Signs and symptoms may vary and can last for 1 to 2 weeks or longer. In some cases, people infected with <em>Giardia<\/em> have no symptoms. Acute symptoms include: diarrhea, gas, greasy stools that tend to float, stomach or abdominal cramps, upset stomach or nausea\/vomiting, and dehydration (loss of fluids). Other, less common symptoms include itchy skin, hives, and swelling of the eye and joints. Sometimes, the symptoms of giardiasis might seem to resolve, only to come back again after several days or weeks. Giardiasis can cause weight loss and failure to absorb fat, lactose, vitamin A and vitamin B12. In children, severe giardiasis might delay physical and mental growth, slow development, and cause malnutrition<\/p>\n<p><a href=\"https:\/\/www.cdc.gov\/parasites\/giardia\/pathogen.html\" target=\"_blank\" rel=\"noopener noreferrer\">Giardia Life Cycle<\/a><\/p>\n<p>The size of the <em>Giardia<\/em> cyst is approximately 8 to 14 um; whereas, the <em>Crytosporidium<\/em> oocysts are usually 4 to 6 microns in diameter.
