Water Poisoning: All You Need To Know

We all know that water is crucial. In fact, every organism in our body needs water to survive.

Not only does water help our body to transfer oxygen and nutrients to the cells, control body temperature and assist metabolism, but also it flushes out the waste and the poison out of our body.

Sweating too much after intense activities, and you will start to feel dizzy. Three days without water, you are not going to be able to survive. Despite its importance, water intoxication is the real thing.

When we drink too much water, you are going to suffer from hyponatremia.

This article will thus walk you through the definition, causes, symptoms, diagnosis, treatments, and preventions of hyponatremia.

Myths About Drinking Water

We are commonly advised to drink about 8 glasses of water a day to stay hydrated. However, the truth is that this number is somehow arbitrary.

There has been no scientific evidence, research or study that support this advice. Listen to your body; you know what proper amount of water you have to drink every day.

Also, there are a lot of publications tell us that our body sometimes cannot tell the difference between hunger and thirst. So when you feel hungry, you need to drink. This advice is not entirely wrong, but it does not mean that you have to drink until you are full.

You are supposed to drink just a half or 1 glass of water when you feel hungry. And then, wait for about 10-15 minutes, if you still feel hungry, you definitely need to head for your meals.

Water Poisoning

What is Hyponatremia?

Hypo means underneath, beneath and low. Natr is the prefix for Sodium. Emia means blood. Altogether, Hyponatremia means low Sodium in the blood. An average Sodium level is 135-145 mEq/l. Thus, anything less than 135 mEq/l is hyponatremic.

Roles of Sodium / Causes of Hyponatremia

In order to understand all those causes, signs, and symptoms of hyponatremia, it is important to know how Sodium works in the human body.

Sodium is an essential electrolyte that helps regulate the water both inside and outside the cell. Water and Sodium love each other; water always wants to be where the Sodium is at.

Wherever Sodium is more congregated at, water will run to that place, and that’s what happening with hyponatremia.

Roles of Sodium

In hyponatremia, you have a low amount of Sodium outside the cell. Anything of a low concentration wants to move to a higher concentration.

As there is more sodium inside the cell, where water wants to be, all that water will rush into the cell, expand the cell and make the cell burst. This action affects cells everywhere in your body. One of the cells which are especially sensitive to this is brain cells.

And whenever they swell, you are going to have the most popular symptoms of hyponatremia – confusion.

Types of Hyponatremia and Their Consequences

Euvolemic Hyponatremia: This is when the water in the body increases but Sodium stays the same, which makes the Sodium becomes diluted.

You will suffer from the Syndrome of Antidiuretic Hormone. This hormone will be increased in secretion, and the body will start to retain water.

Other consequences can be diabetes insipidus, adrenal insufficiency, and Addison disease.

Hypovolemic Hyponatremia: It is a decrease in Sodium and a decrease in water. You become dehydrated as you have a loss of blood volume. Common symptoms of this are vomiting, diarrhea, NG suction, burn, and excessive sweating.

Hypervolemic Hyponatremia: This is when both water and Sodium increase, which leads to fluid volume overload. You are likely to have swellings on your body and suffer from congestive heart failure, kidney failure, excessive infusion of saline, and liver failure.
