent bodily discomfort.
