Giardiasis Health Article

Giardiasis is an intestinal infection caused by the parasite Giardia. You may become infected by ingesting contaminated food or water. Exposure to the stool of someone who`s infected can also cause infection.

When to Go to the Emergency Room (ER)

Get medical help for severe symptoms that include:

• Diarrhea

• Stomach bloating or fullness

• Nausea or vomiting

• Unplanned weight loss

• Blood in your stool

• Dehydration

What to Expect in the ER

You will be examined and will likely have a stool culture. This checks a sample of your stool for the parasite that causes the disease. If giardiasis is suspected or confirmed, you may be prescribed medication that you take for 5 to 7 days. In many cases, this clears the infection.
