If a human gets Giardia, they may experience a range of signs and symptoms. These typically appear one to three weeks after exposure to the parasite. One of the most common symptoms is watery diarrhea, which can sometimes have a foul smell. The diarrhea may alternate with soft, greasy stools.
In addition to diarrhea, individuals with Giardia infection may also experience fatigue. This can be a result of the body’s immune response to the parasite, as well as the impact of diarrhea on nutrient absorption. The constant loss of fluids and nutrients can leave a person feeling tired and weak.
Stomach cramps and bloating are another common symptom of Giardia infection. The parasite can cause irritation and inflammation in the intestines, leading to discomfort and pain in the abdominal area. Bloating, or a feeling of fullness in the stomach, is also commonly reported.
Other possible symptoms of Giardia infection include nausea, vomiting, and weight loss. These symptoms can vary from person to person and may not be present in all cases. Some individuals may also experience a low-grade fever or have a decreased appetite.
It is worth noting that not everyone who becomes infected with Giardia will develop symptoms. Some individuals may be asymptomatic carriers, meaning they carry the parasite but do not show any signs of illness. However, these individuals can still spread the infection to others.
If you suspect you have Giardia or are experiencing these symptoms, it is important to seek medical attention. A healthcare professional can perform tests to confirm the diagnosis and recommend appropriate treatment. Treatment typically involves anti-parasitic medications to eliminate the infection.
Giardia infection in humans can lead to a range of symptoms including watery diarrhea, fatigue, stomach cramps, bloating, nausea, vomiting, and weight loss. It is important to seek medical attention for proper diagnosis and treatment.
