The Silent Epidemic: Type 2 Diabetes

Diabetes affects millions of people in Nepal and South Asia, yet many are diagnosed only after complications have already developed. Type 2 diabetes is particularly deceptive — it can progress for years without obvious symptoms while quietly damaging your kidneys, eyes, nerves, and heart.

Knowing the early warning signs can help you seek diagnosis and treatment before serious damage occurs.

8 Early Warning Signs of Diabetes

1. Frequent Urination (Polyuria)

When blood sugar is high, the kidneys work overtime to filter and absorb the excess glucose. This leads to frequent urination, particularly at night (nocturia). If you find yourself waking up multiple times to urinate, it warrants investigation.

2. Excessive Thirst (Polydipsia)

Frequent urination causes dehydration, leading to constant thirst. You may drink large quantities of water but still feel thirsty. This cycle of thirst and urination is a classic early sign.

3. Unexplained Weight Loss

Despite eating normally or even more than usual, people with uncontrolled diabetes often lose weight. This happens because the body cannot use glucose for energy and starts breaking down fat and muscle instead.

4. Extreme Fatigue

When cells can't absorb glucose efficiently, they are starved of energy. This causes persistent fatigue that doesn't improve with rest.

5. Blurred Vision

High blood sugar causes the lens of the eye to swell, leading to blurred or fluctuating vision. This is often an early sign and should not be dismissed as just "eye strain."

6. Slow-Healing Wounds

Diabetes impairs blood flow and the immune response, causing even small cuts and bruises to heal slowly. Recurring skin infections or wounds that don't heal are a red flag.

7. Tingling or Numbness in Hands/Feet

Nerve damage (diabetic neuropathy) can begin early, causing tingling, numbness, or burning sensations in the extremities. This is often experienced as "pins and needles."

8. Darkened Skin Patches (Acanthosis Nigricans)

Dark, velvety patches of skin in the neck creases, armpits, or groin are a sign of insulin resistance — a precursor to Type 2 diabetes. This is particularly common in South Asian populations.

Risk Factors You Should Know

• Family history of diabetes
• Overweight or obesity (especially abdominal fat)
• Age over 45
• Sedentary lifestyle
• History of gestational diabetes
• Polycystic ovary syndrome (PCOS)
• High blood pressure or high cholesterol

How Is Diabetes Diagnosed?

A simple blood test can diagnose or rule out diabetes. At NITA Path Labs, we offer:

• Fasting Blood Sugar (FBS) — done after 8 hours of fasting
• Post-prandial Blood Sugar (PPBS) — done 2 hours after eating
• HbA1c — reflects average blood sugar over 3 months (no fasting required)
• Oral Glucose Tolerance Test (OGTT) — gold standard for diagnosis

Can Diabetes Be Prevented?

Lifestyle changes can significantly reduce the risk of developing Type 2 diabetes:

• Maintain a healthy weight — even losing 5–7% of body weight reduces risk substantially
• Exercise regularly — aim for 150 minutes of moderate activity per week
• Eat a balanced diet rich in fiber and low in refined sugars
• Avoid smoking and excessive alcohol
• Get regular screenings, especially if you have risk factors

Don't wait for symptoms to become severe. A simple blood test today could save you from a lifetime of complications.
