Diabetes tidak sakit. Itulah sebabnya berbahaya. Apabila gula darah anda berlebihan secara konsisten selama bertahun-tahun, kerosakan berlaku perlahan-lahan dalam mata (retinopati), buah pinggang (nephropati), saraf (neuropati), dan saluran darah (penyakit jantung & strok). Bila simptom terasa, kerosakan biasanya sudah 5-10 tahun.
Diabetes doesn't hurt. That's why it's dangerous. When your blood sugar is consistently elevated over years, damage occurs slowly in your eyes (retinopathy), kidneys (nephropathy), nerves (neuropathy), and blood vessels (heart disease & stroke). By the time symptoms are felt, damage is usually already 5-10 years old.
Statistik Diabetes Malaysia
Diabetes Statistics — Malaysia
Mengikut National Health and Morbidity Survey (NHMS) 2023: 3.9 juta rakyat Malaysia menghidap diabetes (1 dari 5 dewasa). Hanya 51% tahu mereka pesakit. Yang lain mengetahui hanya bila komplikasi muncul. Diabetes adalah punca utama buta dewasa, kegagalan buah pinggang, dan amputasi kaki bukan-trauma di Malaysia. 10 tahun komplikasi boleh dicegah dengan saringan awal.
According to National Health and Morbidity Survey (NHMS) 2023: 3.9 million Malaysians have diabetes (1 in 5 adults). Only 51% know they have it. The rest only find out when complications appear. Diabetes is the leading cause of adult blindness, kidney failure, and non-traumatic foot amputation in Malaysia. 10 years of complications can be prevented with early screening.
7 Tanda Awal Diabetes — Yang Sering Diabaikan
7 Early Diabetes Signs — Often Overlooked
Tanda-tanda ini muncul perlahan dan boleh disalah-anggap sebagai "penat biasa" atau "tua dah". Tetapi kombinasi 2-3 tanda di bawah, atau mana-mana satu yang persisten lebih sebulan, wajib disahkan dengan ujian darah:
These signs appear slowly and can be mistaken as "just tired" or "old age." But combinations of 2-3 signs below, or any one persisting more than a month, must be confirmed with blood test:
- Polyuria — Kerap kencing, terutama bangun malam 2+ kali
- Polyuria — Frequent urination, especially waking 2+ times at night
- Polydipsia — Selalu dahaga, minum banyak air tapi tak puas
- Polydipsia — Constant thirst, drink lots but never satisfied
- Polyphagia — Selalu lapar walaupun baru makan
- Polyphagia — Always hungry even after eating
- Berat badan turun tanpa cuba — 3-5kg dalam sebulan tanpa diet
- Unintentional weight loss — 3-5kg in a month without dieting
- Penat tak hilang — letih sentiasa walau tidur cukup
- Persistent fatigue — always tired despite adequate sleep
- Penglihatan kabur — Saiz lensa mata berubah dengan paras gula
- Blurred vision — Eye lens shape changes with glucose levels
- Luka lambat sembuh — Calar kecil mengambil masa berminggu
- Slow-healing wounds — Small cuts take weeks to heal
- Mati rasa atau kesemutan di tapak kaki atau jari
- Numbness or tingling in feet or fingers
- Jangkitan kulat/yis berulang — kulat candidiasis, jangkitan saluran kencing
- Recurring fungal/yeast infections — candidiasis, UTI
- Gatal kulit tanpa sebab, terutama di pangkal paha
- Unexplained skin itching, especially at groin
- Mulut kering, nafas berbau acetone (manis aneh)

Pre-Diabetes — Tahap Reversible Yang Ramai Tidak Tahu
Pre-Diabetes — The Reversible Stage Many Don't Know
Sebelum diabetes "rasmi", ada tahap pre-diabetes (HbA1c 5.7-6.4%) di mana gula darah lebih tinggi dari normal tetapi belum mencapai paras diabetes. Tahap ini reversible dengan perubahan gaya hidup. Sayangnya, ramai tidak tahu mereka di tahap ini sehingga melepasi peringkat pre-diabetes:
Before "official" diabetes, there's a pre-diabetes stage (HbA1c 5.7-6.4%) where blood sugar is higher than normal but hasn't reached diabetes level. This stage is reversible with lifestyle changes. Sadly, many don't know they're at this stage until they pass it:
Ujian Saringan: HbA1c vs Gula Puasa — Mana Tepat?
Screening Test: HbA1c vs Fasting Glucose — Which Is Accurate?
HbA1c (glycated haemoglobin) memberikan purata gula darah anda dalam 2-3 bulan terakhir. Tidak perlu puasa, tidak terjejas oleh apa anda makan pagi tu. Ini ujian pilihan moden untuk diagnosis dan pemantauan. Kos di An-Nur: RM 35-50.
HbA1c (glycated haemoglobin) gives average blood sugar over last 2-3 months. No fasting required, not affected by what you ate that morning. This is the modern preferred test for diagnosis and monitoring. Cost at An-Nur: RM 35-50.
Gula puasa (FPG) hanya snapshot sehari tu — perlu puasa 8-12 jam. Lebih murah (RM 12-20) tetapi kurang akurat untuk diagnosis. OGTT (oral glucose tolerance test) digunakan jika hasil samar-samar atau untuk skrin diabetes gestasi pada ibu hamil. Untuk pesakit pertama kali, kombinasi HbA1c + gula puasa selalunya disyorkan untuk konfirmasi diagnosis.
Fasting glucose (FPG) is just a one-day snapshot — requires 8-12 hour fast. Cheaper (RM 12-20) but less accurate for diagnosis. OGTT (oral glucose tolerance test) used if results are ambiguous or for gestational diabetes screening in pregnant women. For first-time patients, combination HbA1c + fasting glucose is usually recommended for confirmation.
