Diabetic Ketoacidosis (DKA)


Diabetic ketoacidosis (DKA) is a serious medical condition that can occur in people with diabetes if their blood sugar levels become dangerously high. It develops when the body cannot use glucose for energy and begins to break down fat instead, producing ketones.


DKA is most commonly caused by:

  • Missed or incorrect insulin injections: Insulin is a hormone that helps the body use glucose for energy. If insulin levels are too low, the body will not be able to utilize glucose effectively.
  • Infection: Infections can increase blood sugar levels and make it more difficult for insulin to work.
  • Trauma or surgery: Major events can stress the body and lead to increased blood sugar levels.
  • Heart attack or stroke: These conditions can cause a sudden increase in blood sugar levels.
  • Certain medications: Some medications, such as steroids, can raise blood sugar levels.

Risk Factors

Individuals with the following risk factors are more likely to develop DKA:

  • Type 1 diabetes
  • Poorly controlled blood sugar levels
  • Recent illness or infection
  • Limited access to insulin or medical care


DKA can progress rapidly, and it is crucial to recognize the symptoms early on. Common symptoms include:

  • High blood sugar levels (over 250 mg/dL)
  • Frequent urination
  • Excessive thirst
  • Dry mouth
  • Nausea and vomiting
  • Abdominal pain
  • Rapid breathing
  • Fruity-smelling breath (acetone breath)
  • Confusion or drowsiness


DKA is diagnosed based on a combination of symptoms, physical examination, and laboratory tests, including:

  • Blood glucose test
  • Ketone test
  • Arterial blood gas analysis
  • Electrolyte levels


DKA is a medical emergency that requires immediate treatment. Treatment typically involves:

1. Intravenous Fluid Resuscitation:

  • Fluids are administered to correct dehydration and restore electrolyte balance.

2. Insulin Therapy:

  • Insulin is given to lower blood sugar levels. This may be administered through an intravenous (IV) drip or injection.

3. Electrolyte Replacement:

  • Electrolytes such as potassium and sodium are replaced to correct imbalances.

4. Ketone Management:

  • Intravenous fluids and insulin help reduce ketone production.

5. Monitoring:

  • Patients are closely monitored for blood sugar levels, electrolyte balance, and other vital signs.


Untreated DKA can lead to severe complications, including:

  • Diabetic coma
  • Severe dehydration
  • Electrolyte imbalances
  • Heart arrhythmias
  • Cerebral edema (swelling of the brain)
  • Death


The best way to prevent DKA is to manage blood sugar levels effectively. This includes:

  • Regular insulin injections
  • Blood sugar monitoring
  • Healthy diet
  • Exercise
  • Infection prevention
  • Regular medical checkups


Diabetic ketoacidosis (DKA) is a serious medical condition that requires prompt treatment. Understanding the causes, risk factors, and symptoms of DKA is essential for early diagnosis and effective management. By adhering to treatment recommendations and following preventive measures, individuals with diabetes can reduce their risk of developing DKA and its associated complications.
