Yes, it is possible to drink too much water. Water is important for the body, especially when you are pregnant or breastfeeding, but very large amounts in a short time can disrupt the body's salt balance. Fortunately, for most people, this doesn't happen with normal thirst and typical drinking habits. The most important thing is to listen calmly to your body rather than forcing fluids down because you think you need to reach a certain number of liters.

What happens if you drink too much water?

Normally, the kidneys help the body regulate fluid balance. But if you drink very large amounts of water quickly, the sodium content of your blood can become diluted. This is called hyponatremia and means that the salt balance in the body becomes disrupted.

This is especially relevant if you drink a lot during prolonged physical activity, with heavy sweating, vomiting or diarrhea, or if you have a disease or are taking medication that affects fluid and salt balance. So it's not water itself that's the problem, but the amount, the speed, and the body's overall situation.

What are the signs of too much water?

Milder symptoms can resemble many other things, and therefore they can be difficult to interpret on their own. If you feel unwell, do not try to solve it by simply drinking even more water.

• Headache
• Nausea or vomiting
• Restlessness, dizziness, or unusual fatigue
• Confusion or difficulty concentrating
• Bloating or a feeling of being very full of fluid

 

Seek urgent help if you or someone else experiences severe confusion, seizures, fainting, pronounced lethargy, or difficulty breathing. These can be signs of a serious imbalance that needs immediate assessment.

How much water should you drink a day?

There isn't one correct number of glasses or liters that suits everyone. Your needs depend, among other things, on your body size, what you eat, whether you are physically active, and whether you sweat, have a fever, or lose fluid in other ways.

For most people, thirst is a good and natural guide. The color of your urine can also give a small indication: Light yellow urine is often a sign that you are getting adequate fluid, while completely clear urine all day can be a sign that you are drinking more than you need. Dark urine, conversely, can be a sign that you need more fluid, but can also be affected by, for example, vitamins and food.

Is the need for water greater when pregnant?

When you are pregnant, your body is working overtime, and you may experience more thirst than usual. This is completely natural. At the same time, nausea, vomiting, frequent toilet visits, or a warm feeling in the body can make it harder to find a rhythm that feels good.

However, you don't need to force large amounts of water down. Keep it simple and gentle:

• Keep water close to you, so it's easy to take small sips throughout the day.
• Drink little and often if you feel nauseous or full quickly.
• Eat regularly and varied, so your body also gets the salts and nutrients it needs.
• Talk to your midwife or doctor if you are vomiting a lot, cannot keep fluids down, or are concerned about your fluid balance.

 

If you have swelling in your hands, feet, or legs, it is rarely a sign that you should just drink less. Swelling during pregnancy can have several causes and should always be seen in conjunction with how you feel otherwise. Contact your midwife or doctor if the swelling comes on suddenly or along with, for example, headache, visual disturbances, or pain in the upper abdomen.

Should you drink extra water when breastfeeding?

Breastfeeding can make you thirsty, and it's a good idea to have a glass or bottle of water at hand when you sit down with your baby. But you don't need to drink more than you want to in order to breastfeed. The body is good at regulating itself, and it is usually enough to drink when you are thirsty and eat a normal and varied diet.

The first few weeks with a newborn can be intense, and it's easy to forget your own needs. A small glass of water at your regular nursing spot can be a loving reminder to also take care of yourself.

When should you talk to a professional?

Contact a doctor, midwife, or out-of-hours doctor if you are pregnant or have just given birth and continue to be very thirsty, urinate unusually much, cannot keep fluids down, or feel unwell. This also applies if you have a known heart, liver, or kidney disease, take diuretics, or have previously had problems with your salt balance.

My dear, you should not measure, control, and worry about every glass. Small sips, regular meals, and attention to your body's signals are for most people both a safe and sufficient path.

Frequently asked questions

Can you get water intoxication from drinking too much water?

Yes. Very large amounts of water in a short time can dilute the salt in the blood. It is rare, but can be serious and requires prompt assessment if symptoms are clear.

Is it dangerous to drink a lot of water at once?

It can be unfortunate to drink very large quantities in a short time. It is better to distribute your fluid intake throughout the day and drink according to thirst, unless you have been advised otherwise by a healthcare professional.

Is it normal to be very thirsty during pregnancy?

Yes, many people experience increased thirst during pregnancy. If the thirst is very severe, persistent, or accompanied by discomfort, you should talk to your midwife or doctor.

Do I need to drink more water to produce enough milk?

No, you don't need to force extra water down to produce milk. Drink when you are thirsty, and preferably have water next to you while breastfeeding.
