Kidney Korner: Fluid Intake

We Don't Just Mean Water

Fluid intake is a complicated topic as each patient has unique and individual needs. This can change overtime due to medication changes, new diagnoses, or lifestyle changes. When we talk about fluids, we do not mean just water. It is important to be aware of the amount of fluids you intake daily from a variety of sources and how that may impact your health and hydration. There are foods with higher water contents that may impact your hydration depending on the amount consumed on a regular basis. These are called insensible fluids. It is advised that we be aware of what they are, but are often not included in the total fluid intake. 

Common Fluids Beyond Water

Munjal’s Musings:
Eight 8oz (64oz) cups of water a day does not apply to everyone. Each person requires different fluid intake daily based on unique and individual needs. Those with sedentary lifestyles, like office staff, do not require as much fluid as those exerting themselves, like construction workers.
A fluid can be easily classified as something that you put in a cup. However, many foods have high water contents, making that an additional source of fluid, called insensible fluids. However, for simplicity, focus on the actual fluid that you drink, not the water content in foods.
