Chronic Obstructive Pulmonary Disease, or COPD, is a progressive lung disease that affects millions worldwide. Breathing difficulties, chronic cough, and other respiratory disorders define it. Although the core concept of COPD management lies in improving lung function and quality of life, more recent evidence indicates that systemic abnormalities, such as metabolic disorders like hypoglycemia, are related to the progression and clinical course of the disease in patients.
In this Blog, we’ll discuss in detail how low blood sugar may be associated with COPD.

Understanding COPD and its systemic effects

COPD has always been associated with systemic inflammation and oxidative stress. These factors affect the lungs and most of the body’s systems, such as metabolism. Disease conditions involve cardiovascular disease, diabetes, and muscle wasting. Given such relationships between respiratory and metabolic health, it is worth investigating how low blood sugar may affect COPD. Symptoms include persistent wheezing, chest infection, shortness of breath, and a chesty cough with phlegm that does not go away.

What Is Low Blood Sugar?

Hypoglycemia is when blood glucose levels fall below the normal range, usually less than 70 mg/dL. Symptoms of hypoglycemia can be mild or severe and include the following:

• Shaking or trembling
• Sweating
• Dizziness or lightheadedness
• Confusion
• Irritability or mood changes
• Rapid heartbeat

Severe hypoglycemia can cause seizures, unconsciousness, and even death if left untreated.

The Relationship Between COPD and Low Blood Sugar

Although COPD and hypoglycemia are two different diseases, some factors may connect to the former:

Corticosteroid Treatment

Corticosteroids are given to patients with COPD, decreasing inflammation and preventing its exacerbation. Long-term administration leads to resistance to insulin and changes in blood sugar levels. That may make some patients prone to hypoglycemia, especially when taken along with other drugs such as bronchodilators or beta-blockers.

Reduced Physical Activity

Many patients with COPD end up with low mobility related to breathlessness and severe fatigue. A sedentary lifestyle may influence metabolic pathways for glucose, where there is increased sensitivity toward insulin, thus increasing the risk for hypoglycemia.

Nutrition Deficiencies

Weight loss and malnutrition occur largely in patients with COPD. These conditions reduce glycogen levels inside the body and compromise its efforts to maintain normal blood sugar levels when fasting or ingesting decreasing calories.

Hypermetabolism

COPD often results in high energy expenditure due to labored breathing. This usually leads to an imbalance between energy intake and output, and blood sugar drops frequently occur, especially if dietary intake is inadequate.

Comorbid Conditions

Another major comorbidity observed in patients suffering from COPD is diabetes. The presence of COPD complicates the management of diabetes, and this combination can create difficulties in avoiding hypoglycemic episodes while administering treatment for both.

Overlapping Symptoms Hypoglycemia and COPD

It is difficult to diagnose hypoglycemia in patients suffering from COPD because the symptoms are dizziness, fatigue, and confusion, which are all the same symptoms that characterize exacerbations. This requires careful monitoring and differential diagnosis for the appropriate treatment.

Management of Hypoglycemia in COPD Patients

Management of hypoglycemia in patients suffering from COPD is holistic.

• Regular Checkup: COPD patients, particularly those who are diabetic or on a course of corticosteroids, should closely monitor their blood sugar levels with the help of CGM Devices.
• Balanced Diet: The diet must contain complex carbohydrates, proteins, and healthy fats. Patients who expend most of their energy can benefit from frequent, small-sized meals that control the sugar levels present in their blood.
• Medication Adjustment: Patients may need corticosteroid dose adjustment or changes in diabetes medication as supervised by a physician to prevent hypoglycemia.
• Exercise Planning: It is good to exercise, but one should do it according to the patient’s capacity and monitor him/her for sudden drops in blood sugar.
• Education and Awareness: Patients and caregivers should be informed about the signs of hypoglycemia and prompt management.

Need for More Research

Although the potential link between COPD and low blood sugar is quite appealing, further research is required to determine the mechanisms and implications of this association. Some research could be conducted on how different treatments affect blood sugar levels and the long-term results of managing hypoglycemia in COPD patients.

PGx Testing for Managing Low Blood Sugar in COPD

Pharmacogenomic (PGx) testing of RPh Labs can be crucial in managing low blood sugar in COPD patients by tailoring medication regimens to their genetic profiles. COPD treatment often involves corticosteroids and other medications that can influence glucose metabolism, potentially leading to hypoglycemia. PGx testing helps identify genetic variations that affect drug metabolism, efficacy, and side effects, allowing for personalized adjustments to medication choices and dosages. For example, PGx testing can advise on a safe administration of corticosteroids or diabetes in a patient with COPD without risking the potential to fluctuate blood sugars.

Conclusion

COPD is a complex systemic disease, and this novel association with low blood glucose further underscores the complex relationship between respiratory and metabolic well-being. Recognition and treatment of hypoglycemia in patients diagnosed with COPD can enhance their overall management and outcome at the hands of clinicians. The need for a truly multidisciplinary approach to care comes full circle relating to respiratory, nutritional, and metabolic expertise.
Pharmacogenomic (PGx) testing of Rph Labs offers a valuable tool to optimize the management of low blood sugar in COPD patients by enabling personalized treatment plans.
