Rising risk of hypoglycaemia unawareness highlights urgent need for diabetes monitoring

People with diabetes face increasing danger from hypoglycaemia unawareness, a condition where warning signs diminish, raising the risk of severe complications. Experts emphasise the importance of regular testing to prevent emergencies and long-term health issues.

People with diabetes may sometimes experience a dangerous drop in blood glucose without the usual warning signs, a condition known as hypoglycaemia unawareness. The risk is highest for people using insulin and for those who have repeated low-sugar episodes, because the body can gradually stop sending the alarms that normally prompt someone to eat or drink something fast. The Centers for Disease Control and Prevention says blood sugar below 70 mg/dL is low and needs prompt treatment to avoid serious complications.

Under normal circumstances, the body reacts to falling glucose with symptoms such as shaking, sweating, hunger, a racing heartbeat, dizziness and anxiety. These signals are meant to act as an early warning system, giving the person time to take in quick carbohydrates before levels fall further. But when low blood sugar happens often, that warning system can become blunted, making future episodes harder to detect and more dangerous.

According to the CDC and the Mayo Clinic, severe hypoglycaemia can progress to confusion, trouble speaking or moving normally, seizures and loss of consciousness. In the most serious cases, it can lead to coma. The Mayo Clinic notes that low blood sugar can be triggered by too much insulin or other diabetes medicine, missed meals, eating too little, more exercise than usual without adjusting food intake or medication, and alcohol use. Some medical conditions, including severe liver or kidney disease, can also contribute.

The broader challenge is that diabetes itself can develop quietly. The CDC says symptoms of diabetes may include frequent urination, increased thirst and hunger, fatigue, blurred vision, irritability, unexplained weight loss and recurring infections, although some people have few or no symptoms at first. That is one reason regular testing and monitoring matter so much: catching abnormal blood sugar early can help prevent both immediate emergencies such as hypoglycaemia and longer-term complications, including diabetic ketoacidosis, a separate and potentially life-threatening condition linked to insufficient insulin.
