Viral gastroenteritis is an inflammation of the stomach and intestines caused by viruses like rotavirus, norovirus, and adenovirus. It spreads easily through contaminated food, water, or surfaces. Symptoms include nausea, vomiting, watery diarrhea, abdominal cramps, headache and fever. Dehydration is a risk, so extra fluids are important. Most cases clear up on their own within a few days with rest and hydration at home. Testing is rarely needed unless symptoms persist.
Defined as inflammation of the mucous membrane of stomach and intestine usually causing nausea ,vomiting and diarrhea.
Gastro-intestinal infections represent a major public health and clinical problem worldwide. Many species of bacteria, viruses and protozoa cause gastro-intestinal infection.

Peptic ulcer ( a medical study)- definition, causes, pathophysiology etc martinshaji
Peptic ulcers include:
Gastric ulcers that occur on the inside of the stomach
Esophageal ulcers that occur inside the hollow tube (esophagus) that carries food from your throat to your stomach
Duodenal ulcers that occur on the inside of the upper portion of your small intestine (duodenum)
It's a myth that spicy foods or a stressful job can cause peptic ulcers. Doctors now know that a bacterial infection or some medications — not stress or diet — cause most peptic ulcers.

"Diarrhoea-This is characterized by 3 or more watery schools per day or having more stools than is normal for that person. Almost everybody has diarrhoea at some point in their lives. Diarrhoea may be a cause of concern because it may cause the more life threatening dehydration. Mindheal homeopathy can help in the treatment of diarrhoea."/>
Gastroenteritis
One of the primary concerns related to gastrointestinal (GI)infection, regardless of the cause, is dehydration, which is the second leading cause of worldwide morbidity and mortality.
Worldwide, dehydration is especially problematic for children younger than age 5.
However, the highest rate of death occurs among the elderly.
Rehydration is the foundation of therapy for GI infections, and oral rehydration therapy (ORT) is usually preferred.
Gastroenteritis, also known as infectious diarrhea and gastro, is inflammation of the gastrointestinal tract—the stomach and intestine.
Diarrhea is defined as the production of stool of abnormally loose consistency, usually associated with excessive frequency of defecation and excessive stool output.
Acute Diarrhea lasts 14 days or less.
Persistent Diarrhea lasts more than 14 days.
Chronic Diarrhea lasts more than 1 month.

3. The digestive system comprises the gastrointestinal tract and
accessory organs. The gastrointestinal tract consists of the oral cavity,
pharynx, esophagus, stomach, small intestine, and large intestine. The
accessory organs are the teeth, tongue, and glandular organs such as
salivary glands, liver, gallbladder, and pancreas.
• The digestive system functions to provide mechanical processing,
digestion, absorption of food, secretion of water, acids,
enzymes, buffer, salt, and excretion of
waste products.
GASTROINTESTINAL
4.
5. INFECTIOUS
01
The GI tract consists
of a long tube with many expanded areas designed
for digestion of food, absorption of nutrients, and elimination
of undigested materials. Transient and resident microbes continuously
enter and leave the GI tract. Most of the microorganisms ingested
with food are destroyed in the stomach and duodenum by the low
pH (gastric contents have a pH of approximately 1.5) and are
inhibited from growing in the lower intestines by the resident
microflora (microbial antagonism). They are then flushed
from the colon during defecation, along with large
numbers of indigenous microbes. The
indigenous microflora of the GI tract.
6. Infectious Diseases
Infectious diseases are those caused by infectious agents - viruses, bacteria,
parasite and fungi
If the organism is invaded by protozoa and helminthsm this is called invasive
disease
Infectious disease are determined not only by its building, chemical structures,
antigenic properties but also nature of its interaction with the microorganism.
8. Colitis
Inflammation of the colon (the large
intestine).
caused by a viral, parasitic or bacterial
infection.
Salmonella and E. coli are common causes.
Most people get it from eating or drinking
contaminated food or water. It's usually
temporary, but some people may need
antibiotics to treat certain infections.
The INFECTIOUS DIEASE of the GI Tract includes the following:
9. Diarrhea
An abnormally frequent discharge of semi solid or fluid fecal matter. Some laboratory
workers define diarrheal specimens as “stool specimens that conform to the shape of the
container.”
