What really happens if you drink too much water? Let's talk about Water Intoxication!

What really happens if you drink too much water? Let's talk about Water Intoxication!

Water is an essential part of our body. We drink a lot of water when we sweat, when we work out, and when we exercise. That's really good. But have you ever thought that if you drink too much water, that is, if you drink more water than your body can handle, that can also be a problem? Yes, it's true. Today we're going to talk about a potentially dangerous condition. This is called water intoxication.

What exactly is water intoxication?

Simply put, water intoxication is a condition that occurs when your body has more water than it needs. When this happens, you are unable to get rid of this excess water through sweating or urination.

Imagine, when we drink too much water, our blood becomes slightly diluted. Then the amount of sodium, a very important salt in the blood, decreases . We call this condition `(Hyponatremia)`. Due to this, water enters the body's cells and the cells start to swell. In particular, when our brain cells fill up with water like this, the pressure inside the brain increases and brain function is disrupted. This can cause changes in your consciousness, movements and behavior (`altered mental status`). It is also important to remember that this water intoxication can sometimes be life-threatening .

Normally, this is not an easy situation for someone with healthy kidneys. However, if you have a condition like kidney disease, or if you are an athlete who drinks a lot of water, it is good to be careful if you suddenly drink a lot of water when you are dehydrated. Drink water when you feel thirsty. Do not force yourself to drink water even after you are no longer thirsty.

Are there other names for water poisoning?

Yes, doctors use several other names for this condition. Some of them are:

  • Water Poisoning
  • Water Toxicity
  • Hyperhydration
  • Overhydration
  • Water Toxemia
  • Dilutional Hyponatremia
  • Water-Electrolyte Imbalance

Can you die if you drink too much water?

Yes, drinking too much water can actually be fatal, so this is not something to be taken lightly.

What are the symptoms of this? How do you recognize it?

Symptoms of water poisoning may not appear immediately. However, be aware of these things:

  • Nausea and vomiting: Feeling like your stomach is turning over, vomiting.
  • Bloating: Feeling like your stomach is bloated.
  • Headache: A severe headache may occur.
  • Drowsiness: Feeling sleepy all the time.
  • Muscle weakness, pain, or numbness: The limb may feel numb, achy, or suddenly stiff (jammed).
  • Changes in mental status:Confusion, irritability, dizziness.
  • Swelling (Edema): Swelling may be seen in the hands, feet, and abdomen.

Imagine a person participating in a long-distance race. He is sweating a lot, so he keeps drinking water for fear of dehydration. After a while, he starts to feel dizzy and has difficulty concentrating. If he shows these symptoms, it is possible that he has water poisoning.

How do I know if I'm drinking too much water?

It's not easy to know for sure. But the color of your urine can tell you a lot about your health. If you're drinking enough water, your urine should be a light yellow color, like straw or lemonade. If your urine is colorless and clear, like water, you may be drinking too much water.

If you have colorless urine and the symptoms mentioned above, stop drinking water immediately.

What can cause water poisoning?

If you drink too much water, you can get water poisoning. There are several situations where this is more likely to happen:

  • Exercise or sports: This risk is higher when drinking plenty of water to prevent dehydration, especially during sports that involve prolonged sweating, such as long-distance running, hiking, or cycling.
  • Working in extreme heat: When working outdoors in hot weather, or inside hot buildings (e.g. foundries).
  • Psychogenic Polydipsia: This is a mental health condition. It is commonly seen in people with illnesses such as schizophrenia . This condition causes the body to drink more water than it needs.
  • MDMA (ecstasy or molly) drug use: MDMA is a psychoactive stimulant. It can cause a high energy level, making you work hard, sweat a lot, and drink a lot of water to replace lost fluids.
  • Low body mass: Babies under one year old can easily become dehydrated. Their bodies are small, so they don't need a lot of water. They get the amount of water they need from breast milk or formula. But if you feel the need to give your baby water, don't give more than 3 ounces (about 90 ml). Also, be careful when taking your baby to swimming lessons, as they may accidentally swallow water.
  • Certain medications: Some antidepressants and antipsychotic medications can cause excessive thirst.

Additionally, water intoxication can also be caused by certain medical conditions that make it difficult for your kidneys to excrete excess water through urine. For example:

  • Chronic Kidney Disease
  • Liver Disease
  • Congestive Heart Failure
  • Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH)

Non-steroidal anti-inflammatory drugs (NSAIDs) can also increase water retention in your kidneys.

How much water do you need to drink to get to this point?

The amount of water that causes overhydration can vary from person to person. It's important to understand how your body uses water, so you can know how much is too much. Your body gets rid of excess water through urine. This can be roughly 32 to 64 ounces (1 to 2 liters) per day. For some people, drinking as little as a gallon (3 to 4 liters) of water within an hour or two can cause symptoms of water intoxication.

