When it comes to blood sugar levels, most people are aware that high levels can be problematic. However, low blood sugar (hypoglycemia) is just as serious and requires prompt attention. A level of 12 mg/dL is considered severely low and may require medical intervention.

Severe hypoglycemia can lead to seizures, coma, or even death if left untreated. At this stage, the body's glucose levels are critically depleted, causing an insufficient supply of energy for vital organs. Symptoms include dizziness, confusion, weakness, tremors, sweating, and palpitations. If you experience any of these symptoms at a blood sugar level of 12 mg/dL or lower.

Dietary Factors That Influence Blood Sugar Levels

A well-balanced diet plays a crucial role in maintaining stable blood sugar levels. Certain foods are known to either raise or lower glucose levels in the body, and understanding their impact is essential for those with diabetes. Foods high on the glycemic index (GI), such as white bread, pasta, and baked potatoes, can cause a rapid increase in blood sugar due to their high carbohydrate content.

On the other hand, fiber-rich foods like fruits, vegetables, whole grains, and legumes tend to have a lower GI value and take longer for the body to digest. This helps slow down glucose release into the bloodstream. Regular consumption of these low-GI foods can help stabilize blood sugar levels over time.

How Exercise Affects Blood Sugar Levels

Regular physical activity is essential not only for maintaining good health but also in managing diabetes. When you exercise, your muscles use up more energy than usual, which stimulates your body to release glucose from stored sources into the bloodstream. At first glance, it might seem counterintuitive that exercising can actually increase blood sugar levels.

However, if done consistently and at a moderate intensity over time (aerobic activities like jogging or cycling), regular exercise helps improve insulin sensitivity – an important factor for effective glucose regulation in those with diabetes.

The Role of Insulin Sensitivity

Insulin sensitivity refers to how responsive your body is to the presence of insulin. In healthy individuals, cells readily take up glucose from the bloodstream when insulin levels are high and can effectively clear excess blood sugar when insulin decreases after a meal or between meals. However, in those with type 2 diabetes (and often type 1), chronic hyperinsulinemia develops.

As your body produces more and more insulin but becomes increasingly resistant to it, cells grow less responsive over time, impairing glucose uptake from the bloodstream. This phenomenon affects up to two-thirds of adults diagnosed with pre-diabetes or those at risk for developing diabetes by contributing significantly towards impaired blood sugar regulation.

Why Maintaining a Stable Blood Sugar Range Is Crucial

Maintaining stable blood sugar levels is critical because fluctuations can lead to chronic complications and put you at an increased risk of health problems, including cardiovascular disease (heart attacks/strokes), kidney damage/diabetes-related nerve disorders like foot ulcers or amputations in more severe cases.

It might be tempting to rely solely on medication management for those with type 1 diabetes; however, the majority – around 90% – have developed their insulin resistance through factors within reach: diet and lifestyle modifications offer hope as first line treatments that require no side effects or medical equipment beyond self-measured blood glucose meter (SMBG).