Viral gastroenteritis is a common cause of acute diarrhea.
Bacterial infections. Several types of bacteria can enter your body through contaminated
food or water and cause diarrhea.
Common bacteria that cause diarrhea include Campylobacter link, Escherichia coli link
(E. coli), Salmonella link, and Shigella link.
Dysentery
Frequent watery stools, accompanied by abdominal pain, fever, and dehydration. The
stool specimens may contain blood or mucus.
The INFECTIOUS DIEASE of the GI Tract includes the following:
10. Diarrhea
Diarrhea is a symptom in a wide variety of
conditions and diseases. It can be caused
by certain foods or drugs, or it may be the
result of an infectious disease. If diarrhea
results from an infectious disease, the
pathogen may be a virus, a bacterium, a
protozoan, or a helminth. Dysentery may
also be caused by various pathogens,
including bacteria (e.g., Shigella spp.
cause bacillary dysentery) and protozoa
(e.g.,amebiasis and balantidiasis.
The INFECTIOUS DIEASE of the GI Tract includes the following:
11. Enteritis
Inflammation of the intestines, usually referring to the small intestine.
Most often caused by eating or drinking things that are contaminated with bacteria or
viruses. The germs settle in the small intestine and cause inflammation and swelling.
Enteritis may also be caused by: An autoimmune condition, such as Crohn disease.
Gastritis
Inflammation of the mucosal lining of the stomach.
The inflammation of gastritis is most often the result of infection with the same bacterium
that causes most stomach ulcers or the regular use of certain pain relievers.
Gastroenteritis
Gastrointestinal infections are viral, bacterial or parasitic infections that cause gastroenteritis.
Inflammation of the mucosal linings of the stomach and intestines.
The INFECTIOUS DIEASE of the GI Tract includes the following:
12. Hepatitis
Inflammation of the liver; usually the result of viral infection, but can be caused by
toxic agents.
The pain that Hepatitis patients experience is usually in the gastrointestinal tract,
specifically the stomach.
The discomfort can be very severe and may be accompanied by nausea and
vomiting.
In addition to these these problems, Hepatitis C may cause varices or swollen
blood vessels in the esophagus and stomach.
The INFECTIOUS DIEASE of the GI Tract includes the following:
13. Bacterial
02
Bacterial gastroenteritis is a digestive problem
caused by bacteria. Symptoms include nausea,
vomiting, fever, diarrhea, abdominal cramping,
and pain. In severe cases, you may become
dehydrated and have an
electrolyte imbalance.
What is bacterial gastrointestinal?
14. What causes gastrointestinal bacterial infection?
Bacterial gastroenteritis
commonly results from
consuming food or water that
has become contaminated
with bacteria or their toxins. It
can cause a range of
symptoms, including diarrhea,
abdominal cramping, nausea,
and vomiting.
15. Here are six of the most common gastrointestinal problems
Gastroesophageal Reflux Disease (GERD)
It makes a case that small intestine bacterial overgrowth
(SIBO) may be the real cause of GERD.
GERD most often presents as heartburn, but uncontrolled
GERD can erode the lining of the esophagus and lead to
bleeding. The condition can also cause pain in the chest so
extreme that it is sometimes mistaken for a heart attack.
Controlling GERD usually begins with simple lifestyle changes, including
avoiding food for at least two hours before bedtime.
Over-the-counter remedies can also provide some short-term relief for
occasional heartburn, but for chronic or serious GERD, a prescription
medication or even surgery may be necessary.
16. CHRONIC DIARRHEA
Diarrhea is tricky to treat because it can
have so many possible causes. It could
be a result of the body’s inability to absorb
foods as with celiac disease and foods
containing gluten or a disease or disorder,
like irritable bowel syndrome (IBS),
Crohn’s disease or ulcerative colitis.
Infections often viral and even parasites
can also be to blame.
Here are six of the most common gastrointestinal problems
17. Here are six of the most common gastrointestinal problems
Chronic constipation is typically defined as having
fewer than three bowel movements a week for
three weeks or longer. It may also be the case that
stools are hard and difficult to pass.
Treating the condition can begin with over-the-
counter remedies, such as stool softeners and
fiber supplements. Adding more fluids to your
diet — namely, water — may help.
