When blood sugar levels are out of balance, it can manifest physically and emotionally. One common symptom is nausea, which can be a warning sign that something needs attention.
Maintaining optimal blood sugar ranges is crucial for overall health. According to the American Diabetes Association, fasting glucose levels below 100 mg/dL and post-meal glucose levels below 140 mg/dL are considered within normal limits (1). However, what happens when these ranges fluctuate? How does it impact our bodies?
The Causes of Nausea Due to Blood Sugar Fluctuations
Blood sugar spikes can lead to a condition known as reactive hypoglycemia. When the body rapidly increases insulin production in response to high blood glucose levels, there may be too much insulin available for optimal utilization (3). This can result in low blood sugar that triggers nausea and other symptoms.
In contrast, prolonged exposure to elevated blood sugars is associated with insulin resistance – a precursor to diabetes and cardiovascular disease. As this chronic state of hyperglycemia progresses, various bodily systems begin to break down, potentially leading to complications like organ damage (4).
Stabilizing Blood Sugar Levels through Dietary Adjustments
Certain foods can help regulate or spike blood sugar levels due to their high fiber content. Research has shown that consuming complex carbohydrates with moderate glycemic index values results in less pronounced postprandial glucose peaks and more stable insulin secretion over time.
Examples of these beneficial food groups include vegetables, whole grains, legumes, fruits like berries and citrus fruits (which contain citrate compounds), nuts and seeds rich in healthy fats. Limit foods high on the glycemic index scale – such as refined carbohydrates found in baked goods or instant products with a 'quick sugar release.'
