However, when the kidneys are functioning normally, the body can handle wide variations in fluid intake. The body obtains water primarily by absorbing it from the digestive tract. Additionally, a small amount of water is produced when the body processes metabolizes certain nutrients.
The body loses water primarily by excreting it in urine from the kidneys. Depending on the body's needs, the kidneys may excrete less than a pint or up to several gallons about half a liter to over 10 liters of urine a day.
About 1½ pints a little less than a liter of water are lost daily when water evaporates from the skin and is breathed out by the lungs. Profuse sweating—which may be caused by vigorous exercise, hot weather, or a high body temperature—can dramatically increase the amount of water lost through evaporation.
Normally, little water is lost from the digestive tract. However, prolonged vomiting or severe diarrhea can result in the loss of a gallon or more a day. Usually, people can drink enough fluids to compensate for excess water loss.
However, people who have severe vomiting Nausea and Vomiting in Adults Nausea is an unpleasant feeling of needing to vomit. People also may feel dizziness, vague discomfort in the abdomen, and an unwillingness to eat. Vomiting is a forceful contraction of the stomach read more or diarrhea Diarrhea in Adults Diarrhea is an increase in the volume, wateriness, or frequency of bowel movements.

Mineral salts electrolytes Overview of Electrolytes More than half of a person's body weight is water. Doctors think about water in the body as being restricted to various spaces, called fluid compartments.
The three main compartments are Fluid read more , such as sodium and potassium, are dissolved in the water in the body. Water balance and electrolyte balance Electrolyte Balance are closely linked. The body works to keep the total amount of water and the levels of electrolytes in the blood constant.
For example, when the sodium level becomes too high, thirst develops, leading to an increased intake of fluids. In addition, vasopressin also called antidiuretic hormone , a hormone secreted by the pituitary gland a pea-sized gland at the base of the brain in response to dehydration, causes the kidneys to excrete less water.
The combined effect is an increased amount of water in the blood. As a result, sodium is diluted and the balance of sodium and water is restored. When the sodium level becomes too low, the kidneys excrete more water, which decreases the amount of water in the blood, again restoring the balance.
Thirst is one of the most important mechanisms to maintain water balance. When the body needs water, nerve centers deep within the brain are stimulated, resulting in the sensation of thirst. When the body has excess water, thirst is suppressed.
Certain populations are more prone to dehydration than others, including children , older adults, and people with certain medical conditions like diabetes and kidney disease. The signs and symptoms of dehydration include:.
Urine color is also a common indicator of hydration status. Generally, the paler the color, the better hydrated you are. That said, the color can change for reasons other than your hydration status, including diet, certain medications, and some medical conditions.
Are you dehydrated? Your pee color can give you a clue. Water is the best option for rehydrating your body, but oral rehydration solutions also provide essential electrolytes. These may be useful if you are dehydrated due to diarrhea or vomiting, or if you have been exercising intensely.
Severe dehydration may need medical treatment, where a doctor provides fluid intravenously. When you drink water, your body starts absorbing it after 5 minutes, and peak absorption can take 15—60 minutes, according to a study.
This will depend on several factors, such as how much fluid you take in, what type of fluid, how dehydrated you were to start with, and whether the cause of dehydration, such as diarrhea, has gone away.
How long does it take for water to go through your body? Water is effective, but oral rehydration solutions can also help relieve dehydration if you have a hangover. Being hydrated can help you sleep better, but it can also mean you need to pee more during the night.
Tips for nighttime hydration include:. Dehydration occurs when your body loses more fluids than it takes in. For most people, drinking water is the best way to stay hydrated and rehydrate. Severe dehydration is a life threatening emergency and needs urgent medical attention.

Sometimes, your electrolyte level may be too low, which means certain body functions suffer. Generally, you receive electrolytes through the foods and beverages you consume, just like with hydration. Sodium is one example of an electrolyte.
This is one of the electrolytes that maintain a fluid balance in your cells. Both your nerves and muscles require sodium as well.
In addition, sodium is a necessary electrolyte for maintaining a normal blood pressure level. Calcium is another necessary electrolyte. Your body needs it for muscle contractions.
Your body uses the electrolyte potassium to balance your electrolyte levels and for nerve function. Additionally, your body needs chloride to function.
Your body uses this electrolyte for digestion, too. It also plays a role in balancing your pH level. Your body has an internal pH balance level, which is how alkaline or acidic your body is. Your blood, for instance, is usually more basic than acidic.
This electrolyte helps maintain this balance. However, nausea, fluid retention, and lethargy are common with any electrolyte imbalance. Since your body needs potassium for your heart to function, a deficiency could lead to an abnormal heart rhythm.
Your body requires it to balance the hydration in your cells. You may struggle to breathe or experience diarrhea, vomiting, weakness, or fatigue. Muscle cramps and twitches can occur, and so can fatigue and muscle weakness. It may even trigger high blood pressure and an abnormal heart rhythm.
Not receiving enough sodium can cause an array of health problems. For instance, you may feel drowsy or lack energy. You might become restless or irritable. Muscle spasms, cramps, and weakness can occur as well.
You might also notice that you have a headache. In extreme cases, a sodium deficiency can lead to coma or seizures. Although you require electrolytes to maintain hydration , you require enough water for your body to function as well.
Water serves the purpose of transporting nutrients to your cells. Your body requires it to send oxygen to your brain.

Electrolytes are minerals that have an electric charge when they are dissolved in water or body fluids, including blood. The electric charge can be positive or negative. You have electrolytes in your blood, urine pee , tissues, and other body fluids.
An electrolyte imbalance means that the level of one or more electrolytes in your body is too low or too high. It can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water dehydration or too much water overhydration.
Some of the more common reasons why you might have an imbalance of the water in your body include:. A test called an electrolyte panel can check the levels of your body's main electrolytes.
A related test, the anion gap blood test , checks whether your electrolytes are out of balance or if your blood is too acidic or not acidic enough. The treatment for an electrolyte imbalance depends on which electrolytes are out of balance, if there is too little or too many, and what is causing the imbalance.
In minor cases, you may just need to make some changes to your diet. In other cases, you may need other treatments. For example:.
