What is Diabetes — Complete Guide to Sugar Disease in Pakistan

What is Diabetes (Sugar Disease)?

Diabetes (medical term: diabetes mellitus) is a condition in which the level of glucose (sugar) in your blood rises above normal. This happens because your body either produces too little insulin or cannot use it effectively.

What is Insulin?

Insulin is produced in the pancreas (an organ near the stomach). It is a hormone that carries blood sugar into cells where it is used for energy. Think of insulin as the key that unlocks the door to your cells for glucose.

Types of Diabetes

1. Type 1 Diabetes (5–10% of Cases)

The pancreas produces no insulin at all. This is an autoimmune condition in which the body's immune cells attack and destroy the insulin-producing cells of the pancreas.

Key characteristics:

• Usually begins in childhood or young adulthood
• Insulin injections are required for life
• Symptoms develop suddenly
• Patients are often slim
• Family history is not always present

2. Type 2 Diabetes (90% of Cases)

The pancreas produces insulin, but the body's cells do not respond to it (insulin resistance). In Pakistan, 90% of diabetics have this type.

Key characteristics:

• Usually affects adults, but increasingly seen in teenagers
• Related to both lifestyle and genetics
• Symptoms develop slowly
• Family history is a strong predictor
• Patients are often overweight
• Manageable with diet, exercise, and medication

3. Gestational Diabetes

Diabetes that develops during pregnancy. It usually resolves after the baby is born, but increases the risk of developing Type 2 diabetes in the future.

4. Pre-Diabetes

Blood sugar is higher than normal but not yet in the diabetes range. Reversible with lifestyle changes.

Symptoms of Diabetes

Classic Symptoms (The Three P's):

• Polydipsia: Excessive thirst
• Polyuria: Frequent urination — especially at night
• Polyphagia: Excessive hunger

Other Common Symptoms:

• Unexplained weight loss without dieting (especially in Type 1)
• Constant fatigue
• Blurred vision
• Slow wound healing
• Recurrent fungal infections (genital area, mouth)
• Tingling or numbness in hands and feet
• Dry mouth
• Skin rashes
• Reduced sex drive
• Erectile dysfunction

Hidden Symptoms in Type 2:

In Pakistan, 50% of Type 2 diabetics are unaware of their diagnosis because symptoms develop slowly. It is often discovered on a routine blood test.

Causes of Diabetes

Type 1:

• Genetic predisposition
• Autoimmune attack on the pancreas
• Possible viral trigger
• Family history (less significant than in Type 2)

Type 2 (Common in Pakistan):

• Genetics: South Asian ancestry — high risk
• Family history: A direct relative with diabetes doubles your risk
• Obesity: Especially belly fat
• Physical inactivity
• Diet: White rice, white bread, sweets, soft drinks
• Age: 45 years and above
• History of gestational diabetes
• PCOS (in women)
• High blood pressure, high cholesterol
• Stress and poor sleep
• Smoking

Diagnosis of Diabetes

Tests:

HbA1c — The Most Important Test

HbA1c shows the average blood sugar level over the past 3 months. In Pakistan, it is recommended every 6 months for people with diabetes and those at high risk.

Complications of Diabetes

Untreated or poorly controlled diabetes leads to serious complications:

Acute (Sudden):

• DKA (Diabetic Ketoacidosis) — mainly in Type 1, life-threatening
• HHS (Hyperosmolar Hyperglycaemic State) — severely high blood sugar
• Hypoglycaemia — dangerously low blood sugar, often from medication overdose

Chronic (Long-term):

• Eye damage (retinopathy) — a leading cause of blindness
• Kidney damage (nephropathy) — the top cause of dialysis in Pakistan
• Nerve damage (neuropathy) — numbness in feet, foot ulcers
• Heart disease — heart attack risk 2–4 times higher
• Stroke risk 2–4 times higher
• Foot amputations — from diabetic foot ulcers
• Erectile dysfunction
• Increased susceptibility to infections

Risk Factors — Are You at Risk?

You should be tested for diabetes if any of the following apply:

• Age 40 or above
• Family history of diabetes
• Overweight (BMI 23+)
• Abdominal obesity (waist 90+ cm in men, 80+ cm in women)
• Previous gestational diabetes
• PCOS
• High blood pressure (140/90+)
• High cholesterol
• Sedentary lifestyle
• South Asian ancestry
• Pre-diabetes diagnosis

Diabetes and Pakistan

Why is there a diabetes epidemic in Pakistan?

• South Asian genetic predisposition — 2–4 times the risk of Europeans
• Diet: White rice, white bread, sweets, ghee — high glycaemic load
• Sedentary urban lifestyle
• Stress and poor sleep
• Low awareness
• Late diagnosis
• Affordability barriers for medications and monitoring

Prevention (Type 2)

Type 2 diabetes is preventable:

• Maintain a healthy weight (losing 5–10% of body weight reduces risk by 60%)
• Walk 30 minutes daily
• Healthy diet: Whole grains, vegetables, lentils, fish
• Reduce white rice and white bread
• Cut out sweets and soft drinks
• Annual screening after age 40
• Stress management
• 7–8 hours of sleep

Type 1 vs Type 2 — Quick Comparison

Conclusion

Diabetes is a silent epidemic in Pakistan that causes serious complications if left untreated. However, with early diagnosis and lifestyle changes, it is manageable — and even reversible in Type 2 at an early stage. Get an annual screening after age 40; those with a family history should test earlier. Chat with a doctor on Ilaaj AI for consultation and lab test guidance from home.
