Kidney Korner: Fluid Intake Part 2

How Much is Too Much?

In our last segment of the Kidney Korner, we discussed what fluids are and foods that have high water content, or insensible fluids (read about it here). This month, we are discussing hydration and how much fluid is too much for the kidneys to handle. 

If you drink too much fluid, your kidneys may not be able to process and filter it properly (especially if you have kidney diseases) causing a myriad of problems. Decreased kidney function, Congestive Heart Failure (CHF), edema, liver diseases, and muscular issues have been linked to fluid retention. It is extremely important to maintain the balance of fluids and electrolytes in your body to stay healthy. Symptoms of overhydration can include swelling, increased trips to the bathroom (see the exceptions below), and clear, colorless urine (looks like water). 

There are many exceptions and special circumstances to consider when it comes to fluid intake.
  • Dialysis: People who are on dialysis have strict fluid restrictions to adhere to. Since their kidneys no longer function as they should, most patients retain the fluid they consume making it dangerous to consume too much. Their general fluid recommendation is 32 oz per day.
  • Medications: There are numerous medications that can affect fluid retention. 
    • Diuretics, or water pills, help your body release the fluid it may be retaining. 
    • Diabetes and some diabetes medications will also affect fluid levels due to blood sugar regulation. These medications work to spill excess sugar through urination. Many patients see an increase in their trips to the bathroom while taking these. 
  • Season/Weather: It is normal to increase fluid intake as the seasons change. We tend to drink more in the summer than we do in the winter to account for the fluid lost when sweating. 
  • Occupation: Those who work jobs outside in the elements or more strenuous jobs tend to sweat more, increasing their fluid requirements compared to those who may work office jobs and don’t sweat. 

Munjal’s Musings:
How often do you water your plants? It can be complicated. You have to ask a few questions: 
  • How big is the plant? 
  • Are they inside or outside?
  • What kind of soil are they planted in?
  • What type of watering requirements does that plant species have? 
Under watering plants can be just as dangerous as over watering them as well.
The same goes for people. Size, health status, medications, occupation, location, and the season are just a few of the elements that go into determining proper fluid intake for a person. 

You can also view hydration like filling a bucket. You want the bucket to be nicely topped off, not overflowing or only half full. It is a balancing act. 

It is important to have routine lab work done regularly and discuss your individual needs with your doctor(s). There is no universal guideline for the amount of fluids a person should consume daily. 

Tune in next week as we continue our segment on fluids and discuss the symptoms of dehydration and when to seek help.
