"GETTING BETTER TOGETHER"

Diarrhea

Everyone occasionally has diarrhea — loose, watery and possibly more-frequent bowel movements.

In most cases, diarrhea lasts a couple of days. But when diarrhea lasts for weeks, it can indicate a serious disorder for which you may need to see your doctor. Most cases however may be treated at home or by visiting your Polyclinic or general practitioner without the need to visit Accident and Emergency.

Symptoms:

Signs and symptoms associated with diarrhea may include:

  • Loose, watery stools
  • Abdominal cramps
  • Abdominal pain
  • Fever
  • Blood in the stool
  • Bloating
  • Nausea
  • Urgent need to have a bowel movement

When to see a doctor

If you’re an adult, see your doctor if:

  • Your diarrhea persists beyond two days
  • You become dehydrated
  • You have severe abdominal or rectal pain
  • You have bloody or black stools
  • You have a fever above 102 F (39 C)

In children, particularly young children, diarrhea can quickly lead to dehydration. Call your doctor if your child’s diarrhea doesn’t improve within 24 hours or if your baby:

  • Becomes dehydrated
  • Has a fever above 102 F (39 C)
  • Has bloody or black stools

Causes:

A number of diseases and conditions can cause diarrhea, including

  • Viruses. Viruses that can cause diarrhea include Norwalk virus, cytomegalovirus and viral hepatitis. Rotavirus is a common cause of acute childhood diarrhea.
  • Bacteria and parasites. Contaminated food or water can transmit bacteria and parasites to your body. Parasites such as Giardia lamblia and cryptosporidium can cause diarrhea.Common bacterial causes of diarrhea include campylobacter, salmonella, shigella and Escherichia coli. When traveling in developing countries, diarrhea caused by bacteria and parasites is often called traveler’s diarrhea. Clostridium difficile infection can occur, especially after a course of antibiotics.
  • Medications. Many medications, such as antibiotics, can cause diarrhea. Antibiotics destroy both good and bad bacteria, which can disturb the natural balance of bacteria in your intestines. Other drugs that cause diarrhea are cancer drugs and antacids with magnesium.
  • Lactose intolerance. Lactose is a sugar found in milk and other dairy products. People who have difficulty digesting lactose have diarrhea after eating dairy products.
  • Fructose. Fructose, a sugar found naturally in fruits and honey and added as a sweetener to some beverages, can cause diarrhea in people who have trouble digesting it.
  • Artificial sweeteners. Sorbitol and mannitol, artificial sweeteners found in chewing gum and other sugar-free products, can cause diarrhea in some otherwise healthy people.
  • Surgery. Some people have diarrhea after undergoing abdominal surgery or gallbladder removal surgery.
  • Other digestive disorders. Chronic diarrhea has a number of other causes, such as Crohn’s disease, ulcerative colitis, celiac disease, microscopic colitis and irritable bowel syndrome.

Complications:

Diarrhea can cause dehydration, which can be life-threatening if untreated. Dehydration is particularly dangerous in children, older adults and those with weakened immune systems.

If you have signs of serious dehydration, seek medical help.

Indications of dehydration in adults

  • Excessive thirst
  • Dry mouth or skin
  • Little or no urination
  • Weakness, dizziness or lightheadedness
  • Fatigue
  • Dark-colored urine

Indications of dehydration in infants and young children

  • Not having a wet diaper in three or more hours
  • Dry mouth and tongue
  • Fever above 102 F (39 C)
  • Crying without tears
  • Drowsiness, unresponsiveness or irritability
  • Sunken appearance to the abdomen, eyes or cheeks

Prevention:

  • Wash frequently. Wash your hands before and after preparing food. Wash your hands after handling uncooked meat, using the toilet, changing diapers, sneezing, coughing and blowing your nose.
  • Lather with soap for at least 20 seconds. After putting soap on your hands, rub your hands together for at least 20 seconds. This is about as long as it takes to sing “Happy Birthday” twice through.
  • Use hand sanitizer when washing isn’t possible. Use an alcohol-based hand sanitizer when you can’t get to a sink. Apply the hand sanitizer as you would hand lotion, making sure to cover the fronts and backs of both hands. Use a product that contains at least 60 percent alcohol.
  • Watch what you eat. Eat hot, well-cooked foods. Avoid raw fruits and vegetables unless you can peel them yourself. Also avoid raw or undercooked meats and dairy foods.
  • Watch what you drink. Drink bottled water, soda, beer or wine served in its original container. Avoid tap water and ice cubes. Use bottled water even for brushing your teeth. Keep your mouth closed while you shower.Beverages made with boiled water, such as coffee and tea, are probably safe. Remember that alcohol and caffeine can aggravate diarrhea and dehydration.
  • Ask your doctor about antibiotics. If you’re traveling to a developing country for an extended time, ask your doctor about starting antibiotics before you go, especially if you have a weakened immune system. In certain cases, taking an antibiotic might reduce your risk of traveler’s diarrhea.

Vaccination

You can help protect your infant from rotavirus, the most common cause of viral diarrhea in children, with one of two approved vaccines. Ask your baby’s doctor about having your baby vaccinated.

Home Remedies:

Most diarrhea cases clear up on their own within a few days. To help you cope with your signs and symptoms until the diarrhea goes away, try to:

  • Drink plenty of clear liquids, including water, broths and juices. Avoid caffeine and alcohol.
  • Add semisolid and low-fiber foods gradually as your bowel movements return to normal. Try soda crackers, toast, eggs, rice or chicken.
  • Avoid certain foods such as dairy products, fatty foods, high-fiber foods or highly seasoned foods for a few days.
  • Ask about anti-diarrheal medications. Over-the-counter (OTC) anti-diarrheal medications, such as loperamide (Imodium A-D) and bismuth subsalicylate (Pepto-Bismol), might help reduce the number of watery bowel movements and control severe symptoms.Certain medical conditions and infections — bacterial and parasitic — can be worsened by these medications because they prevent your body from getting rid of what’s causing the diarrhea. Also, these drugs aren’t always safe for children. Check with your doctor before taking these medications or giving them to a child.
