Managing Type 1 Diabetes Ketones During Illness: A Practical Guide

Understanding Illness Ketones

• 💡 Illness ketones are a waste product from the body breaking down fat for fuel when it lacks sufficient insulin to manage high blood sugar, typically above 240-250 mg/dL.
• ⚠️ This process can lead to Diabetic Ketoacidosis (DKA), which can develop rapidly and be life-threatening, especially during illness.
• 🔬 Unlike nutritional ketosis or ketogenic diets, illness ketones are a sign of a serious metabolic imbalance.

Strategies for Ketone Management

• 💧 Hydration is crucial; aim for a water bottle per hour to help flush ketones from the body.
• 💉 When ketones are present with high blood sugar, extra insulin is needed beyond correction doses to clear them.
• 📊 The amount of extra insulin can be based on a percentage (5-15%) of total daily insulin or basal dose, depending on ketone severity (mild, moderate, large).
• 🍬 If blood sugar is low and ketones are present, consider taking in carbs without covering them with insulin, then bolusing for ketones separately.

Dealing with Nausea and Vomiting

• 💊 Medications like Zofran can help manage nausea, allowing individuals to keep down fluids and food.
• 🥤 If unable to keep food down, focus on hydration with water, electrolyte drinks, or even popsicles and honey to provide some energy.
• ⚠️ If vomiting is persistent, it's important to manage insulin carefully, potentially reducing carb boluses by 50-60% and waiting until food is retained before administering.

When to Seek Medical Help

• 🚨 Contact your endocrine team immediately if you have ketones, especially if blood sugars are high and not responding to treatment.
• 🏥 Go to the emergency department if blood sugars and ketones are not improving despite interventions, or if you suspect pump failure or severe dehydration/electrolyte imbalance.
• 🧐 Urine ketone strips provide outdated information; a blood ketone meter offers real-time, more accurate readings.

Managing Insulin Resistance During Illness

• 📈 During illness, the body often becomes insulin resistant, requiring significantly more insulin than usual, sometimes double the normal basal rate.
• ⏳ It takes experience and observation to manage these high insulin needs, often requiring continuous monitoring and adjustments.
• 🩹 Even with illness, monitor for potential issues like pump site failure which can exacerbate high blood sugar and ketone levels.