If those fail to bring relief, a physician may
recommend some exercise to strengthen the
muscles that move the stool through the bowels.
CHRONIC CONSTIPATION
18. Here are six of the most common gastrointestinal problems
GASTROENTERITIS
Gastroenteritis is caused by an infection either viral or bacterial in the gut. Bacterial
infections can be caused by E. coli or salmonella, while viral infections can include
rotavirus or that infamous scourge of cruise ships, norovirus. Parasites, too, can cause
gastroenteritis.
The best advice is to drink plenty of fluid to avoid dehydration and try to make the best of
it.
Use good hand hygiene to prevent spreading the infection and, if at all possible, ask
others not to use the same bathroom facilities until your symptoms stop and you have a
chance to sanitize the facilities.
19. Here are six of the most common gastrointestinal problems
GASTROENTERITIS
Symptoms lasting more than a few
days require further observation,
which may include testing for
antibodies that could indicate an
allergy or signs of infection in the stool
that can help a physician prescribe the
most effective treatment.
20. ULCERS
The bacteria or NSAIDs can damage the mucus that lines the inside of the
stomach, exposing the interior of the stomach to acid which irritates the tissue
and causes the peptic ulcer. Essentially a sore on the inside of the stomach,
these can be very difficult to resolve because of the constant exposure to
stomach acid.
A physician can run tests to determine if the peptic ulcer is caused by an
infection (usually H. pylori) and prescribe antibiotics for treatment.
A proton pump inhibitor to reduce the acid in the stomach is also often
prescribed. Untreated, ulcers can not only cause pain, but may bleed,
leading to anemia.
Here are six of the most common gastrointestinal problems
22. Here are six of the most common gastrointestinal problems
Hemorrhoids tend to cause pain or itching around the anus. You
may notice a hard knot near the anus or even bright red blood in
the toilet bowl.
You can try treating hemorrhoids at home. Over-the-counter
ointments and cold packs can shrink the inflamed tissue.
Soaking in plain, warm water can help make the tissue softer,
enabling it to heal.
HEMORRHOIDS
23. Here are six of the most common gastrointestinal problems
If these don’t work, consult a
physician. He or she can
recommend additional treatment,
including rubber band ligation,
which uses rubber bands to
prohibit blood flow to the
hemorrhoid, and sclerotherapy, in
which a small needle is used to
inject medication into the vessels
and cause them to shrink.
HEMORRHOIDS
24. 03 VIRAL
Viruses are pathogens that commonly infect
immunocompromised patients.Viral infections are illness
you get from tiny organism that use your cells to make
more copies of themselves (viruses). Viral infections
commonly cause respiratory and digestive illnesses,
but viruses can also infect most other parts
of our body.
25. Mumps
Mumps is an acute viral infection of the
salivary glands; parotid glands (Parotitis)
T h e m u m p s v i r u s b e l o n g s t o t h e
paramyxovirus family
• RNA virus
Humans are the only source of the virus
Symptoms include fever, headache, sore
throat, face pain and swelling of the
parotid glands
Transmission is by direct contact or by
inhaled respiratory droplets
Cold sores
(fever blisters)
Caused by herpes simplex virus Type
I (HSV-1)
• DNA virus
HSV-1 exhibits a latent infection cycle
that is extremely widespread
because it is easily transmitted by
close physical contact with saliva or
the lesions
COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
Viral Disease of the Upper GI Tract
27. VIRAL GASTROENTERITIS
Is an inflammation, swelling, and irritation of
the inside lining of your gastrointestinal tract.
A virus causes this illness. “Stomach Flu”
It can infect yout stomach, small intestine, and
large intestine.
Viruses can be found in the vomit and the
diarrhea of infected people. It can live for a
long time outside the body. People who are
infected can spread the virus to objects they
touch, especially if they don’t wash their
hands.
COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
29. ROTAVIRUS
Rotavirus is a very contagious virus that causes
diarrhea. Before the development of a vaccine, most
children had been infected with the virus at least once
by age 5.
Although rotavirus infections are unpleasant, you can
usually treat this infection at home with extra fluids to
prevent dehydration. Occasionally, severe dehydration requires
receiving fluids through a vein (intravenously) in the hospital.
Good hygiene, such as washing your hands regularly, is
important. But vaccination is the best way to prevent
rotavirus infection.
