This research aims to examine existing research on the relationship among (T2DM) type 2 diabetes mellitus and asthma in adulthood, the processes underlying this relationship, and the effects of T2DM on asthma management. It has been hypothesized that moderate levels of systemic inflammation or the application of antibiotics are to blame for the link between T2DM and asthma. It is noted that till now, there has been little scholarly research on the effects of this link on asthma management. The epidemiological statistics and routine healthcare procedures show that people with asthma also frequently have different kinds of diabetes mellitus (DM). The debate over the effects of an inflammatory disorder associated with asthma on glucose metabolism and the prevalence of persistent hyperglycemia and signs of inflammation in asthma patients remains debatable. It has been demonstrated that dysfunctional immune systems and genetic predisposition are related to asthma and type 1 diabetes mellitus (T1DM) and that obesity and insulin resistance (IR) plays a crucial role in promoting an excessively inflammatory nature and immune system reactions in type 2 diabetes mellitus. According to the findings, DM and asthma either impact one another's clinical manifestations, prognosis factors, and treatment options. Regardless of the probable involvement of metformin and the hyperglycemic adverse reactions to glucocorticoids, there is continuing debate regarding the efficacy and safety of anti-asthma and hypoglycemic treatment in this population of participants. Conclusion: Asthma and type 2 diabetes (T2DM) are two prevalent chronic diseases with a rising incidence that frequently interact in the same individual. It has been hypothesized that this cohabitation makes asthma management more severe. Since T2DM is a comorbidity linked with asthma, the research could promote legislative initiatives and therapeutic medical procedures that value this strategy with the objective to decrease the standard of life and other dangers to health. Consequently, the goal of the article being given is to examine what is known about the correlation between DM and asthma, their likely relationships with each other, and treatment possibilities.
