These growths usually form on sun-exposed skin on the nose, cheeks, ears, and elsewhere on the head and neck.
Symptoms include weakness in the body, loss of appetite, diarrhea, loose or watery stools, stomach cramps, upset stomach, projectile vomiting (uncommon), bloating, excessive gas, and burping (often sulfurous). Symptoms typically develop 9â15 days after exposure, but may occur as early as one day.Symptoms are caused by Giardia organisms infecting the cells of the duodenum and jejunum of the small intestine and blocking nutrient absorption. Most people are asymptomatic; only about a third of infected people exhibit symptoms.If the infection is not treated, these symptoms may last for six weeks or more.ymptoms are caused by Giardia organisms infecting the cells of the duodenum and jejunum of the small intestine and blocking nutrient absorption.
