The tissue status measuring apparatus includes an electrode set and a control module coupled to the electrode set. The electrode set is configured to emit a first sensing electric field toward a dielectric area and to form a capacitive loop with the dielectric area. The control module includes a driving unit and a processing unit. The driving unit is configured to output a driving signal to the electrode set to output the first sensing electric field. The processing unit is configured to measure a loop capacitance value of the capacitive loop. In response to a tissue under test being located within the dielectric area, the loop capacitance value of the capacitive loop is a first measured capacitance value. In response to a difference between the first measured capacitance value and a baseline capacitance value being greater than an abnormality threshold, the processing unit determines that the tissue under test has an abnormal tissue location.
