What is Gastroenteritis ?

An irritated and inflamed stomach and intestines are known as gastroenteritis. This may result in nausea, vomiting, diarrhea, cramps in the abdomen, and vomiting. Usually, your immune system's reaction to a bacterial or viral infection is what causes inflammation. However, gastroenteritis can also result from chemical irritants, fungal infections, or parasitic diseases.

It's possible that you've heard of "stomach flu." When individuals refer to this, they typically imply viral gastroenteritis. But influenza, a separate virus that affects your upper respiratory tract (speech, throat, and lungs), is unrelated to it in reality.

Symptoms of Gastroenteritis

Symptoms of gastroenteritis often appear suddenly. Usually, you'll experience vomiting, diarrhea, cramps, and nausea. You should prepare to make multiple quick trips to the bathroom. Additional symptoms, which usually appear a little later, consist of:

• Stomach ache
• Appetite decline 

• Feeling cold

• Weakness, aches in the body, fever

Additionally, vomiting and diarrhea can induce dehydration. Keep an eye out for symptoms of dehydration, such as excessive thirst, lightheadedness, dry lips, and dry skin. If you experience any of these signs, give your doctor a call.

What is the duration of gastroenteritis?

Depending on what led to it. However, the average duration of acute gastroenteritis is 14 days. In contrast to chronic gastroenteritis, which lasts more than 30 days, persistent gastroenteritis lasts between 14 and 30 days.

Children and Stomach Flu

Dehydration can strike children and babies very fast. Should they do so, they must see a physician right away. Among the symptoms of pediatric dehydration are:

• Sunken eyes and a tender place on your baby's head
• mouth dryness
• They weep but don't cry; they urinate or urinate very little; they are lethargic and have low vitality.
• Intolerance

Gastroenteritis can spread easily when it is brought on by an infection, most frequently a virus. There is a higher chance of severe symptoms in young children. Until all of their symptoms are gone, keep kids with gastroenteritis out of daycare centers and schools.

There are two oral vaccines available to help shield kids against rotavirus infection, which is one of the most frequent causes of viral gastroenteritis. RotaTeq and Rotarix are the names of the two vaccinations. They are available to kids as early as two months of age. Consult your physician regarding your child's vaccination status.
Before giving your child any medication, consult your physician. Generally speaking, doctors advise against using over-the-counter medications to children under the age of five to treat vomiting.

 Additionally, they advise against prescribing medications to children under the age of 12 to treat diarrhea (some doctors will not recommend them for persons under 18).

Causes of Gastroenteritis

A virus is the most frequent cause of gastroenteritis. The two primary kinds are rotavirus and norovirus. Typically, a virus exposes you through:


Interaction with an infected person
Eating food handled by someone infected, sharing food or utensils
eating or drinking food or water tainted with the virus
contacting contaminated surfaces and then entering your mouth with unwashed fingers

 

The norovirus

The norovirus spreads swiftly and easily because it is very contagious.


After being exposed, symptoms typically appear 12 to 48 hours later. After you start feeling better, you could be contagious for up to two weeks. You'll likely be unwell for one to three days.

 
Rotavirus

Rotavirus can affect both adults and children, however children are more prone to experience severe symptoms including extreme dehydration. Although it can be obtained at any time, the United States has a seasonal increase from January to June. Children are most likely to contract it at that time, and they can quickly infect friends and relatives that they interact with frequently.

It normally takes one to three days following exposure for you to begin experiencing effects. After you start feeling better, you'll likely remain contagious for a few days and stay unwell for five to seven days at most.

Astrovirus

Watery diarrhea is typically the only sign of an infection caused by an astravivirus. Although most individuals have immunity because they have had an infection in the past, anyone can contract it. Most often, infections occur in:
Younger than five adults 65 years of age or older
Individuals with cancer, immunosuppressive medications, or HIV infection who have compromised immune systems

After being exposed, symptoms often appear 4-5 days later, and you'll likely be unwell for 1-4 days at that time.
Adenovirus

The adenovirus has several strains. Fever, runny nose, and cough are typically the symptoms of one of these infections. However, viral infections might occasionally result in stomach issues. Although anyone can catch HPV, children under the age of five are more likely to have it. Adults who contract it typically do it as a result of living in denserly environments, like nursing homes, military housing, or dorms. Additionally, you may become quite ill if you have a compromised immune system, which increases your risk of contracting it.
Microbes

Salmonella and Escherichia coli are two other bacteria that can cause the stomach flu. However, compared to viral cases, this is less frequent.


In the United States, the most frequent bacterial causes of gastroenteritis are campylobacter and salmonella. Typically, undercooked poultry, eggs, or poultry fluids are the carriers of these germs. Additionally, live poultry or pet reptiles can transmit salmonella.

In daycare centers, shigella is another bacteria that is frequently spread. Although HIV usually spreads from person to person, tainted food and water are also major sources of transmission.
Stages of Stomach Flu
There are usually four stages of viral gastroenteritis:


Being exposed. This is the moment the virus first makes contact with you. You probably won't realize you were exposed until you start feeling ill because symptoms typically take awhile to manifest.

Embryology. It takes some time for the virus to enter your body and begin reproducing once you've been exposed. We refer to this as the incubation period. Generally speaking, it lasts one to ten days, depending on the virus that infected you.

acute infection. You'll experience inflammation while your body fights the illness. This is what starts your symptoms, which, depending on the kind of virus you have, might linger anywhere from one to fourteen days.

recuperation. Your symptoms begin to subside during this time, and you'll feel superior. However, depending on which virus caused your infection, you could be contagious for up to two weeks later.

Pregnancy and stomach flu

It is typical to get gastroenteritis during pregnant. Gastroenteritis affects about 30% of expectant mothers at some point during their pregnancy. If you don't get treated, dehydration might lead to early labor. See your doctor right away if you are pregnant and find it difficult to swallow clear liquids.

Treatment for Gastroenteritis

Most persons with gastroenteritis won't require special care. It's conceivable that after a few days you'll heal on your own. Remaining hydrated, eating bland food, and getting enough of relaxation at home are the best ways to hasten your recuperation.

• To be well hydrated:Consume as much watery liquid as you can. Try taking little sips throughout the day if you're feeling queasy, or eat some ice chips.
• Eat items that are easy to digest and contain electrolytes, like fruit juice, popsicles, broths, and saltine crackers, in little amounts if you can.

• Give a kid suffering from gastroenteritis a hydration solution, like Pedialyte, to drink as they can get dehydrated very rapidly.

Preventing Gastroenteritis

The infections that cause gastroenteritis can never be completely avoided. On the other hand, there are actions you may do to lower your chance of becoming ill and infecting others, like:

• Hands up. One of the most crucial and straightforward methods of infection prevention is this one. For at least 20 seconds, wash your hands with soap and water.

• Make sure all surfaces are completely cleaned. Scrub and sanitize every surface that is shared and harbors bacteria.

• Use caution when handling food. Both before and after handling food, wash your hands. Prior to eating, wash fresh fruits and vegetables. Safely prepare, serve, and keep food.

• When traveling, eat carefully. You may not normally come into contact with pathogens when traveling. You can get traveler's diarrhea with this. Drink bottled water and limit your diet to packed, peeled, or cooked foods to prevent this.
