Difference between Nausea and Hunger

Key Difference: Nausea is a feeling of physical unwellness, usually with the desire to vomit. On the other hand, hunger is a need or compelling desire for food.

Wikipedia defines Nausea as, “a sensation of unease and discomfort in the upper stomach with an involuntary urge to vomit.” The word nausea has been derived from word ‘nausia’, meaning motion sickness. Nausea does not have a specific symptom, which means that it has many possible causes. Nausea basically is a sickness of the stomach that occurs after having food. It especially happens by a strong dislike/disgust or bad feeling that may lead to an impulse to vomit.

Hunger Wikipedia defines hunger as, “the physical sensation of desiring food.” From many years, the international price of food is rising rapidly. The hunger is also suffered by those who all are living in the advanced economies such as Great Britain, the United States, etc. Hunger basically is an indication that one needs food to fill his stomach for a particular period of time. It is not a one time activity, it means one is hungry after a certain period of time and needs to fulfill his physical sensation of desiring food.
