You may forget to eat and realize later on that you’ve skipped one or two meals. You may even start losing weight without making an effort to diet or exercise.

What Causes Loss of Appetite?

There are countless reasons for loss of appetite. Usually, your appetite will come back once you’ve addressed the root cause of your appetite loss.

  • Chronic conditions known to decrease appetite include liver disease, kidney disease, and cancer.
  • Pain conditions including fibromyalgia and arthritis

Depression can lead to loss of interest or pleasure in ordinary activities, including cooking, eating, and socializing with friends and family at restaurants. Depression also causes fatigue and low energy, making cooking and eating seem like major, energy-draining tasks. Anxiety, physical pain, and feelings of sadness and hopelessness can also lead to appetite loss.

Some medications used to treat depression and bipolar disorder cause appetite loss as a side effect, along with spikes in energy and nausea that may also contribute to appetite loss.

What Is the Best Loss of Appetite Treatment?

If you suffer from an acute illness such as influenza or the common cold, your appetite will gradually return as you start feeling better.

If you have a chronic illness or pain condition such as cancer, your medical team or caregiver may try various methods to stimulate your appetite, such as giving you nutritious fruit smoothies or small snacks several times per day instead of three large meals.

The best treatments for appetite loss are those that address the underlying causes of your reduced appetite. If the cause of your appetite loss has not been identified, your doctor may run a series of diagnostic tests, including blood work, ultrasound, X-ray, and CT scan. You may also be tested for pregnancy and HIV/AIDS.

Medications approved by the FDA for treating reduced appetite include megestrol acetate, oxandrolone, and dronabinol. These medications can stimulate your appetite to help you eat more. If you are currently using medications that suppress appetite, such as antidepressants, your doctor may discuss your options for other treatments that won’t cause appetite loss.

If your appetite loss stems from a mental or behavioral health disorder, your doctor may refer you to a psychiatrist, psychologist, or addiction treatment center to receive specialized treatment.


How Can I Increase Appetite on My Own?

You may be able to stimulate your appetite by trying new foods, meals, and cooking methods that motivate you to start eating again. Ways to try increasing your appetite include:

  • Use various spices and seasonings that enhance the flavor of meals, including coriander, ginger, paprika, rosemary, and thyme.
  • Growing and eating your herbs and produce, such as basil, peppermint, sweet peppers, and of seniors eating together
  • Consume a higher amount of your favorite foods, even if it causes you to miss out on critical food groups for a short period, as the goal is for you to start eating again. For example, a bowl of yogurt or a bean burrito can suffice on most days of the week.
  • Eat a higher amount of small, calorie-dense meals or snacks throughout the day instead of eating three large meals.
  • Eat only highly nutritious foods even if those meals are simple, such as a bowl of seasoned quinoa. That helps ensure you are consuming essential nutrients when you do feel like eating.
  • Try new restaurants or recipes for meals that contain ingredients that sound appetizing. For example, if you want citrus-flavored chicken, you can look up recipes for Mexican marinades or Asian dishes made with limes or oranges that will help fulfill your craving.
  • Making plans to eat with friends or relatives could make eating more enjoyable, and your loved ones can hold you accountable for eating.
