2. Diarrhea
Definition
Every person, every so often, has diarrhea: more frequent bowel movements with soft and
liquid stools.
In most cases, the diarrhea lasts a couple of days. However, if diarrhea persists for weeks, it
can indicate a serious disorder, such as a persistent infection, an inflammatory bowel
disease, or a less serious condition, such as irritable bowel syndrome.
Etiology
Various diseases and conditions can cause diarrhea, including the following:
Different viruses. Viruses that can cause diarrhea include norovirus, cytomegalovirus and
hepatitis virus. Rotavirus is a frequent cause of acute infantile diarrhea.

3. Bacteria and parasites. Through contaminated food and contaminated water, bacteria and
parasites are transmitted. Parasites, such as Giardia lamblia and Cryptosporidium, can cause
diarrhea.
Bacteria that frequently cause diarrhea include Campylobacter, Salmonella, Shigella, and
Escherichia coli. When one travels to developing countries and has diarrhea caused by
bacteria and parasites, the phenomenon is often called "traveler's diarrhea." Clostridium
difficile infection may occur, especially after taking a course of antibiotics.
Medicines. Many medications, such as antibiotics, can cause diarrhea. Antibiotics destroy
good and bad bacteria, which can upset the natural balance of bacteria in the intestines.
Anti-cancer drugs and antacids that contain magnesium can also cause diarrhea.
Lactose intolerance Lactose is a form of sugar found in milk and other dairy products.
People who have difficulty digesting lactose experience diarrhea if they eat dairy products.
The body makes an enzyme that helps digest lactose, but in most people, the level of this
enzyme decreases rapidly after childhood. As a consequence, the risk of having lactose
intolerance increases as one grows.
Fructose. Fructose, a form of sugar that is found naturally in fruits and honey, and added as
a sweetener to some beverages, can cause diarrhea in people with problems digesting it.
Artificial sweeteners. Sorbitol and mannitol, artificial sweeteners found in chewing gums
and other sugar-free products, can cause diarrhea in people without other diseases.
Surgery. Some people have diarrhea after having undergone abdominal surgery or surgery
to remove the gallbladder.
Other digestive disorders Chronic diarrhea has many other causes, such as Crohn's disease,
ulcerative colitis, celiac disease, microscopic colitis, and irritable bowel syndrome.
Signs and symptoms
Signs and symptoms associated with diarrhea may include:
 Soft, watery stools
 Abdominal cramps
 Abdominal pain
 Fever
 Blood in the stool

4.  Swelling
 Sickness
 Urgent need to evacuate the intestines
If you are an adult, check with your doctor if:
 to diarrhea continues after 2 days
 You get dehydrated
 You have severe pain in the abdominal or rectal area
 You have blood in your stool or very dark stools
 You have a fever higher than 102 ° F (39 ° C)
 In the case of children, particularly young children, diarrhea can cause dehydration
quickly.
Call your doctor if your child's diarrhea does not improve within 24 hours or if your baby:
 It dehydrates
 Has a fever greater than 102 ° F (39 ° C)
 Presence of blood in the stool or very dark stools
Diagnosis
In addition to performing a physical examination and reviewing the medications you take,
your doctor may request tests to find out what is causing you diarrhea. Some of them are:
Blood test. A complete blood count can help determine what causes diarrhea.
Fecal matter analysis. The doctor may recommend a stool test to determine if the diarrhea is
caused by bacteria or a parasite.
Flexible sigmoidoscopy or colonoscopy. The doctor may recommend one of these studies
to look at the walls of the colon and take samples for biopsy if there is no obvious cause of
persistent diarrhea.
Both studies use a thin, lighted probe with a lens at the end that allows the inside of the
colon to be seen.

5. Treatment
In most cases, diarrhea goes away on its own (without treatment) in a few days. If you tried
to make lifestyle changes and use home remedies to relieve diarrhea and you did not
succeed, your doctor may recommend medications and other treatments.
Antibiotics
Antibiotics may help treat diarrhea caused by bacteria or parasites. If a virus is to blame for
your diarrhea, antibiotics will not help you.
Treatment to replace liquids
Your doctor may advise you to replace fluids and salts. For most adults, that means
drinking water, juice or broth. If drinking liquids makes your stomach hurt or causes
diarrhea, your doctor may recommend receiving fluids through a vein in your arm
(intravenously).
Water is a good way to replenish liquids, but it does not contain the salts and electrolytes
(minerals such as sodium and potassium) necessary to maintain the electric currents that
allow the heart to beat. You can maintain electrolyte levels by drinking fruit juices to
replenish potassium or soups to replenish sodium. Certain fruit juices, such as apple juice,
may make diarrhea worse.
In the case of children, consult the doctor about the use of an oral rehydration solution, such
as Pedialyte, to prevent dehydration or replenish lost fluids.
Adjust the dosage of the medications you are taking
If the doctor determines that an antibiotic is the cause of your diarrhea, the dose will be
reduced or replaced by another medication.
Treatment of undiagnosed conditions
If the diarrhea is due to a more serious condition, such as inflammatory bowel disease, the
doctor will take care of controlling that condition. You may be referred to a specialist, such
as a gastroenterologist, who can help design a treatment plan for you.

6. Prevention
Wash your hands to avoid the spread of viral diarrhea. To ensure adequate hand washing:
Wash frequently. Wash your hands before and after preparing food. Wash your hands after
handling raw or uncooked meat, going to the bathroom, changing diapers, sneezing,
coughing and blowing your nose.
Soak your hands for at least 20 seconds. After putting soap on your hands, rub them for at
least 20 seconds. It is the time it takes to sing the "happy birthday" completely twice,
approximately.
Use hand sanitizer when you can not wash them. Use an alcohol-based hand sanitizer when
you do not have access to a sink. Apply the hand sanitizer as if it were a lotion and make
sure to cover both the palm and the back of both hands. Use a product that contains at least
60% alcohol.
Vaccination
You can help protect your baby from rotavirus, the most common cause of viral diarrhea in
children, with one of two approved vaccines. Ask your child's doctor about immunizations.
How to prevent traveler's diarrhea
This type of diarrhea often affects people who travel to countries where there are poor
hygiene conditions and contaminated food. To reduce the risk:
Pay attention to what you eat. Eat hot, well-cooked foods. Avoid raw fruits and vegetables
unless you can peel them yourself. Also avoid eating raw or undercooked meats and dairy
products.
Pay attention to what you drink. Drink bottled water, soft drinks, soft drinks, beer or wine
served in its original container. Avoid tap water and ice cubes. Use bottled water even to
brush your teeth. Keep your mouth closed while you shower.
Drinks made with boiled water, such as coffee and tea, are probably safe. Remember that
alcohol and caffeine can aggravate diarrhea and dehydration.
Ask the doctor about antibiotics. If you are traveling to a developing country and plan to
stay for a while, ask your doctor about starting antibiotic treatment before you leave,
especially if your immune system is weakened. In certain cases, taking an antibiotic may
reduce the risk of traveler's diarrhea.

7. Pay attention to the warnings for travelers. The Centers for Disease Control and Prevention
maintains a health website for travelers where warnings about diseases are published in
relation to various countries. If you plan to travel outside of the United States, check the
site for warnings and tips to reduce the risk.
