Parasites can directly affect the intestines by causing increased or decreased appetite in the infected person. A parasitic infection can cause cravings for sweets or fats, which in turn can lead to weight gain. There are also parasitic infections that can increase or decrease your appetite in connection with the fact that they secrete substances directly in the intestine affecting your appetite and inhibiting your absorption of nutrients.

Parasites such as tapeworms, Cryptosporidium parvum and Blastocystis species can cause loss of appetite and weight loss. A more severe infection with the parasite Giardia lamblia can lead to weight loss by preventing the intestinal absorption of nutrients, fat, lactose, vitamin A and vitamin B12*.
