Potassium is an electrolyte that your body needs to function properly and is found in many foods, including coffee. The challenge when living with kidney disease is that your kidneys aren’t able to balance your potassium levels. Therefore, being mindful of how much potassium you consume is important to ensuring your potassium number isn’t too high or too low.

Factor coffee into your fluid allowance 

When living with kidney disease, what you drink and how much is important since your kidneys may not be able to filter as much extra fluid from your body. To manage your fluids, your doctor may ask you to limit your fluid intake. If this is the case, be mindful of your coffee consumption and don’t exceed your daily fluid allowance. You may need to limit or avoid drinking coffee if it’s causing excess fluid buildup. When kidneys fail, fluid intake becomes even more important to ensure dialysis can remove enough excess fluid during each treatment.
