Dehydration: Symptoms and Prevention

Have you ever felt extreme thirst or felt dizzy with less frequent urination? Then chances are that you are dehydrated. Dehydration generally happens when your body doesn't have enough fluids for its normal functions. When the problem becomes frequent, it raises the risk of infections and even affects your kidneys. Dehydration can be especially risky for children or older adults and often leads to serious complications if ignored.

So if you’ve been brushing off the dehydration symptoms like a parched throat or dry mouth, this guide is for you. We'll walk you through what causes dehydration, its symptoms, effects, and prevention tips.

What is Dehydration?

Dehydration occurs when your body loses more fluids than you take in. It commonly happens when you do not consume enough fluids, especially in hot weather. 

Children also face dehydration after diarrhoea and vomiting or inadequate intake of fluids during illness. It also occurs in older adults due to lower body water content and the use of certain medications. Mild dehydration can be easily treated by drinking water but a more severe type may require medical intervention. 

What Are the Different Levels of Dehydration?

Dehydration can be mild, moderate, or severe, based on severity. Let’s discuss them in detail below:

Mild Dehydration (3-5% Water Loss)

It is a very early-stage condition where your body loses slightly more water than it usually takes in. You can overcome this type of dehydration by drinking sufficient water or fluids. You can also drink electrolytes if it is followed by severe vomiting, diarrhoea or sweating, you can also drink electrolytes. 

Moderate Dehydration (6-9% Water Loss)

It is an intense fluid deficit that causes intense thirst, dark urine, dizziness, and rapid heartbeat. This dehydration type requires you to intake intravenous fluids for your hydration needs. You might also have to visit a clinic or a hospital for treatment.

Severe Dehydration (>10% Water Loss)

It is usually considered a medical emergency when the body losses a huge amount of fluids or electrolytes. This should be considered a medical emergency which needs immediate attention from healthcare providers. 

What are the Common Dehydration Symptoms?

The symptoms of dehydration differ by age and affect nearly 17-28% of individuals. The most common symptoms you can experience are: 

What Causes Dehydration?

There are several causes of dehydration, but the most common ones are discussed below:

Insufficient Water Intake

Not drinking enough water is one of the primary reasons your body gets dehydrated. For healthy individuals, the average daily water intake is 15.5 cups for men and 11.5 cups for women. However, this amount also differs depending on their activity level, health status, and weather conditions.

Diarrhoea

Severe diarrhoea accompanied by vomiting can cause excessive fluid loss from the body. This creates a loss of water and important body salts (electrolytes). If this happens, you must drink sufficient water and also consider consuming oral rehydration solution to bring back the lost minerals.

Fever

A fever raises your body temperature, which can lead to dehydration. The higher the fever, the more fluids you lose. Even mild illnesses like a cold can cause dehydration because they make you feel less hungry and thirsty.

Sweating

It's generally your body’s way to release heat and cool down during hot weather or intense exercise. Your muscles also pump up during exercises and the same heat is released through sweating. However, excessive sweating can cause dehydration and water imbalance in your body.

Diabetes

Unmanaged or uncontrolled diabetes can also lead to dehydration. When your blood sugar gets higher than 180 mg/dl, the kidneys work hard to expel the extra sugar along with water. This causes frequent urination, leading to dehydration.

How To Prevent Dehydration?

You can always prevent dehydration by following some simple tips: 

• Track Your Fluid Intake

Always track how much water you drink daily by using a water bottle with measurements or hydration apps to track your goal. Drink at least 8–10 glasses a day, which can help you adjust to heat, activity level, and health conditions.

• Limit Soda, Caffeinated Drinks, and Alcohol

These beverages increase fluid loss from the body. Always prioritise water, electrolyte-rich drinks, and herbal teas to maintain proper hydration without the ill effects.

• Monitor Your Pee

Your urine is one of the best ways to check hydration. If it's pale yellow, that usually means you are well-hydrated. On the other hand, having dark yellow or amber-coloured urine is a dehydration symptom. If your urine is dark or you are peeing frequently, it’s time to drink more fluids throughout the day.

• Follow Proper Hydration Strategies

Water may not be enough to prevent dehydration. You can also resort to drinking fluids with electrolytes, such as coconut water, sports drinks, or broth. In some cases, you can also try oral rehydration solutions (ORS) for further relief. This applies especially if you are doing daily activities like exercise or yoga.

2. How to check dehydration?

You can check for dehydration symptoms by observing certain signs like dry mouth, dark yellow urine, fatigue, dizziness, or reduced urination. Alternatively, look for fewer wet diapers and sunken soft spots in babies.

3. How to treat dehydration quickly?

You can drink fluids containing electrolytes, such as coconut water or sports drinks. Just drinking water will not help you consume the required minerals that can help keep your body hydrated.

The best prevention for dehydration is to drink fluids consistently throughout the day. You should ideally drink at least 6 to 8 glasses of water, rather than waiting until you feel thirsty. Do not forget to carry a water bottle, eat water-rich foods, and increase intake during exercise, hot weather, or illness.
