What kind of doctor treats Generalized Anxiety Disorder?
A psychiatrist, a doctor who treats mental health conditions, often treats generalized anxiety disorder. A psychologist, an expert in talk therapy, may help too. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is generalized anxiety disorder?
Many people worry about things such as health, money, school, work, or family. People with generalized anxiety disorder (GAD) feel extremely worried or nervous more often or more strongly about these and other things. The worry is out of proportion with the situation.
GAD usually involves a constant feeling of anxiety or dread. It interferes with how you live your life. These feelings can last for months or even years. GAD develops gradually and usually starts in early adulthood, although it can occur at any age.
Symptoms
The main symptom is frequent worry or tension for at least 6 months, even when there is little or no clear cause. People with GAD may:
- Worry excessively about everyday things.
- Have trouble controlling their worries or feelings of nervousness.
- Often feel irritable or on edge.
- Feel restless or have trouble relaxing.
- Have a hard time concentrating.
- Have trouble falling asleep or staying asleep, or feel tired.
- Have pain such as headaches, muscle aches, stomachaches, or tension.
- Sweat a lot, feel lightheaded, or feel out of breath.
Children and teens with GAD may worry about the same things as adults. Their worries often center on school, activities, friendships, and the future.
Symptoms may go up and down over time. They are often worse during times of stress.
Causes and who gets it
GAD may run in families. The exact cause is unknown. Research suggests GAD comes from a mix of genetics, brain chemistry, biology, and environment. A traumatic event or a stressful setting may raise a person's risk.
Women are more likely than men to experience GAD. An estimated 2.7% of U.S. adults had GAD in the past year. About 5.7% of U.S. adults experience GAD at some time in their lives.
Some people with GAD also have other conditions. These include depression, other anxiety disorders, and post-traumatic stress disorder.
How doctors diagnose it
There is no test that can make a diagnosis of GAD. The diagnosis is based on your answers to questions about the symptoms.
A person must find it hard to control worry on most days for at least 6 months. They must also have at least three of these symptoms: feeling restless or on edge, fatigue, trouble concentrating, irritability, muscle tension, or problems with sleep.
A physical exam or lab tests may check for other conditions with similar symptoms. You can start with a primary care doctor, psychiatrist, psychologist, or social worker.
Treatment
GAD treatment typically involves psychotherapy, medication, or both.
Psychotherapy, also called talk therapy, can work well. Cognitive behavioral therapy (CBT) is commonly used to treat GAD. CBT helps people notice harmful thoughts and question them.
Different types of medicine can be effective. These include antidepressants such as SSRIs and SNRIs. They also include anti-anxiety medicines such as benzodiazepines and buspirone.
SSRIs and SNRIs may take several weeks to start working. Side effects can include headaches, nausea, or trouble sleeping. You must take these medicines every day. Do not stop them without talking with your provider.
Benzodiazepines can be used to manage severe forms of GAD. Some people build up a tolerance to them, and some people become dependent on them. So a provider may prescribe them only for brief periods of time. Buspirone is another anti-anxiety medicine that can help. It is not a sedative and has less potential to be addictive than benzodiazepines.
Less caffeine and enough sleep can reduce anxiety symptoms when paired with standard care. Healthy habits alone cannot replace treatment.
Most people get better with medicine or talk therapy.
When to see a doctor
Seek professional help if anxiety causes problems in everyday life. This includes problems at school, at work, or with friends and family.
If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away. In life-threatening situations, call 911.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can listen to your concerns, do a first evaluation, follow up with you over time, and help you reach a mental health specialist.
Common questions
Is generalized anxiety disorder the same as normal stress?
No, GAD is not the same as occasionally worrying about things or having anxiety due to stressful life events. Occasional stress and anxiety are normal. They should not control your life.
Can generalized anxiety disorder be treated?
Yes, GAD can be treated. With the right treatment and support, people with GAD can manage their anxiety and improve their quality of life.
Do I need medicine for generalized anxiety disorder?
Not always. Talk therapy or medicine alone can be helpful, and sometimes a combination works best.
How long does generalized anxiety disorder last?
GAD feelings can last for months or even years. In some cases, GAD is long-term and is difficult to treat.
