Get him the Liquid IV and have him drink this , encourage him to drink more throughout the day like water ,Gatorade, any type of drink like this is good some have higher sugar then others

Thank you! Great suggestions. Yes I have thought of IV services.

Dehydration is hard, and a constant worry. We've had success with a combination of the below.

Sometimes one thing works for awhile, then another, or a combination - it's always an exhausting moving target.

1) More liquid in 'solid' foods: soup, cream of wheat, stews, drown every dish in delicious sauce with bread/rice to sop it up!, salads, pudding, ice cream, eggs, shaved ice with syrups, yogurt...

2) DrinkMate to carbonate anything.

3) 'Special treat' drinks - warm milk and honey with cognac or marsala, hot cocoa, teas, milkshakes, smoothies, iced tea, micheladas, virgin margaritas/daquiris?

4) Home IV saline rehydration. This is great if there's a service near you and your person is amenable. For our area, no Dr order needed, just a private service nurse comes in with a Liter saline bag, sets up the IV to drip in for the day and comes back to disconnect it in the evening. It's a fad for hang over cures and work-out buffs as well, so they have vitamin boosts etc. like B12.

5) Fruit! Melon, grapes, mango... We could absentmindedly eat a 3 cups of blueberries over day - mostly liquid.

I'm sorry you're going through this. I hope you both recover soon. So far we've managed to avoid Covid, but I understand that any stress can make PD worse.
