Which symptoms are commonly associated with Giardia lambia infection?

Giardia lamblia infection, known as giardiasis, is characterized by gastrointestinal symptoms. The correct choice highlights the typical symptoms of this infection, including smelly diarrhea and abdominal cramps. This occurs because the parasite disrupts the normal functioning of the intestines, leading to malabsorption and resulting in foul-smelling, non-bloody diarrhea.

When someone is infected with Giardia lamblia, they may also experience symptoms like bloating, gas, and fatigue. While some individuals may remain asymptomatic, the most common presentation involves the gastrointestinal issues mentioned. The presence of cramping aligns with the inflammatory response resulting from the infection and irritation of the intestinal lining.

The other options present symptoms that are not typical for giardiasis. Headaches and chills are more associated with infections like viral gastroenteritis or other illnesses rather than giardiasis itself. Severe abdominal pain and fever could be more indicative of conditions such as appendicitis or other serious infections, and while some people may not show any symptoms at all, the most recognized symptoms for establishing a diagnosis revolve around diarrhea and cramping.
