When most people think about Avoidant/Restrictive Food Intake Disorder (ARFID), they picture children or adolescents who are extremely picky eaters. But the truth is that ARFID isn’t limited to childhood—it can develop later in life, even in adults who once had no issues with food variety. As research on eating disorders continues to grow, clinicians are seeing more adults struggling with ARFID-like symptoms, including fear of choking, sensory sensitivities, and severe restriction of food types that lead to significant weight loss and nutritional deficiencies.
At Oasis Eating Disorders Recovery, our eating disorders treatment center in Fresno, we help individuals of all ages understand the roots of ARFID and learn to rebuild a balanced, safe relationship with food. If you’ve found yourself becoming increasingly anxious, avoidant, or restrictive around eating, you may be facing symptoms of ARFID—and it’s important to know that recovery is entirely possible.
What Is ARFID?
Avoidant/Restrictive Food Intake Disorder, or ARFID, is an eating disorder recognized in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). Unlike conditions such as anorexia nervosa or bulimia nervosa, ARFID isn’t about body image or fear of gaining weight. Instead, it’s defined by extreme restriction of food intake due to:
- Lack of interest in food or eating
- Sensory sensitivities (like taste, texture, or smell aversions)
- Fear of negative consequences such as choking, vomiting, or allergic reactions
Over time, these restrictive patterns can cause malnutrition, low body weight, fatigue, and serious health complications, including osteoporosis and weakened immunity.
While ARFID often begins in childhood or adolescence, more recent studies—including findings from the Journal of Eating Disorders—show that adults can also meet diagnostic criteria, particularly when symptoms were mild earlier in life and intensified later due to stress, trauma, illness, or anxiety disorders.
How ARFID Differs From “Picky Eating”
It’s easy to confuse ARFID with picky eating, but they’re very different in severity and impact. Picky eaters may have preferences or dislikes but still maintain a balanced diet and adequate nutrition. In contrast, individuals with ARFID experience intense distress or avoidance that interferes with daily life, social interactions, and physical health.
For example, someone with ARFID may:
- Eat only a few “safe” foods and refuse to try new ones
- Experience panic or nausea at mealtimes
- Avoid social events involving food
- Lose weight or develop nutritional deficiencies despite no desire to be thin
When left untreated, ARFID can lead to chronic health problems, emotional distress, and a reduced quality of life.
Can Adults Develop ARFID Later in Life?
Yes—and it’s more common than many people realize. While ARFID has traditionally been diagnosed in adolescents, clinicians are increasingly identifying adult-onset ARFID in people who previously had normal eating habits.
Here are some reasons this can occur:
1. Traumatic Food Experiences
A single distressing event, like choking, vomiting, or a severe allergic reaction, can cause lingering anxiety about eating. Adults who develop this fear may begin avoiding entire food groups or textures associated with the event, eventually leading to ARFID.
2. Sensory Changes or Health Conditions
Chronic gastrointestinal issues, GERD, or irritable bowel syndrome can make eating uncomfortable and trigger food avoidance. Similarly, neurological conditions, hormonal changes, or medication side effects may heighten sensory sensitivities, causing certain foods to feel intolerable.
3. Co-Occurring Mental Health Conditions
Adults with anxiety disorders, OCD, or autism spectrum disorder (ASD) are at greater risk for developing ARFID later in life. In these cases, restrictive eating may stem from perfectionism, fear of contamination, or rigid thinking patterns that make expanding food variety feel overwhelming.
4. Life Transitions and Stress
Major changes—like moving, pregnancy, illness, or loss—can disrupt eating habits and trigger avoidance behaviors in people already vulnerable to anxiety or sensory stress.
5. Autism and ADHD
Adults who are later diagnosed with autism or ADHD often realize their eating challenges fit the profile of ARFID. For neurodivergent individuals, sensory sensitivities and executive functioning challenges can make meal preparation, grocery shopping, or trying new foods particularly difficult.
Common Symptoms of ARFID in Adults
While symptoms vary, adults with ARFID often experience:
- Extreme selectivity about food textures, colors, or temperatures
- Fear of choking, vomiting, or feeling sick
- Avoidance of eating in social settings
- Weight loss or inability to gain weight
- Nutritional deficiencies (low iron, calcium, or vitamin levels)
- Low energy, dizziness, or fatigue
- Anxiety or panic attacks at mealtimes
- Reliance on supplements or liquid nutrition for calories
- Declining physical health despite normal appetite levels
These symptoms can significantly disrupt daily life, work, and relationships—especially when a person hides or downplays their eating challenges out of shame or confusion.
Diagnosing ARFID in Adulthood
Because adult-onset ARFID is less widely recognized, it’s often misdiagnosed as anxiety, depression, or general picky eating. A proper ARFID diagnosis involves evaluation by a mental health professional, dietitian, or psychiatrist familiar with eating disorders.
The assessment may include:
- Medical screening to rule out physical causes (gastrointestinal or allergic conditions)
- Psychological evaluation for anxiety, trauma, or sensory sensitivities
- Review of eating patterns and weight history
- Measurement of nutritional markers (iron, B12, calcium, etc.)
Early diagnosis is crucial to prevent malnutrition, osteoporosis, and chronic health complications.
Living With ARFID: The Emotional Side
Beyond the physical symptoms, ARFID can deeply affect self-esteem and emotional well-being. Many adults feel embarrassed about their restrictive eating or fear judgment from others. Over time, this can lead to social isolation, guilt, or hopelessness—especially when friends or family don’t understand that ARFID is a serious eating disorder, not a “choice.”
If your loved one struggles with selective eating or food-related anxiety, approach the topic with compassion. Avoid pressure or criticism—instead, focus on offering understanding, support, and encouragement to seek professional care.
When to Seek Professional Help
You should reach out for professional support if:
- Eating is causing anxiety, panic, or distress
- You’re losing or gaining weight unexpectedly
- Nutritional supplements or a narrow diet are affecting your physical health
- You’ve stopped attending social gatherings due to mealtime fears
- You suspect co-occurring conditions like autism, ADHD, or anxiety disorder
Treatment can help you rebuild not just your eating habits, but your confidence, energy, and quality of life.
