Diabetic Emergencies: Discussion of Nuances of Management

Diabetic emergencies are an increasingly pressing problem in sub-Saharan Africa, where the region has some of the fastest-growing rates of diabetes in the world. The International Diabetes Federation projects that the number of adults living with diabetes there will more than double over the next two decades, and an estimated majority of cases remain undiagnosed. For many patients, the first contact with the health system is a crisis: diabetic ketoacidosis (DKA), hyperosmolar hyperglycemic state (HHS), or severe hypoglycemia.

Type 1 diabetes in particular is often missed or misattributed to infection, malnutrition, or malaria, and children and young adults can present in advanced DKA after weeks of unrecognized symptoms. Case fatality for DKA in the region has historically been many times higher than in high-income countries, often cited in the range of 20 to 30 percent or more in some facility-based series, compared with 1 to 2 percent elsewhere. Delayed recognition is a major driver, along with limited access to insulin, glucometers, and ketone testing, and the fact that many first-line clinicians have had little training in endocrine emergencies.

Treating these emergencies well in resource-limited settings depends less on advanced technology than on systematic, protocolized basics: a bedside glucose check in any patient with altered mental status, early recognition of the clinical picture (deep rapid breathing, dehydration, abdominal pain, confusion), judicious fluid resuscitation, insulin dosing, and careful potassium monitoring or replacement where labs are available. Adapted protocols matter because standard guidelines assume continuous monitoring and rapid electrolyte turnaround that many facilities lack. Hypoglycemia is equally important, since it is fast, deadly, and easily reversed with dextrose or oral sugar, yet it is frequently overlooked, especially in patients on sulfonylureas or in malnourished or septic patients. Investment in clinician training, simple algorithms and checklists, point-of-care glucose testing, and reliable insulin supply chains can substantially reduce mortality. Equally important is the prehospital and primary care level, where community health workers, nurses, and first responders can identify a possible diabetic emergency, give glucose, and initiate timely transfer, closing the gap that so often determines whether a patient survives.
