In this situation the primary need is to remain hydrated and to keep electrolytes in balance. Providing him with a sports beverage of his choice will assist with electrolyte balance. Take a cup and put a mark at 8 ounces. He needs to drink 8-10 of those per day.
Caution with concurrent use of: NSAID (nonsteroidal anti-inflammatory drug) -
ibuprofen (Advil, Motrin),
naproxen (Aleve),
diclofenac,
indomethacin,
meloxicam. Elequis is a blood thinner generally not given to individuals over 80, but your doctor knows all this I am sure.
The
probiotic was a good move and most probiotics need refrigeration.
Some things that aggravate
diarrhea would include caffeine, sugar alcohols (substitutes).Gradually introducing psllium fiber (too much too soon will cause gas and abdominal discomfort), give dad lactaid or put lactaid pills in his milk jug to break down the lactose - a frequent cause of diarrhea these may help.
Let us know how he is in a couple of days. If no better or signs of getting worse, you may have to see the doctor before the weekend. Regards, Kathryn Shattler, MS,RDN
