A cautious introduction to gastro intestinal infections will be provided in this blog, their causes, symptoms, treatment and prevention. The general questions linked with the gastrointestinal infections will also be answered, to allow the reader to have a more refined idea on how to treat and prevent them.
What is Gastrointestinal Infection?
A gastrointestinal infection is infection of the stomach or intestines and possibly both of both by microorganisms that damage them, including bacteria, viruses, and parasites which leads to inflammation and digestive dysfunction. The infections can be acquired through contaminated water, food, or even through contact with people or surfaces exposed to people with the infection or in direct contact with infected persons. They are mostly referred to as food poisoning or stomach bugs.
The majority of gastrointestinal infections are light and therefore may go away on their own, though not all infections and some gastrointestinal infections can leading to dehydration, malnutrition and other severe complications.
Causes of Gastrointestinal infections
Bacterial Infections
A bacterial infection is one of the most common causes of gastrointestinal infections. The most common type of bacteria, which can cause gastrointestinal illness, are:
- Salmonella: The Salmonella bacterium frequently attaches itself to raw or undercooked meat, eggs and other dairy items.
- Escherichia coli (E. coli): Escherichia coli possesses some strains, such as E. coli O157:H7, capable of causing severe diarrhea and food poisoning that is typically the result of contaminated water or E. coli-contaminated raw ground beef.
- Campylobacter: It is a type of bacterial pathogen most commonly associated with under cooked chicken which results in abdominal pain, diarrhea and fever.
- Shigella: Bacteria causing dysentery and caused by contaminated water or food.
Viral Infections
Viruses cause another cause of gastrointestinal infections. Viruses are most commonly:
- Norovirus: Norovirus is also commonly referred to as the stomach flu and highly contagious, which makes it the cause of many outbreaks especially in some closed facilities such as cruise ships, nursing homes and schools.
- Rotavirus: It is some of the prevalent causes of diarrhea in small children and infants. Vaccination has been successful in reducing rotavirus infection dramatically.
- Adenovirus: A less common virus that can possibly be a cause of gastroenteritis particularly in children, which results in such symptoms as diarrhea and vomiting.
- Enteric coronavirus: certain coronavirus types of the family such as enteric coronaviruses can cause gastrointestinal syndrome.
Parasitic Infections
Parasites also have gastrointestinal infections, and in many instances can result in chronic symptoms. Examples of some common parasites include:
- Giardia: Giardias is a protozoan parasite that can lead to giardiasis and the outcome can include diarrhea, bloating and cramping. It is normally transmitted in dirty water.
- Amoebiasis: An infection by the parasite Entamoeba histolytica, can result in excessive diarrhea, abdominal pains, and fever.
- Cryptosporidium: This is a sort of parasitic infection that infects the intestines and most likely acquired through polluted water.
Fungal Infections
Fungi may also infect gastrointestinal tract; although rather uncommon. Candida infection such as candidiasis can cause such symptoms as bloating, stomach pains, and bowel changes.

Symptoms of Gastrointestinal Infections
Based on the microorganism causing gastrointestinal infections, they can be associated with various symptoms. However, common signs are:
- Diarrhea: This is one of the most common which can be of different severity. Blood or mucus will explain diarrhea in some of the instances.
- Vomiting: It is usually accompanied by nausea and stomachache.
- Abdominal Pain and Cramping: The inflammatory process caused by the infection can result in pain, bloating and stomach pain.
- Nausea: A feeling that one does not feel so good or wants to vomit.
- Fever: There may be mild to moderate fever, most especially in cases of bacteria.
- Dehydration: Due to the loss of fluids in the diarrhea and vomiting, the most critical complication of gastrointestinal infections is the dehydration. Dehydration symptoms include dry mouth, low urine, vertigo and weakness.
- Headache and Fatigue: Other people may experience general fatigue, muscle pain and headache.
The symptoms can be temporary and timed out. Most gastrointestinal infections tend to disappear in under a few days to a week although some of the gastrointestinal infections may culminate in the presence of a continuing symptomology, particularly, parasitic related infections that may not be treated.
Gastrointestinal Infections Treatment Options
Treatment of gastrointestinal infections is primarily directed towards relief of symptoms, prevention of dehydration and enabling the body to recover. Most of the infections are limited to themselves and they can be cured within a few days but supportive care is noteworthy to ensure recovery.
Hydration
The greatest aspect of gastrointestinal infection management is to be well hydrated. Common complication is dehydration; this is due to the loss of fluids caused by diarrheal and vomiting. A high amount of water intake is significant and oral rehydration solutions (ORS) are even better because they are not only composed of water but also essential electrolytes which are lost as a result of infection.
Rest
Sleep plays a crucial role in helping the body to recover after being infected. Exercise will assist in energy absorption and assist the immune system.
Medications
Antidiarrheal Medications: In some situations, using such over-the-counter medications as loperamide (Imodium) can be used to alleviate diarrhea. However, these are not supposed to be used in case of any bacterial infection that starts with bloody diarrhea or high fever.
- Antiemetics: Such medications as ondansetron cannot be employed to control vomiting and nausea, especially in severe cases.
- Antibiotics: Infection by a bacterial pathogen could be treated with antibiotics, and they may include Salmonella or Shigella. However, they should not be treated using antibiotics as they are viral in nature and antibiotics cannot treat them.
Dietary Recommendations
Until you can eat without having a rush to go to the toilet, do not take solid food. Once the symptoms have become visibly better, begin to consume bananas, rice and toast in small and slow portions as these are bland kinds of food and are easily digested. Snack on spicy and fatty food and dairy until one is done with them.
