Hypoglycaemia

hypoglycaemia (low blood sugar) occurs when blood glucose levels fall below normal, typically below 3.9 mmol/L (70 mg/dL)... while it is most commonly associated with people who have diabetes and are taking insulin or certain glucose-lowering medications, it can also occur in individuals without diabetes under specific circumstances... it can develop rapidly and, if left untreated, may progress from mild symptoms to a life-threatening medical emergency... because the brain relies heavily on glucose as its primary source of energy, a significant drop in blood sugar can impair both physical and mental function within a short period of time...

early warning signs often include sudden hunger, sweating, shakiness, trembling, dizziness, weakness, palpitations, anxiety, irritability, headache, and difficulty concentrating... many people describe feeling not quite right or experiencing a sudden lack of energy... as blood sugar continues to fall, the symptoms may become more severe, including confusion, blurred vision, slurred speech, poor coordination, unusual behaviour, personality changes, or extreme drowsiness... in severe cases, a person may lose consciousness, experience seizures, or become unable to swallow safely, requiring immediate emergency medical treatment...

several factors can trigger it... these include skipping meals, delaying meals, excessive physical activity without adequate food intake, taking too much insulin or diabetes medication, consuming alcohol on an empty stomach, or prolonged fasting... individuals who are elderly, have kidney disease, or have long-standing diabetes may be at greater risk because their body's ability to recognize and respond to low blood sugar can be impaired...

prompt treatment is essential... for a conscious person, the recommended approach is to consume a fast-acting source of glucose, such as glucose tablets, fruit juice, regular soft drinks (not sugar-free), honey, or sweets... once blood sugar begins to recover, a more substantial snack or meal should be eaten to prevent recurrence... however, if the individual becomes unconscious, has a seizure, or cannot swallow safely, emergency medical assistance should be sought immediately... food or drinks should never be forced into the mouth of an unconscious person due to the risk of choking...

the most important message is that it should never be underestimated... what starts as mild sweating or shakiness can quickly progress to confusion, loss of consciousness, and serious complications if not treated promptly... recognizing the early warning signs, acting quickly, and maintaining regular meals and medication schedules are essential steps in preventing it from becoming a medical emergency... for people living with diabetes, carrying a source of fast-acting glucose at all times can be a simple yet potentially lifesaving habit...
