Low blood sugar, or hypoglycaemia, poses significant risks, particularly to the brain, which relies almost exclusively on glucose for energy. Dr. Sreelakshmi N., a neurologist at S.L. Raheja Hospital in India, warns that when glucose levels drop sharply, it can lead to disorganized electrical activity in the brain, resulting in seizures or loss of consciousness. Symptoms of hypoglycaemia can begin subtly, with confusion and irritability, and can escalate to severe manifestations such as convulsions. Dr. Shailaja Kale, a diabetes consultant at Sahyadri Hospital, highlights that severe hypoglycaemia often arises from medication imbalances, such as incorrect insulin dosages, and lifestyle factors like skipping meals or excessive exercise. Early warning signs include sweating, trembling, and dizziness. Immediate consumption of fast-acting sugar can avert serious complications. Preventative measures include maintaining stable glucose levels through consistent meal timing, proper medication use, and regular monitoring. High-risk individuals should be educated on recognizing symptoms and keeping glucose sources readily available. By fostering awareness and preparedness, the risks associated with hypoglycaemia can be effectively managed.
