Diabetic Ketoacidosis (DKA)
What is Diabetic Ketoacidosis (DKA)?
Diabetic ketoacidosis is a serious complication of diabetes that happens when your body doesn't have enough insulin. Without insulin, your cells can't use glucose for energy. Your body then breaks down fat instead, which creates acidic compounds called ketones.
When ketones build up too quickly in your blood, they make your blood acidic. This causes a dangerous condition that requires immediate medical attention. DKA most often affects people with type 1 diabetes, but it can also happen in people with type 2 diabetes.
DKA develops within 24 hours and can be fatal if not treated quickly. Blood sugar levels typically rise above 250 mg/dL. Your body tries to flush out excess sugar through urine, which leads to severe dehydration. Early recognition and treatment can prevent serious complications.
Symptoms
- Excessive thirst and frequent urination
- Nausea, vomiting, and stomach pain
- Fruity-smelling breath
- Rapid, deep breathing
- Extreme fatigue and weakness
- Confusion or difficulty concentrating
- Dry mouth and skin
- Flushed face
DKA symptoms develop quickly, usually within 24 hours. Anyone with diabetes who experiences these symptoms needs immediate medical care. Delaying treatment can lead to coma or death.

Causes and risk factors
DKA happens when insulin levels drop too low to allow glucose into your cells. Common triggers include missed insulin doses, illness or infection, and new diagnosis of diabetes. Physical or emotional stress increases your body's need for insulin. Certain medications, including corticosteroids and some diuretics, can also trigger DKA.
People with type 1 diabetes face the highest risk because their bodies produce little or no insulin. Type 2 diabetes patients can develop DKA during severe illness or stress. Other risk factors include insulin pump malfunction, heart attack, alcohol or drug use, and pregnancy. Young people with type 1 diabetes who skip insulin doses face particularly high risk.
How it's diagnosed
Doctors diagnose DKA through blood and urine tests that measure glucose, ketones, and acid levels. Blood glucose is typically above 250 mg/dL. Urine tests show high levels of both glucose and ketones. Blood tests also measure carbon dioxide levels, which drop when your blood becomes too acidic.
Rite Aid offers comprehensive testing that includes glucose and carbon dioxide measurements. Our panel can help you monitor your diabetes and catch warning signs early. If you have diabetes and feel unwell, seek immediate medical attention. Regular testing helps you understand your blood sugar patterns and prevent complications.
Treatment options
- Immediate hospital treatment with intravenous insulin to lower blood sugar and stop ketone production
- Fluid replacement through IV to restore hydration and flush out excess ketones
- Electrolyte replacement, especially potassium, to restore balance
- Treatment of underlying triggers such as infections
- Close monitoring of blood sugar, ketone, and electrolyte levels
- Education on proper insulin management to prevent future episodes
- Regular blood sugar monitoring at home, especially during illness
- Maintaining consistent insulin doses and meal schedules
- Developing a sick-day plan with your healthcare provider

Frequently asked questions
High blood sugar alone doesn't mean you have DKA. DKA occurs when high blood sugar combines with ketones and blood acidity. Your body produces ketones when it breaks down fat for energy instead of using glucose. This creates a dangerous acidic state that requires emergency treatment.
DKA typically develops within 24 hours, though it can happen faster in some cases. Symptoms may start gradually but worsen rapidly. Anyone with diabetes who experiences fruity breath, nausea, or confusion should check their blood sugar and ketones immediately. Early detection prevents life-threatening complications.
Yes, though it's less common than in type 1 diabetes. People with type 2 diabetes can develop DKA during severe illness, infection, or high stress. Some medications and medical conditions also increase risk. Anyone with diabetes should know the warning signs and seek immediate care if symptoms appear.
DKA typically occurs when blood sugar rises above 250 mg/dL, combined with ketones in blood or urine. However, some people develop DKA with lower glucose levels. The presence of ketones and blood acidity matters more than glucose levels alone. Testing for ketones is essential when blood sugar is elevated.
You can check for ketones using urine test strips available at most pharmacies. Dip the strip in urine and compare the color to the chart on the bottle. If you have moderate or high ketones with blood sugar above 240 mg/dL, call your doctor immediately. Some people also use blood ketone meters for more accurate results.
Common triggers include illness or infection, which increases insulin needs. Missed insulin doses or insulin pump problems also cause DKA. Stress, whether physical or emotional, raises blood sugar and ketone production. Some people develop DKA after surgery, injury, or during pregnancy.
Yes, most DKA episodes can be prevented with proper diabetes management. Take insulin as prescribed, even when you're sick or not eating much. Check blood sugar more often during illness or stress. Test for ketones when blood sugar is above 240 mg/dL. Create a sick-day plan with your healthcare provider.
Most people recover within 24 to 48 hours with proper hospital treatment. You'll receive insulin and fluids through an IV until ketones clear and blood chemistry normalizes. After leaving the hospital, you may feel tired for several days. Full recovery depends on how severe the episode was and how quickly treatment began.
Untreated DKA can lead to brain swelling, kidney failure, and loss of consciousness. Severe dehydration damages organs and can cause shock. Low potassium levels from treatment can affect heart rhythm. DKA can be fatal without emergency care, which is why recognizing symptoms early is critical.
Never skip insulin when you're sick, even if you're not eating normally. Illness increases your insulin needs, not decreases them. Check blood sugar and ketones every 4 hours during illness. Follow your sick-day plan, which should include when to call your doctor and how to adjust insulin doses.
