Poor appetite or unexplained weight loss that occurs with gas, burping, or bloating

Many things can cause you to lose your appetite, not all of which are serious. If you are not hungry, you may naturally eat less and lose weight.

Possible causes of poor appetite include:

  • The effects of stress or an emotional situation.
  • The side effects of a medication.
  • A mental health problem, such as anxiety or depression.
  • A problem with the digestive tract, such as an irritation, inflammation, infection, or a digestive disorder.
  • Cancer.
