The human body performs countless functions every day just to keep itself alive. Many of these functions involve the use of glucose (sugar) to fuel physical processes. However, when the level of sugar in your bloodstream goes out of control, you can experience everything from fainting spells to diabetes-related organ damage.
Just as drivers should understand some basic aspects of their vehicle's operation, you can benefit from knowing how blood sugar levels affect your health and what you can do to keep them under control. Here are some basic points to consider.
How Your Body Uses and Regulates Blood Sugar
Glucose serves as an energy source for many parts of the body, from muscles to major organs. The brain relies on glucose as its prime fuel for neurological function and thought processing. Your stomach and liver break down the foods you eat, releasing glucose into the bloodstream.
Under normal circumstances, your body uses a hormone called insulin to regulate the level of glucose in your bloodstream. The pancreas produces this substance on an as-needed basis. If the level threatens to drop too low, the pancreas makes another hormone, glucagon, to trigger the release of additional glucose.
How Blood Sugar Imbalances Occur
Sometimes the body loses its inherent ability to regulate blood sugar levels, which usually range from
70 to 100
milligrams per deciliter (mg/dL). Most cases of high blood sugar point to diabetes.
Diabetes can take several forms. In type 1 diabetes, the pancreas has lost its ability to produce insulin. In type 2 diabetes, the body builds up a resistance to the insulin produced by the pancreas until it can no longer make efficient use of it.
Type 1 diabetes occurs due to an auto-immune malfunction that destroys insulin-producing cells. Type 2 diabetes usually develops over time in response to obesity, poor diet, lack of physical activity, alcohol abuse, and other lifestyle factors that flood the body with too much sugar. Pregnant women may also develop diabetes temporarily.
Low blood sugar (hypoglycemia) sometimes occurs when medication for high blood sugar (hyperglycemia) proves too powerful in its effects. Alcohol abuse, anorexia, kidney disease, and glandular disorders can also produce hypoglycemia.
How Abnormal Blood Sugar Levels Affect the Body
Abnormal blood sugar affects the body in numerous ways. Hypoglycemia can deprive the body of so much energy that you feel dizzy, weak, hungry, shaky, and irritable. It can even cause seizures, vision problems, cognitive problems, and loss of consciousness.
Untreated high blood sugar may eventually damage nerves, blood vessels, and major organs. Typical complications include neuropathy (nerve pain, numbness, or tingling), poor wound healing, and irreversible vision loss. Earlier warning signs include dry mouth, frequent urination, fatigue, and sweet-smelling breath.
How to Treat Blood Sugar Problems
Milder cases of hyperglycemia usually respond to lifestyle changes such as a low-carbohydrate diet, regular exercise, and (if necessary) weight loss. Your doctor will want to check your blood sugar levels periodically to make sure that this regimen has succeeded in normalizing them.
If lifestyle changes cannot fix the problem, you may require medication to help your body regulate its blood sugar levels. These drugs may inhibit the breakdown of foods into sugars, help tissues absorb glucose, or stimulate extra insulin production. More severe cases may require insulin injections.
If you have hypoglycemia as well as diabetes, your doctor may need to change or adjust your diabetes medication to correct the problem. If you have hypoglycemia without also having diabetes, you can manage the condition by eating several small meals throughout the day and keeping sweets on hand for emergencies.
How to Prevent Future Blood Sugar Issues
Even if you currently enjoy stable blood sugar levels, you can reduce your risk for future problems by practicing a healthy lifestyle. For example, exercise boosts your insulin sensitivity, while weight control can help reduce the production of hormones that contribute to insulin resistance.
In addition to eating the correct portion sizes on the correct schedule, pay attention to the content of your diet. Foods rich in fiber and antioxidants both seem to boost unsling sensitivity.
