What kind of doctor treats Anxiety?
A psychiatrist, a doctor who treats mental health problems, often leads care for anxiety. A psychologist or licensed therapist gives talk therapy. A primary care doctor can also diagnose anxiety and start treatment. 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 anxiety?
Anxiety is a feeling of fear, dread, and uneasiness. It can be a normal reaction to stress. It can even help you cope by giving you energy or focus. An anxiety disorder is different. The fear does not go away. It can get worse over time. It can hurt your work, school, and relationships.
There are several types of anxiety disorders. Generalized anxiety disorder (GAD) causes excess worry about ordinary things such as health, money, work, and family. The worry comes almost every day for at least 6 months. Panic disorder causes panic attacks. These are sudden times of intense fear when there is no danger. Phobias are strong fears of things that pose little or no real danger, such as flying, crowds, or social events.
Symptoms
Different types of anxiety disorders can have different symptoms, but they share a few common ones:
- Anxious thoughts that are hard to control and keep coming back.
- Body symptoms, such as a fast heartbeat, dizziness, short breaths, tight muscles, sweating, or aches with no clear cause.
- Changes in behavior, such as avoiding everyday activities you used to do.
- Trouble focusing, being easily annoyed, feeling tired, and sleep problems.
Causes and who gets it
The exact cause of anxiety disorders is not known. Genes, brain chemistry, stress, and your setting in life may all play a role. Anxiety often runs in families. Traumatic events in childhood or adulthood raise the risk. So can some health problems, such as a thyroid problem or arrhythmia, an abnormal heart rhythm.
GAD and phobias are more common in women. Social anxiety affects men and women equally. Being shy in new situations also raises the risk. Caffeine, other drugs, and some medicines can make symptoms worse.
How doctors diagnose it
There is no single test for anxiety disorders. The doctor will ask about your symptoms and health history. You may get a physical exam and lab tests. These check that another problem, such as a thyroid problem, is not the cause. If not, you will get a psychological evaluation. That is a detailed set of questions about your mental health. Your doctor may do it or send you to a mental health expert.
Treatment
The main treatments are psychotherapy (talk therapy), medicines, or both. One common talk therapy is cognitive behavioral therapy (CBT). It teaches you new ways to think and act. It may include exposure therapy, which helps you face your fears instead of avoiding them. Another type, acceptance and commitment therapy, may help some people.
Medicines can also help. These include some antidepressants, medicines that treat depression. SSRIs are most often the first choice. An SSRI is a type of antidepressant. An SNRI is another option. You may need to try more than one medicine to find the right one. Sedatives such as benzodiazepines should only be taken under a provider's direction, in limited amounts, and usually not every day. Most people get better with medicine or talk therapy.
When to see a doctor
Contact your doctor if you often worry or feel anxious, especially if it gets in the way of your daily life. Depression and substance abuse can come with an anxiety disorder, so getting help matters. If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away. Call 911 for chest pain that lasts two minutes or more, trouble breathing, or fainting, even if you think it is anxiety. Call 911 in any life-threatening situation.
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. Either can do an initial evaluation and rule out physical causes. They can also refer you to a psychiatrist or therapist and follow up with you over time.
Common questions
Can anxiety disorders be cured?
There is no single cure, but most people get better with medicine or talk therapy. In some cases GAD lasts a long time and is harder to treat. Treatment aims to help you feel better and live well day to day.
What is the difference between fear and anxiety?
Anxiety is a feeling of fear, dread, and uneasiness. Anxiety can be a normal reaction to stress, such as before a test or a big choice. In an anxiety disorder, the fear does not go away and can get worse over time.
Do I need medicine to treat anxiety?
Not always. Talk therapy alone, medicine alone, or both can help. Some medicines work better for certain anxiety disorders. Work closely with your provider to find what is best for you.
Can lifestyle changes help anxiety?
Yes. Cutting back on caffeine helps. So does avoiding street drugs and heavy drinking. Exercise, rest, healthy food, and a regular schedule can all help. Support groups may also add to therapy and medicine.
