To prevent one of the worst results of nausea, be sure to stay hydrated. Thirst relief can be especially difficult when it’s hard to keep anything down. It’s even worse if your health symptoms include diarrhea. But even if you’re throwing up, some of the water you drink will be absorbed.
Dehydration can be mild or severe. Mild dehydration causes few problems, but in its severe form, dehydration can be life-threatening. Sometimes when a person begins to throw up dehydration comes on quickly.
Remember—water isn’t the only substance that can ease thirst. Tea—either hot tea or cold tea—can be a pleasant way to hydrate, and a decaffeinated choice is best. Sports drinks are good choices to, as is Pedialyte and similar drinks.
If you’ve just vomited, go slow. Start with a small amount of liquid—just a few tablespoons every few minutes to start. Slowly over time, increase the liquid as you’re able to hold it down.
If you’re worried about dehydration, ask yourself—are you urinating regularly? This is one of the clearest indications of whether or not you are getting enough to drink.
