Diabetes is a chronic health condition that affects how your body processes blood sugar (glucose). With millions of people worldwide living with diabetes, understanding its early signs and how it is diagnosed is crucial for timely intervention and effective management.

Common Symptoms of Diabetes

Diabetes can develop gradually, making it easy to overlook the early signs. Here are some common symptoms that may indicate the presence of diabetes:

1. Frequent Urination (Polyuria): High blood sugar levels cause the kidneys to work harder, leading to increased urination, especially at night.
2. Excessive Thirst (Polydipsia): Increased urination results in dehydration, triggering an intense feeling of thirst.
3. Unexplained Weight Loss: The body begins to break down fat and muscle for energy when it cannot use glucose effectively.
4. Increased Hunger (Polyphagia): Due to insulin resistance or insulin deficiency, cells do not receive enough glucose, leading to persistent hunger.
5. Fatigue: A lack of glucose in the cells for energy can cause continuous tiredness and weakness.
6. Blurred Vision: High blood sugar can cause swelling in the lenses of the eyes, leading to temporary vision changes.
7. Slow-Healing Wounds: High blood sugar levels can impair circulation and immune response, slowing down wound healing.
8. Tingling or Numbness in Hands and Feet: Over time, elevated blood sugar levels can damage nerves, leading to neuropathy.
9. Frequent Infections: High blood sugar weakens the immune system, making infections more common, particularly in the skin, gums, and urinary tract.
10. Darkened Skin Patches: Acanthosis nigricans, characterized by dark, velvety skin in body folds, can be an early sign of insulin resistance.

How Diabetes is Diagnosed

If you experience any of the above symptoms, it’s important to see a healthcare professional for proper diagnosis. The following tests are commonly used to diagnose diabetes:

1. Fasting Blood Sugar Test: Measures blood sugar levels after an overnight fast. A reading of 126 mg/dL or higher indicates diabetes.
2. Oral Glucose Tolerance Test (OGTT): After fasting overnight, blood sugar is tested, followed by drinking a sugary liquid. Blood sugar is tested again after two hours. A reading of 200 mg/dL or higher confirms diabetes.
3. Hemoglobin A1C Test: This test provides an average blood sugar level over the past two to three months. A result of 6.5% or higher suggests diabetes.
4. Random Blood Sugar Test: A blood sugar level of 200 mg/dL or higher at any time of the day, regardless of when you last ate, may indicate diabetes.
5. Urinalysis: While not a primary diagnostic tool, a urine test may detect ketones or high sugar levels, prompting further investigation.

Early Detection is Key

Recognizing the symptoms of diabetes early and seeking medical attention can prevent complications and improve quality of life. If you or a loved one experience any of these symptoms, consult a healthcare provider for appropriate testing and diagnosis. Managing diabetes through lifestyle changes, medication, and monitoring can help maintain optimal health and well-being.
