High blood sugar levels, also known as hyperglycemia, can have severe consequences on the body. When left unmanaged or untreated, it can lead to life-threatening complications such as diabetic ketoacidosis (DKA), a condition characterized by high blood glucose and increased ketone production.
Understanding Normal Blood Sugar Ranges
For adults without diabetes, normal blood sugar ranges are typically between 70-99 mg/dL after an overnight fast. However, for those with diabetes or prediabetes, the American Diabetes Association recommends maintaining a before-meal blood sugar range of less than 180 mg/dL and a two-hour postprandial (after meal) range below 140 mg/dL.
The Consequences of Prolonged High Blood Sugar
Prolonged high blood sugar levels can damage organs such as the kidneys, heart, eyes, and nerves. For instance, DKA is a medical emergency that requires immediate attention to prevent serious complications like brain swelling or even death.
Managing Blood Sugar Through Diet and Exercise
A healthy diet rich in fruits, vegetables, whole grains, lean proteins, and low-fat dairy can help regulate blood sugar levels. The Academy of Nutrition and Dietetics recommends incorporating foods high on the glycemic index (GI) gradually to minimize insulin resistance.
Blood Sugar Fluctuations During Pregnancy
Women with gestational diabetes should aim for a preprandial range of 95 mg/dL or less and postprandial targets below 140-180 mg/dL. Regular exercise, healthy eating habits, and monitoring blood sugar can help maintain stable ranges during pregnancy.
Why Blood Sugar Control is Crucial for Heart Health
High blood pressure is more prevalent in people with uncontrolled diabetes due to insulin resistance's effect on vascular health. A study published in the Journal of Clinical Endocrinology & Metabolism found that each 10% reduction in HbA1c levels over six months resulted in a significant decrease (5%) in cardiovascular events.
Avoiding Common Mistakes When Managing Blood Sugar
For individuals with diabetes or prediabetes, it's crucial to not ignore warning signs of high blood sugar such as excessive thirst and urination. Keeping track of daily food intake, medication adherence, exercise routine, and regular check-ins with healthcare professionals are essential components of effective management.
Maintaining a Healthy Blood Sugar Range Through Sleep
Prolonged sleep deprivation can cause cortisol levels to increase, thereby worsening insulin resistance. Establishing an 8-hour sleep schedule is crucial for maintaining stable blood sugar ranges.
