Common reasons for low Albumin:

  • Low albumin is primarily a consequence of illness rather than a cause, and it serves as a late-stage indicator of inflammation. It is frequently observed in chronic or persistent inflammatory states.

    Low albumin is also associated with liver disease, kidney disease, diabetes, heart failure, fluid overload, advanced malnutrition (particularly from protein deficiency or malabsorption), severe burns, and occasionally cancer.
