A properly working immune system identifies foreign substances in the body that might cause illness, such as bacteria and viruses. The immune system then creates antibodies which attack the foreign substances, neutralizing them and keeping the body safe. In people with autoimmune disorders, something goes wrong with this process. For reasons that are not fully understand, the immune system creates antibodies to attack the patient's own tissues.

Symptoms of an autoimmune disorder depend on which tissue is being attacked by the immune system, but common symptoms of autoimmune disease include fever, fatigue, and a general feeling of just not being well. Autoimmune disorders are more common in women than in men, and they may run in families. Autoimmune disorders can affect various parts of the body such as blood vessels, connective tissue, endocrine glands, joints, muscles, red blood cells, skin, and many others.

It is common to have more than one autoimmune disorder at a time. Most are chronic, or life-long illnesses, although they may come and go in flares. Treatment for autoimmune disorders depends on which part of the body is being attacked. For example:

• A type 1 diabetic whose pancreas has been damaged will need insulin.
• A person with Hashimoto's whose thyroid has been damaged will need replacement thyroid hormones.
• Someone with Sjogren's syndrome will need eye drops and mouth rinses to replace tears and saliva.

Many autoimmune disorders of all kinds are treated with immune-suppressing medications, such as corticosteroids (e.g. prednisone) to reduce the effect of the immune system.

We don't yet know what causes depression, but it's thought that it is a combination of genetic, biological, environmental, and social influences. Because of this, the most effective treatments for depression combine medication with psychotherapy. Therapy, especially cognitive-behavioral therapy, can be extremely helpful in resolving the negative thoughts and feelings that come with depression. It gives patients new tools that they can use themselves to cope when their depression is making them feel down.

Some of the common medications used to treat depression include antidepressants such as SSRI's (Prozac, Paxil, Zoloft) or atypical antidepressants (Cymbalta, Wellbutrin). It's important to remember that these medications have different effects on everybody, and no one medication works right for everyone. Patients may have to try a couple before finding the one that works just right for them. If the first medication they try doesn't work, they should talk to their doctor about trying something else. In extreme cases where medication is not enough, electro-convulsive therapy and hospitalization may be the answer to keeping a severely depressed person safe.

Depression is a difficult illness to deal with, but it is more common than believed and there are many people who can help. With the right treatment, individuals with depression can get back to fully enjoying life again.

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.
