Prevalence, Awareness and Correlates of Self-Reported Hypoglycemia Among Adults with Type 2 Diabetes in Northern Jordan: A Cross-Sectional Study
This cross-sectional study of 326 adults with type 2 diabetes in northern Jordan reveals a high prevalence of self-reported hypoglycemia (79.1%) linked to insulin and sulfonylurea use, while highlighting significant gaps in patient awareness, reporting to healthcare providers, and emergency preparedness.

Diabetes is a condition where the body struggles to manage the sugar in the blood, a fuel that powers every cell. To keep this fuel at a safe level, many people take medicine that lowers it. However, these treatments can sometimes work too well, dropping the sugar level so low that the body cannot function properly. This state is called hypoglycemia. It can cause shaking, confusion, or dizziness, and if it happens without warning, it can be dangerous. While doctors know this risk exists, they often do not know how often it happens in everyday life, especially in specific regions where people might have different habits, diets, or access to care. Understanding the true frequency of these low-sugar events and why patients might not tell their doctors about them is crucial for keeping people safe.
In northern Jordan, researchers set out to uncover the reality of these low-sugar episodes among adults with type 2 diabetes. They visited two different medical centers: a large teaching hospital and a smaller primary care clinic. Over the course of a year, they spoke directly with 326 adults who were managing their diabetes. The team asked detailed questions about their health, their medications, and their daily lives, while also checking their medical records to confirm lab results. They defined a low-sugar event as either a blood test showing a level below 70 mg/dL or a person feeling symptoms that went away after eating something fast-acting like candy or juice.
The results revealed a startlingly common problem. Nearly four out of every five patients, or 79.1 percent, reported having experienced at least one of these low-sugar episodes in the six months before the study. This number is significantly higher than what has been seen in many other studies. The researchers found that the risk was not spread evenly. Patients who took insulin were much more likely to have these episodes than those who did not. Similarly, those taking a specific class of pills called sulfonylureas faced higher odds. Interestingly, the place where a patient received their care mattered greatly. People visiting the primary care clinic were nearly three times more likely to report an episode than those at the large hospital, even after accounting for the types of medicines they took. This suggests that the environment of primary care, perhaps due to different patient mixes or how care is delivered, plays a significant role in who experiences these drops in blood sugar.
Beyond the numbers, the study uncovered a worrying gap in knowledge and communication. While most patients could name the symptoms of low blood sugar, the vast majority did not know that these episodes could happen without any warning signs at all. This lack of awareness is dangerous because it leaves patients unprepared. Furthermore, more than half of the patients who had these episodes never told their doctors about them. The most common reason given was that they did not think the episode was serious enough to mention. Many also admitted they did not carry sugar or an emergency kit with them, leaving them vulnerable if an episode occurred while they were away from home.
The researchers also looked at other factors that might influence these events. They found that having kidney disease, a common complication of diabetes, was linked to a higher risk of low blood sugar. Surprisingly, patients who took beta-blockers, a type of medicine often used for heart conditions, were less likely to report these episodes. The authors caution that this might not mean the heart medicine prevents low sugar, but rather that it could hide the warning signs, making patients less likely to notice or report the event. They also found that skipping meals was a strong predictor of low sugar, which makes sense given that food is the body's main source of fuel.
This study paints a clear picture of a hidden burden in diabetes care. The high rate of low-sugar episodes, combined with the fact that many patients do not recognize the danger of silent episodes or feel comfortable reporting them, suggests that current care routines are missing critical opportunities to protect patients. The findings point to a need for doctors to ask more specific questions about low blood sugar at every visit, to educate patients about the possibility of silent episodes, and to carefully review medications for those at highest risk, particularly in primary care settings. By addressing these gaps, healthcare providers can help ensure that the treatment for diabetes does not inadvertently create new dangers for the people it is meant to help.
