Dehydration happens when your body loses more fluids than it takes in. Water makes up about 60% of your body1. Knowing the signs of fluid loss can help you avoid health problems.
Your body needs proper hydration to work right. When dehydrated, your normal body processes can get disrupted. Some people are more at risk, like babies, older adults, and those with long-term illnesses12.
Dehydration is more than just feeling thirsty. It can be mild or severe, with serious effects if not treated3. Kids are especially at risk. Mild dehydration in children occurs when they lose 3%-5% of their body weight from fluid loss3.
Key Takeaways
- Dehydration impacts body functions when fluid loss exceeds intake
- Water comprises about 60% of human body composition
- Different age groups have varying dehydration risks
- Mild to severe dehydration can have significant health impacts

Understanding Dehydration and Its Causes
Dehydration happens when your body loses fluids faster than it can replace them. It affects your body’s ability to work properly. Knowing about dehydration can help you stay healthy and avoid problems.
Your body constantly loses water through various processes. Replacing these fluids is vital. Electrolyte imbalance can occur when you’re dehydrated, disrupting normal body functions.
What is Dehydration?
Dehydration occurs when your body loses too much fluid. This imbalance affects many body systems. Older adults are at higher risk for dehydration complications.
The elderly face a 20% to 30% higher risk due to several factors. These include reduced mobility, impaired thirst, and chronic conditions like diabetes and kidney disease.
- Reduced mobility
- Impaired thirst mechanism
- Chronic conditions such as diabetes
- Kidney disease
Common Causes of Dehydration
Several factors can lead to dehydration:
- Excessive sweating during physical activity
- Prolonged exposure to hot environments3
- Illness with fever, diarrhea, or vomiting
- Increased urination
Risk Factors for Dehydration
Some people are more likely to lose fluids than others. Children and older adults face higher risks3. People working in tough environments are especially at risk.

When to Seek Medical Attention
Your body sends vital signals when it needs medical help. Watch for extreme thirst, no urination for 8 hours, rapid heartbeat, or fainting. These signs mean you need immediate medical care10.
Parents, be alert with infants and young children. No wet diapers for 3 hours, sunken eyes, or excessive sleepiness are red flags. These symptoms could signal a serious dehydration treatment emergency1011.
During a medical visit, doctors will assess your condition thoroughly. They may perform physical exams, urine tests, and blood work. Treatment can range from oral solutions to IV fluids10.
Untreated severe dehydration can cause serious health issues. These include heat injury, kidney problems, seizures, or hypovolemic shock. Older adults and those with chronic diseases face higher risks10.
Always put your health first. Seek medical help if symptoms persist or get worse.
