Diabetic ketoacidosis

Diabetic ketoacidosis (DKA) is a serious complication that can occur in people with diabetes. It develops when the body is unable to produce sufficient insulin, leading to a buildup of ketones in the bloodstream.

Understanding DKA

Insulin is a hormone that helps glucose, the body’s primary energy source, enter cells. Without enough insulin, the body begins to break down fat for fuel, resulting in the production of ketones. Ketones are acidic substances that can accumulate in the bloodstream, leading to DKA.

Recognizing DKA If you have diabetes or are at risk of developing diabetes, it’s crucial to be aware of the warning signs of DKA and seek immediate medical attention if you experience any of the following symptoms:

• Fruity breath odor
• Rapid breathing
• Increased thirst and urination
• Nausea and vomiting
• Abdominal pain
• Weakness or fatigue
• Confusion or altered mental state

Symptoms

Symptoms of DKA often develop rapidly, sometimes within 24 hours. For some individuals, these symptoms may be the first indication of diabetes.

Common Symptoms

• Excessive thirst
• Frequent urination
• Nausea and vomiting
• Abdominal pain
• Weakness or fatigue
• Shortness of breath
• Fruity-scented breath
• Confusion
• Diagnostic Tests

Home blood and urine test kits can help identify more definitive signs of DKA, including:

• High blood sugar level
• Elevated ketone levels in urine

Causes

• Insulin Deficiency: DKA occurs when the body is unable to produce or effectively use insulin, a hormone essential for glucose uptake into cells.
• Metabolic Imbalance: Without sufficient insulin, the body breaks down fat for energy, leading to the production of ketones. Ketones build up in the bloodstream, causing metabolic acidosis.
• Illness: Infections or other illnesses can increase the body’s production of hormones that counteract insulin, contributing to DKA.
• Insulin Therapy Issues: Missed insulin doses, inadequate insulin therapy, or malfunctioning insulin pumps can result in insulin deficiency and lead to DKA.
• Other Factors: Additional factors that may contribute to DKA include:
• Physical or emotional trauma
• Heart attack or stroke
• Pancreatitis
• Pregnancy
• Alcohol or drug misuse, particularly cocaine
• Certain medications, such as corticosteroids and some diuretics

Risk Factors

• Have type 1 diabetes: Individuals with type 1 diabetes are more susceptible to DKA due to their body’s inability to produce insulin.
• Frequently miss insulin doses: Missing insulin doses can lead to insulin deficiency and increase the risk of DKA.

Complications

• Hypoglycemia: Insulin therapy can cause blood sugar levels to drop too quickly, leading to hypoglycemia.
• Hypokalemia: The fluids and insulin used to treat DKA can deplete potassium levels, resulting in hypokalemia. Low potassium levels can affect the heart, muscles, and nerves.
• Cerebral Edema: Rapid adjustments to blood sugar levels, particularly in children with newly diagnosed diabetes, can increase the risk of cerebral edema, a swelling of the brain.

Prevention

• Effective Diabetes Management: Prioritize healthy eating, regular physical activity, and adherence to your prescribed diabetes medications or insulin regimen.
• Regular Blood Sugar Monitoring: Monitor your blood sugar levels frequently, especially during illness or stress. Aim for at least 3–4 daily checks or more as needed.
• Insulin Dosage Adjustment: Consult with your healthcare provider or diabetes educator to adjust your insulin dosage based on your blood sugar levels, diet, activity level, and overall health.
• Ketone Monitoring: When ill or stressed, use a urine ketone test kit to check for elevated ketone levels. If moderate or high levels are detected, seek immediate medical attention.
• Prompt Action: If you suspect DKA due to high blood sugar and elevated ketones, seek emergency care without delay.

When to see a doctor

• Illness or Stress: If you are feeling ill, stressed, or have recently experienced an illness or injury, monitor your blood sugar levels frequently.
• Persistent Vomiting: If you are unable to keep down food or liquids due to vomiting, seek medical attention.
• Elevated Blood Sugar: If your blood sugar levels exceed your target range and do not respond to home treatment, contact your healthcare provider.
• Elevated Ketone Levels: If your urine ketone levels are moderate or high, seek immediate medical assistance.

Seek Emergency Care If You Experience:

• Severely High Blood Sugar: Blood sugar level consistently above 300 mg/dL (16.7 mmol/L).
• Ketones in Urine & Inability to Contact Provider: If ketones are present and you cannot reach your healthcare provider.
• Multiple Symptoms of DKA: Including:
• Excessive thirst
• Frequent urination
• Nausea and vomiting
• Stomach pain
• Weakness or fatigue
• Shortness of breath
• Fruity-scented breath
• Confusion
