Do a normal person should have positive fluid balance or negative fluid balance?
A normal person should ideally have a neutral fluid balance, meaning the amount of fluid intake equals the amount of fluid output. Positive fluid balance (more intake than output) or negative fluid balance (more output than intake) can indicate underlying health issues and should be monitored carefully by healthcare professionals.
Negative fluid balance?
Patients in the hospital often have their I and O (Intake and Output) monitored. If a person puts out more fluid than is taken in that person is said to have a negative fluid balance. If the person takes in more than he puts out then he is said to have a positive fluid balance.
What effect would drinking water have on fluid handling in kidney?
Too much fluid intake will cause the kidneys to produce more urine and inadequate fluid intake will cause the kidneys to conserve body fluids by reducing the volume of urine excreted
What is the average urine input and output of a normal person daily?
It depends on the activity level and other factors. The "eight glasses of water a day" recommendation that everyone needs at least eight glasses of water a day is a myth. Fluid intake (including the moisture content of food) should equal the amount of liquid lost during the day, from perspiration, expiration and urination. During times of physical exertion or warm weather, people should take extra care in remaining hydrated. Elderly people sometimes have difficulty regulating their fluid consumption and should take additional care in making sure they remain hydrated during hot times, as they are also more frail and susceptible to heat stroke.
What if you are taking in one liter of fluid and your output is 2000 or more milliliters per day?
You become very dehydrated
Why more time urine comes?
Increased urine output can be caused by various factors, including increased fluid intake, consumption of diuretics (such as caffeine or certain medications), or underlying health conditions like diabetes or urinary tract infections. Additionally, hormonal changes can affect kidney function and urine production. Monitoring other symptoms is important to determine if a medical evaluation is necessary. If the increase in urine output is sudden or accompanied by other concerning symptoms, consulting a healthcare professional is advised.
Why is it important to have a daily fluid intake?
The human body is mostly water. As such, the majority of the body's fluids are composed primarily of water.
Why does your body make a lot of urine one day and very little the next?
The amount of urine your body produces can vary due to several factors, including fluid intake, dietary choices, physical activity, and hormonal changes. On days when you consume more fluids or foods with high water content, your body may produce more urine to eliminate the excess. Conversely, on days with lower fluid intake or higher levels of dehydration, urine output can decrease. Additionally, factors like stress or changes in temperature can also impact urine production.
How does antidiuretic hormone regulate fluid intake?
Antidiuretic hormone (ADH) regulates fluid intake by stimulating the kidneys to reabsorb water back into the bloodstream instead of excreting it in urine. This helps to maintain proper water balance in the body by increasing water retention. When the body detects dehydration or high salt concentration in the blood, ADH is released to prevent excessive fluid loss and increase thirst sensation to encourage more fluid intake.
In no more than one line, explain why when investigating the primary hypocalciuric hypercalcemia we measure the ratio of (Urine calcium/urine creatinin) not just urine calcium?
Measuring the ratio of urine calcium to urine creatinine corrects for differences in urine concentration due to variations in fluid intake and urinary output.
Why is fluid important between bones?
Synovial fluid is important between the bones because it helps reduce the friction between the bones. This fluid also lets a person move his joints more freely.
How does drinking more water usually help decrease fluid retention or edema when a patient has no fluid restrictions?
Many patients who have edema -- fluid retention -- often reduce their water and fluid intake. But this can compound the problem with edema. Fluid intake increases blood volume and stimulates the kidneys to remove fluid wastes. At the cellular level in tissues, increased fluid volume promotes better circulation, which prompts the cells to increase how they move wastes into the bloodstream for transport to the kidneys for processing.However, each patient must discuss this with their doctor. Some patients do have fluid restrictions depending on that patient's medical conditions. But generally speaking, most people can handle normal fluid intake when they have edema and often see better kidney function and less edema.
