What is it called when you are not feeling hungry?

According to a 2018 study, high levels of the stress hormone cortisol can be linked to decreased appetite. Medically, when you are not feeling hungry, the condition is referred to as anorexia, which is distinct from the eating disorder anorexia nervosa.

Quick Summary

The medical term for not feeling hungry is anorexia, a symptom referring to a general loss of appetite, and is different from the eating disorder anorexia nervosa. A variety of factors, from temporary infections to underlying chronic conditions or psychological issues, can cause it.

Key Points

• Anorexia is the Medical Term: The clinical term for a loss of appetite is anorexia, not to be confused with the eating disorder of the same name.

• Not the Same as Anorexia Nervosa: Anorexia is a symptom where you lack the desire to eat, while anorexia nervosa is a mental health condition involving deliberate food restriction.

• Causes Vary Widely: A lack of hunger can be caused by minor issues like a cold or stress, or more serious conditions like chronic disease, cancer, or side effects from medication.

• Aging is a Factor: As individuals age, a decreased metabolism and changes in taste and smell can contribute to a reduced appetite.

• Seek Medical Advice if Persistent: If a lack of appetite lasts for more than a week, or is accompanied by significant unexplained weight loss or other severe symptoms, consult a doctor.

• Manage with Small Meals: For temporary loss of appetite, eating small, frequent meals of nutrient-dense, palatable foods can be a helpful strategy.

Understanding Anorexia: A Medical Definition

While the term anorexia is commonly associated with the eating disorder anorexia nervosa, its primary medical definition simply refers to a loss or decreased appetite. It is a symptom, not a diagnosis in itself, and can be caused by a wide range of temporary and chronic factors. Many people may experience this intermittently due to minor illnesses or stress, while in some cases, it can signal a more significant underlying health issue. Understanding the difference is crucial, as the appropriate response and treatment depend entirely on the underlying cause.

The Difference Between Anorexia and Anorexia Nervosa

It is important to clearly distinguish between the medical symptom and the psychiatric disorder, as the public use of the term is often conflated with the eating disorder.

Feature	Anorexia (Symptom)	Anorexia Nervosa (Eating Disorder)
Definition	A medical symptom characterized by a general loss of appetite or a lack of desire to eat.	A serious mental health condition where an individual restricts food intake due to an intense fear of gaining weight, even if underweight.
Underlying Cause	A result of another medical issue, a medication side effect, or a psychological state like stress or depression.	A psychological and behavioral disorder driven by body image issues and an obsession with weight control.
Desire to Eat	The individual truly does not feel hungry and may be disinterested in food.	The individual may feel hungry but suppresses the desire to eat out of fear of weight gain.
Treatment Focus	Treatment focuses on resolving the underlying medical condition or cause.	Treatment involves comprehensive psychological counseling and nutritional rehabilitation.

Common Causes of Decreased Appetite

Many different factors can cause a person to feel not hungry. These can be grouped into several categories:

Medical and Physical Conditions

• Infections: Acute illnesses like colds, the flu, or more serious infections (such as pneumonia or gastroenteritis) can temporarily reduce appetite.
• Chronic Diseases: Long-term conditions, including chronic kidney or liver disease, heart failure, and certain types of cancer (e.g., stomach, colon, pancreatic), can lead to a sustained loss of appetite.
• Thyroid Issues: An underactive thyroid (hypothyroidism) can slow down metabolism, which in turn can decrease hunger.
• Gastrointestinal Problems: Issues like constipation, acid reflux (GERD), or inflammatory bowel disease (IBD) can affect appetite.
• Aging: As people age, changes in metabolism, hormone levels, and a diminished sense of taste and smell can contribute to a decreased desire to eat.
• Pregnancy: Hormonal changes, morning sickness, and food aversions, particularly in the first trimester, can cause a loss of appetite.

Psychological and Emotional Factors

• Stress and Anxiety: Both short-term and chronic stress can trigger the release of hormones that suppress appetite.
• Depression: A hallmark symptom of depression is a loss of interest or pleasure in activities, including eating, which can lead to reduced appetite.
• Grief: Significant emotional distress can severely impact appetite.

Medication and Substance-Related Causes

• Prescription Medications: Many drugs list decreased appetite as a side effect, including some antibiotics, opioids, and antidepressants.
• Alcohol and Drug Use: Substance abuse can significantly alter appetite.

When to Seek Medical Attention

While a temporary loss of appetite due to a cold or brief stress is usually not cause for concern, there are instances where medical evaluation is necessary. It is advisable to consult a healthcare provider if:

• The loss of appetite lasts for more than a week.
• You experience significant, unexplained weight loss (more than 10 pounds).
• The decreased appetite is accompanied by other worrying symptoms, such as fever, fatigue, rapid heart rate, or pain.
• You suspect the cause is an underlying medical or mental health condition.
• You cannot keep down food or liquids.

Your healthcare provider may conduct a physical examination and order tests to determine the underlying cause and recommend an appropriate course of action.

Strategies to Manage a Decreased Appetite

Depending on the cause, several strategies can help manage a low appetite and ensure you receive proper nutrition:

1. Eat smaller, more frequent meals: Instead of large meals, try eating several small, nutrient-dense meals or snacks throughout the day. This can feel less overwhelming than facing a large plate of food.
2. Focus on palatable foods: When your appetite is low, focus on foods that are appealing and easy to eat. This might include soups, smoothies, yogurt, or other soft foods.
3. Prioritize protein: Ensure each meal or snack includes a source of protein and healthy fats to keep you satiated and nourished.
4. Stay hydrated: Dehydration can further suppress appetite. Drinking broths, soups, and water can help with both hydration and nutrition.
5. Make eating a social event: Eating with family or friends can make the experience more enjoyable and less stressful.
6. Mild exercise: Light physical activity can sometimes help stimulate appetite.
7. Consult a professional: If the issue persists, speaking with a dietitian can provide personalized guidance on how to maximize nutritional intake.

Conclusion

Not feeling hungry is a symptom known as anorexia, which can have many potential causes ranging from temporary illnesses like the flu to more serious chronic conditions or emotional stress. It is crucial to differentiate this medical symptom from the eating disorder anorexia nervosa, which is a psychological illness. While occasional appetite loss is normal, persistent or severe cases accompanied by significant weight loss or other symptoms warrant a consultation with a healthcare provider. Identifying and treating the root cause is the key to resolving the issue and preventing further complications like malnutrition.
