Before we dive into the changes in appetite, let’s define what appetite is. Simply put, appetite is the desire to eat. It’s regulated by the body’s need for nourishment and can be influenced by external factors such as sight, smell, and thought of food. It’s important to distinguish between appetite and hunger; while hunger is the physiological need for food, appetite is more psychological.

A decrease in appetite can be as simple as feeling less hungry than usual or as complex as a complete aversion to food. There are many reasons why this can happen:

  • Age-related changes: Does appetite decrease with age? Yes, it’s common for older adults to experience a reduced appetite. This can be due to a decrease in physical activity, changes in taste and smell, or the body requiring less energy.
  • Emotional factors: Stress, anxiety, and depression can all lead to a decreased desire to eat. Emotional states have a profound impact on our eating habits.
  • Medical conditions: Certain illnesses, such as infections or chronic diseases, can reduce appetite as the body focuses on fighting off illness rather than on food intake.
  • Medications: Some medications can cause a reduction in appetite as a side effect.

If you find yourself asking, “Why has my appetite decreased?” it may be worth considering these factors and consulting a healthcare professional for a thorough evaluation.
