Why is higher urinary creatinine better?

Generally speaking, there is no such thing as higher urine creatinine being better. Elevated urine creatinine levels may be related to intense physical exercise, high-protein diet, hypothyroidism, polymyositis, chronic kidney disease, and other causes. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Intense Physical Exercise

After intense physical activity, the body's metabolic rate increases and muscle breakdown rises, leading to increased production of creatinine. In such cases, elevated urine creatinine is temporary and represents a physiological response. Adequate rest should be taken and overexertion avoided.

2. High-Protein Diet

Consuming excessive meat or other high-protein foods increases protein metabolism, which can elevate blood creatinine levels and subsequently lead to higher urine creatinine. It is advisable to adjust dietary habits by reducing intake of high-protein foods and maintaining a balanced diet to avoid placing extra strain on the kidneys.

3. Hypothyroidism

Hypothyroidism may result from conditions such as thyroiditis, iodine deficiency, or excessive iodine intake. In this condition, insufficient thyroid hormone secretion slows muscle metabolism, but creatinine excretion may also be affected, resulting in elevated urine creatinine levels. Symptoms often include weight gain, constipation, and dry skin. Treatment typically follows medical advice and may include medications such as levothyroxine sodium tablets, thyroid tablets, or hydrocortisone injection.

4. Polymyositis

Polymyositis may be triggered by infections, autoimmune factors, and other causes. When muscle tissue is inflamed or damaged, large amounts of creatine kinase and creatinine are released into the bloodstream, exceeding the kidneys' excretory capacity and leading to increased urinary creatinine concentration. Common symptoms include muscle weakness, pain, and tenderness. Treatment under medical supervision may include azathioprine tablets, prednisone acetate tablets, or methotrexate injection.

5. Chronic Kidney Disease

Chronic kidney disease may be caused by factors such as hypertension or kidney stones. As kidney filtration function gradually declines in chronic kidney disease, serum creatinine levels rise. To maintain creatinine balance, remaining functional kidney units may compensate by increasing their filtration rate, resulting in elevated urine creatinine concentration. Common symptoms may include proteinuria, edema, and anemia. Treatment should follow medical guidance and may involve medications such as fosinopril sodium capsules, telmisartan capsules, or huangkui capsules.

In daily life, it is important to maintain a well-balanced diet emphasizing high-quality protein, sufficient caloric intake, and adherence to low-salt, low-potassium dietary principles to avoid加重 bodily burden.
