An intestinal infection is an inflammation or irritation of the intestines. It may be caused by bacteria, viruses, parasites, or other microorganisms. The symptoms of an intestinal infection include diarrhea, abdominal pain, nausea, vomiting, fever, and fatigue.
Symptoms include nausea, vomiting, fever, diarrhea, abdominal cramping, and pain. In severe cases, you may become dehydrated and have an electrolyte imbalance. Bacterial gastroenteritis is sometimes treated with antibiotics.
Gastroenteritis can be very unpleasant, but it usually clears up by itself within a week. You can normally look after yourself or your child at home until you're feeling better.

Overview. Viral gastroenteritis is an intestinal infection that includes signs and symptoms such as watery diarrhea, stomach cramps, nausea or vomiting, and sometimes fever.
Enteritis is inflammation of your small intestine. It may also include your stomach (gastroenteritis) or colon (enterocolitis). It's usually caused by a viral, bacterial or parasitic infection (food poisoning, stomach bug or the stomach flu). Sometimes it's caused by radiation, drugs or disease.
Symptoms include: Diarrhea (often loose and watery with Crohn's disease or bloody with ulcerative colitis) Severe or chronic cramping pain in the abdomen. Loss of appetite, leading to weight loss.
Narrow or pellet-like stools: if you have advanced or severe diverticulitis, your large intestine may narrow, causing stool to become thin, narrow, or pellet-shaped.
“When the bacteria in your gut becomes imbalanced, you'll likely experience physical symptoms like gas, bloating, irritated bowel, heartburn and even unintentional weight gain or loss.”
Bacteria (E. coli, Salmonella, Shigella, Campylobacter, Clostridium), viruses ( Norwalk agent, Rotaviruses), and parasites (Giardia, Entamoeba, Ascaris) can all cause disease in the intestines. Most of the time infections of the intestines result in diarrhea or dysentery, nausea, vomiting, and abdominal cramping.
For most people, the initial way to treat bacterial overgrowth is with antibiotics. Doctors may start this treatment if your symptoms and medical history strongly suggest this is the cause, even when test results are inconclusive or without any testing at all.
In some cases, symptoms are gone in 1or 2 days. In others, symptoms linger for weeks. In certain cases, it can take months for your bowels to return to normal.
Colonoscopy and Biopsy
Gastroenterologists almost always recommend a colonoscopy to diagnose Crohn's disease or ulcerative colitis. This test provides live video images of the colon and rectum and enables the doctor to examine the intestinal lining for inflammation, ulcers, and other signs of IBD.
Gastrointestinal infections can be bacterial, viral, or parasitic. No matter the cause, the symptoms are unpleasant and can include diarrhea, abdominal cramping, and nausea. Most infections will resolve on their own, but if a person has symptoms of dehydration or other complications, they should see a doctor.
Without treatment, symptoms may persist and get worse, and inflammation may spread within the colon. There is also a risk for further damage to the lining of the colon with every flare-up. This can make it harder for a person to manage the condition, going forward.
Treatment often involves intravenous nutrition to allow the bowel to rest, which typically resolves the disease within one or two weeks.
It depends on what type of intestinal infection you're suffering from. While certain conditions, such as a food-borne illness, can be beaten within 24 hours, others, like certain parasites, can take months to get over.
Unlike viral gastroenteritis, food poisoning is strictly based on what you eat. It can be caused by bacteria, parasites and viruses. And just like with the stomach flu, you may experience the same symptoms of nausea, vomiting, diarrhea, abdominal cramping and fever.
Gastritis tends to affect the lining of the stomach, whereas gastroenteritis affects the intestines. Gastritis is inflammation, or irritation, of the stomach lining. Gastroenteritis, on the other hand, is inflammation of the intestine, or the stomach and the bowel.
