Introduction
If you have IgA Nephropathy (IgAN), your doctor and healthcare team have likely encouraged you to drink more—or perhaps less—water. But how much is the right amount? And what if you don’t enjoy plain water? This article explores why hydration is essential, which foods and drinks count as fluids, and how to stay hydrated when water alone isn’t satisfying.
Why Is Hydration Important?
Our bodies consist of approximately 55–60% water. The fluids we consume help transport nutrients, regulate body temperature, remove waste via urine, lubricate joints, support brain function, and nourish our organs [1]. Our kidneys play a crucial role in balancing electrolytes in the blood while filtering excess nutrients and fluids.
For these reasons, your healthcare team may encourage you to drink enough water to maintain adequate hydration and prevent dehydration.
How Much Water Is Right for Me?
The best approach is to ask your doctor what amount is optimal for you. In the early stages of IgAN, staying well-hydrated is often recommended. Many doctors suggest drinking until your urine is pale yellow or clear. The exact amount of fluid you need depends on factors such as exercise, body composition, fiber intake, and climate.
A common starting point is 64 ounces (eight 8-ounce glasses) per day, with adjustments as needed. However, in later stages of kidney disease, a fluid restriction may be necessary, and it’s important to follow your healthcare provider’s guidance.
Signs and Symptoms of Fluid Overload
When your kidneys cannot filter all the fluids you consume, excess fluid may build up in your feet, hands, eyes, and midsection. This retention can lead to increased blood pressure, difficulty breathing, and even pneumonia [2].
What Counts as Fluids?
All foods and beverages that melt in your mouth contribute to your total fluid intake. Typically, only liquids are monitored for fluid restriction. However, if you are highly sensitive or consume large amounts of foods with high water content—such as watermelon—your doctor may recommend limiting these as well.
Fluids That Count Toward Hydration:
- Water
- Ice
- Tea
- Coffee
- Juice
- Smoothies
- Carbonated beverages
- Alcohol
- Ice cream
- Milk and drinkable yogurts
- Sorbet
- Pudding
- Soups, gravies, and sauces
Beyond Water: Hydration Alternatives
If plain water isn’t appealing, consider low-sugar alternatives. Many beverages—such as juice and soda—contain added sugars that contribute unnecessary calories. Instead, try:
- Sparkling water
- Sugar-free lemonades
- Frozen grapes
- Mocktails
If reaching your fluid goals feels overwhelming, a time-marked water bottle or fluid-tracking app may help.
