What Does a Low Creatinine Level Mean?

Start Reading

Creatinine is frequently measured in milligrams per deciliter of blood (mg/dL). The test results could vary based on age and gender.

Normal Range

Normal creatinine levels for adult men range from 0.7 to 1.3 mg/dL, while normal levels for adult women range from 0.5 to 1.1 mg/dL.

Low and high creatinine have different causes. Low creatinine levels can cause decreased mobility, jaundice, and water loss. But, what lowers creatinine?

Causes: Low Muscle Mass

Medical News Today says those with low muscle mass have lower creatinine levels. Muscle deterioration is a natural part of aging and not a serious medical concern.

Causes: Diet

Diet can lower creatinine levels in addition to aging. Since creatinine is mostly found in meat, vegetarians and those on a low-protein diet have low levels.

Causes: Disease

Some people with liver disease, poor liver function, or muscular dystrophy may have low creatinine levels.

Causes: Pregnancy

A 2022 Scientific Reports study linked low creatinine levels to pregnancy. Pregnancy lowers creatinine levels.


Healthline says that the best way to treat low creatinine levels depends on what's causing them. If low muscle mass is the cause, there is no need to see a doctor.

But your doctor might suggest that you make changes to your lifestyle and diet to build muscle mass and bring your creatinine levels back to normal.
