Blood Sugar Spikes After Pain Management in Diabetics - Internal Medicine

Factors Affecting Blood Glucose Levels


I would like to consult a doctor.
My mother has been experiencing lower back pain and has seen an orthopedic doctor.
She received an injection and is taking muscle relaxants.
Since my mother has diabetes, her blood sugar levels are regularly monitored, and her fasting blood sugar in the morning is around 120.
However, after the orthopedic visit, her blood sugar spiked to 250 the next day.
Is there a correlation between this and the treatment she received, or could it be due to pain and stress? Thank you, doctor.

Pain can cause an increase in blood sugar levels, and certain injections, such as steroids, can also raise blood sugar levels.
Thank you for your inquiry.

When managing diabetes, it is crucial to understand the various factors that can influence blood sugar levels, especially in the context of pain management. In your mother's case, the significant spike in blood sugar levels to 250 mg/dL following her treatment for back pain raises important questions about the interplay between pain, medication, and diabetes management.

Firstly, pain itself can lead to increased blood sugar levels. When the body is under stress—whether from physical pain or emotional stress—it releases stress hormones such as cortisol and adrenaline. These hormones can prompt the liver to release more glucose into the bloodstream, leading to elevated blood sugar levels. This phenomenon is often referred to as the "dawn phenomenon" or "stress-induced hyperglycemia." Therefore, it is plausible that your mother's pain and the associated stress contributed to her elevated blood sugar levels.

Secondly, the medications used for pain management can also impact blood sugar levels. Muscle relaxants and corticosteroids, if used, are known to affect glucose metabolism. Corticosteroids, in particular, can cause insulin resistance, leading to higher blood sugar levels. If your mother received a corticosteroid injection as part of her pain management, this could explain the spike in her blood sugar levels. It is essential to review the specific medications she was prescribed to determine if any of them are known to affect blood glucose levels.

Additionally, the timing of medication administration and the subsequent blood sugar monitoring is crucial. If her blood sugar was measured shortly after taking medication or receiving an injection, it might not accurately reflect her typical fasting levels. Blood sugar levels can fluctuate throughout the day, especially after meals or medication intake. Therefore, it is advisable to monitor her blood sugar levels at different times, including before and after meals, to get a clearer picture of how her body is responding to the treatment.

Furthermore, it is essential to consider dietary factors and overall diabetes management. If your mother’s diet was altered due to her pain or if she experienced changes in her appetite, this could also contribute to fluctuations in her blood sugar levels. Maintaining a balanced diet that is consistent with her diabetes management plan is vital for keeping blood sugar levels stable.

In conclusion, the spike in your mother's blood sugar levels following her pain management treatment is likely multifactorial, involving the stress response to pain, the effects of medications, and possibly changes in dietary habits. It is crucial to communicate these observations to her healthcare provider, who can assess her treatment plan and make any necessary adjustments. Regular monitoring of blood sugar levels, maintaining a consistent diet, and managing stress are all important components of effective diabetes management. If the elevated blood sugar levels persist or if she experiences any concerning symptoms, further evaluation and intervention may be necessary.
