Are You Suffering From an Eating Disorder? – Red Flag Signs

Ask yourself these questions. The more “yes” answers the more likely you are suffering from an eating disorder.

  • Do you feel fat even though you’re not?
  • Do you lie about how much you eat?
  • Are others concerned about your eating habits?
  • Do you feel powerful when you go without food, over-exercise, or purge?
  • Do you base your self-worth on your body weight?

Other Red Flags to Consider

Look at these questions.

  • Do you vomit or take laxatives to control your weight?
  • Do you starve yourself?
  • Do you eat until you feel sick?
  • Do you think about food all the time?
  • Do you feel disgusted or ashamed after eating?
  • Do you eat privately so no one will see you eating?
  • Do you weigh yourself several times a day?
Did you answer 'yes' to some of these questions? If so, you may have an eating disorder.

What Are Eating Disorders?

An eating disorder is a condition that leads people to overeat, starve themselves, or adopt other unhealthy behaviors. Many factors can play a role in the causes of eating disorders, including biology, emotional health, societal expectations and trauma.

In the U.S., up to 24 million people, or 8% of the population, suffer from an eating disorder, most often women between the ages of 12 and 35. However, many cases are likely not to be reported.

There are three main types of eating disorders: anorexia, bulimia, and binge eating disorder. People with an eating disorder tend to be perfectionists, usually “feel fat”, and see themselves as overweight, even despite life-threatening semi-starvation. An intense fear of gaining weight may consume them. Eating disorders frequently coexist with other illnesses such as depression, substance abuse, or anxiety disorders.

What is Anorexia Nervosa?

Anorexia nervosa is an eating disorder where the person severely cuts down on the amount of food they eat, resulting in dramatic weight loss. In addition, excessive exercise, diet pills, vomiting after eating, laxatives, enemas and diuretics can be used to decrease weight.

Most often the person has an intense fear of becoming fat and has a distorted view of their body image even if they are already underweight. They will typically deny there is a problem even when it is evident to all that it is serious. They can undergo quite sudden personality and mood swings.

Food is the Enemy

Probably the biggest single symptom of anorexia is anxiety around food. This can manifest itself by the person skipping meals, cutting out previously eaten food types and being secretive about eating. They may portion their food carefully, eat very small amounts of restricted foods, count calories, or weigh food before eating it.

People with this condition may simply move food around the plate without actually eating anything. When challenged about food the response is often very confrontational and aggressive.

Anorexia - Red Flag Symptoms

Signs and symptoms of anorexia may include:

  • Extremely low body weight
  • Severe food restriction
  • Relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight
  • Intense fear of gaining weight
  • Distorted body image and self-esteem that is heavily influenced by perceptions of body weight and shape, or a denial of the seriousness of low body weight
  • Lack of menstruation among girls and women.

What Are the Physical Effects of Anorexia?

Severe calorie restriction has dire physical effects. When your body doesn’t get the fuel it needs to function normally, it goes into starvation mode. Some of the physical effects include:

  • Brittle hair, nails, or yellowing skin
  • Fine hair growth all over the body
  • Cold sensitivity
  • Constipation
  • Loss of menstrual periods or infertility
  • Lethargy, sluggishness, or feeling tired all the time
  • Long-term problems can include anemia, thinning bones, damage to the heart, organ failure, and death.

What is Bulimia Nervosa?

Bulimia nervosa is an eating disorder characterized by frequent episodes of binge eating, followed by frantic efforts to avoid gaining weight such as forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors.

Unlike anorexia nervosa, people with bulimia nervosa usually maintain a normal weight, while some are slightly overweight, but sufferers have an intense fear of gaining weight and are unhappy about their body size. The binge-purge cycle may happen several times a day or several times a week. It is often done in secret because of feelings of shame, disgust and embarrassment.

Bulimia: All or Nothing Signs of Binge Eating

  • Lack of control over eating and eating until the point of physical discomfort and pain.
  • Secrecy surrounding eating. Late-night kitchen visits; unexpected food runs; wanting to eat in privacy.
  • Eating large amounts of food with no change in weight.
  • Disappearance of food, empty wrappers, or hidden stashes of junk food.
  • Alternating between overeating and fasting, and rarely eats a normal meals. With bulimia, it’s all-or-nothing when it comes to food.

Bulimia: Signs Of Purging

Signs of purging may include:

  • Disappearing after meals for a bathroom trip to purge, and may run water to hide sounds of vomiting.
  • Using laxatives, diuretics, or enemas after eating; diet pills to curb appetite; sauna use to “sweat out” water weight.
  • The bathroom or the person may smell like vomit; they may try to cover up the smell with mouthwash, perfume, air freshener, gum, or mints.
  • Working out strenuously, especially after eating.

