Parkinson's and Hydration

Summer has come in with a roar here in Tucson and for many of our PWR! family. With summer heat and humidity (or dryness, if you live here in Arizona) comes dehydration. Unfortunately, people with Parkinson disease are more likely to get dehydrated to begin with, and it may cause some serious symptoms.

Read below for some tips to improve your hydration and keep your body working like a well-oiled machine.

Drinking fluids might be a little bit harder if you have PD. Why?

  • Your medications can make you more dehydrated. Try to time it so that you drink water when you take your medication each day.
  • People with Parkinson disease may experience constipation, which is when it is difficult to pass bowel movements. Drinking water or eating foods with high water content can help to reduce constipation.
  • You might have difficulty swallowing, drooling (sialorrhea), or more sweating when you have PD. Talk to you neurologist or speech therapists about options to control some of these symptoms, so that you aren’t losing as many fluids.
  • You may lose the drive to drink, so you may not feel thirsty when you are already beginning to get dehydrated.

That’s why it’s SO important to keep on top of hydration!!

According to the Mayo Clinic, signs of dehydration in an adult include:

  • Extreme thirst
  • Less frequent urination
  • Dark-colored urine
  • Fatigue
  • Dizziness
  • Confusion

If it is hard to get 8 or more glasses of water in per day, consider the following tips to increase how much water you take in:

  • Consider alternative ways to get fluids. You may try using a water filter (filled with fruit or herbs), eating high-water fruits (like watermelon and kiwi), drinking electrolyte replacement drinks (like Liquid IV), or mixing a bit of lemon or orange juice to make your fluids more appealing. You can also try other drinks, but avoid drinks that have a lot of caffeine or alcohol, as they may dehydrate you.
  • Set a timer to remind you to drink water.
  • Time your water drinking to when you take your medication.
  • Get a water bottle that is easy to carry, so that you don’t lose your drink in the house while life gets busy. Consider using a water bottle with a strap, like this, or perhaps a backpack, like this so that you can keep your hands free.
  • When you exercise, plan to drink before you exercise, so that you don’t enter a deficiency early.

As you drink more fluids, your brain will be clearer, and you may have more energy. Happy hydrating!
