An illustrative hearing system may include an optical waveguide at least partially positioned within an ear canal of a user and having a sensing region located between a first end and a second end of the optical waveguide. A light source may be configured to emit light into the optical waveguide at the first end, such that a first portion of the light may exit the optical waveguide at the sensing region and be absorbed by cerumen within the ear canal. A detector may be configured to detect a second portion of the light that exits the optical waveguide at the second end. A processing unit may be configured to determine, based on the second portion of the light detected by the detector and the light emitted by the light source, a glucose value representative of a glucose concentration in the cerumen.
