Nicotine suppresses hunger because when it’s taken into the body, it fires these particular neurons called POMC neurons. These neurons are responsible for appetite suppression/satiety (feeling full), so it makes sense that when nicotine enters the body you don’t feel hungry. This might not be completely correct but i learned it in my psychobiology class this semester and i hope it is 🙂
None of these really answer your question.
Nicotine (as well as caffeine, or other stimulants like cocaine) is a stimulant—it triggers the release of *adrenaline*.
Adrenaline is a natural hormone that your body uses to signal that it’s going into high performance mode. Sometimes this is the result of your body’s fight or flight response. Your body prioritizes alertness and response and directs blood flow to the brain rather than the stomach while deprioritizing hunger and other biological functions that can wait for a more relaxed moment.
