It’s the strangest feeling–you feel hungry, but have no desire to eat. This condition can be short term, or sometimes it can last for longer periods. Either way, it can be frustrating and may even be a sign of underlying health issues. In this article, we’ll tell you everything you need to know about why you might not want to eat, even though you’re hungry–and we’ll let you know when to seek medical attention.
What Does It Mean to Be Hungry Without an Appetite?
Hunger and appetite are related, but aren’t exactly the same thing. Understanding the difference is important.
Hunger “includes a range of feelings that signal the need to eat,” while appetite is “the psychological desire for foods or beverages.”
In other words, hunger is feelings-based. Your body feels hungry. Appetite, on the other hand, is about desire. For example, you’ve planned a special dinner at a restaurant you only visit occasionally. You’re looking forward to eating that meal independent of how hungry you feel at the moment.
That’s why it’s technically possible to feel hungry, but lack an appetite. And not only is it possible, it’s actually surprisingly common.
Common Causes of Loss of Appetite
Some of the causes of loss of appetite might be short-term. If you have the flu or a cold, for example, you might not feel like eating, but those conditions will soon pass. Other causes, though, might be chronic, whether physical, psychological, related to medication use, and so on. If your loss of appetite persists for more than a week, you should consult a healthcare provider.
Short-Term Causes
If you’ve lost your appetite for a few days, don’t fret–there may not be any cause for concern. If you have a short-term illness, like a cold or a flu, you may be experiencing a loss of appetite, a common and normal side effect. Once the illness passes, your appetite will likely return.
Your taste and smell play a role in appetite too. A lack of appetite is expected w. Medications–including some antibiotics, antidepressants, chemotherapy drugs, and opioids– also reduce appetite.
Other reasons for short-term loss of appetite include:
Pain
Anemia (low iron levels)
Migraine
Concussion
If your lack of appetite lasts longer than a few days, reach out to your healthcare provider as it may be due to a chronic condition.
Long-Term Causes
Prolonged periods of lack of appetite (think longer than a week) are concerning. Many diseases, such as diabetes, cancer, and heart failure, and their treatments, are linked with appetite loss.
As people age, their appetite may be reduced or even disappear. Changes to hormones, digestive processes, and the senses that accompany aging affect appetite. Reductions in appetite can be a normal part of the aging process.
Those with dementia may have difficulty remembering whether or not they have eaten. They may not know how to interpret their body’s hunger signals.
While physical factors and medications may contribute to appetite loss, it is also important to consider whether any mental health factors are involved.
Mental Health Factors
Appetite and weight changes can be a component of many mental health disorders. These include:
Grief
Stress
Anxiety
Depression
Eating disorders
