Your metabolism is the rate at which you burn off energy from the food you eat. Everybody's metabolism is slightly different, so everybody has slightly different needs when it comes to calories. As a general rule, the smaller and more physically active you are, the faster your metabolism.
Giardiasis is an intestinal infection of man and animals caused by a protozoan parasite Giardia intestinalis (also known as Giardia lamblia). Giardia is a simple one-celled parasitic species; it is not a worm, bacteria or virus. The parasite occurs worldwide and is a common cause of Traveler's Diarrhea in people.
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.
