Diabetic ketoacidosis (DKA)
Diabetic ketoacidosis is a life-threatening complication of diabetes where the body produces excess blood acids called ketones due to a lack of insulin. It primarily affects people with type 1 diabetes and requires immediate medical intervention.
Overview
Diabetic ketoacidosis is a life-threatening complication of diabetes where the body produces excess blood acids called ketones due to a lack of insulin. It primarily affects people with type 1 diabetes and requires immediate medical intervention.
Understand this condition
When the body lacks insulin, sugar stays in the blood instead of entering cells for energy. To compensate, the body burns fat for fuel, which creates acidic waste products called ketones. High levels of ketones change the blood's pH, disrupting the function of vital organs.
Why it happens
A lack of insulin triggers the release of stress hormones that cause the body to burn fat storage too quickly. This results in a buildup of ketones and high blood sugar, leading to severe dehydration and chemical imbalances. It usually progresses rapidly within hours after insulin levels drop significantly.

- •Arterial blood gas (pH levels)
- •Electrolyte panel (potassium, sodium)
Treatment options
General educational information only — no dosage advice. Always follow guidance from a qualified clinician.
- •Insulin therapy to lower blood sugar and ketones
- •Electrolyte replacement (especially potassium)
- •Treatment of underlying infection if present
- •DKA cannot be treated at home
- •seek hospital care immediately
- •Sip sugar-free fluids if waiting for transport
- •Monitor blood sugar closely during illness
- •Do not stop insulin without medical advice
- •Intravenous (IV) fluids for rehydration
Complications
- •Long-term damage if untreated
- •Reduced quality of life
- •Worsening symptoms over time
- •Recurrence of diabetic ketoacidosis (dka)
Prevention
- •Maintain a healthy lifestyle
- •See a clinician for routine check-ups
