The purpose of this study was to evaluate the health outcomes of diabetic patients in Puerto Rico, before, during, and after Hurricane Maria, in 2017. The Department of Health in Puerto Rico provided the secondary data for the variables low-density lipoproteins (LDL) cholesterol, hemoglobin A1C (HbA1c), mortality, and consumer price index (CPI). The inclusion criteria were participants for whom electronic data were available before, during, and after Hurricane Maria; the sample size was 450. The theoretical framework for this investigation was the health outcomes and impact assessment. The data were analyzed by univariate and analysis of variance (ANOVA) to compare means and normality test analysis. Results of this study revealed that before Hurricane Maria, diabetics in Puerto Rico did not have control of their health. The American Diabetes Association (ADA) guideline for Hgb AIC is < 7.0; prior to Hurricane Maria Hgb AIC was 7.30 and after it was 7.21. The ADA LDL goal is
