Gastroenteritis

The infection or inflammation of the gastrointestinal tract (stomach lining and the intestine) is referred to as gastroenteritis. Also known as gastro, this condition is fairly common and does not have serious consequences for most adults. If the patient’s body loses more fluid than it can replace as a result of the illness, it can lead to severe dehydration.

Healthy adults who encounter this disease are most likely to recover without any severe complications within two weeks. 

The Risk of Complications Arising from Gastroenteritis increases in the Following individuals:

• Infants

• Old people

• People who have a compromised immune system or a pre-existing illness

The illness is mostly characterized by symptoms like diarrhea, nausea or vomiting, loss of energy, and abdominal cramps. Fever is also a common observation in the case of acute gastroenteritis as a result of the body’s immune response to the infection.

What Causes Gastroenteritis?

The most common gastroenteritis causes are viral infections, although it can also be caused by bacteria, parasites, and other microorganisms. These microbes produce harmful toxins that can lead to the diarrhoea by promoting the loss of electrolytes from the body. 

People mostly contract this disease through direct contact with a person who is already affected or by the intake of food or water that is contaminated. This can lead to inflammation of the gut, which leads to loss of absorption of nutrients. There is excessive loss of water and salts from the body. The gastroenteritis treatment involves making up for this loss of fluids and electrolytes. 

Viral Gastroenteritis

The most common type of gastroenteritis is viral gastroenteritis, also known as viral diarrhoea. It can be caused by the following:

• Rotavirus

• Calicivirus

• Norwalk virus

• Adenovirus

Viral diarrhoea is also referred to as stomach flu and can be avoided by taking proper preventative measures. Vaccines for children against viruses like rotavirus can also prevent the development of this disease.

Bacterial Gastroenteritis 

Another common form of this illness is bacterial gastroenteritis, also known as food poisoning. This is caused by the consumption of contaminated food and water. Symptoms like extreme abdominal pain, nausea and vomiting are apparent in people who have acquired this infection. This type of gastro infection can be treated by taking adequate rest and drinking plenty of fluids to make up for the lost salts and water from the body.

Eosinophilic Gastroenteritis

This form of gastric infection does not have a known cause, but most people have a family history of allergy or hypersensitivity to a certain type of food. The symptoms of eosinophilic gastritis include weight loss, abdominal pain, bleeding, nausea etc. The disease involves the infiltration of eosinophils into the stomach and intestine. This is one of the rarer forms of the disease.

Traveller’s Diarrhoea

This is another common form of gastric infection caused by toxins produced by Escherichia coli. This condition is seen in people who have travelled to a location with unsanitary conditions such as contaminated water or food. Traveler's must take care of the hygiene and safety of the food and water they consume to prevent this disorder.

The Severity of the Disease

If you are otherwise healthy, you will be free of the disease’s symptoms in a few days. In some cases, the disease may advance into a severe case of dehydration. In such cases, it is important to seek the counsel of a healthcare professional. 

Symptoms Associated with the Condition

The most pertinent gastro symptoms are watery diarrhea and vomiting. This is also accompanied by other conditions such as:

• Fever and chills

• Nausea

• Stomach ache

• Cramps

• Weakness or fatigue

• Headache 

• Feeling dizzy or lightheaded

How does Gastro Treatment Work?

The treatment of this condition is determined based on what caused the disease and how far it has progressed. The gastro treatment for most patients involves the use of antibiotics and providing supportive care. Prevention of the disease is the best way to avoid any serious complications. 

Healthy adults are likely to recover on their own, but infants and older adults have a risk of dehydration. In cases of severe dehydration, fluids are transferred to the patient’s body intravenously. Although rare, severe dehydration may be life-threatening in case of a suppressed immune system or pre-existing illnesses.
