What is Dehydration and What Causes It?
Dehydration is a condition that occurs when your body loses more fluids than it consumes, disrupting its normal functions. Dehydration can occur for various reasons, including:
- Not drinking enough water: This is the most common cause of dehydration.
- Strenuous exercise: Excessive sweating during exercise can lead to significant fluid loss.
- Diarrhea and vomiting: These can lead to rapid loss of fluids and electrolytes.
- Fever: Fever increases the rate of fluid loss from the body.
- Certain medications: Some medications, such as diuretics, can increase the risk of dehydration.
- Medical conditions: Certain medical conditions, such as diabetes, can increase the risk of dehydration.
What are the Signs and Symptoms of Dehydration?
The signs and symptoms of dehydration vary depending on its severity. Early signs of dehydration include:
- Extreme thirst
- Dry mouth
- Infrequent urination
- Dark-colored urine

If dehydration is not treated, the symptoms can progress to:

How is Dehydration Diagnosed?
Dehydration is usually diagnosed through a physical examination and assessment of symptoms. The doctor may also order blood and urine tests to check electrolyte levels and kidney function.

How Can Dehydration be Prevented?
Preventing dehydration is crucial for maintaining good health. Here are some tips for preventing dehydration:

- Avoid drinks that increase dehydration: such as drinks containing caffeine and alcohol.
- Be careful while exercising: Drink plenty of fluids before, during, and after exercise.
- Pay attention to the symptoms of dehydration: If you start to feel thirsty or dizzy, drink water immediately.
- For children and the elderly: Be more careful to ensure they get enough fluids, as they are more prone to dehydration.
Dehydration and Nutrition: What Foods Help with Hydration?
In addition to drinking water, some foods can help keep the body hydrated. These foods include:
- Watermelon: Contains a very high percentage of water (about 92%).
- Cucumber: Contains a high percentage of water and is rich in electrolytes.

Dehydration and Sports: How to Stay Hydrated During Exercise?
