A stomach bug (gastroenteritis) usually lasts a few days, with vomiting often stopping in 1-2 days, while diarrhea can linger for up to 10 days, though most symptoms resolve within a week, depending on the virus (like Norovirus or Rotavirus). You're contagious during illness and for a couple of days after feeling better, so good hygiene is key.
Self care
The stages of stomach flu infection are:
Overview. Viral gastroenteritis is an intestinal infection that includes signs and symptoms such as watery diarrhea, stomach cramps, nausea or vomiting, and sometimes fever.
You can treat stomach bugs at home by making sure your child keeps drinking fluids and gets plenty of rest. The best way to keep your child well hydrated is with an electrolyte-containing solution such as Pedialyte®. Have your child take small sips frequently — meaning every five minutes or so — throughout the day.
if you notice any signs of dehydration (dry mouth, no tears, no urine for more than 8 hours), bile (green fluid) in the vomit, continuous abdominal pain or crying for more than 2 hours, your baby less than 12 weeks old vomited more than 2 times, fever over 105°F, severe headache or if you suspect diabetes.
Gastroenteritis is often mistaken for stomach flu although it is actually an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Symptoms of gastroenteritis include diarrhea, abdominal pain, vomiting, headache, fever and chills. Most people recover with no treatment.
Signs and symptoms of norovirus infection may start suddenly and include:
The Worst Foods for Your Gastrointestinal System
Norovirus takes one to three days to kick in after exposure, but when it starts it comes on quickly. Often people blame the last meal they had for 'food poisoning,' when in fact the virus had been incubating in their unsuspecting bellies for days.
It's important to note that if diarrhea is caused by bacteria, your body needs to get rid of the bacteria first by letting diarrhea run its course. If they're taken too soon, anti-diarrheal medication can make symptoms worse and keep you from clearing the infection.
Early signs of gastro (gastroenteritis) often start suddenly with digestive issues like nausea, vomiting, diarrhea, and stomach cramps/pain, quickly followed by body-wide symptoms such as tiredness, headaches, muscle aches, and a mild fever, with vomiting often starting before diarrhea. It's an infection of the gut, commonly viral, leading to these gastrointestinal and systemic symptoms, and requires staying hydrated.
If you want your sickness to pass quickly, you need to give your body plenty of rest. Sleep as much as you can and take it easy throughout the day. While you have a stomach bug, you should be lying or sitting down as much as possible. Take it easy and give your body time to rest.
You may not feel like diarrhea is doing anything but making you feel bad. [sigh] But diarrhea is your body's way of working to clear out viruses, bacteria, or other toxins.
