I work outdoors in the heat. Can dehydration set off gout in my knee?

Why heat and gout go together

Uric acid is cleared mainly by the kidneys. When you sweat heavily and do not replace the fluid, urine output falls and uric acid rises. Crystals form more easily when its level is high, and a sudden change in level can also provoke a flare.

Outdoor and site workers in a Qatar summer, people who play football or padel in the evening heat, and anyone who goes long periods without drinking are all at higher risk, particularly if they have had gout before.

Practical steps for hot days

• Drink water regularly through the day rather than a large amount at once
• Watch your urine: pale yellow suggests you are drinking enough
• Limit sugary soft drinks, sweetened juices and energy drinks, as fructose raises uric acid
• Avoid alcohol, which raises uric acid and reduces its clearance
• Take breaks in the shade during the hottest hours and follow your employer's heat-safety rules
• If you have kidney or heart disease and are on a fluid limit, ask your doctor how much to drink

Ramadan and gout

Long fasting hours in warm weather, followed by large iftar meals, can trigger flares in some people. Common patterns are dehydration by late afternoon and heavy meals rich in red meat, organ meats, shellfish and sweet drinks after sunset.

People who fast often find it helps to spread water intake between iftar and suhoor, keep portions of meat and seafood moderate, and choose water or laban over sweetened drinks. If you take medicines for gout, discuss the timing of doses during Ramadan with your doctor before the month starts rather than stopping them. Questions about whether to fast with a medical condition can be discussed with your doctor and a scholar.

When to see a doctor in Doha

Seek care the same day for a hot, swollen knee with fever or if you cannot bear weight. If you have had two or more flares, it is worth discussing long-term uric acid-lowering treatment. At Aman Hospital Dr. Gelber assesses the knee, confirms the diagnosis and, where needed, coordinates with your GP or a rheumatologist on prevention.
