Anorexia may also cause bluish discoloration of the hands, brittle and falling out hair, yellowish skin, and lanugo (fine, downy hair). These physical symptoms are frequently accompanied by altered behaviors and emotions. Those with anorexia may feel compelled to hide their weight and actions from others. For example, someone with anorexia may wear oversized or baggy clothing to conceal weight loss or may deny hunger or lie about the amount of food that he or she consumes. Some people with anorexia may withdraw from social activities and may experience irritability and depression.

People of all ages, genders, and races may be diagnosed with anorexia; however, the condition affects more women than men. There is no single known cause for anorexia, but biological, psychological, and environmental factors may play a role. Athletes who participate in certain sports that emphasize body shape and size (such as ballet, figure skating, and wrestling) may be more likely to develop anorexia.

Anorexia has two subtypes that are referred to as the restrictive type and binge-purge type.

Restrictive type is the more frequently represented form of anorexia, involving the extreme restriction of food. Binge-purge type anorexia is food restriction accompanied by episodes of binging (eating large quantities of food) and purging (vomiting). Binge-purge type anorexia differs from bulimia as people with this type of anorexia severely limit calories and purge most of what they eat and are generally underweight, while those with bulimia are in a normal weight range. Left untreated, both types of anorexia have severe and life-threatening effects on health. Anorexia can lead to heart failure and even death.

Many people do not consciously develop anorexia, and have difficulty seeking treatment. For this reason, early detection and treatment helps with long-term recovery outcomes. Treatment for anorexia can vary from therapy visits to inpatient treatment, depending on the severity of a person's anorexia. Severe anorexia is typically treated in inpatient rehabilitation facilities, where patients increase their food consumption and gain weight under medical supervision. Eating disorder specialists provide therapy sessions and oversee a physical and mental treatment plan. Outpatient programs help patients return to a healthy weight through frequent talk therapy or cognitive behavioral therapy (CBT) sessions, specialized nutrition plans, and eating disorder support groups. Anorexia treatment aims to not only restore physical health and correct negative behaviors, but to also promote psychological well-being and self-confidence.

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.

IBS, or irritable bowel syndrome, happens when the muscles surrounding the colon contract too easily or frequently. The result is abdominal pain, cramps, diarrhea or constipation, gas and bloating. IBS attacks can often be brought on by specific triggers, so a key part of treatment is learning which foods trigger IBS attacks and avoiding them. Treatment also includes exercise, avoiding stress, and medications if needed.

Constipation, or large, hard, or infrequent stools, happens to everyone at some point. It can be caused by a disruption in routine or food, or by eating a diet without many fresh fruits and vegetables. Although it is uncomfortable, constipation is common and usually not serious, but it can sometimes become chronic. Adding fiber to the diet, exercising, and taking medications may help.

GERD, or gastroesophageal reflux disease, is a severe form of chronic heartburn where stomach acid spills back up into the esophagus. Left untreated, the acid may even eat away at the esophagus and cause serious damage. Treatment includes changing the diet to avoid trigger foods, losing weight if needed, medications, or even surgery.

Hemorrhoids are blood vessels around the rectum that become irritated, swollen or torn while straining during a bowel movement. They are most often caused by constipation, but can also be caused by pregnancy, diarrhea, or simply a genetic predisposition towards hemorrhoids. Treatment involves first treating any constipation issues, then keeping the area clean and soothed until it has healed. If these measures are ineffective, surgery is sometimes used.

Peptic ulcers are sores or spots of inflammation in the lining of the stomach or close to the stomach in the small intestine. Usually this area is coated with a protective lining that shields the tissue from the strong stomach acid, but a break in the lining can let acid in, causing the sores. It used to be thought that stress caused ulcers, but now it is known that is not the case. Most often, they are caused by an infection by H. pylori bacteria, but ulcers can also be caused by alcohol abuse or overuse of aspirin, ibuprofen, naproxen, or other NSAIDS. The symptoms of an ulcer are pain, hunger, nausea, and fatigue.

Gastrointestinal problems, perhaps more than any other area, are markedly affected by lifestyle. Many disorders can be prevented or treated at least in part by eating a healthy diet high in fiber, exercising regularly, drinking enough water, and limiting alcohol intake. Still, the frequency of digestive disorders means that even the healthiest person can be affected by them. Anyone who notices blood in their stool, experiences abdominal pain, unexplained weight loss, or any significant change in bowel movements should see a doctor.
