The Effects of Green Tea Infusion on Blood Sugar Levels of Employees with Hyperglycemia

Background: Blood sugar is one of the sources of energy in the body. Blood sugar levels are influenced by several factors such as age, gender, physical activity, stress, and diet. Increased blood sugar levels beyond normal limits are referred to as hyperglycemia. Hyperglycemia can cause symptoms such as frequent thirst, dizziness, blurry vision, and increased urination intensity. Green tea has an antihyperglycemic effect because it contains catechins, tannins, saponins, and alkaloids that can lower blood sugar levels. Objective: This study aims to determine the effect of consumption of infusion green tea on the blood sugar levels of employees with hyperglycemia. Method: The research design used a pseudo-experimental design with a type of non-randomized control group pretest posttest design. The sampling technique uses a purposive sampling nonprobability sampling method with a minimum sample of 18 respondents in each group. Data analysis using the Mann-Whitney analysis test and Wilcoxon Test. Results: After being given green tea from a total of 18 respondents in the case group, 5 people experienced a decrease in blood sugar levels, 3 people experienced an increase, and 10 people experienced no change. The results of the analysis test showed no effect of infusion green tea on the blood sugar levels of employees with hyperglycemia with the results of the Mann-Whitney test value p = 0.20 and Wilcoxon test value p = 0.53. Conclusions: There was no effect of infusion green tea on the blood sugar levels of employees with hyperglycemia.
