Early signs include dark urine, thirst, headache, and dizziness; severe signs include confusion, rapid heartbeat, no urine output, and fainting — seek immediate medical help for severe symptoms.
Deالترطيب is the leading cause of medical emergencies during الحج, and recognizing the signs early can be lifesaving. In the extreme الحرارة of مكة, your body can lose 1-2 liters of sweat per hour during physical activity, making it nearly impossible to keep up with fluid loss without deliberate effort. Early signs of mild deالترطيب include increased thirst, dry or sticky mouth, dark yellow urine, reduced urine output, headache, dizziness when standing up, fatigue, and dry skin. These are your body's first warnings to increase fluid intake immediately.
Moderate deالترطيب presents more alarming symptoms: very dark urine or urinating less than 3-4 times per day, rapid heartbeat, muscle cramps, sunken eyes, irritability, and a noticeable drop in energy. At this stage, water alone may not be sufficient — you need oral reالترطيب salts (ORS) to replace lost sodium, potassium, and other electrolytes. ORS sachets are available free of charge at most Saudi Red Crescent stations and health posts throughout the holy sites.
Severe deالترطيب is a medical الطوارئ requiring immediate professional treatment. Warning signs include confusion or disorientation, inability to keep fluids down due to vomiting, no urine output for 8 or more hours, extremely rapid or weak pulse, fainting or loss of consciousness, seizures, and skin that stays tented when pinched. If you or a fellow الحاج shows these signs, call 997 (Saudi الطوارئ services) or go directly to the nearest medical facility. Prevention is straightforward: drink at least 3-4 liters of water daily spread throughout the day, carry a water bottle at all times, eat water-rich fruits like watermelon and cucumber, and avoid prolonged sun exposure during peak hours.
