Technologies for managing device functions of an ingestible computing device include determining whether adaptation of a device function of the ingestible computing device is required based on sensor data generated by the ingestible computing device. If device function adaption is determined to be required, the ingestible computing device determines a new device function to be performed, obtains program code modules to perform the new device function, and locally compiles the new program code modules to generate executable code. The ingestible computing device may execute the executable code to cause the ingestible computing device to begin performing the new device function. The ingestible computing device may obtain the program code modules from a local function database or via an authenticated wireless communication.
