Because Rumination Disorder is involuntary, it is difficult to prevent its consequences without receiving medical treatment. Some physical consequences of the disorder are:

* Malnutrition
* Unintended and/or unhealthy weight loss
* Bad breath
* Damage to teeth by regurgitated stomach acid 

Grinnell College

Rumination disorder is an eating disorder where an individual unconsciously regurgitates food immediately after eating. This eating disorder is rare and is most common in children.

Rumination Disorder

Eating disorders, particularly conditions like bulimia nervosa and anorexia nervosa, are associated with a wide range of severe and adverse health consequences.

The consequences of Pica vary greatly as the non-food items ingested by those afflicted with Pica vary in their ingestability and toxicity. Depedning on what is eaten (ex: ice), Pica may even be harmless. However, some common and severe consequences are listed below:

* Damage to teeth by ingested matter
* Blockage of the digestive tract by ingested matter
* Contraction of illness/disease from ingested matter
* Death from toxic ingested matter

Pica: Consequences

Because binge eating disorder involves overconsumption of food, the consequences of binge eating disorder differ from other eating disorders, whose consequences occur due to lack of/restriction of food. Some possible consequences of binge eating disorder are:
* Obesity
* Type 2 Diabetes
* Heart disease
* Joint problems
* Gastroesophageal reflux disease (GERD)

Binge Eating Disorder: Consequences

Physical consequences of ARFID vary due to an individual's age. Common symptoms are:

-  Gastroenterological distress
- Inadequate or slowed growth
- Low weight
- Decreased appetite
- Abdominal pain when eating
- Nutrient deficiencies

Avoidant/Restrictive Food Intake Disorder (ARFID): Consequences

Bulimia nervosa is associated with numerous severe health complications resulting from the cycle of bingeing and compensatory behaviors. These adverse physical effects include kidney failure, heart failure, and significant tooth decay. Additionally, individuals with this disorder frequently suffer from mental health issues, such as anxiety and depression, and face an elevated risk for substance abuse.

Health Consequences of Bulimia Nervosa

Anorexia nervosa leads to numerous severe health problems, making it one of the most lethal mental disorders. Significant negative outcomes include bone loss, heart failure, kidney failure, amenorrhea (the cessation of menstruation), and reduced function of the gonads. In extreme cases, these complications can result in death.

Health Consequences of Anorexia Nervosa

Analyze the following clinical case. Based on the patient's symptoms, explain the likely underlying behaviors and the physiological mechanisms connecting those behaviors to each of the observed health issues.

Clinical Symptom Analysis

While Avoidant/Restrictive Food Intake Disorder (ARFID) is similar to anorexia nervosa in involving significant food restriction, individuals with ARFID do not intend to lose weight, nor are they anxious about their body size or shape. Thus, any dramatic weight loss is unintentional. Other consequences of ARFID include:
- Malnutrition
- Loss of appetite
- Stomach cramping
- Lanugo
- Heart failure resulting from malnutrition
- Loss of menstrual cycle
- Abnormal laboratory results
