Causes of dehydration and how to treat it

The body loses water and fluids regularly through natural processes like sweating and peeing. But if you don't replace those fluids, you can get a condition called dehydration.

Dehydration happens when the body loses more fluids than it takes in. That’s why the Mayo Clinic advises women to drink about 12 cups of fluids each day.

In this article, we'll look at what causes dehydration, how to diagnose it, how to treat it, and ways to prevent it.

Causes of dehydration

Dehydration can happen from any cause that makes the body lose more fluids than it gets. Some conditions can cause this to happen, They include:

1. Sweating

Sweating is a natural way the body cools itself. When body temperature rises above normal, sweat glands activate to release moisture and cool down.

This works by evaporation. When a sweat drop evaporates from the skin, it takes some heat with it. The more sweat produced, the more evaporation and cooling.

Sweating also helps keep your body's electrolytes balanced since sweat contains water and salt.

Too much sweating can cause dehydration because the body loses a lot of fluids. This is called hyperhidrosis or excessive sweating.

2. Diseases

Some illnesses cause constant vomiting and diarrhea. Both make the body lose a lot of water, fluids, and electrolytes.

Electrolytes are minerals that control muscles, blood chemistry, and organ functions. They are found in blood, urine, and other body fluids.

Vomiting and diarrhea can weaken the body by causing big fluid and electrolyte losses, which may lead to dehydration and serious issues like strokes and coma.

3. Fever

When the body has a fever, it loses fluids through the skin to try to lower the temperature. So, fever often causes excessive sweating.

If the lost fluids from fever aren't replaced, dehydration can happen.

4. Urination

Urination is a natural way the body gets rid of toxins. But chemical imbalances can increase urine production, which makes the body lose more fluids and can lead to dehydration.

Symptoms of Dehydration

Dehydration symptoms vary with how severe it is, from mild to severe. These signs can start before full dehydration sets in.

Mild to moderate dehydration symptoms can include:-

• Tiredness.

• Dry mouth.

• Dry skin.

• Feeling more thirsty.

• Less tear production.

• Less frequent peeing.

• Constipation.

• Dizziness.

• Headache.

Severe dehydration symptoms may include:-

• All mild to moderate dehydration symptoms.

• Extreme thirst.

• Less sweating.

• Dark urine.

• Low blood pressure.

• Rapid breathing.

• Sunken eyes.

• Pale skin.

Severe dehydration is a medical emergency that needs urgent medical care if symptoms appear.

Also, kids and elderly should get immediate treatment if they feel any dehydration symptoms, even mild or moderate.

Besides that, some cases need emergency care too. Symptoms include:-

• Severe diarrhea.

• Diarrhea lasting 3 days or more.

• Blood in stool.

• Not being able to hold fluids.

• Constipation.

How to diagnose dehydration

A doctor can diagnose dehydration by checking the patient's symptoms and ruling out other conditions. Then they take the patient's medical history and check vital signs like heart rate and blood pressure. A fast heart rate and low blood pressure can point to dehydration.

The doctor might do a blood test to check electrolyte levels, which can show fluid loss. They also check creatinine levels to see how well the kidneys work, which helps indicate how serious the dehydration is.

Also, the doctor may use a urine test, which is a urine sample to check for bacteria and electrolyte loss. The urine color along with some symptoms can also indicate dehydration.

How to treat dehydration

Treatment can include rehydration, replacing electrolytes, and treating the causes of dehydration like vomiting and diarrhea.

1. Rehydration

Rehydration might not work for all cases, like people with severe diarrhea or vomiting. In those cases, fluids can be given through a vein.

For that, a small tube is put into a vein in the arm. This usually helps return water and electrolytes to the body.

For those who can drink without throwing up, they may be told to drink water with a rehydration drink that has electrolytes, like low-sugar sports drinks. Kids with dehydration often get recommended Pedialyte.

Also, if no rehydration solution is available, you can make it at home by following these steps:-

• ½ teaspoon of salt.
• 6 teaspoons of sugar.
• 1 liter of water.

You have to make sure to use accurate measurements because using too much salt or sugar can be dangerous.

Also, avoid soda, alcohol, sugary drinks, and caffeinated drinks since these can make dehydration worse.

Complications of untreated dehydration

You should never leave dehydration untreated, even if it seems minor, because it can cause life-threatening complications, andThese include:-

• Heat exhaustion.

• Heat cramps.

• Heat strokes.

• Loss of electrolytes.

• Decreased blood volume.

• Kidney failure.

• Coma.

How to prevent dehydration

There are some ways to prevent dehydration, including:-

• When sick, you should drink more fluids, especially if vomiting or diarrhea.

• When exercising, you should drink water before, during, and after your workout. Also, make sure to take electrolytes after exercising.

• Wear light and cool clothes in hot months, and avoid direct sun exposure.

• You should get the recommended amount of water and fluids daily.

In the end, dehydration happens when you don't get enough fluids, whether due to weather or illness. Dehydration can get serious really fast.
