What are the signs and symptoms of the infection?

Most people who have giardiasis do not have symptoms. When symptoms do occur, they usually include:

abdominal cramping

dehydration

fatigue

gas

loss of appetite

malaise, or a vague feeling of illness

nausea

watery diarrhea

In more severe cases, people can lose weight and children may stop growing. People with weakened defense systems or people with cystic fibrosis can develop more serious problems from the infection.
