Stomach Flu Treatments & Medications

Stomach Flu Treatments and Medications

medically reviewed by Jesse P. Houghton, MD, FACG What precisely is abdomen influenza ? A bewildering assortment of digestive organization problems are all called “ digest influenza ” or “ stomach hemipterous insect ” —intestinal infections, parasites, food allergies, food poison. however, when it comes to stomach influenza outbreaks, the wrongdoer is largely normally a virus, referred to as viral gastroenteritis .

What is the stomach flu?

viral gastroenteritis ( “ stomach influenza ” or “ digest bug ” ) is a viral contagion of the stomach and intestines that causes diarrhea, nausea, vomiting, stomach pain, and abdominal cramp. While most cases resolve in a few days without serious problems, viral gastroenteritis can be a dangerous and flush dangerous infection in very young children, seniors, or people with immune system problems.

several different viruses can cause stomach influenza, but nine in ten cases are caused by norovirus. Rotavirus is normally the perpetrator when young children come down with stomach influenza, but rotavirus vaccines have drastically reduced the incidence in the United States. other viruses such as adenovirus ( the cold virus ), astrovirus, and sapovirus are responsible for a small number of cases, chiefly among infants and children. The influenza virus, however, never causes stomach influenza, so a influenza shoot does not help prevent stomach influenza. Bacteria can besides cause gastroenteritis, most normally Shigella, Salmonella, Campylobacter, and E. coli. discussion and medications for bacterial gastroenteritis are covered more amply in their own articles. Viral gastroenteritis frequently occurs in outbreaks. close communities such as long-run worry facilities, daycare centers, schools, prisons, and cruise ships are particularly vulnerable to outbreaks. Gastroenteritis viruses spread from person-to-person chiefly through what is called the fecal-oral route. This occurs when microscopic faecal contaminants are incidentally ingested. Contaminated food is the most common causal agent of infection, particularly food that is served raw, washed in contaminated water, or handled after being cooked. however, people can pick up infect faecal material from one-on-one liaison, clothes, furniture, utensil, or even floating in the breeze. Norovirus is a particularly contagious, ruffianly, and durable virus. It can survive extreme point heat, freezing cold, withstand many disinfectants, and survive on surfaces for up to two weeks. For this reason, norovirus is responsible for over half of all foodborne outbreaks. About 21 million people in the United States get sick and about 800 people die from norovirus infection each year. An extra 3 million cases of viral gastroenteritis—almost all infants or very young children—are caused by rotavirus. Most adults and older children, however, are immune to rotavirus. Anyone can catch stomach influenza, but infants, new children, seniors, and people with compromise immune systems are at a higher risk for infection. other risk factors include eating out frequently, attending a daycare focus on or school, living in a nurse home, or staying in cruise ships, hotels, or other partly-closed communities. Poor hand washing habits besides increase the likelihood of a gastrointestinal viral contagion. Most cases of viral gastroenteritis typically resolve in a few days. treatment consists chiefly of supportive caution. dehydration is the most serious complication, so supportive care chiefly focuses on maintaining sufficient hydration. Medications can help with nausea, vomiting, or diarrhea. however, infants, the aged, and people with compromise immune systems may require hospitalization .

How is the stomach flu diagnosed?

Stomach influenza is primarily diagnosed through a forcible examination and a affected role aesculapian history. Most cases will be diagnosed and treated by a general practitioner. Symptoms are the best template for diagnosis. The defining symptom of stomach influenza is unaffixed or watery diarrhea, but other symptoms might include .

  • Nausea
  • Vomiting
  • Abdominal pain
  • Low-grade fever

Loss of appetite, involuntary weight loss, and bloat might besides be experienced. Symptoms of gastroenteritis normally start on the spur of the moment ( or ‘ acutely ’, hence the term ‘ acute gastroenteritis ’ ), coming on in one or two hours. In summation to how cursorily symptoms started, a healthcare provider will want to know :

  • How long have you had symptoms?
  • Do other people you know have similar complaints?
  • Did you eat anything unusual recently, such as raw foods?
  • Did you travel recently, especially outside the country?

A physical examination will help the healthcare professional principle out other conditions. The healthcare supplier will carefully look for signs of dehydration, such as bury eyes, flabbiness, dry mucous membranes ( inside the mouthpiece ), at large skin, or sleepiness. rake or stool tests are not necessary to diagnose a viral gastroenteritis, but a healthcare provider will use them to rule out other causes, such as a bacterial infection, leech infection, or other intestinal problems. Blood or urine tests may be necessary if there are signs of dehydration .

Stomach flu treatment options

Most cases of viral gastroenteritis resolve on their own, typically in one to three days, depending on the virus. treatment of viral gastroenteritis focuses wholly on cope symptoms, particularly dehydration. Bacterial gastroenteritis, the subject of other articles, is treated with both antibiotics and symptom patronize .

Supportive care

The primary focus of supportive care is to maintain hydration and electrolytes. Drinking fluids or using over-the-counter oral rehydration solutions ( internet explorer, Pedialyte, Gatorade, Powerade ) are the principal treatments. IV fluids and hospitalization may be required for more hard dehydration .

Oral rehydration solutions

oral rehydration solutions such as Pedialyte, Hydralite, or Ensure Rapid Hydration, replace fluids and electrolytes lost to vomiting or diarrhea. The electrolytes in many commercially-available oral rehydration solutions are balanced to ensure the most effective fluid assimilation. While commercially-available oral rehydration solutions are better than sports drinks, a combination of ice and water is normally sufficient for handling balmy gastroenteritis .

Antiemetics

Antiemetics ( anti-nausea medications agents ) reduce nausea and vomit by slowing down the part of the brain creditworthy for nausea and the vomit reflex. For mild gastroenteritis, over-the-counter antiemetics such as dimenhydrinate or meclizine are normally sufficient to keep nausea and vomit in check. If severe dehydration is a trouble, a doctor of the church or emergency room doctor may use a more potent prescription drug antiemetic such as ondansetron, metoclopramide ( reduces nausea and vomit by making the stomach narrow ), or prochlorperazine. These drugs may initially be administered intravenously.

Antidiarrheal agents

As a general rule, people with mild gastroenteritis who can stay hydrated shouldn ’ t take antidiarrheal drugs. If dehydration or hard diarrhea is an issue, however, over-the-counter antidiarrheal agents can help. Antimotility agents such as loperamide, work by slowing down the colon. Bismuth salts ( bismuth subsalicylate ) coat the intestinal tissues and prevent urine and electrolytes from being secreted into the stools. Both types of drugs let faecal material build up in stools before being passed .

Dry mouth is a common complaint. The most serious side effect involves a hazardous change in the means the heart beats called QT lengthiness. The risk is greatest when these drugs are taken over a long period. The most normally experienced side consequence of antidiarrheal agents is constipation. Abdominal pain, nausea, and vomiting are besides possible. Bismuth subsalicylate, better known as Pepto-Bismol, contains an component that is closely related to aspirin, so it should not be taken by people with allergies to aspirin, bleeding problems, stomach ulcers, or gastritis. Like aspirin, bismuth subsalicylate can cause Reye ’ s syndrome, a condition that can cause unplayful and even fateful liver and brain damage in children. It should never be given to children or teens with viral gastroenteritis, fever, or any kind of viral infection .
