Overhydration: Yes, It’s a Concern Too


Water is the primary component of the human body and helps to maintain bodily functions such as digestion, temperature regulation, and the removal of waste. However, too much water can be harmful. Overhydration, or drinking too much water, can lead to a condition called hyponatremia, which can be life-threatening.

In this blog post, we will discuss what happens when you drink too much water and how to prevent overhydration.

Types of Overhydration

There are two types of overhydration: 

1. Water Intoxication

When someone drinks too much water in a short amount of time, they become intoxicated by it. This can cause the sodium levels in the body to drop, leading to hyponatremia. The need for quick medical care in this case is urgent because this condition may be fatal.

2. Chronic Overhydration

Chronic overhydration occurs when a person consistently drinks more water than their body needs over a long period. This can cause the kidneys to become overworked and may lead to the development of other health conditions such as kidney disease.

Note: Drinking water is essential for maintaining good health. It helps to keep the body hydrated, regulate body temperature, and remove waste from the body. However, consuming too much water can be harmful.

How Much Water is Too Much?

The amount of water a person needs can vary depending on their age, sex, weight, and activity level. 8 cups of water per day is generally recommended. However, it is important to note that consuming too much water can be bad for your health.

The amount of water a person can safely drink depends on their circumstances, but a general guideline is to not drink more than one litre per hour. Drinking more than this can lead to water intoxication and hyponatremia. So, if you are wondering how much water is too much, it’s important to pay attention to your body’s signals of thirst and only drink as much water as you need to feel hydrated.

Disadvantages of Overhydration

If you are wondering what happens if you drink too much water, it can result in a number of health issues, such as:

  1. Hyponatremia: This condition occurs when the sodium levels in the body become too low, which may lead to seizures, coma, and even death.
  1. Overworked Kidneys: Consistently drinking more water than your body needs may put a strain on your kidneys, leading to kidney damage over time.
  1. Electrolyte Imbalance: Drinking too much water may dilute the levels of electrolytes in the body, including sodium, potassium, and magnesium. This may lead to muscle weakness, cramps, and irregular heartbeat.

Symptoms of Overhydration

Depending on the severity of the problem, overhydration symptoms can vary. Mild cases of overhydration may not have any noticeable symptoms, while severe cases can be life-threatening. Here are some common symptoms of drinking too much water:

  1. Nausea and vomiting
  2. Headache
  3. Confusion and disorientation
  4. Seizures
  5. Coma
  6. Muscle weakness
  7. Cramps
  8. Bloating and swelling
  9. Shortness of breath
  10. Tiredness

It’s crucial to get medical help right away if you develop any of these overhydration symptoms after consuming water.

Remedies for Overhydration

The treatment for overhydration will depend on the severity of the condition. Mild cases may be treated with simple lifestyle changes, while severe cases may require hospitalisation. Here are some common remedies for overhydration:

  • Decreasing fluid intake: If you are experiencing mild overhydration, your doctor may recommend decreasing your fluid intake to help balance your electrolyte levels.
  • Electrolyte replacement: If you have developed hyponatremia, your doctor may recommend an electrolyte replacement to help balance your sodium levels.
  • Diuretics: Diuretics are medications that help the body remove excess water. They can be used to treat severe cases of overhydration.
  • Hospitalisation: If you have developed severe hyponatremia, you may need to be hospitalised for treatment. In severe cases, treatment may involve the use of intravenous fluids and electrolytes to restore balance.

How to Prevent Overhydration?

The best way to prevent overhydration is to be mindful of your fluid intake. Here are some tips to keep you hydrated without going overboard:

  • Drink water in moderation: In addition to staying hydrated, it’s crucial to avoid overdoing it. Consider your body’s signals and drink water in moderation.
  • Pay attention to electrolytes: Electrolytes such as sodium, potassium, and magnesium are important for maintaining the body’s balance. Make sure to eat a balanced diet that includes foods rich in electrolytes.

Food to Eat to Reduce Overhydration

If you are experiencing overhydration, it is important to seek medical attention. However, some foods can help to replenish electrolytes and support your body’s recovery. The following foods could help to prevent overhydration:

  1. Bananas: Bananas are a good source of potassium, which is an important electrolyte that can become depleted with overhydration.
  1. Coconut water: Coconut water is a natural source of electrolytes, including potassium, sodium, and magnesium, making it a great option for replenishing fluids and electrolytes.
  1. Yoghurt: Yogurt is a good source of calcium, which can help to regulate electrolyte levels in the body. It also contains beneficial bacteria that can support digestion and nutrient absorption.
  1. Broth-based soups: Broth-based soups, such as chicken noodle soup or miso soup, can help to replenish fluids and electrolytes. The salt in the soup can also help to restore sodium levels in the body.
  1. Watermelon: Watermelon is a good source of water and electrolytes, including potassium and magnesium, which can help support hydration and electrolyte balance.

It is important to note that these foods alone cannot treat overhydration and medical attention is necessary in cases of severe overhydration.


While staying hydrated is important for good health, it is possible to overdo it. Drinking too much water can lead to overhydration and several health problems, including hyponatremia, overworked kidneys, electrolyte imbalances, and water intoxication. It is important to be mindful of your fluid intake and seek medical attention if you experience any symptoms of overhydration.
