Low blood creatinine is not clinically significant and does not usually lead to increased nocturia.
Increased nocturia generally refers to an increase in the frequency of urination at night or an increase in the volume of urine at night.
Increased nocturia may be caused by drinking too much water during the day, drinking strong tea or coffee before going to bed, or by mental stress. In pathological cases, it may be due to decreased reabsorption capacity of renal tubules caused by renal disease leading to increased nocturia. In addition, cardiac insufficiency or chronic adrenocortical insufficiency may also be combined with increased nocturia.
Creatinine is a metabolite in the body, usually produced by muscle and excreted by the kidneys.
A low blood creatinine value may be due to a decrease in muscle content, which generally does not lead to increased nocturia; a high blood creatinine value may be due to impaired renal function, leading to a decrease in blood creatinine output, which may be combined with an increase in nocturia if the renal function is severely impaired.
If the increase in nocturia is not caused by increased water intake, and the symptoms continue to be unrelieved, it is recommended to go to a regular hospital in a timely manner, and follow the doctor’s instructions for standardized treatment.
