The present disclosure discloses a system and a method for determining an injectable amount of bile required for a patient after gallbladder removal. The system comprises a receiving module, a creating module, and a determining module. The receiving module may receive a bile-flow rate, physiological parameters of a patient, and amount of fatty food in an alimentary tract of the patient. Based on these data received, the creating module may create a graph. Further, the determining module may determine a correlation between the bile-flow rate and the amount of fatty food in the alimentary tract based on the graph created. The correlation may be determined corresponding to a normal person and the patient which may be seen by two separate curves on the graph. Further, the determining module may determine an injectable amount of bile required for the patient based on the correlation.
