There are at least 60 approved medicines. Moreover, obese diabetes itself is multifactorial and complex, which in many cases leads to other health complications (e.g., cardiac diseases, stroke, liver and kidney diseases, cancers, etc.) and requires combined drugs treatment. This is thus significantly challenging for doctors to evaluate the patients’ condition and effectively provide multiple drugs prescription.

Additionally, according to clinical reports, many of the prescribed drugs do not work as expected and need to be re-defined for each patient’s needs. The drug-to-drug interaction has not been systematically recorded and deeply studied, posing high risks of disease complications. Precision treatment is thus urgently needed.
