Multiple experimental and clinical studies have suggested that in addition to generating a pulmonary clinical presentation, it can also cause lesions in differ ent systems. The present study seeks to associate that SARS-CoV-2 infection can generate a hyperglycemicstate in patients without a previous diagnosis of Diabetes Mellitus, as well as to find the prev alence of this complication in specific groups of the population. Overall Objective: To determine the prevalence of hyperglyc emia in the subjects who studied COVID-19 of the Family Medicine unit No 32. Material and methods: An observational, descriptive, cross sectional and retrospective study was developed with a non probabilistic sampling of consecutive cases in the population of patients with COVID-19 of the Family Medicine Unit No. 32 of the Mexican Institute of Social Security with an age range of 18 - 65 years. Obtaining a sample of 152 participants who met the inclu sion criteria. Results: A prevalence of 30.26% was found in the participants who presented post-COVID hyperglycemic figures. Conclusion: In the present study we can conclude that there was an alteration in post-COVID serum glucose levels without the use of steroids, which is why future follow-up is suggested for pa tients who suffered from COVID-19 to monitor the possible onset of pre-diabetes or diabetes.
