Ketones are acidic chemicals produced by the liver when the body breaks down fat for energy. This process is a natural part of metabolism, and low levels of ketones are present in everyone. In certain situations, however, the production of ketones can increase dramatically, leading to dangerously high levels known as ketoacidosis. This is a serious, life-threatening condition, particularly for people with diabetes, where it is known as diabetic ketoacidosis (DKA). Knowing the correct steps to take right away can make a critical difference in preventing a medical emergency.
Why High Ketones Require Immediate Attention
High ketone levels indicate that your body is not getting enough glucose (sugar) to use for fuel, and is instead breaking down fat at an accelerated rate. In diabetic individuals, this often occurs due to insufficient insulin. The resulting buildup of ketones makes the blood acidic, a toxic condition called ketoacidosis. DKA can develop rapidly, and its symptoms—which include excessive thirst, frequent urination, nausea, abdominal pain, and fruity-smelling breath—should not be ignored. Immediate medical intervention with fluids, insulin, and electrolytes is often necessary to correct DKA. For those without diabetes, high ketones can also occur due to prolonged starvation, illness, or excessive alcohol intake.
Immediate Actions to Lower Ketones for Diabetics
For individuals with diabetes, especially type 1, it is essential to have a pre-established "sick day" plan with your healthcare provider. The following steps are typical protocols for immediate action when ketones are detected:
-
Increase Fluid Intake: Stay Hydrated
One of the most critical steps is to drink plenty of fluids to help flush ketones out of the body through urine. If your blood glucose is high, opt for sugar-free fluids like water or sugar-free electrolyte drinks. If your blood glucose is normal or low, your doctor may advise drinking fluids containing sugar, such as juice, to provide carbohydrates for energy. Maintaining adequate fluid intake is important.
-
Administer Corrective Insulin Doses
If you have high ketones along with high blood glucose, your body needs more insulin. Administer an extra dose of rapid-acting insulin according to your sick day plan. Repeat testing as instructed by your healthcare team.
-
Test Frequently and Monitor Levels
Check your blood glucose and ketone levels regularly. A blood ketone meter provides a more accurate, up-to-the-minute reading than a urine test strip. Monitoring these levels is vital to confirm that your interventions are working and to know if you need to seek emergency care.
-
Avoid Strenuous Exercise
When your blood glucose and ketones are both high, avoid intense physical activity. Strenuous exercise can cause the body to burn more fat for fuel, potentially increasing ketone production and worsening the problem. Light activity is typically acceptable once ketones begin to fall, but consult your doctor for guidance.
Actions for Nutritional Ketosis and Other Causes
For individuals without diabetes who have high ketones due to a ketogenic diet, fasting, or illness, the approach differs slightly, though hydration remains key.
-
Reintroduce Carbohydrates
If you are on a low-carb diet and your ketone levels are higher than desired (but not at a dangerous DKA level), you can often bring them down by simply consuming more carbohydrates. This provides your body with glucose for fuel, reducing the need to burn fat and produce ketones.
-
Address Underlying Illness
If high ketones are caused by an illness, focus on treating the underlying condition while maintaining hydration. Persistent vomiting or diarrhea, in particular, requires increased fluid intake to combat dehydration and electrolyte loss.
-
Seek Medical Advice
Even if you don't have diabetes, high ketones accompanied by symptoms like persistent vomiting, shortness of breath, or confusion warrant a call to your healthcare provider.
Comparison of Action Plans: Diabetic vs. Nutritional Ketosis
| Action | Diabetic (High BG/Ketones) | Nutritional Ketosis (High Ketones) |
|---|---|---|
| Insulin | Administer corrective rapid-acting insulin dose per sick day plan. | Not applicable. Does not require corrective insulin doses. |
| Fluids | Drink sugar-free fluids (if BG high) or sugary fluids (if BG low). | Drink plenty of water and stay hydrated. |
| Carbohydrates | Manage carbs carefully; provide small amounts of sugary carbs if BG is low. | Increase carbohydrate intake temporarily to exit ketosis. |
| Exercise | Avoid strenuous exercise; rest is advised. | Avoid strenuous exercise; rest is advised if unwell. |
| Emergency Care | Seek immediate care for DKA symptoms (high ketones, vomiting, etc.). | Seek medical advice if concerned or unwell, though DKA is rare. |
Know When to Seek Emergency Care
For diabetics, certain signs and symptoms require immediate, emergency medical attention. These include:
- A very high blood ketone level.
- You have persistent vomiting for more than a few hours and cannot keep fluids down.
- You experience rapid, labored breathing.
- You feel confused, disoriented, or extremely fatigued.
- Your breath smells fruity, even after initial treatment.
If you have any of these symptoms, call for emergency medical assistance or go to the nearest emergency room immediately. Waiting can be life-threatening.
Conclusion: Act Fast and Know Your Triggers
In summary, understanding how to lower ketones immediately is a critical aspect of self-care, especially for those managing diabetes. The key is swift and appropriate action: test your levels, ensure adequate fluid intake, and take the correct amount of insulin as per your healthcare provider's guidance. For non-diabetics, a moderate increase in carbohydrates and addressing underlying issues can often resolve the situation safely. Always know your personal triggers, be it illness, missed insulin, or dietary changes, and have a clear action plan. In cases of very high ketones and alarming symptoms, never hesitate to seek emergency medical attention.