Bulimia – What Are The Physical Signs Of Bulimia?

  • Calluses or scars from sticking fingers down the throat to induce vomiting.
  • Sore throat, tooth decay and bad breath caused by excessive vomiting
  • Swollen salivary glands making the face rounder
  • Poor skin condition
  • Normal weight or slightly overweight; being underweight while purging might indicate a purging type of anorexia
  • Frequent fluctuations in weight
  • Irregular periods

The Serious Effects of Bulimia

The most dangerous side effect of bulimia is dehydration due to purging.

Vomiting, laxatives, and diuretics can cause electrolyte imbalances in the body, most commonly in the form of low potassium levels. Low potassium levels trigger a wide range of symptoms ranging from lethargy and cloudy thinking to irregular heartbeat and death. Chronically low levels of potassium can also result in kidney failure.

What is Binge Eating Disorder?

Compulsive overeating, consuming huge amounts of food, and basically feeling out of control characterize binge eating disorder. Binge eaters may eat when they’re not hungry and continue to gorge after they’re full. Food may not be fulfilling or even taste good, for that matter.

People with binge eating disorder do not purge; therefore, they often gain weight and may be at risk for high blood pressure, heart disease, and the other risks of obesity. To make matters worse, people with binge eating disorder suffer emotional distress and guilt, which can compound their binge eating habits.

Binge Eating Disorder – Red Flag Signs

  • An inability to stop eating or control what you’re eating
  • Rapidly eating large amounts of food
  • Eating even when you're full
  • Hiding or stockpiling food to eat later in secret
  • Eating normally around others, but gorging when you’re alone
  • Eating continuously throughout the day, with no planned mealtimes

The Effects of Binge Eating

People with binge eating disorder report more health issues, stress, insomnia, and suicidal thoughts than people without an eating disorder. Depression, anxiety, and substance abuse are common. The most prominent effect of binge eating disorder is weight gain.

Over time, binge eating usually leads to obesity. Obesity, in turn, causes numerous medical complications, including:

  • Type 2 diabetes
  • Heart disease
  • High blood pressure
  • High cholesterol
  • Higher risk for cancer
  • Osteoarthritis.

Where To Look For Help

If you or a loved one is struggling with an eating disorder, don't hesitate to talk about it. Voice your concerns respectfully, avoiding guilt or blame. If you need help, consider asking for it. Focus on the specific behaviors that worry you. Encourage the loved one to get help, or seek it for yourself with a friend's help. Taking the first step is always the hardest.

The road to recovery can begin once you realize help is there. Initially you could seek help from a doctor, school nurse or counselor.

What’s Treatment Like?

The exact treatment needs of someone struggling with an eating disorder will vary according to the individual. Treatment usually involves a team of health professionals and might include a family doctor, a psychologist, a nutritionist, a social worker, and a psychiatrist.

Treatment may involve a combination of drug therapy, nutritional counseling, and talk therapy. Therefore, it is important that a health care professional coordinate any treatment plan.

Help For Eating Disorders

The first step in treating anorexia nervosa is to assist patients with regaining weight to a healthy level. Some patients may need to be hospitalized to treat problems caused by malnutrition. Psychotherapy is an evidence-based treatment that is used. No medicines are FDA-approved to treat anorexia as they have limited effect. However, antidepressants or other medications can help treat related disorders such as depression or anxiety.

For patients with bulimia, interrupting the binge-purge cycle is the key. Research has shown that antidepressants including fluoxetine (Prozac) and imipramine (Tofranil) can help break the cycle, prevent relapses and may also help with depression or anxiety. Prozac is specifically FDA-approved to treat bulimia. Combining psychotherapy with antidepressants may be the most effective treatment for bulimia.

For patients with binge eating disorder it is important to help them interrupt and stop binges. Lisdexamfetamine (Vyvanse) was approved for binge eating disorder in February 2015. Prozac has also been used off-label, meaning it is not specifically approved for this use, but may be prescribed by your doctor.

More Help for Eating Disorders

However, restoring a person to normal weight only addresses half the problem. Learning to cope and having a reliable support system is key.

Counseling, either individual, group or family, is also needed to help patients understand the thoughts, emotions and behaviors that trigger these disorders.

Nutritional counseling and therapy can also help the person establish healthy eating habits and develop a better relationship with food and eating.

Family members and friends should also keep any eye for any signs or symptoms of these eating disorders.

Who Else Can Help?

While family and friends can be a huge help in providing support, you may also want to join an eating disorder support group. They provide a safe environment where you can talk freely about your eating disorder and get advice.

You can also find online support groups for eating disorders. The following organizations can provide reliable information on eating disorders:
