Unveiling the intricacies of high blood sugar, this comprehensive guide explores its impact on the body, delving into the diagnostic criteria, treatment options, and preventive measures. Through a scientific lens, we illuminate the path towards optimal blood sugar management.

Definition and Overview of High Blood Sugar

High blood sugar, also known as hyperglycemia, is a condition in which the glucose level in the bloodstream is abnormally elevated. Normal blood sugar levels range from 70 to 100 mg/dL (milligrams per deciliter) after fasting. High blood sugar is generally defined as blood sugar levels above 126 mg/dL after fasting or 180 mg/dL two hours after eating.

High blood sugar can be caused by various factors, including diabetes, certain medications, hormonal imbalances, and other medical conditions. In diabetes, the body either does not produce enough insulin (type 1 diabetes) or does not respond to insulin effectively (type 2 diabetes), leading to an accumulation of glucose in the bloodstream.

Symptoms and Complications of High Blood Sugar

Elevated blood sugar levels can manifest through various symptoms and potentially lead to severe complications if left untreated. Understanding these symptoms and their implications is crucial for managing and preventing high blood sugar.

Common symptoms associated with high blood sugar include:

  • Frequent urination: High blood sugar levels cause the kidneys to work harder to filter excess glucose, leading to increased urine production.
  • Increased thirst: Dehydration occurs due to frequent urination, resulting in excessive thirst.
  • Fatigue: High blood sugar can interfere with the body’s ability to use glucose for energy, leading to tiredness and fatigue.

Complications of Untreated High Blood Sugar

Prolonged high blood sugar levels can lead to serious complications, including:

  • Damage to the eyes: High blood sugar can damage the blood vessels in the retina, leading to diabetic retinopathy and potentially vision loss.
  • Kidney damage: Elevated blood sugar levels can damage the kidneys’ filtration system, leading to diabetic nephropathy and potential kidney failure.
  • Nerve damage: High blood sugar can damage nerves throughout the body, causing diabetic neuropathy and leading to numbness, pain, and weakness.

Monitoring blood sugar levels regularly is essential for preventing or managing these complications. By maintaining optimal blood sugar levels, individuals can reduce the risk of developing these severe health issues.
