Dehydration is a common condition that occurs when your body loses more fluids than it takes in. It can affect people of all ages and can lead to serious health complications if left untreated. Recognising the symptoms of dehydration is essential for prompt intervention and prevention of further health issues. In this comprehensive guide, we'll explore the various signs and symptoms of dehydration, its causes, and the importance of seeking timely medical attention.
What is dehydration?
Dehydration happens when your body loses more water than it’s taking in. And while a little thirst might not seem like a big deal, staying hydrated is crucial for everything your body does. Water helps maintain your body temperature, aids digestion, and even supports brain function. So when you’re not getting enough, your body starts to send out warning signs.
At first, it’s subtle, like a dry mouth or feeling a bit thirsty. But if you ignore those signs, things can get more serious. Maybe you’ve felt dizzy after a workout, noticed your heart racing, or felt light-headed on a hot day—that’s your body seeking water. And it’s not just athletes or people spending all day in the heat who need to be careful. Dehydration can hit anyone. Kids often don’t recognize the need to drink water until they’re already dehydrated. Older adults may not feel as thirsty, even when they’re low on fluids, making them more vulnerable. When dehydration gets really bad, serious complications can crop up, like kidney stones, urinary tract infections, or even heatstroke, which can be life-threatening.
What does water do for your body?
Water is essential for your body to function properly. It’s much more than just quenching your thirst—it plays a vital role in almost every process your body performs daily. Here's how:
- Regulates body temperature: Water helps your body stay cool by sweating, especially during hot weather or exercise. It keeps your internal temperature balanced.
- Aids digestion: Water is crucial for breaking down food, allowing your body to absorb nutrients efficiently and preventing constipation.
- Supports brain function: Staying hydrated keeps your brain sharp and boosts your focus, memory, and mood.
- Flushes out toxins: Water helps your kidneys filter out waste and keeps your body free from harmful toxins.
What are the signs and symptoms of dehydration?
Dehydration occurs when the body loses more water than it replaces. Dehydration symptoms can include:
- Thirst
- Dark yellow urine
- Urinating less often
- Dizziness or lightheadedness
- Tiredness
- Dry mouth lips, and tongue
- Sunken eyes
- Headache
- Muscle cramps
- Dry, cool skn
- Sunken soft spot on your infant’s head
- Dry and wrinkled skin
- High heart rate but low blood pressure
- Loss of appetite
- Swollen feet
What causes dehydration?
Dehydration is caused by insufficient water intake or excessive fluid loss. Causes of dehydration include intense physical activity, high temperatures, diarrhea, vomiting, and excessive sweating. Illnesses such as fever or diabetes can also lead to dehydration. Additionally, certain medications and alcohol consumption can increase fluid loss.
Dehydration among adults
Adults are susceptible to dehydration, especially during hot weather or when engaging in strenuous physical activity. Older adults and individuals with chronic illnesses are at higher risk. Symptoms of dehydration in adults may include:
- Dry mouth: A common early sign of dehydration.
- Fatigue: Feeling tired or sluggish due to a lack of fluids.
- Dark urine: Indicates concentrated urine, a sign you're not drinking enough water.
- Dizziness: Light-headedness often accompanies dehydration.
- Decreased urination: Going to the bathroom less frequently is a red flag.
- Rapid heartbeat: Your heart may race as a response to fluid loss.
Older adults and those with chronic illnesses are at a higher risk of dehydration. If you notice these symptoms, rehydrating promptly is essential to avoid serious complications like heatstroke or kidney damage.

Dehydration among children
Children are particularly vulnerable to dehydration due to their smaller body size and higher metabolic rate. Infants, in particular, can become dehydrated quickly, especially if they have vomiting or diarrhea. Signs of dehydration in children include:
- Dry lips: A noticeable sign of dehydration in children.
- Sunken eyes: A clear indicator of fluid loss.
- Decreased tears: Less tear production when crying signals dehydration.
- Dry tongue and mouth: A parched mouth is another common symptom.
- Lethargy: Tiredness or lack of energy may result from dehydration.
Infants and children, due to their smaller size and higher metabolic rate, are especially vulnerable to dehydration, particularly if experiencing vomiting or diarrhea. Immediate medical attention is crucial to prevent serious complications.
