Dehydration — the body's lack of fluid — is a frequently underestimated risk, especially during the hot Mallorca summer. As a private medical house-call service in south-west Mallorca (Paguera, Port d'Andratx, Calvià), Doc-Mallorca treats dehydration / fluid loss directly at your hotel or finca — at flat rates of 350–450 €, with a personal callback from the doctor. At temperatures above 30°C / 86°F the body can lose up to 2 litres of sweat per hour. If this loss is not replaced, serious symptoms can develop quickly — and dehydration often goes hand in hand with sunstroke on holiday in Mallorca.
Symptoms
Strong thirst and dry mouth
Headache and dizziness
Tiredness and exhaustion
Dark urine (concentrated)
Dry skin, sunken eyes
Muscle cramps (calves, thighs)
First aid
1Move to a cool place immediately
2Drink water slowly (small sips)
3Oral rehydration solution or isotonic drink
4Salty snacks (crackers, pretzel sticks)
5Rest with the legs elevated
6Additionally apply cool compresses to forehead and neck
When to see a doctor
Warning — act immediately!
See a doctor immediately if: confusion, fainting, no urine output for 6+ hours, severe palpitations or impaired consciousness occur. Severe dehydration in children and elderly people can be life-threatening — call 112!
Prevention
Prevention tips
Drink 2.5–3 litres of water daily, increase to 4+ litres in heat or during sport. Avoid alcohol and caffeinated drinks. Wear a light hat and plan shaded breaks. If you experience acute weakness or circulatory problems, we can come to you with a house call in Palmanova.
When you should see a doctor
In case of confusion, fainting or circulatory collapse: call the European emergency number 112 immediately.
Come to a doctor: dizziness, little or very dark urine, ongoing weakness and circulatory problems — on-site infusion therapy can help. I come directly to you at your hotel, finca or holiday apartment — across the whole southwest of Mallorca, weekends included.
In summer at least 2.5–3 litres per day; in heat and during activity rather 4+ litres. Listen to your body — thirst is already an early warning sign.
Does beer count as fluid intake?
No, alcohol is dehydrating. When drinking beer the body actually loses more fluid than it takes in. For every beer, drink at least one glass of water.
What is better — water or sports drinks?
For normal hydration, water is enough. With heavy sweating (sport, sun) electrolytes matter — either isotonic drinks or water with a pinch of salt and some juice.
When does dehydration become dangerous?
From a fluid loss of about 5% of body weight (at 70 kg = 3.5 L). Then circulatory problems, impaired consciousness and kidney issues are possible.
💧 On-site treatment option
For pronounced dehydration, an intravenous infusion therapy is available directly at your hotel, villa or apartment — performed by a licensed German- and English-speaking physician.
For acute dehydration, examination and treatment are part of the house-call services — the flat-rate prices from €350 to €450 are transparent. My service base is Port d'Andratx, covering the whole southwest of Mallorca.
