Anorexia nervosa, commonly referred to as anorexia, is a severe eating disorder that affects millions of people worldwide. It is characterized by an intense fear of gaining weight, leading to self-imposed starvation and an unhealthy obsession with thinness.
The lifetime prevalence of anorexia nervosa is 0.3% to 1%. The disorder is more common in women, but it can affect individuals of all genders, ages, and backgrounds. Early detection is crucial for effective treatment and recovery, so it is essential to be aware of the warning signs of this debilitating condition.
Distinguishing between anorexia and bulimia nervosa is crucial. Both involve body image concerns, but bulimia features binge eating followed by compensatory behaviors like self-induced vomiting or excessive exercise. In contrast, anorexia emphasizes extreme caloric restriction and excessive exercise without binge-purge cycles.
Recognizing these distinctions plays a crucial role in delivering the right treatment and support. Being attentive to the warning signs of anorexia is essential for oneself and loved ones.
Physical Signs of Anorexia
Rapid Weight Loss
One of the most noticeable signs of anorexia is rapid, unexplained weight loss. People with anorexia may lose weight quickly due to extreme caloric restriction or excessive exercise. This rapid weight loss can lead to dangerously low body weight and a multitude of health problems.
Anorexia affects individuals of all sizes, not just those who are extremely thin. A study from the University of California San Francisco revealed that one-third of eating disorder cases were classified as atypical anorexia nervosa, where individuals maintain an average or above-normal weight despite displaying anorexic behaviors. It is crucial to recognize the diverse manifestations of anorexia nervosa, as the disorder can present itself in different ways, necessitating awareness of both typical and atypical warning signs.
Fatigue and Weakness
As the body struggles to function with insufficient nutrients, fatigue, and weakness become increasingly common. People with anorexia may feel constantly tired, have difficulty concentrating, and struggle with everyday activities.
Sensitivity to Cold
Anorexia can cause a person to become sensitive to cold temperatures due to a lack of insulating body fat and poor circulation. They may constantly feel cold, even in warm environments, and wear layers of clothing to stay warm.
Dry Skin and Hair Loss
Malnutrition caused by anorexia can lead to dry, brittle skin and hair. In severe cases, hair may fall out, and the skin may develop a yellowish tint. Fingernails may also become brittle and prone to breakage.

Behavioral Signs of Anorexia
Preoccupation with Food
Anorexia often leads to an unhealthy obsession with food. People with this disorder may spend excessive time thinking about food, planning meals, and researching diet and exercise plans. They may also develop rituals around eating, such as cutting food into small pieces or arranging it in a specific way on their plate.
Despite low energy levels, people with anorexia may engage in excessive exercise to burn calories and lose weight. They may prioritize exercise over other activities, even when injured or sick, and experience guilt and anxiety if they miss a workout.
Withdrawal from Social Activities
Individuals with anorexia may become increasingly isolated as they withdraw from social activities and events, especially those involving food. This isolation can exacerbate feelings of loneliness and depression, further reinforcing the eating disorder.
Ritualistic Eating Habits
People with anorexia may develop strange eating habits, such as consuming only certain types of food, eating in a particular order, or using specific utensils. They may also avoid eating in front of others, claiming they have already eaten or are not hungry.
Emotional Signs of Anorexia
Anorexia can cause significant mood swings due to hormonal imbalances and malnutrition. People with this disorder may experience irritability, agitation, and moodiness, making it difficult for them to maintain healthy relationships with friends and family.
A hallmark of anorexia is an intense dissatisfaction with one's body and a distorted self-image. People with this disorder often have low self-esteem and may constantly criticize their appearance, even when they are dangerously underweight.
Depression and Anxiety
Anorexia is often accompanied by depression and anxiety. The constant fear of gaining weight and the isolation resulting from the disorder can contribute to feelings of sadness, hopelessness, and chronic worry. According to the National Eating Disorders Association, nearly half, ranging from 48% to 51%, of individuals diagnosed with anorexia nervosa also experience co-occurring anxiety disorders.
Effects of Anorexia Symptoms
The symptoms of anorexia can have a significant impact on an individual's physical, emotional, and social well-being. Here, we will explore some of the consequences that may arise due to anorexia symptoms.
- Malnutrition: As the body struggles to function with inadequate nutrients, it may lead to various health complications, including weakened immune function, anemia, and hormonal imbalances.
- Organ damage: Prolonged anorexia can result in damage to vital organs such as the heart, kidneys, and liver.
- Osteoporosis: Lack of essential nutrients may lead to weakened bones and osteoporosis, increasing the risk of fractures.
- Growth and development issues: Anorexia during adolescence can disrupt growth and lead to lasting developmental problems.
- Depression and anxiety: The stress and isolation caused by anorexia can contribute to the development of depression and anxiety disorders.
- Cognitive impairment: Malnutrition and constant preoccupation with food and weight can impair concentration and cognitive function.
- Self-esteem issues: People with anorexia often suffer from low self-esteem and a distorted self-image, which can further exacerbate the disorder.
- Relationship strain: Anorexia symptoms can create tension and strain in relationships with friends and family members as the individual becomes increasingly withdrawn and irritable.
- Academic and work performance: The cognitive and emotional effects of anorexia can negatively impact a person's performance at school or work, leading to decreased productivity and achievement.