You can do these things to prevent dehydration:

  • Drink water when you feel thirsty.
  • Listen to your body.
  • Stop drinking water after your thirst is quenched; do not force yourself to drink.

What are the serious consequences of water poisoning?

If left untreated, symptoms of severe water intoxication can progress to conditions such as:

  • Seizures (seizures)
  • Delirium
  • Coma
  • Death

How do doctors diagnose this?

To determine if it is water poisoning, a doctor will first do the following:

  • Your medical history will be reviewed.
  • I'm asking about your symptoms .
  • A physical examination will be performed, especially looking for swelling in the arms, legs, and abdomen.
  • You may also have blood and urine tests to check your electrolyte levels .

What are the treatments for this?

The following are common treatments for water poisoning:

  • Stopping or limiting water intake.
  • Treat the cause of the water intoxication. This may include stopping certain medications.
  • Depending on the cause, you may also need to be given diuretics or intravenous fluids.

How quickly will I recover after treatment?

In most cases, you should start to feel better within a few hours after you stop drinking water.

What to expect if you get water poisoning?

With proper treatment, the chances of recovery from water poisoning are good. In mild cases, you will start to feel better within a few hours. In severe cases, it may take several days to recover.

Death from water poisoning is very rare.

Can water poisoning be prevented?

Not all causes of water intoxication can be prevented, especially some conditions that cause your kidneys to retain water. If you think you may be at risk, talk to a doctor.

But in general, take care of your body:

  • Drink water when you feel thirsty. But avoid drinking large amounts of water in a short period of time – drinking more than 32 ounces (about a liter) of water per hour is often too much.
  • Pay attention to the color of your urine. Your urine should be light yellow. Colorless, clear urine means you have more than enough water in your body.
  • Stop drinking water if you feel nauseous, bloated, or have a headache. These could be early signs that you've drunk too much water.

When you're sweating a lot, drinking moderate amounts of electrolyte drinks, 100% fruit juice, or orange water can also help prevent dehydration, as they help replace water and salts like sodium in your body.

When should you see a doctor?

If you or someone you know is showing symptoms of water poisoning, see a doctor as soon as possible. The sooner you seek treatment, the less likely it is that serious complications will develop.

What questions should you ask the doctor?

You can ask the doctor questions like:

  • How do you recognize water poisoning?
  • How severe is my water poisoning?
  • Can water poisoning be caused by drinks other than water?
  • How can we prevent water poisoning in the future?
  • Should I drink sports drinks? How much and how often?

How much water should you drink per day?

Your body is unique. The amount of water you need each day may be different from what others need. But in general, doctors recommend that adults drink this amount of fluid each day:

  • For men: 125 ounces (3.7 liters)
  • For women: 91 ounces (2.7 liters)

If you exercise a lot, or live in a hot climate or at high altitude, it's okay to drink more water than this average amount. But if you're unsure about how much water you should be drinking, talk to a doctor. He or she can tell you what amount is right for you.

Finally, things to remember (Take-Home Message)

Whether you're training for a marathon or spending the day working in the garden, staying hydrated is important. However, even if you're sweating a lot, the most important thing is to do everything in moderation.

Water is essential for life. But drinking too much can cause problems. Always listen to your body. Drink water when you feel thirsty. Pay attention to the color of your urine. If you sweat a lot, drink a sports drink or some fruit juice to replace the electrolytes you lose. If you have kidney problems, talk to your doctor about how much water you should drink. Stay healthy!

👩🏽‍⚕️ Additional questions (FAQs)

💬 Water intoxication means that people die from drinking water?

Yes! This is a surprising but harsh truth. Too much of anything is not good. This condition is scientifically called 'Hyponatremia'. If you drink a 'liter' of water continuously within an hour and a half, the kidneys will not be able to filter it as urine and the salt element (Sodium) in the blood of the whole body will be lost at once. Then the nerves and brain will stop working and the patient's life will be at risk.

💬 What happens to the brain when it loses salt (sodium)?

When the body has too much water and too little salt, the water that accumulates fills directly into the cells in the body, causing 'cellular swelling'. Swelling in other areas is fine, but when the 'brain cells' swell (cerebral edema), there is not enough room for the brain and it gets stuck in the skull! This causes the patient to have unbearable headaches, vomiting, and eventually seizures and coma.

💬 Who gets this in everyday life? How much water is safe to drink?

This condition rarely occurs in the average person! This is most common when 'marathon runners' drink gallons of water while sweating! Generally, do not drink more than 1 liter (3-4 glasses) of water per hour (that's the maximum your kidneys can filter). Also, when you sweat a lot, it is better to drink ORS or sports drinks (which contain sodium) rather than just drinking water!
