Fear of hypoglycemia has a significant impact on both medication and dietary adherence in individuals with diabetes. Through avoidance behaviors, it can disrupt metabolic control, prevent the achievement of glycemic targets, and increase the risk of long-term complications. Therefore, monitoring only biochemical parameters is insufficient in diabetes management. It is crucial for healthcare professionals to systematically assess the fear of hypoglycemia.

Fear of hypoglycemia can directly affect individuals' adherence to treatment, dietary habits, and self-management behaviors. Low levels of fear can lead to ignoring the risk of hypoglycemia, downplaying symptoms, and creating a predisposition to subsequent hypoglycemic attacks, increasing the risk of life-threatening complications. On the other hand, excessively high levels of fear can create constant anxiety, emotional stress, discomfort, and feelings of insecurity, reducing quality of life and triggering depressive symptoms. Furthermore, individuals with high levels of fear tend to maintain higher glucose levels to avoid hypoglycemia. This leads to impaired metabolic control and an increased risk of long-term complications. Additionally, fear of hypoglycemia can significantly affect how individuals regulate their insulin doses, physical activity, and food intake.The literature indicates that fear of hypoglycemia triggers avoidance behaviors in individuals with diabetes, which often leads to poor treatment adherence. These avoidance behaviors include strategies such as consciously reducing insulin doses, skipping oral antidiabetic medications, or not adhering to the treatment plan. This makes it difficult to reach target glycemic levels, increasing the risk of complications in the long term. Fear of hypoglycemia can negatively affect not only medication adherence but also dietary and nutritional behaviors. It is common for individuals who want to avoid hypoglycemia to consume more carbohydrates than planned meals, add excessive snacks to protect against nocturnal hypoglycemia, or develop irregular eating habits. These behaviors can lead to impaired glycemic control, weight gain, and hyperglycemia, hindering the achievement of metabolic goals. This study aims to address an important gap in diabetes management by examining the impact of fear of hypoglycemia on dietary and medication adherence in patients with diabetes. Fear of hypoglycemia may lead patients to consciously or unconsciously reduce medication doses, skip meals, or deviate from recommended dietary plans. Such behaviors can result in poor glycemic control and increase the risk of diabetes-related complications in the long term. The findings of this study are expected to help healthcare professionals identify fear of hypoglycemia at an early stage and develop individualized education, counseling, and care plans. Consequently, improving treatment adherence and enhancing the quality of life of patients with diabetes may be achieved.
