Diabetes Myths Busted: What I Hear Every Day in My Clinic

By Dr. Md. Mudassir Ali — Consultant Physician & Diabetologist, Faith Hospital, Hyderabad

Introduction: Why Diabetes Misinformation Is Dangerous

Every week in my clinic at Faith Hospital, I meet patients who have delayed treatment for months — sometimes years — because of something a neighbour, a WhatsApp forward, or a relative told them. Diabetes is one of the most common conditions I treat, and unfortunately also one of the most surrounded by myths.

Here is why this matters: uncontrolled diabetes silently damages your kidneys, eyes, nerves, and heart long before you feel anything wrong. By the time symptoms appear, much of the damage is already done. Misinformation, therefore, is not harmless — it directly costs people their eyesight, their kidney function, and sometimes their lives.

Let me bust the myths I hear most often.

Myth vs. Fact

Myth 1: "It's sugar-free, so I can eat as much as I want."

Fact: "Sugar-free" only means no added sucrose. Sugar-free biscuits, sweets, and chocolates are still made of flour (maida), fat, and refined carbohydrates — all of which raise your blood sugar. I have seen patients whose HbA1c went up after switching to "diabetic-friendly" products because they ate them without limit.

What to do instead: Treat sugar-free products as occasional treats, not free foods. Count total carbohydrates, not just sugar. A handful of nuts or a fruit is almost always a better snack than a pack of sugar-free biscuits.

Myth 2: "Bitter foods like karela and methi cure diabetes."

Fact: Bitter gourd (karela), fenugreek (methi), and jamun seeds may have a mild effect on blood sugar, but no food cures diabetes. Type 2 diabetes happens because of insulin resistance — a problem no single vegetable can reverse.

I have had patients stop their medicines because an aunty told them karela juice would "flush out the sugar." Within weeks, their sugars were in the 300s. Bitter foods can be a healthy part of your diet — but they are not medicine, and they are definitely not a cure.

Myth 3: "If the doctor puts me on insulin, my diabetes has become end-stage."

Fact: This is perhaps the most harmful myth of all. Insulin is not a punishment or a final stage — it is simply the most effective tool we have to bring sugars down quickly and protect your organs.

In reality:

• Many patients need insulin temporarily — during an infection, after surgery, or at diagnosis when sugars are very high.
• Starting insulin early can actually give your pancreas a chance to rest and recover. Some patients come off insulin later.
• Refusing insulin for years while sugars stay high is what leads to the complications people fear — kidney failure, blindness, amputations.

Insulin today is not what it was 20 years ago. Modern pens are discreet, nearly painless, and often need only one injection a day.

Myth 4 (bonus): "Diabetes medicines damage the kidneys."

Fact: It is usually the opposite — high blood sugar damages the kidneys, and some modern diabetes medicines (like SGLT2 inhibitors) actually protect them. Never stop a medicine based on a WhatsApp message; ask your doctor.

Why Early Treatment Matters — Protecting Kidneys, Eyes, and Nerves

Diabetes works silently. High glucose circulates through your blood and gradually damages the small blood vessels that supply your:

• Kidneys — diabetic kidney disease is the leading cause of kidney failure in India. It is detectable with a simple urine test years before it becomes serious.
• Eyes — diabetic retinopathy often has no symptoms until vision is already affected. An annual eye check-up can catch it early.
• Nerves — tingling, burning feet, or loss of sensation. Loss of feeling in the feet is why small wounds turn into serious infections.
• Heart — people with diabetes are two to four times more likely to have a heart attack.

The encouraging part: studies consistently show that good sugar control in the first years after diagnosis dramatically reduces all of these complications. Early treatment is an investment; delay is a debt that comes back with interest.

When to Get Tested — Beyond Fasting Sugar

Many people check only fasting sugar and assume that a "slightly high" reading is fine. Here is what I recommend understanding:

HbA1c — your three-month report card

HbA1c is a blood test that reflects your average blood sugar over the past 8–12 weeks. Think of it as your exam result — while a single fasting sugar is just one day's attendance.

• Below 5.7% — normal
• 5.7% – 6.4% — prediabetes (the window to act, see my next article)
• 6.5% or above — diabetes

Why it matters: your fasting sugar can look normal while your after-meal sugars are quietly high. HbA1c catches what a single reading misses. If you are on treatment, we typically check it every 3–6 months.

Who should be tested?

• Every adult above 30–35, at least once
• Earlier if you have a family history, are overweight (especially belly fat), have PCOS, had gestational diabetes, or have high BP
• Anyone with symptoms: excessive thirst, frequent urination, unexplained weight loss, slow-healing wounds, or repeated infections

Closing: Book a Diabetes Review

If you have diabetes and your last proper review was more than six months ago — or if you have been managing it on "advice" rather than medicine — please come see us. At Faith Hospital, we do a complete diabetes review: HbA1c, kidney and urine tests, and screening for the complications that matter, all under one roof.

Diabetes is not a life sentence — it is a condition you can control, provided you act on facts, not forwards.

Book an appointment with me at Faith Hospital — walk in or call us, and let's get your numbers where they should be.
