Do not eat or drink anything for several hours after vomiting. Sip small amounts of water or suck ice chips every 15 minutes for 3-4 hours. Next, sip clear liquids every 15 minutes for 3-4 hours. Examples include water, sports drinks, flat soda, clear broth, gelatin, flavored ice, popsicles or apple juice.
Resting propped up in a seated position with the head elevated at least twelve inches above the feet is ideal. Remain in this seated rested position for a minimum of an hour, or until you are no longer experiencing nausea. Do not lie down all the way. Resting in a fully flat position could trigger vomiting.
Diarrhoea and vomiting can spread easily
Stay off school or work until you've not been sick or had diarrhoea for at least 2 days. If you also have a high temperature or do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better.
Drink lots of fluids if possible, but start slowly with 1–2 sips every 5 minutes. If you become nauseated, wait 20–30 minutes and then begin again.
If you think you can keep down fluids, start with small amounts of water. After you stop vomiting and feel stable, begin by consuming 1 teaspoon of cool water every 10 minutes and gradually increase to 1 tablespoon every half hour.
Take measures to dispose of and/or clean and disinfect the tools and equipment used to clean up the vomit and/or fecal matter. PROPERLY WASH YOUR HANDS - AND IF POSSIBLE TAKE A SHOWER AND CHANGE YOUR CLOTHES. Discard any food that may have been exposed in the affected area.
A person with gastroenteritis is most infectious from when their symptoms start until 48 hours after all their symptoms have passed, although they may also be infectious for a short time before and after this.
Sleep helps the stomach finish digesting any food in it. It may calm your child's vomiting.
While it might seem tempting to brush your teeth immediately after vomiting, we don't recommend it. That's because throwing up leaves stomach acid in your mouth, and when you brush immediately after, you are actually rubbing that highly destructive acid into your teeth.
Struggling with the stomach flu
Sleep on your side with your head elevated: If you find yourself vomiting a lot, then sleep on your side with your head elevated.
After receiving the vomiting signal, your stomach muscles contract all at once, which squeezes everything while increasing the pressure. Then all at once the “cover” on your stomach relaxes and the contents of your stomach erupt out.
After your vomiting stops, you may feel weak and lethargic. This is quite common and happens because you haven't eaten in a while. Vomiting may also have left you dehydrated. You also lose electrolytes and salts when vomiting.
Strange colors: Vomit may look bright red or dark (like coffee grounds) if it contains blood. Meanwhile, bile -- a fluid made by your liver that helps with digestion -- can make vomit look bright green. Both are cause for concern. Blood could be a sign of an ulcer or an irritation in your GI tract.
Vomiting
Viral gastroenteritis that causes vomiting is highly contagious. You should always stay home if you are vomiting, and until 24 hours have passed since your last vomit. Again, careful handwashing and hygiene are important to keep the people you live with healthy.
Yellow or greenish-vomit is usually a sign that you are throwing up bile. Throwing up yellow bile could indicate a potentially serious medical concern like a hiatal hernia or intestinal blockage. It can also happen if you have stomach flu or food poisoning and continue to vomit after your stomach is empty.
Do not eat or drink anything for several hours after vomiting. Sip small amounts of water or suck ice chips every 15 minutes for 3-4 hours. Next, sip clear liquids every 15 minutes for 3-4 hours. Examples include water, sports drinks, flat soda, clear broth, gelatin, flavored ice, popsicles or apple juice.
Make an appointment with your doctor if: Vomiting lasts more than two days for adults, 24 hours for children under age 2 or 12 hours for infants.
Sip a little bit of water at a time, but often
Bates said. “Drinking too much too soon can cause the stomach to stretch out and then bounce those fluids right back out.” Instead, take small sips of water every 10 minutes. If you notice you can tolerate it, slowly increase to every few minutes.
Bismuth subsalicylate (2 brand names: Kaopectate, Pepto-Bismol). This medicine may help treat some types of nausea and vomiting, such as from gastroenteritis (stomach flu). They are also used for upset stomachs and as an antidiarrheal (medicine to treat diarrhea).
Gastroenteritis typically lasts in the neighborhood of three to seven days, but sometimes it can be shorter and, unfortunately, sometimes it lasts longer.
