Anorexia is an eating disorder. It occurs when a person’s obsession with diet and exercise leads to extreme weight loss. The disorder is considered if a person refuses to maintain a body weight at or above 85% of their ideal body weight. It can be fatal.
The cause of anorexia is not known. It appears that genetics and environment play a role.
(Alcohol Dependence; Alcohol Use Disorder)
Alcohol abuse is problem drinking that negatively impacts your life. For example, you may experience one or more of these issues due to alcohol abuse:
Alcoholism or alcohol dependence is a problem pattern of drinking where you can have the same issues as alcohol abuse. Alcoholism also includes continued drinking even when there are clear problems related to alcohol that affect your physical and mental health. Relationships with family members, friends, and coworkers also suffer. Due to the more intense pattern of drinking, you may not be able to stop drinking once you start, have withdrawal symptoms if you stop drinking, and develop a tolerance (meaning you need to keep drinking more to feel the same effect).
Agoraphobia is an irrational fear of being trapped in places or situations where escape could be difficult or impossible. People with agoraphobia often will not leave the house. It often occurs in association with panic disorder. In this case, the affected people may fear that help will not be available in certain places in case a panic attack occurs.
Changes or genetic problems in the nervous system (brain and nerves) may contribute to agoraphobia.
