Hello, a low serum creatinine level may be associated with malnutrition, a vegetarian diet, low muscle mass, or reduced physical activity. Individuals who are particularly slender or petite often have lower creatinine levels. Pregnant women also commonly exhibit decreased creatinine levels. Additionally, some patients may experience reduced serum creatinine following severe illness or trauma. Creatinine is a byproduct of muscle metabolism; therefore, higher muscle mass generally correlates with higher serum creatinine levels, whereas lower muscle mass tends to result in lower creatinine levels. Consequently, female patients—who often engage in less physical activity, have a leaner body habitus, and possess relatively lower muscle mass—are especially prone to low serum creatinine levels. We hope this information is helpful to you. Wishing you a happy and healthy life!
