Type 2 diabetes — diagnosis, treatment and long-term care in Dubai
Also known as: T2DM
Type 2 diabetes develops when the body no longer responds properly to insulin, so blood sugar rises. It is diagnosed with repeated HbA1c or fasting glucose blood tests. Treatment combines nutrition, activity, weight, sleep and — where needed — medicines, with regular reviews of the eyes, kidneys, feet and heart.
- · Diagnosis needs repeated HbA1c or fasting glucose testing, not a single reading
- · Most people are managed in primary care with lifestyle change and medicines
- · Regular reviews check eyes, kidneys, heart, feet and mood
- · Early type 2 diabetes may go into remission with sustained weight change
- · Emergency care is needed for very high sugars with vomiting, drowsiness or confusion
What type 2 diabetes is
Type 2 diabetes is a long-term condition in which insulin resistance and reduced insulin production combine to raise blood glucose. Unlike type 1 diabetes, it is not autoimmune. It develops silently over years and often coexists with high blood pressure, raised cholesterol and fatty liver.
How common it is
The IDF Diabetes Atlas estimates around 1 in 5 adults in the UAE are living with diabetes and a further large proportion have prediabetes. Prevalence is higher in adults with South Asian, Arab and Middle Eastern ancestry.

- · Dark, velvety skin at the neck or armpits (acanthosis nigricans)
Causes
- · Genetic predisposition

- · Diagnosis is not made on a single result unless symptoms are clear and glucose is very high

Treatment
Overview
- · Personalised nutrition plan (lower refined carbohydrate, Mediterranean pattern often preferred)
- · Structured physical activity, including resistance exercise
- · Weight management where indicated
- · Sleep and stress support
- · Medicines when lifestyle alone is not enough
- · Regular monitoring of HbA1c, blood pressure, lipids, kidney function and feet
Medicines
- · Metformin is usually first-line unless not tolerated or contraindicated
- · SGLT2 inhibitors and GLP-1 receptor agonists are increasingly used, especially when cardiovascular or kidney disease is present, or weight loss is a priority
- · Sulphonylureas, DPP-4 inhibitors and insulin have specific roles
- · Medication choice is a shared decision — never stop or change diabetes medicines without discussing with your clinician
Do not stop or change any prescribed medicine without first discussing it with your clinician.
Lifestyle support
- · Structured doctor-led dietary advice tailored to your health risks
- · 150 minutes/week moderate activity plus 2 sessions of resistance training
- · Smoking cessation and reduced alcohol intake
- · Sleep of 7–9 hours where possible
- · Stress management strategies
Monitoring and follow-up
- · HbA1c every 3–6 months while treatment is being adjusted, then every 6–12 months
- · Annual review of kidneys (eGFR, ACR), lipids, blood pressure, feet and eyes
- · Mental health screening at review, as diabetes and low mood commonly coexist
Prevention and risk reduction
- · Screening for prediabetes in at-risk adults
- · Sustained weight change and activity
- · Treating high blood pressure and cholesterol early
- · Avoiding unnecessary long courses of steroid medicines
When to seek urgent help
- · Blood glucose above 15 mmol/L with vomiting, drowsiness or rapid breathing
- · Chest pain, one-sided weakness or slurred speech — call 998
- · New foot ulcer, sudden vision loss or severe abdominal pain
Dubai emergency services: 998. Attend the nearest emergency department for red flags.

Frequently asked questions
Can type 2 diabetes be reversed?+
Early type 2 diabetes can go into remission for some people with sustained weight loss and dietary change. It is not a cure and needs ongoing monitoring to detect any return of raised blood sugar.
Do I need insulin?+
Most people with type 2 diabetes do not need insulin at diagnosis. It is considered when other medicines are not enough or in specific clinical situations.
How often should HbA1c be tested?+
Every 3–6 months when treatment is being adjusted, then every 6–12 months once stable.
Can I fast during Ramadan?+
Many people with well-controlled type 2 diabetes can fast safely with a personalised plan and medication adjustment. Discuss this with your GP before Ramadan.
