The calculation of fluid balance involves measuring the amount of fluid entering the body and comparing it to the amount of fluid leaving the body. The purpose is to determine whether there is a deficit or an excess of fluid (Bannerman, 2018). Understanding a patient's fluid status can give an indication of overall health. Osmoregulation, the process of maintaining osmotic pressure, is how the body controls fluid and electrolyte concentrations. This is particularly important for patients who are unwell or have conditions that affect the kidneys. Maintenance of fluid balance is an important activity and is essential for optimal health. If a patient has too much or too little fluid, this imbalance can cause health problems. There are some pathophysiological conditions that can result in fluid overload, such as kidney disease and some types of heart disease. When overload occurs, the person finds it difficult to excrete excess water from the body, leading to oedema and serious health concerns. Dehydration occurs when the body is using more fluid than has been taken in or when there has been excessive fluid loss. The presence of oedema is a sign that fluid is in the wrong places. Patients who are oedematous may have fluid overload or be hypovolaemic.

What's included
Dehydration happens when your body loses more fluids than it takes in. Your body needs water for a variety of processes, including regulating your temperature, getting rid of wastes, and lubricating your joints. Staying hydrated is particularly important as you get older. An older adult who’s dehydrated may be at a higher risk for complications like:
Read on to learn more about why older adults are more prone to dehydration, the symptoms to look out for, and what you can do to help prevent dehydration. Older adults are more susceptible to dehydration for several reasons. Dehydration can have a variety of causes. Below are some of the most common causes of dehydration in older adults:
Treatment for dehydration involves replacing the fluids that have been lost. For mild to moderate dehydration, this includes drinking water or other fluids, such as juices or broths. Sometimes, vomiting or diarrhea can lead to a significant loss of electrolytes as well as water. In these situations, drinking beverages that contain electrolytes may be helpful. Examples include sports drinks and Pedialyte. If dehydration is more severe, hospitalization may be needed. In this situation, fluids and electrolytes will be given intravenously. If you’re an older adult, the following tips may help you stay well hydrated:
If you’re a caregiver for an older adult, you can do the following to help prevent dehydration:
Older adults are more susceptible to dehydration. There are many reasons for this, including lower fluid content in the body, decreased thirst response, and medications or underlying health conditions. Recognizing the symptoms of dehydration is important so you can work to replace lost fluids. Look out for symptoms like dry mouth, fatigue, dark-colored urine, and lightheadedness. Treating dehydration involves replacing lost fluids. You can work to prevent dehydration by making sure you regularly take in fluids throughout the day. This can include water, juices, broths, or foods with high water content. If you’re unsure of your hydration needs, talk to your doctor to find out how much water you should be drinking each day. Why are older patients at higher risk for fluid imbalances?The elderly have a reduced capacity to excrete a water load, which means they are predisposed to water overload and hyponatremia. Furthermore, various neuroendocrine changes in the elderly affect fluid and electrolyte homeostasis.
How does age affect body fluid?Total body water decreases with age. In a younger man near his ideal body weight, total body water composes 60% to 65% of his body mass. By age 80 years, this contribution is reduced to 50%.
Why are water and electrolytes essential during old age?They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help: Balance the amount of water in your body. Balance your body's acid/base (pH) level.
Why are older adults prone to dehydration EAQ?Main points: Older people are more susceptible to dehydration than younger people. This is partly due to lack of thirst sensation and changes in the water and sodium balance that naturally occur as people age.
