evidence: Toxoplasmosis is caused by an infection with the parasite Toxoplasma gondii. This parasite is most commonly found in contaminated food (especially raw and undercooked meat), but it can also be found in cat feces. Most T. gondii infections in people with healthy immune systems are asymptomatic and resolve on their own within a few weeks or months. Ghrelin is a hormone produced by the stomach and often called the “hunger hormone”. There is currently no evidence supporting an association between toxoplasmosis and increased ghrelin hormone levels.
