What is the reason for high urea levels during physical examination

Elevated blood urea levels during physical examination may be related to factors such as insufficient water intake, high protein diet, abnormal kidney function, urinary tract obstruction, heart failure, etc. It can be improved by adjusting diet, increasing water intake, medication treatment, relieving obstruction, and controlling the underlying disease.

1. Insufficient water intake

Prolonged lack of water intake can lead to urine concentration and a relative increase in blood urea concentration. This condition usually has no other discomfort symptoms. Increasing the daily water intake to at least 2000 milliliters and keeping the urine light yellow can alleviate it. Avoid not replenishing water in a timely manner after intense exercise or staying in a high-temperature and dry environment for a long time.

2. High protein diet

Consuming large amounts of high protein foods such as meat and eggs in the short term can increase urea production. Eating protein rich foods such as barbecue and seafood within 48 hours before the physical examination may cause temporary elevation of indicators. It is recommended to maintain a daily protein intake of 1-1.2 grams per kilogram of body weight, and prioritize high-quality protein sources such as fish and soy products.

3. Abnormal renal function

Chronic nephritis, diabetes nephropathy and other diseases will lead to a decrease in glomerular filtration rate and urea excretion. May be accompanied by symptoms such as increased nocturia and lower limb swelling. Follow the doctor's advice to use Bailing capsules to protect kidney function, or take Uremic Clearance Granules to assist in the elimination of metabolic waste. In severe cases, blood purification treatment is necessary.

4. Urinary tract obstruction

Urinary tract obstruction caused by diseases such as kidney stones and prostate hyperplasia can cause urea to remain in the body. Often accompanied by symptoms such as difficulty urinating and cramping in the waist and abdomen. After diagnosis through ultrasound examination, the patient can take sustained-release capsules of tamsulosin hydrochloride to relax smooth muscles, or use extracorporeal shock wave lithotripsy to relieve obstruction.

5. Heart failure

Inadequate renal perfusion during cardiac insufficiency will lead to urea nitrogen retention. There are often symptoms such as chest tightness, shortness of breath, and lower limb edema. It is necessary to standardize the use of furosemide tablets for diuresis and reducing cardiac load, while controlling underlying diseases such as blood pressure and blood sugar. Patients with severe heart failure should consider implanting a pacemaker to improve circulatory function.

If high urea levels are found, renal function indicators should be rechecked to avoid testing immediately after intense exercise. Maintain a low salt and high-quality protein diet in daily life, with a daily intake of no more than 5 grams of salt. Prioritize easily digestible proteins such as chicken breast and tofu. Moderate aerobic exercise such as brisk walking and swimming can promote metabolism, but avoid overloading exercises such as marathons. If accompanied by symptoms such as persistent fatigue and changes in urine output, timely medical attention should be sought from the nephrology department.
