Today Dr. Abhishek Shukla explained why patients with diabetes can suddenly lose consciousness when their blood sugar drops below 50 mg/dL, a condition known as severe hypoglycaemia. At this level, the brain is deprived of glucose, leading to symptoms like sweating, tremors, confusion, seizures, and eventually unconsciousness if not corrected immediately. Hypoglycaemia is a medical emergency and often happens in patients who take insulin or oral hypoglycaemic medicines, especially if they skip meals, exercise excessively, or have kidney/liver issues.
Dr. Abhishek highlighted that immediate management is crucial. In an unconscious patient, an IV line should be established without delay, followed by the administration of 25% dextrose to rapidly raise blood glucose levels. If IV access is not possible, a glucagon injection is the next best option because it quickly stimulates the liver to release stored glucose. Caregivers should never try to give food or liquids orally to an unconscious person due to the risk of choking.
He further discussed DKD (Diabetic Kidney Disease), explaining how uncontrolled diabetes over time damages the small blood vessels of the kidneys. This leads to protein leakage in urine, rising creatinine levels, and eventually chronic kidney disease. DKD increases the risk of both hypoglycaemia and hyperglycaemia because impaired kidneys cannot properly metabolize medications. Regular monitoring, controlled sugars, kidney-friendly medications, and timely specialist intervention is important to prevent progression.
