A method and system for relieving high blood sugar factor of diabetes, which comprises an energy wave generator having an energy wave's frequency control mode. The energy wave's frequency control mode includes multiple controls in multiple energy wave generation periods respectively, the multiple controls acting the energy wave generator to emit energy waves with corresponding specific energy densities within values of 0.99-7.25 by corresponding specific base frequencies between 1~18150Hz to effect on the body of diabetes to reduce or eliminate a high blood sugar factor of diabetes.
