Anorexia nervosa, frequently referred to as anorexia, is a disorder where people severely restrict the types and quantity of food they eat. Those with anorexia have an extreme fear of eating and gaining weight and may repeatedly weigh themselves or engage in harmful behaviors such as excessive exercise or starvation. Those with anorexia often find themselves preoccupied with food, but unable to consume a healthy amount of it. This results in symptoms such as abnormally low BMI, vitamin deficiency, fatigue, fainting, and amenorrhea (lack of menstruation in women). Anorexia may cause bluish discoloration of the hands, brittle and falling out hair, yellowish skin, and lanugo (fine, downy hair). Left untreated, anorexia can lead to organ failure, brain damage, and even death.

Bulimia nervosa, typically called bulimia, is a disorder where people binge (eat large quantities of food) and purge the food that they just consumed by vomiting, laxative abuse, fasting, or excessive exercise. This behavior is usually motivated by a feeling of powerlessness over eating and a fear of weight gain or desire for weight loss. Bulimia can occur in underweight, normal weight, and overweight people. Symptoms of bulimia include acid reflux, intestinal distress, dehydration from purging, amenorrhea, and dental erosion from vomiting. Some people with bulimia have swollen parotid glands (salivary glands near the cheeks) and red scars and marks on the backs of their knuckles. Electrolyte imbalance from bulimia can be particularly severe and may lead to heart attack or stroke.

Binge eating disorder (BED) is the most common eating disorder. People with BED feel that they are unable to control the amount of food they eat and may continue to binge after reaching a point of fullness. BED binges (consuming large amounts of food) are often accompanied by feelings of sadness, guilt, and shame. Symptoms of BED include obesity, acid reflux, weight gain, and dissatisfaction with one's body. People with BED tend to experience cycles of negative emotions and binges. Binges or BED episodes can be provoked by stress, boredom, restrictive dieting, depression, and other triggers.

Other common eating disorders include:

• Pica, eating things that are not food, such as paper, ice, or soil
• Avoidant/Restrictive Food Intake Disorder (ARFID), disinterest in eating and avoidance of food
• Other Specified Feeding or Eating Disorder (OSFED), abnormal eating that does not fall under any disorder

Many people with eating disorders do not consciously develop them, and have difficulty seeking treatment. For this reason, it's important to detect and treat eating disorders as early as possible. Treatment for eating disorders can vary from therapy visits to inpatient treatment, depending on the disorder and its severity. Treatment aims to not only restore physical health and correct negative behaviors, but to also promote psychological well-being and self-confidence.

Hashimoto's is the leading cause of hypothyroidism, which is when the thyroid does not produce enough hormones to stimulate adequate metabolism. The condition is diagnosed by blood tests that measure TSH (thyroid stimulating hormone) and detect Hashimoto's antibodies. Symptoms of hypothyroidism include sluggish metabolism, inflammation, fatigue, weight gain, brittle hair, dry skin, and sensitivity to cold. To supplement impaired thyroid function, patients with Hashimoto's are typically prescribed synthetic thyroid hormone pills. Such patients may need to consume synthetic thyroids for the rest of their lives. Other treatments may include dietary changes, such as the avoidance of certain foods and medication to reduce inflammation. Frequent blood tests can inform patients if their TSH levels are within a normal range.

Grave's disease is most frequently the cause of hyperthyroidism, which is when the thyroid produces too many hormones, overstimulating one's metabolism. The condition is also diagnosed by blood tests that measure TSH and detect Grave's antibodies. Elevated heart rate, high blood pressure, sweating, bulging eyes, and weight loss are common symptoms of hyperthyroidism. Treatments for hyperthyroidism include oral radioactive iodine, which slowly shrinks the thyroid, slowing the production of excess thyroid hormone. Other anti-thyroid medications such as methimazole (Tapazole) also reduce the production of thyroid hormones. Blood pressure medications known as beta blockers can ease the increased heart rate caused by hyperthyroidism. If treatments are unsuccessful, patients may be prescribed a thyroidectomy, or surgery to remove part or all of the thyroid. Some patients with hyperthyroidism may require ophthalmological (eye medicine) treatments such as eye drops, prednisone, and surgery to reduce eye swelling and bulging.

Untreated thyroid disorders frequently lead to goiters or thyroid nodules. A thyroid goiter is a large lump that can be felt near the base of the neck and is made of swollen thyroid tissue or nodules (excess cell growth). Nodules and goiters are diagnosed by CT scan or ultrasound. Obstructive goiters can cause pain, coughing, and abnormal breathing. The most common cause of goiters is hyperthyroidism (overactive thyroid). However, Hashimoto's is also known to cause goiters or nodules. Goiters develop from continued damage from antibodies to the thyroid over time. At times, a goiter can result from a cancerous thyroid tumor. Most goiters and nodules are themselves benign.

The exact causes of thyroid cancer are unknown. People who develop thyroid cancer may or may not have another thyroid problem such as Hashimoto's or Grave's disease. Symptoms of thyroid cancer include a nodule that can be felt on the neck, hoarseness, difficulty swallowing, swelling in the neck, and neck and throat pain. CT and MRI scans are used to diagnose thyroid cancer. There are four types of thyroid cancer which vary in intensity. Thyroidectomy (thyroid removal surgery) is usually prescribed to treat thyroid cancer.

Thyroid problems are often long-term conditions that require some form of treatment. With regular monitoring and medication, many people with thyroid problems are able to lead active and fulfilling lives.
