Generalized Anxiety Disorder is persistent and excessive worry that's hard to control, Mark Pollack, MD, board-certified psychiatrist and chief medical officer for Myriad Mental Health, maker of the GeneSight test, tells Eat This, Not That! "The topic of the worry can be any number of things—money, health, relationships, work, etc."

Regardless of the topic of worrying, people who suffer from anxiety often experience similar symptoms, Pollack explains. This can include feeling nervous, irritable, having a sense of impending doom, or experiencing difficulty concentrating or sleeping.

Like depression, there are many possible causes of anxiety.

Like depression, diabetes and heart disease, anxiety is a medical disorder, Dr. Pollack reminds us. "You may be able to reduce your risk of getting the disorder by going to therapy with a mental health professional, getting regular exercise, eating a balanced diet, etc. However, just like other disorders, it may not be entirely preventable, due to no fault of the person suffering."

First and foremost, both you and family members/loved one should recognize that anxiety is not due to a lack of will—it's an illness like depression, heart disease, diabetes, etc.—Dr. Pollack points out. "You should think of your loved one or yourself as suffering with a medical condition. Offer yourself and others the same kindness and support."

He suggests reaching out to a trusted healthcare provider like a general practitioner. "They can do an anxiety screening to assess your mental health," he explains. "For treatment, they may explore a variety of treatment options including medication, talk therapy or other things."

If it is your friend or loved one suffering from anxiety, he stresses the importance of listening to them over talking. "You should consider asking the patient about how you can be helpful," he suggests.
