What are the causes and hazards of low creatinine

Low creatinine levels may be caused by factors such as decreased muscle mass, malnutrition, long-term bed rest, physiological changes during pregnancy, or liver disease. In most cases, it is a physiological change, but persistent low levels require caution about potential health risks.

1. Decreased muscle mass:

Creatinine is a product of muscle metabolism, and insufficient muscle mass can lead to reduced production. This condition is common among elderly people, long-term food eaters, or patients with muscle atrophy, and can be improved through moderate strength training and protein supplementation. 2. Malnutrition: Insufficient protein intake can affect creatinine synthesis. Long term vegetarians and patients with digestive and absorption disorders may experience this phenomenon and need to adjust their diet structure to increase the intake of high-quality protein such as lean meat and eggs.

3. Long term bed rest:

Reduced muscle activity can lower creatinine production. Postoperative patients and paralyzed individuals need to undergo regular monitoring of indicators and receive rehabilitation training under the guidance of a doctor to maintain muscle function.

4. Changes during pregnancy:

Increased blood volume in pregnant women can lead to a dilutive decrease in creatinine, which is a normal physiological phenomenon. But it needs to be distinguished from pregnancy complicated liver disease, and regular prenatal check ups should be conducted to monitor changes in liver function.

5. Liver disease:

Severe liver disease can affect the synthesis of creatinine precursor substances. Cirrhotic patients may experience symptoms such as decreased creatinine, jaundice, and ascites, and require timely liver function tests and ultrasound diagnosis.

It is necessary to maintain a balanced diet in daily life, with a daily intake of 1.2-1.5 grams/kg of high-quality protein. Priority should be given to easily absorbable protein sources such as fish and soy products. Conducting resistance training 3-5 times a week for 20-30 minutes each time can effectively maintain muscle mass. When the long-term creatinine level is below 50% of the normal range, or accompanied by symptoms such as fatigue and edema, it is recommended to complete thyroid function, liver function, and other examinations to exclude pathological factors. During the monitoring period, daily diet and exercise should be recorded to provide reference for doctors' diagnosis.
