Creatinine, a byproduct of muscle metabolism, is crucial for assessing kidney function as its elevated levels can indicate kidney disorders, dehydration, muscle damage, or the effect of certain medications. It can also increase due to excessive intake of red meat.
Low creatinine levels, often associated with low muscle mass or debilitation, can indicate conditions like muscular dystrophy and myasthenia gravis.
Importantly, persistently low creatinine levels are linked with an increased risk of type 2 diabetes, possibly due to its connection with skeletal muscle, a primary target of insulin.
Thus, creatinine levels, whether high or low, can provide significant insights into a person's health status.
