Low blood sugar episodes can be mistaken for temporary fatigue or “just weakness”, but in some cases they can escalate to a medical emergency. When glucose levels fall sharply, the brain–its primary fuel source–can become severely deprived of energy, sometimes triggering seizures that require urgent intervention.According to Dr Sreelakshmi N., Consultant – Neurologist and Epileptologist at S.L. When blood sugar levels drop to dangerously low amounts, it can disrupt normal brain function. This can cause electrical activity to become disorganized, which may lead to seizures, loss consciousness, or convulsions. If the condition is not treated, it can lead to permanent neurological damage. Consult your doctor before beginning any new routine. Why the brain is vulnerableUnlike other organs the brain cannot produce or store glucose on its own. When blood sugar drops rapidly, brain cells start to malfunction. When blood sugar levels drop dangerously low, the body may signal it with symptoms like blurred vision, headache, trembling, and more (Image: Pexels). The body can signal hypoglycaemia in newborns by exhibiting symptoms such as shakiness or blurred vision. It may also cause headaches, trembling or blurred vision. Alcohol on an empty tummy can also lower blood sugar levels. If these signs are missed, the condition can quickly progress to confusion, collapse, and seizures. ‘What are the noticeable physical signs that your insulin resistance is improving, such as changes in skin or weight?’Prevention and emergency responseExperts agree that prevention lies in maintaining stable glucose levels through consistent meal timing, correct medication use, and regular monitoring. High-risk individuals should not skip meals, match food intake to physical activity, and carry a source of sugar with them at all times. Continuous glucose monitoring devices can help detect sudden drops in blood sugar. It is important to always seek medical advice when making medication adjustments due to illness, travel or routine changes. “Emergency preparedness” is crucial for those who are prone hypoglycemia. The neurologist advises that patients be educated on early warning signs and to “keep a glucose powder and glucometer readily available at home.” Story continues below this advertisement”If blood sugar drops dissolve 3 teaspoons in water and drink immediately. If the patient is unconscious or unable to take orally, seek immediate medical care for intravenous glucose administration.”The neurologist further explains that long-term prevention strategies include” education and understanding personal triggers, medication adherence, alcohol, and medical identification” to reduce risks.With awareness, structured care, and early recognition of symptoms, hypoglycaemia-related seizures are largely preventable–turning a potentially life-threatening situation into a manageable one.DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.
