A blood sugar level of 216 mg/dL (milligrams per deciliter) is considered high. This level suggests the body’s glucose regulation may not be functioning optimally, warranting further attention and medical guidance.
Understanding a Blood Sugar Level of 216
Blood sugar, also known as glucose, is the body’s primary source of energy, derived from the foods consumed. Glucose circulates in the bloodstream, delivering fuel to cells throughout the body, including muscles and the brain. The hormone insulin, produced by the pancreas, helps glucose enter cells for energy or storage.
Healthy blood sugar levels fall within specific ranges, depending on when measured. A fasting level, after not eating for at least eight hours, is considered healthy if below 100 mg/dL. Two hours after a meal, a healthy level is less than 140 mg/dL.
A reading of 216 mg/dL is significantly above these healthy benchmarks. This level falls into the range associated with diabetes; a reading of 200 mg/dL or higher on a random or two-hour post-meal test suggests diabetes. For a fasting test, 126 mg/dL or higher indicates diabetes. While a single reading of 216 mg/dL strongly indicates elevated glucose, it does not provide a definitive diagnosis alone; confirmation requires additional tests.
Why Blood Sugar Levels Become Elevated
Blood sugar levels can become elevated due to temporary factors and persistent underlying conditions. Consuming a large meal, especially one high in carbohydrates or sugar, can lead to a temporary increase as the body processes glucose. Physical or emotional stress can also trigger hormones that raise blood sugar.
Illnesses, such as infections, can cause temporary elevations because the body releases stress hormones that interfere with insulin’s action. Certain medications, including corticosteroids and some diuretics, can lead to higher readings. A lack of adequate sleep can also affect insulin sensitivity, contributing to higher blood sugar levels.
Chronic conditions represent a persistent challenge to glucose regulation. Insulin resistance, where the body’s cells do not respond effectively to insulin, is a common cause of high blood sugar. The pancreas may also not produce enough insulin to meet the body’s needs, leading to elevated levels. These issues characterize type 2 diabetes. In type 1 diabetes, the pancreas produces little to no insulin.
What to Do After a High Blood Sugar Reading
Upon discovering a blood sugar reading of 216 mg/dL, re-test to confirm the initial reading. Observe for accompanying symptoms, such as:
- Increased thirst
- More frequent urination
- Unexplained weight loss
- Persistent fatigue
Maintaining calm helps in taking appropriate next steps.
Seeking medical attention is an important next step, especially if high readings persist or if symptoms of high blood sugar are present. A healthcare professional can conduct further diagnostic tests, such as an HbA1c test (providing an average blood sugar level over two to three months), a fasting plasma glucose test, or an oral glucose tolerance test. These tests provide a comprehensive picture of glucose metabolism and can lead to an accurate diagnosis.
Implementing lifestyle adjustments can support healthy blood sugar management. Adopting a balanced diet that limits refined carbohydrates, sugary drinks, and processed foods can help regulate glucose levels. Incorporating regular physical activity can improve insulin sensitivity. Maintaining adequate hydration and managing stress through techniques like mindfulness or meditation also contribute to better glucose control.
