The stages of stomach flu (viral gastroenteritis) generally follow exposure, incubation, an acute phase with peak symptoms (vomiting, diarrhea, cramps), and a recovery phase, though you remain contagious even as you feel better. Key stages include the incubation period (1-3 days before symptoms), the acute phase (sudden, intense symptoms for 1-3 days), and recovery, where symptoms fade but contagiousness can linger.
During the initial 24 to 72 hours, you'll likely experience the most intense symptoms, including vomiting, diarrhea, and abdominal cramps. This is the acute phase of the illness. Gradual improvement. After this acute phase, you should notice a gradual improvement in your condition.
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.
Some infections like traveler's diarrhea, gastroenteritis, and food poisoning can be associated with other body symptoms that might include enlarged lymph nodes (glands).
Peak symptoms: The symptoms of norovirus often peak within 24 to 48 hours after they begin. This is when the vomiting and diarrhea can be most severe. Duration: In most cases, the symptoms gradually subside over the course of 1 to 3 days.
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.
Self care
If you're an adult, call your health care provider if: You're not able to keep liquids down for 24 hours. You've been vomiting or having diarrhea for more than two days. You're vomiting blood.
Symptoms
Does drinking a lot of water help swollen lymph nodes? Drinking plenty of water can help avoid dehydration and promote good lymphatic system function.
Symptoms usually only last one to three days, but those are memorable days. Vomiting can be repetitive and violent, and may coincide with the diarrhea. Nausea is very common.
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.
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.
Make an appointment to see a doctor if you have:
Stage 1: The Sneaky Start
At first, the flu might feel like a simple cold. You may have a sore throat, mild body aches, or a little fatigue. Some people may also experience nausea, vomiting, or diarrhea at the start of their flu infection.
With norovirus, you can be contagious before you feel ill. Symptoms usually appear within 1 to 2 days being exposed to the virus. Most people with norovirus feel better a day or two after their symptoms begin. But they're contagious for a few days after they recover.

Other Signs of Lymphoma
If the lymphoma involves lymphatic tissue within the abdomen, bowel or stomach, fluid may build up causing swelling near the intestines, potentially leading to sensations of abdominal pressure, pain, diarrhea and/or indigestion.

Gastroenteritis Versus Appendicitis
Because of the location of the pain, it can be mistaken for a stomach bug. Although certain symptoms, like diarrhea, stomach pain, and vomiting, may occur in both appendicitis and gastroenteritis, there are distinctions between the two conditions.
Other symptoms: Talk to your doctor if you also experience any of the following:
Signs Your Stomach Pain May Be Serious
Certain types of pain and symptoms could mean your abdominal discomfort is more than a stomachache. You should seek medical care if you have any of these symptoms in addition to pain: An abdomen that is tender to the touch or swollen. Pain with a high fever or prolonged vomiting.
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.
Sip beverages throughout the day, including water, electrolyte drinks (sports drinks or Pedialyte), ginger or peppermint tea to relieve nausea, and clear broths. If drinking liquids is difficult, suck on ice chips or ice pops to slowly replenish fluids without overwhelming your stomach.
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.
