You know you're over a stomach virus when vomiting and diarrhea stop, nausea fades, you start feeling hungry for bland foods (like bananas, rice, toast), and have more energy, though you're contagious for about 48 hours after symptoms cease, so continue good hygiene and avoid spreading germs.
You'll notice your symptoms lessening when your immune system has won the battle against the virus. Eventually, your symptoms will stop, and you'll feel better. But you may continue to shed the virus in your poop (stool) for a few days, which means you're still contagious.
Nausea, vomiting or both. Stomach cramps and pain. Occasional muscle aches or headache.

Gastroenteritis also produces significant changes in your intestinal microbiota (the beneficial bacteria that inhabit your intestine). This dysbiosis or bacterial imbalance directly contributes to excessive gas production, as it affects the normal processes of fermentation and food digestion.
It can take several weeks to months to restore the gut's microbiome and heal the intestinal lining after a bout of GI illness. Focusing on restoring gut health post food poisoning or stomach illness may prevent long-term digestive discomfort and imbalances. Nutrition is a key aspect of healing after an illness.
People exposed to Giardia may experience mild or severe diarrhea (loose stool/poop), gas, stomach cramps, nausea (a feeling of upset in the stomach), or dehydration (loss of water in the body causing weakness of dizziness). Some people experience no symptoms at all.

Illnesses like stomach flu can cause temporary weight loss due to vomiting and diarrhea. Most weight loss from being sick is "water weight" and will return when you eat and drink again. Signs of dehydration include dry mouth, dizziness, and decreased urination.
Headaches due to gas typically feel like a dull, pressure-like pain, often around the forehead or temples. You may also experience bloating, nausea, abdominal discomfort, fatigue, and irritability. In some cases, sensitivity to light and sound may also occur.
One of the main reasons norovirus can lead to dizziness is dehydration. The virus causes excessive vomiting and diarrhea, leading to significant fluid loss. Dehydration reduces blood volume, which can lower blood pressure and decrease blood flow to the brain, resulting in dizziness or lightheadedness.
Six common signs of norovirus include sudden vomiting, watery diarrhea, stomach pain/cramps, nausea, headache, and muscle aches, often appearing 12-48 hours after exposure and lasting 1-3 days, leading to potential dehydration.
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.

Gut infections
Some parasitic infections affect how your gut works. The most common gut parasite in the United States is Giardia duodenalis. This can cause giardiasis, a disease that may lead to greasy, foul-smelling, bright yellow diarrhea.
Medications like loperamide (Imodium®) or bismuth subsalicyclate (Pepto-Bismol®) can make the illness last longer. The most important thing you can do is make sure your child gets plenty of fluids so they do not get dehydrated.
Gastroenteritis. 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.
Avoid milk and dairy products, caffeine, alcohol, nicotine, and fatty or highly seasoned foods for a few days. Get plenty of rest. The illness and dehydration can make you weak and tired.
The most common symptoms of giardiasis are diarrhea with loose and pale greasy stools, gas, stomach cramps, bloating, weight loss, and fatigue.
Some of the most common signs of a parasitic infection include:
It infects part of the digestive system called the small intestine. Symptoms include stomach cramps, bloating, upset stomach and loose stools. The parasite that causes giardia lives all over the world, mainly in areas poor sanitation and that don't have safe water.
