Chronic Disease Management in Dubai's Climate
Dubai's extreme heat, with summer temperatures regularly exceeding 45°C, creates unique challenges for patients managing chronic conditions. Understanding how the climate affects your condition and medications is essential for staying healthy year-round.
Diabetes in the Heat
The UAE has one of the highest diabetes prevalence rates globally, affecting approximately 16% of the adult population. Heat adds specific complications:
Medication storage:
- Insulin must be kept below 30°C - carry in insulated cases when outdoors
- Metformin and other oral medications can degrade in hot cars
- Never leave medications in your vehicle, even briefly
Blood sugar fluctuations:
- Heat causes blood vessels to dilate, potentially increasing insulin absorption
- Dehydration concentrates blood glucose levels
- Reduced appetite in heat can lead to hypoglycaemia if medication isn't adjusted
Practical tips:
- Monitor blood glucose more frequently during summer
- Increase water intake to 3-4 litres daily
- Schedule outdoor activities for early morning or evening
- Keep fast-acting glucose readily available
- Wear medical identification
Hypertension and Cardiovascular Disease
Heat places significant stress on the cardiovascular system:
- Blood pressure drops in heat due to vasodilation, which may cause dizziness
- Diuretic medications increase dehydration risk
- Beta-blockers can impair the body's ability to cool itself
- ACE inhibitors may need seasonal dose adjustment
Management strategies:
- Home blood pressure monitoring (morning and evening)
- Discuss seasonal medication adjustments with your GP
- Maintain hydration without excessive salt intake
- Avoid sudden temperature changes (hot outdoors to cold AC)
- Regular cardiac check-ups before and after summer