KINDS OF VIRUSES OF GASTROINTESTINAL TRACT
30. Noroviruses are very contagious.
They are found in the stool (feces) or vomit of infected
people.
From there, noroviruses are transferred to food, water, or
surfaces by the hands of infected people who have not
washed adequately after using the bathroom.
Noroviruses are a group of
viruses (previously known as
Norwalk-like viruses) that
can cause gastroenteritis, an
inflammation of the stomach
and intestines.
Norovirus is the leading
cause of foodborne illness
outbreaks in Minnesota.
KINDS OF VIRUSES OF GASTROINTESTINAL TRACT
NOROVIRUS
31. These people might not have any symptoms, but
are still be able to spread the virus to others.
Adenovirus serotypes 40 and 41 are the most
common cause (5–20%) of acute gastroenteritis in
young children [5–8].
Adenovirus infections are
most contagious during the
first few days of symptoms.
Some people, especially
t h o s e w i t h w e a k e n e d
immune systems, can carry
the virus in their tonsils,
adenoids, or intestines for
weeks or longer.
KINDS OF VIRUSES OF GASTROINTESTINAL TRACT
ADENOVIRUS

33. Signs of dehydration:
Decreased urine output
Dark-colored urine
Dry skin
Thirst
Dizziness
Common symptoms include:
Nausea
Vomiting
Watery diarrhea
Other possible symptoms are:
Headache
Fever
Chills
Stomachache
What are the symptoms of viral gastroenteritis?
Symptoms of viral gastroenteritis usually begin about 1 to 2 days after the virus gets
into the body.
Signs of dehydration in young children:
Dry diapers (from a lack of urination)
Lack of tears
Dry mouth
Drowsiness
Sunken fontanel (the soft spot on the top of
an infant’s head)
34. • Your healthcare provider will most likely
diagnose your condition based on your
history and symptoms. You will rarely
need testing. If your symptoms persist,
your healthcare provider may ask for a
stool sample to look for viruses, bacteria,
and parasites.
How is viral gastroenteritis diagnosed?
35. 4. Avoid any food or
water with warnings
of contamination.
1. Wash hands for 20 seconds with soap and water after going to the bathroom, after
changing a diaper, and before touching any food.
2. Use alcohol-based sanitizers.
3. If someone in the house has gastroenteritis, wash all surfaces that might be
contaminated with a
bleach-based cleaner.
PREVENTION
Vaccines are available to protect children
from rotavirus. Healthcare providers give
shots to babies before age 6 months. You
and your children can help prevent viral
gastroenteritis by taking these steps:
36. Helpful home care tips include:
Drink plenty of light fluids like water, ice chips, fruit juice, and broth. Keep in mind that
sports drinks are high in sugar and are not appropriate if you are extremely
dehydrated. In this case, you will need an oral rehydration solution.
Avoid drinks that contain milk, caffeine, and alcohol.
Once you feel hungry
again, start with mild,
easy to digest foods.
Rehydrate children
with oral rehydration
solutions.
TREATMENT
Specific treatment is usually not needed. In
most cases, you simply need to drink plenty
of fluids and rest at home until the virus
leaves your system. In rare cases, you may
need treatment for severe dehydration, with
IV (intravenous) fluids.
37. 04FUNGAL
Fungi are pathogens that commonly infect
immunocompromised patients. At present, the incidence of
these pathogens in disease causation is gradually increasing
as a result of increased use of immunosuppressive drugs,
chemotherapy, and transplantation as well as infections
with the human immunodeficiency virus. Fungal
infections can affect any organ, including
those of gastrointestinal tract.
38. COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
Oral Thrush (Oral candidiasis)
is a condition in which the fungus
Candida albicans accumulates on the
lining of your mouth. Candida is a
normal organism in your mouth, but
sometimes it can overgrow and cause
symptoms.
39. Intestinal candidiasis
Intestinal Candidiasis (IC) refers to an
overgrowth of the Candida yeast genus
in the small and large intestines. Its
presence in the gut is normal, but it can
be overabundant in certain populations
like premature infants and the
immunocompromised. Probiotics and
antifungal drugs may prevent IC
COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
40. COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
SIFO
Small intestinal fungal overgrowth (SIFO) is
characterized by the presence of excessive
number of fungal organisms in the small
intestine associated with gastrointestinal (GI)
symptoms.
