When it comes to managing blood sugar levels, there's a common misconception that colds and flu are directly linked to high or low blood sugar readings. But is this truly the case? In today's article, we'll delve into the complexities of blood sugar fluctuations and separate fact from fiction.
The Impact of Cold on Blood Sugar Levels
Research suggests that respiratory infections like the common cold can indeed cause temporary fluctuations in blood glucose levels. When our body detects an invading pathogen, it mounts an immune response by releasing stress hormones such as cortisol and adrenaline into circulation (1). These hormones stimulate gluconeogenesis – a process where liver cells break down proteins to produce energy-rich glucose.
As your body fights off the infection, insulin sensitivity decreases due to inflammation caused by elevated cytokines. Insulin resistance is when our cells become less responsive to insulin's message of "store excess sugar," leading to higher blood sugar readings (2).
Role of Diet in Managing Blood Sugar
While diet plays a crucial role in maintaining stable blood glucose levels, certain foods can further disrupt this delicate balance during an infection. Foods high on the glycemic index like white bread and pasta cause rapid spikes in blood glucose (3). When you're sick with a cold or flu, avoid such food choices as they may worsen your condition.
Instead opt for fiber-rich complex carbohydrates found in fruits, vegetables, whole grains that slow digestion down; provide longer-lasting energy. Incorporate healthy fats like nuts seeds avocados olive oil to curb inflammation reduce blood sugar levels maintain optimal weight loss support mental health improve gut flora manage symptoms boost immunity prevent overeating cravings exercise hunger hormone leptin production (4).
The Link Between Blood Sugar and Infection
Chronic hyperglycemia, or consistently high blood glucose levels over time has been linked with an increased risk of infections. For example, research suggests that diabetes-related complications such as peripheral neuropathy can increase the severity and incidence of foot ulcers – a common complication in people with uncontrolled blood sugar (5).
This highlights why maintaining optimal blood glucose levels is crucial not only for managing but also preventing acute episodes like colds flu. By adopting healthy lifestyle habits exercise good nutrition stress management to control diabetes symptoms, you'll reduce risk overall disease burden related complications.
Blood Sugar Range and Overall Health
Your ideal daily blood sugar ranges vary depending on several factors age size weight activity levels medications you're currently taking; discuss these variables your healthcare provider or registered dietitian determine personalized target goal. However here's general guideline for non-diabetic individuals:
Normal Blood Glucose Range: Fasting (0-8 hours after waking): 70 mg/dL – 99 mg/Dl Post-meal: Less than 140mg/ d L
Conclusion
When you're down with a cold or flu, it's essential to keep in mind the impact that these illnesses can have on your blood glucose levels. While acute infections may temporarily disrupt insulin sensitivity and lead to high or low blood sugar readings, making smart lifestyle choices such as maintaining healthy diet stress-reducing habits will help regulate your body more efficiently.
