How Do You Know If You're Dehydrated?

Dehydration rarely occurs suddenly. Sometimes, your body will give you signs you need to be aware of. Being very thirsty is the most noticeable. But there are other indicators to watch out for as well. Here are a few:

Causes of Dehydration

Dehydration can occasionally happen for simple causes like not getting enough water. But symptoms of dehydration might be triggered by other, more severe factors. These are as follows:

  • Extreme fluid loss, including the loss of water and electrolytes, can happen quickly due to the sudden emergence of severe and acute diarrhea. Additional fluid and mineral loss results if you are also vomiting, on top of the various issues described. Dehydration is an inevitable outcome of this.
  • Dehydration often goes hand in hand with a high fever. Along with fever, dehydration might worsen if you vomit and suffer from diarrhea.
  • Another way the body loses water and expels toxins is through sweating. You risk getting dehydrated if you sweat excessively before consuming enough water to replenish the lost fluid. When it's hot and humid outside, this happens faster.
  • Uncontrolled or undiagnosed diabetes may lead to an increase in the frequency of urination. This results in a loss of more fluids than the body should eject. Certain medications, like those used to control blood pressure, also heighten the frequency of urination, resulting in dehydration.

How Much Water Should We Drink Every Day To Stay Hydrated

The amount of fluid you require each day may vary according to your gender, level of exercise, fitness level, weather, and any underlying medical issues. The general recommendation is to drink around half of your body weight in ounces (in pounds). For comparison, a 200-pound adult needs 100 ounces of water each day. Your requirement for water will depend on how active you are, as was already indicated. As a result, you should increase your regular water intake by about 12 ounces for every 30 minutes of exercise. If an average healthy person needs to use the restroom every two to four hours and their urine is light yellow, they drink enough.

Dehydration in Pregnancy

For a healthy pregnancy, pregnant women must drink enough water. Pregnant women need extra fluids to stay hydrated, and illnesses like morning sickness can worsen the problem. Dehydration that is too severe might cause heart palpitations, lightheadedness, fainting, decreased amniotic fluid levels, and a higher chance of experiencing Braxton-Hicks contractions.

Pregnancy And Water Intake

The recommended daily fluid intake is three liters (eight to twelve glasses). Rather than consuming a lot of water at once, try sipping it throughout the day. For every hour of light exercise you do, add another glass of water. To make up for the fluid that loses from sweat in the summer, you will need to consume even more liquids. Don't let your fear of retaining water stop you from drinking water and other fluids.
Interestingly, not drinking enough can lead to fluid retention as your body will retain more fluid if it detects that it is getting dehydrated. The color of your urine is the most significant indicator of whether you are thirsty, and it ought to be colorless or light yellow. You should drink more water if your urine is dark. Call your doctor if you have dizziness that doesn't go away and have decreased urination despite drinking water.

Additionally, it's essential to stay hydrated; therefore, it's advised to drink lots of water and other non-alcoholic, caffeine-free beverages.

Pinching the skin on the top or back of your hand can quickly check whether you should drink more water. You are less likely to dehydrate if your skin returns to a quick, smooth position. If your skin slowly goes back flat to your hand and leaves a crease for a few seconds, it's probably time to find some water.

How To Prevent Ourselves From Getting Dehydrated?

  • Reduce your alcohol intake since it makes it harder to detect the early indications of dehydration.
  • Infants and older kids need to consume enough water for proper fluid maintenance. When your child first exhibits sickness symptoms, you should give them more water or an oral rehydration solution. Dehydration should not be delayed.

What drinks, besides water, are a good source of hydration?