Candidiasis is known to cause GI symptoms
particularly in immunocompromised patients
or those receiving steroids or antibiotics
41. Gastric Mucormycosis
is an opportunistic, life-threatening fungal infection
caused by fungi of the class Zygomycetes.
The disease has traditionally been reported in
immunocompromised patients, premature infants,
diabetics, transplant recipients, prolonged use of
corticosteroids or in condition associated with
increased availability of serum iron such as
acidosis or deferoxamine administration.
The infection is progressive and associated with a
high mortality unless treatment is initiated promptly.
COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
42. COMMON MICROBIAL DISEASES OF GASTROINTESTINAL TRACT
Gastrointestinal aspergillosis
Aspergillosis is an opportunistic infection
commonly seen in immunocompromised
patients.Patients with hematological malignancies,
postorgan transplantation, or those with comorbid
conditions are susceptible to the development of
invasive aspergillosis. Aspergillosis can involve
the gut, causing vascular thrombosis leading to
ischemia and necrosis of the gut wall, resulting in
perforation.
43. FUNGAL
Signs and symptoms
of gastrointestinal
fungal infections
diarrhea
vomiting
melena
hemorrhage
abdominal pain
and fever
and are often similar
regardless of the type
of fungus involved.
44. 05 PARASITIC
According to the Nicklaus Children’s Hospital,
When the gastrointestinal tract, most often the
intestine, is infected by a parasite, this is often
referred to as gastrointestinal parasites. If not
treated some parasites may linger for many
years and cause long term problems.
What is Gastrointestinal Parasites?
45. TAPEWORMS
A tapeworm is a parasite that can live and feed in human intestines. This is called a
tapeworm infection. A young and inactive form of the tapeworm is called a larval cyst.
It can stay alive in other parts of the body. This is called a larval cyst infection.
The sizes are about 1 mm (0.04 inch) to more than 15 m (50 feet)
Their lifespan, the left untreated, adult tapeworms can live in a host body for up to 30
years. Their length varies, but they can grow to be anywhere from 6 to 22 feet
Morphology. This is the longest tapeworm in humans – 3-10 m in length. It has
>3,000 proglottids which are more broad than long. The scolex is shaped as two
almond leaves.
The common types of gastrointestinal parasites includes:
46. ROUNDWORMS
Roundworms are a group of parasites that includes pinworms and ascariasis.
Roundworms can live inside the small intestine for up to 2 years. The worms
are about as thick as a pencil. They can grow to be about 13 inches long.
External morphology: A live roundworm is generally dull white in
colour. Itlooks tubular like the earthworm. In the body of roundworm,
we can see four longitudinal lines, one dorsal, one ventral and two
laterals in position. In length, the female roundworm can be up to
20-25 cm while the male is up to 15-20 cm.
The common types of gastrointestinal parasites includes:
48. Most parasitic protozoa in humans are less than 50 μm in
size. The smallest (mainly intracellular forms) are 1 to 10
μm long, but Balantidium coli may measure 150 μm.
Protozoa are unicellular eukaryotes. As in all eukaryotes,
the nucleus is enclosed in a membrane.
Protozoans are single-celled eukaryotes.
Protozoa are microscopic,
one-celled organisms that can
be free-living or parasitic in
nature. They are able to
multiply in humans, which
contributes to their survival
and also permits serious
infections to develop from just
a single organism.
The common types of gastrointestinal parasites includes:
PROTOZOA
49. Risk factors for gastrointestinal
parasites include:
International travel
Poor sanitation
Living or visiting an area known to
have parasites
Poor hygiene and Age
Weakened immune system
Exposure to
child and
institutional
care centers
50. The symptoms of
gastrointestinal parasites
Many gastrointestinal parasites can live in the
intestines for many years without causing any
symptoms. Some of the symptoms they may cause
include: diarrhea, nausea, vomiting, abdominal pain,
bloating, fatigue, weight loss and other symptoms.
People can get infected with intestinal parasites by
eating contaminated food or water or by coming in
contact with contaminated soil.
51. Gastrointestinal parasites care options?
Medications are typically
effective at eliminating
gastrointestinal parasites and
returning the patient to health.
