Increased appetite means you have an excess desire for food.
Considerations
An increased appetite can be a symptom of different diseases. For example, it may be due to certain mental conditions and endocrine gland disorders.
An increased appetite can come and go (intermittent), or it can last for long periods of time (persistent), depending on the cause. It does not always result in weight gain.
The terms "hyperphagia" and "polyphagia" refer to someone who is focused only on eating, or who eats excessively before feeling full.
