What is diarrhea?

Diarrhea is an increase in the frequency, amount or water content of bowel movements. It is a
frequent problem for people with HIV/AIDS (PHAs) and may be caused by several factors. If
diarrhea continues for more than a few days, it can cause serious problems.
The most serious complication resulting from diarrhea is dehydration. When you have diarrhea,
your body loses both water and important minerals necessary for normal functions (such as
sodium and potassium). If diarrhea continues for more than a few weeks, it will cause poor
absorption of many nutrients. This can lead to weight loss (wasting).

What causes diarrhea?

The most common causes of diarrhea in PHAs include:
• infections of the stomach or bowel
• inflammation of the bowel caused by HIV
• certain medications used to treat HIV or related conditions

Infections and diarrhea

Many germs – bacteria, parasites, fungi or virus – can cause infections that lead to diarrhea.
Some common ones that affect PHAs include the following:
• parasites such as Cryptosporidium, Giardia and Entamoeba
• viruses such as CMV (cytomegalovirus)
• fungi such as yeast or Candida
• bacteria such as MAC (Mycobacterium avium complex) and Salmonella
There are treatments available for most of these infections. Because combination therapy used
to treat HIV strengthens the immune system, PHAs who take this treatment are less likely to
develop these infections.

Diarrhea caused by HIV disease

HIV affects the normal working of the stomach and bowels. As a result, the stomach and bowels
cannot digest food and absorb nutrients properly. This often causes diarrhea.

Diarrhea caused by medications

Many HIV medications can cause diarrhea as a side effect. The most common ones to do so are
nelfinavir (Viracept), ritonavir (Norvir), saquinavir (Fortovase) and the original formulation of ddI
(Videx), though almost all of them can. Drugs used to treat complications of HIV, such as ganciclovir

(Cytovene,Valcyte) and interferon alpha (Intron-A, Pegetron, Pegasys), can often cause diarrhea as
well. Sometimes, taking antibiotics (such as Septra and penicillin) can kill off the good bacteria
in your gut and lead to an overgrowth of other germs, causing diarrhea.

Other causes of diarrhea

In addition, people who are lactose intolerant and have problems digesting milk or dairy products
may have diarrhea if they eat or drink milk or dairy products.
Diarrhea can also be triggered or worsened by increased emotional stress.

• Drink lots of fluids:

With diarrhea, your body loses a large amount of water. Drink plenty of
clear fluids to replace the loss.

• Change what you eat:

~Avoid: all dairy products; greasy, fried and fatty food; spicy food; caffeine (found in coffee,
chocolate, tea and pop); apple juice; whole wheat bread; corn
~Eat more: bananas; white rice; congee or noodles; cereal; boiled eggs; oatmeal; mashed
potatoes; yams and squash; toasted white bread; crackers; yogurt

• Nutritional supplements and complementary therapies:

~A high fibre diet or fibre supplements such as Metamucil can add bulk and reduce diarrhea.
~Peppermint, nutmeg and ginger are believed to help with digestive problems. Peppermint
or ginger tea or ginger ale may be good sources of clear fluids.
~Acidophilus is a supplement that contains friendly bacteria. Some PHAs take supplements
of friendly bacteria to help prevent diarrhea that can occur when antibiotics are used.
~Calcium supplements may be effective in reducing diarrhea caused by medications, such as
nelfinavir (Viracept).

• Medications:

Different medications are used to treat different types of diarrhea.
~For diarrhea caused by some bacteria or parasites, you may need special antibiotics to kill
these germs before the diarrhea can be brought under control (for example, Humatin can
be used to treat diarrhea caused by the parasite Cryptosporidium).
~For other diarrhea, medication that slows down movement in the intestine may be effective.
These can include over-the-counter or prescription drugs such as Imodium, Kaopectate,
Pepto-Bismol and Lomotil.

If your diarrhea does not get better in a few days, or if there is also fever or blood in the stool,
consult your doctor right away to test for common causes of diarrhea that can be treated.
