signs and symptoms of severe dehydration

Ensuring You Always Stay Hydrated

Imagine this: you've been hiking in the Grand Canyon under the relentless midday sun. Your water bottle ran dry hours ago, and every step feels heavier than the last. Suddenly, your skin feels parched and as dry as the desert sand beneath your boots.

Your mouth is sticky, and your tongue feels like an old piece of leather. You notice your hollow, sunken eyes when you reflect on your phone screen. These are the alarming dehydration symptoms starting to manifest. And according to a study, 75 percent of Americans suffer from chronic dehydration.

So, let’s take a closer look at the signs and symptoms of severe dehydration and find ways to combat it.

Causes of Dehydration

Dehydration can be caused by many factors, such as sweating too much in hot weather or during physical activity, not drinking enough fluids or having a fever. Certain medications can also cause dehydration, such as diuretics.

Additionally, certain medical conditions, such as diabetes and kidney disease, can increase your risk of dehydration. It's highly advisable to stay hydrated to maintain good health, especially during the summer when the heat can cause us to lose more fluids than we take in.

The Role of Water in the Body

Water is essential for our bodies to function correctly. It involves many processes, including digestion, absorption, and circulation. It also helps regulate body temperature and remove waste.

Our bodies are 60% water, and our brains and hearts are even higher in water content. When we become dehydrated, it can affect our concentration, coordination, and overall physical performance. Drinking enough water is vital to maintaining a balance of fluids and electrolytes.

Mild vs. Severe Dehydration

Mild dehydration can be remedied by drinking fluids like water or electrolyte drinks. Symptoms of mild dehydration include thirst, dry mouth, headache, and dark yellow urine.

However, severe dehydration can be life-threatening and may require medical attention. Even a mere 3-4% dehydration levels can cause up to 50% reduction in work productivity.

Symptoms of severe dehydration include extreme thirst, dry skin, rapid heartbeat, rapid breathing, and confusion. If you suspect you or someone else may be severely dehydrated, seek medical attention immediately.

Signs and Symptoms of Severe Dehydration

1. Feeling Unusually Tired or Confused

You're tired, but you can't seem to fall asleep. You need clarification or a reminder like you're walking through a mental fog. And to top it all off, you're constantly feeling thirsty, but no amount of water quenches your thirst.

These could be signs that you're dehydrated. It's easy to overlook, especially if you're not used to drinking much water due to work or school.

2. Dizziness When Standing Up

Do you ever feel lightheaded or dizzy when you stand up too quickly? It can be alarming and leave you feeling unsteady on your feet.

Did you know this sensation could be a sign that you're dehydrated? When we're not drinking enough water, our bodies can't maintain the right balance of fluids. This can cause a drop in blood pressure, making us feel dizzy and disoriented.

3. Not Passing Urine for Eight Hours

Have you ever found yourself so distracted by work or other pressing tasks that you realize you haven't passed urine in hours? While it may seem like a minor inconvenience, not passing urine for eight hours or more can indicate dehydration.

When your body doesn't have enough fluids, it holds on to what it does have, resulting in decreased urine production. This can cause a buildup of toxins and waste in your body, leading to further complications.

4. A Weak Pulse

Dehydration affects your heart rate because there's less fluid in your bloodstream. It could indicate dehydration if your pulse is weak or thready. If you're already dealing with a pre-existing medical condition like heart disease, this symptom can be particularly concerning, and you should seek medical attention.

5. A Rapid Pulse

On the other hand, if you're dehydrated, your heart may pump faster than usual to compensate for the decrease in fluid volume. If you feel your heart racing and it doesn't slow down after a few minutes, it could indicate severe dehydration. If this symptom is accompanied by any others, like confusion or dizziness, seek medical attention immediately.

How to Effectively Treat Severe Dehydration

Let’s discuss effective methods of treating severe dehydration.

1. Rehydration Techniques for Severe Dehydration:

One of the most effective ways to tackle dehydration is through rehydration techniques. These techniques involve replenishing fluids, electrolytes, and minerals to restore normal body function. IV fluids may be administered for severe dehydration to address the situation quickly.

Additionally, oral rehydration solutions (ORS) can be used as a preventive measure or for mild dehydration. Hydrating foods and beverages such as fruits, vegetables, and sports drinks can also help combat dehydration. It is crucial to take dehydration seriously and take action quickly to avoid health complications.

2. Addressing Electrolyte Imbalances:

Electrolytes - think sodium, potassium, and magnesium - are the unsung heroes behind your body's everyday functions like muscle movement and nerve signaling. Their balance can tip during severe dehydration, potentially triggering serious issues like seizures or irregular heartbeats.

Keeping an eye on these levels is vital in handling dehydration. A quick, tasty fix? Sip on an electrolyte-rich drink. From the sports-inspired zing of Gatorade and Powerade to the tropical freshness of coconut water, these options can help you top up those crucial elements. Can't consume them orally? Don't worry; your doctor might suggest an IV infusion packed with electrolytes.

3. Gradual Reintroduction of Fluids and Monitoring:

Imagine your body as a dried-out sponge. Like this sponge, your body needs to absorb water gradually to rehydrate properly. Hence, you introduce fluids slowly, perhaps sipping on rehydration salts or electrolyte-filled drinks.

Keep a keen eye on your symptoms and your body's response. Just like a careful gardener nourishing a wilted plant back to life, pay attention to every signal your body sends. If you pace yourself and monitor your intake and reactions, you'll eventually restore your body's balance, helping the desert bloom into an oasis.


Severe dehydration can be a scary experience, but prompt action is critical to effective treatment. Whether it's utilizing oral rehydration solutions, addressing electrolyte imbalances, or gradually reintroducing fluids, the most important thing is to start the treatment process as soon as possible.

Don't forget to prevent future episodes of dehydration by staying hydrated throughout the day. Don't hesitate to seek medical attention if you're in doubt or your symptoms worsen. With proper treatment, you can overcome severe dehydration and prevent future complications.
