Hi,
Creatinine is a waste product produced by muscles that are filtered out of the body by the kidneys. Abnormal creatinine levels can indicate a problem with kidney function. Many factors can cause high creatinine levels, including:
* Kidney disease: This is the most common cause of high creatinine levels. Damage to the kidneys can lead to decreased filtration of creatinine, causing it to accumulate in the blood.
* Dehydration: When the body is dehydrated, the kidneys may not function properly, leading to higher creatinine levels.
* Muscle damage: Any condition that causes damage to the muscles can cause an increase in creatinine levels, as it is produced by muscles.
* Medications: Certain medications, such as antibiotics, can cause an increase in creatinine levels.
* High protein diet: Eating a diet high in protein can cause an increase in creatinine levels.
* Age and gender: Creatinine levels can be higher in older adults and men due to differences in muscle mass.
It is important to follow up with your doctor to determine the cause of your elevated creatinine levels and to monitor your kidney function. In some cases, lifestyle changes, medication adjustments, or further testing may be necessary.
