What Happens If You Drink Too Much Water

Drinking water is essential for maintaining health, an active lifestyle and hydration. However, excessive water intake can lead to overhydration, which can be severly harmful. Understanding the risks and symptoms of overhydration is crucial for maintaining a healthy balance.

 

What Happens If You Drink Too Much Water

What is Overhydration?

Overhydration occurs when the body takes in more water than it can expel, leading to an imbalance in electrolytes. This condition can cause the sodium levels in the blood to become dangerously low, a condition known as hyponatremia.

You can become overhydrated in a number of ways which we will discuss in this article. In all cases, overhydration can lead to water intoxication, also known as water poisoning. Your body’s water volume becomes far in excess of what your kidneys can readily process and excrete, which can cause the electrolytes in your body to be severely diluted and rendered inept.

When the amount of sodium (salt) becomes too diluted, you develop hyponatremia. This is the main concern of overhydration. When the sodium levels in your body are greatly reduced, fluids move inside your cells, leading to inflammation.


What is Water Intoxication?

Water intoxication, also known as water poisoning, happens when excessive water intake drastically dilutes sodium levels in the blood, causing hyponatremia. This can lead to severe and potentially life-threatening symptoms, including brain swelling, seizures, and, in extreme cases, death.


Is Being Overhydrated Bad?

Yes, being overhydrated can be very harmful to your health. It can disrupt the balance of electrolytes in your body, leading to various serious health issues. Understanding the causes and symptoms of overhydration can help you avoid this condition.

Is Overhydration bad?

Common Causes of Overhydration

Excessive Water Consumption

Drinking large amounts of water in a short period can overwhelm the kidneys, which are responsible for steadily excreting excess fluids. This can lead to overhydration.

Certain Medical Conditions

Conditions such as chronic kidney problems, heart failure, and liver disease can impair the body's proper functioning and ability to excrete fluids, increasing the risk of overhydration.

Use of Medications

Some medications, including antipsychotics and nonsteroidal anti-inflammatory drugs (NSAIDs), can affect the body's fluid balance and contribute to overhydration.

Psychological Factors

Conditions like psychogenic polydipsia (compulsive water drinking) can lead to excessive water intake and subsequent overhydration.


What are the Symptoms of Overhydration?

Recognizing the symptoms of overhydration is crucial for early intervention. Common symptoms include:

  • Nausea and Vomiting
  • Headache caused by excess pressure on the brain
  • Confusion, disorientation, or other adverse changes in your mental state
  • Seizures
  • Muscle Weakness and Cramps
  • Drowsiness

These symptoms result from the body's inability to maintain a proper electrolyte balance, particularly sodium.


How Overhydration Causes Electrolyte Imbalance

Overhydration dilutes the concentration and proper effectiveness of electrolytes in the body, particularly sodium. This imbalance can disrupt various bodily functions, leading to severe complications like brain swelling, seizures, and even death if not addressed promptly.


What are the Risks of Overhydration?

We listed some of the symptoms of overhydration above. However, it is important to understand that if not treated, those symptoms can become chronic and overhydration can manifest in the the following 3 detrimental ways:

Electrolyte Imbalance

The dilution of sodium and other essential electrolytes can lead to various health problems, including muscle cramps, weakness, and impaired nerve function.

Brain Swelling

Severe hyponatremia can cause the brain to swell, leading to increased intracranial pressure. This can result in headaches, confusion, seizures, and, in extreme cases, death.

Seizures and Severe Complications

Overhydration can cause seizures and other severe complications, especially if left untreated.


How to Fix Overhydration Immediately?

If you suspect overhydration, take the following steps:

  • Stop Drinking Water Temporarily: Give your body time to balance its fluid levels. Typically 4-6 hours
  • Eat Salty Snacks: Consuming salt can help increase and restore sodium levels in your blood.
  • Consume Electrolyte-Rich Beverages: Drinks like sports drinks or oral rehydration solutions can help replenish lost electrolytes, allowing you to rehydrate fast.
  • Rest and Avoid Further Physical Exertion: Resting helps your body recover and re-balance fluids.
  • Seek Medical Attention if Symptoms Are Severe: If you experience severe symptoms such as confusion or seizures, seek medical help immediately.
  • Monitor Urine Color for Normalization: Clear or light-colored urine typically indicates proper hydration.
  • Limit Fluid Intake Until Symptoms Subside: Reduce your water intake until you feel better and your symptoms resolve.

Safe Water Intake Guidelines to Stay Hydrated

Following safe water intake guidelines can help you stay hydrated without the risk of overhydration. Read this blog: “Recommended daily water intake: Daily Hydration Tips and Tricks”.

General Guidelines:

  • Listen to Your Body: Drink when you feel thirsty but not in excess of what your body can handle.
  • Consider Your Activity Level and Environment: Adjust your water intake based on your physical activity and current environmental conditions or climate.
  • Avoid Excessive Water Consumption: Stick to recommended water intake guidelines to avoid the risk of overhydration.

FAQs

Can you be overhydrated?

Yes, overhydration occurs when you drink more water than your kidneys can excrete, leading to a dangerous dilution of sodium in your blood.

What happens if you drink too much water too fast?

Drinking too much water too quickly can overwhelm your kidneys, leading to water intoxication and potentially severe health issues like hyponatremia.

What happens if you drink too much salt water?

Drinking too much salt water can lead to dehydration because the high salt content causes your body to lose more water than it takes in, worsening dehydration symptoms.

What happens if you drink too much carbonated water?

While carbonated water can contribute to hydration, excessive consumption can cause bloating and gas. However, it generally does not lead to overhydration.

Does hydration affect blood pressure?

Proper hydration helps maintain healthy blood pressure levels. However, both dehydration and overhydration can negatively impact blood pressure.


Conclusion

Maintaining a healthy balance of water intake is crucial for overall health. While staying hydrated is important, it's equally vital to avoid overhydration. Use these tips to manage your water consumption effectively and ensure you stay within safe hydration limits. Share these insights with friends and family to promote better hydration habits and prevent the risks associated with overhydration.
