Drink lots of fluids
Fluids are critically important since you’re losing vital bodily fluids through sweating, vomiting, and diarrhea. If you are having trouble keeping liquids down, try taking small sips at regular intervals or chewing ice chips.
Try eating the BRAT diet
Keeping food down can be difficult with the stomach flu. Don’t force yourself to eat if the mere thought of food makes you cringe. When you do finally feel you can get something down, it’s best to start slow and simple.
Try acupressure to reduce nausea
Acupressure has been shown to be effective in treating some types of nausea. The Memorial Sloan-Kettering Cancer Center suggests finding pressure point P-6 by measuring the width of three fingers down from the bottom of your palm. Press below that width with your thumb and you’ll feel a sensitive spot between two tendons. Gently massage with your thumb for two or three minutes.
Get plenty of rest
When you have the stomach flu, your body needs rest in order to fight off the infection. Get plenty of sleep and reduce the amount of activity you normally do during the day. This means lounging on the couch when you’re not in bed. While you’re resting, your body is working hard to fight off the infection and repairing damage on the cellular level.
