My Blood Sugar Is High, What Should I Do? A Step-by-Step Action Plan

Discovering that your blood sugar is high can be concerning, but it’s important to stay calm and take action. This step-by-step guide provides a comprehensive plan to help you manage the situation effectively. Remember to always consult with your healthcare provider for personalized advice.

Step 1: Check and Confirm Your Blood Sugar Levels

The first step is to confirm your blood sugar level using a reliable blood glucose meter. Here’s how:

  1. Gather Supplies: You’ll need your glucose meter, test strips, lancet device, and alcohol swabs.
  2. Wash Your Hands: Clean your hands thoroughly with soap and water and dry them completely. This ensures an accurate reading.
  3. Prepare the Lancet: Insert a new lancet into your lancet device.
  4. Insert Test Strip: Insert a new test strip into your glucose meter.
  5. Puncture Your Finger: Use the lancet device to prick the side of your fingertip.
  6. Apply Blood Sample: Gently squeeze your finger until a small drop of blood appears. Touch the test strip to the blood droplet.
  7. Read the Results: Wait for the meter to display your blood sugar level.
  8. Record the Result: Note down the date, time, and blood sugar reading.

If your blood sugar reading is higher than your target range (as advised by your doctor), proceed to the next steps. If it’s consistently high or accompanied by severe symptoms like confusion or difficulty breathing, seek immediate medical attention.

Step 2: Evaluate Potential Causes

Before taking any corrective action, try to identify the possible cause of the high blood sugar. Common causes include:

  • Dietary Imbalances: Consuming a meal high in carbohydrates or sugars.
  • Missed Medication: Forgetting to take your prescribed diabetes medication.
  • Illness: Infections or illnesses can cause blood sugar to rise.
  • Stress: High stress levels can affect blood sugar control.
  • Dehydration: Not drinking enough water.
  • Inactivity: Lack of physical activity.

Understanding the cause will help you choose the appropriate course of action.

Step 3: Take Immediate Corrective Actions

Depending on the severity of your high blood sugar, here are several immediate actions you can take:

  1. Drink Water: Dehydration can exacerbate high blood sugar. Drink plenty of water to help your kidneys flush out excess glucose.
  2. Light Exercise: Engage in a light physical activity like a brisk walk for 15-20 minutes. Exercise helps your body use glucose for energy.
  3. Check Medication Dosage: Ensure you’ve taken the correct dosage of your diabetes medication. If you missed a dose, take it as soon as you remember, unless it's close to the time for your next dose. In that case, skip the missed dose. Never double your dose.
  4. Dietary Adjustments: If the high blood sugar is due to a recent meal, avoid consuming more carbohydrates or sugary drinks.

Step 4: Re-check Your Blood Sugar

After taking corrective actions, re-check your blood sugar within 1 to 2 hours to see if the levels have decreased. This helps you monitor the effectiveness of your actions. Follow the same procedure as in Step 1 to ensure accuracy.

  • If Levels Are Decreasing: Continue to monitor your blood sugar every few hours to ensure they stabilize.
  • If Levels Remain High: Proceed to Step 5.

Step 5: Consider Additional Medication (If Prescribed)

  • Insulin: If you use insulin, follow your healthcare provider’s instructions for administering a correction dose based on your current blood sugar level.
  • Oral Medications: Some oral diabetes medications may also have a specific protocol for addressing high blood sugar. Refer to your doctor's instructions or the medication's guide.

Important: Never adjust or take additional medication without consulting your healthcare provider, especially if you are unsure about the correct dosage.

Step 6: Recognize When to Seek Medical Assistance

Knowing when to seek professional medical help is crucial. Contact your healthcare provider or seek immediate medical attention if:

  • Extremely High Blood Sugar: Your blood sugar is consistently above 300 mg/dL, even after taking corrective actions.
  • Symptoms of DKA: You experience symptoms such as nausea, vomiting, stomach pain, rapid breathing, fruity-smelling breath, or confusion (these are signs of Diabetic Ketoacidosis, a serious complication).
  • Unable to Keep Food or Drink Down: You are unable to keep down fluids, leading to dehydration.
  • Unresponsive or Losing Consciousness: You become unresponsive or start losing consciousness.

These situations require immediate medical attention to prevent serious complications.

Step 7: Prevention Strategies for the Future

After managing the immediate situation, focus on preventing future occurrences of high blood sugar. Key strategies include:

  1. Adhere to Your Meal Plan: Follow the dietary recommendations provided by your doctor or dietitian.
  2. Regular Exercise: Incorporate regular physical activity into your routine. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
  3. Medication Adherence: Take your medications as prescribed and on schedule.
  4. Consistent Blood Sugar Monitoring: Regularly monitor your blood sugar levels and keep a log to track patterns.
  5. Stress Management: Practice stress-reduction techniques such as meditation, yoga, or deep breathing exercises.
  6. Stay Hydrated: Drink plenty of water throughout the day.
  7. Regular Healthcare Check-ups: Attend regular appointments with your healthcare provider for ongoing management and adjustments to your treatment plan as needed.
