Essential Tips for Diabetes Patients on Insulin Injections

What should diabetic patients pay attention to when injecting insulin?

Hello Dr.
Kuo,
I would like to ask about the precautions that diabetic patients should take when injecting insulin.
Is it necessary to measure blood glucose levels daily? If a patient does not measure their blood glucose levels daily and still injects insulin, what impact could this have on their health? Thank you for your time and response.

For diabetic patients receiving insulin therapy, insulin injection serves as a hormone replacement therapy to compensate for insufficient insulin production.
The principle of insulin injection is to closely mimic the normal secretion of insulin by the pancreas, and insulin dosage must be adjusted based on monitored blood glucose levels.
However, current insulin formulations and injection systems do not yet achieve the ideal function of a normal pancreas.
Blood glucose measurement provides the most concrete data for both patients and physicians, aiding in determining the appropriate dosage, timing, and type of insulin to be used.
Each diabetic patient has unique characteristics influenced by factors such as individual insulin secretion capacity, insulin sensitivity, lifestyle, activity level, and dietary habits, leading to variations in insulin treatment approaches.
Therefore, insulin therapy is individualized and may involve one to four injections per day.
It is crucial not to apply someone else's insulin regimen to oneself, as this can be dangerous.
Since insulin is destroyed by gastric acid, it must be administered via injection and cannot be taken orally; however, inhaled insulin is expected to be available in the near future.

When it comes to managing diabetes, particularly for patients who require insulin injections, there are several essential tips and considerations that should be followed to ensure effective treatment and minimize the risk of complications. Here are some key points to keep in mind:
1. Understanding Insulin Therapy: Insulin is a hormone that regulates blood sugar levels. For individuals with diabetes, especially Type 1 diabetes or advanced Type 2 diabetes, insulin therapy is crucial. It is important to understand that insulin therapy aims to mimic the natural insulin secretion of the pancreas. This means that the timing and dosage of insulin injections should be tailored to the individual's needs, which can vary based on factors like diet, physical activity, and overall health.

2. Daily Blood Sugar Monitoring: Regular blood glucose monitoring is vital for anyone on insulin therapy. It helps patients and healthcare providers understand how well the current treatment plan is working. Ideally, blood sugar levels should be checked multiple times a day, including before meals and at bedtime. If a patient does not monitor their blood sugar daily and simply injects insulin, they risk experiencing hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), both of which can lead to serious health complications.

3. Adjusting Insulin Dosage: Insulin dosages may need to be adjusted based on blood sugar readings, dietary intake, and physical activity levels. For instance, if a patient notices that their blood sugar is consistently high before meals, they may need to increase their insulin dosage. Conversely, if they experience frequent low blood sugar episodes, they may need to decrease their dosage. This adjustment should always be done under the guidance of a healthcare professional.

4. Injection Technique: Proper injection technique is crucial to ensure that insulin is absorbed effectively. Patients should rotate injection sites to prevent lipodystrophy (fat tissue changes) and ensure consistent absorption. Common injection sites include the abdomen, thighs, and upper arms. It is also important to clean the injection site with alcohol swabs and allow it to dry before injecting.

5. Recognizing Hypoglycemia: Patients should be educated on the signs and symptoms of hypoglycemia, which can include shakiness, sweating, confusion, irritability, and dizziness. It is essential to have a source of fast-acting carbohydrates on hand, such as glucose tablets or sugary drinks, to treat low blood sugar quickly.

6. Diet and Exercise: A balanced diet and regular physical activity are integral components of diabetes management. Patients should work with a registered dietitian to develop a meal plan that aligns with their insulin regimen. Exercise can also affect blood sugar levels, so patients should monitor their blood sugar before and after physical activity.

7. Regular Medical Check-ups: Regular follow-ups with healthcare providers are essential for monitoring diabetes management. This includes checking HbA1c levels, which provide an average blood sugar level over the past two to three months, and assessing for any complications related to diabetes.

8. Education and Support: Diabetes management can be overwhelming, and patients should seek education and support from healthcare professionals, diabetes educators, and support groups. Understanding the disease and treatment options can empower patients to take control of their health.

In summary, insulin therapy is a critical aspect of managing diabetes, and patients must be diligent about monitoring their blood sugar levels, adjusting their insulin dosages as needed, and following proper injection techniques. By adhering to these essential tips and maintaining open communication with healthcare providers, patients can effectively manage their diabetes and reduce the risk of complications.
