Anxiety disorder: symptoms, treatment, and when to see a doctor
Last updated September 6, 2026.
**Generalized anxiety disorder is worry that runs most days about many different things, for at least six months, and is hard to switch off.** The worry comes with body symptoms like muscle tension, restlessness, and poor sleep, and it takes up enough of your day that work, school, or relationships suffer. Treatment works well and usually starts with cognitive behavioral therapy, an SSRI or SNRI medicine, or both together. What changes urgency is any thought of harming yourself, a first episode of chest pain or fainting, or symptoms that started right after a new medicine or after stopping alcohol or a sedative.
What are the symptoms of Generalized anxiety disorder?
- Worry you cannot control, on more days than not, about several areas of life
- Feeling restless, keyed up, or on edge
- Muscle tension, jaw clenching, tension headaches, or aching shoulders
- Trouble falling asleep or staying asleep because your mind keeps running
- Trouble concentrating, or your mind going blank
- Getting tired easily, and feeling irritable with people close to you
- Stomach upset, nausea, or frequent urge to use the bathroom when stressed
Worry that is tied to one specific trigger, that started in the last few weeks after a clear life event, or that comes only in sudden ten minute surges of pounding heart and breathlessness points more toward an adjustment reaction, a specific phobia, or panic disorder than toward generalized anxiety disorder.
How does a doctor diagnose Generalized anxiety disorder?
There is no blood test for generalized anxiety disorder, so the diagnosis rests on the pattern of your story plus a check for look alike medical causes. A clinician asks how long the worry has been going on, whether it jumps from topic to topic rather than sitting on one problem, how many days per week it happens, and which body symptoms travel with it. Screening tools like the GAD-7 questionnaire put a number on severity and give a baseline to compare against later. You will also be asked about caffeine, alcohol, cannabis, stimulant medicines, decongestants, and recently stopped sedatives, since all of these can produce the same picture. Depending on your age and symptoms, a doctor may check a thyroid panel, a basic metabolic panel, and a blood count, and may look at heart rate and blood pressure or order an ECG if palpitations are prominent. Depression, trauma history, and alcohol use are screened at the same visit because they often travel with anxiety and change the treatment plan.
How is Generalized anxiety disorder treated?
- Cognitive behavioral therapy: CBT is first-line and works as well as medicine for many people, usually over 12 to 16 weekly sessions with practice between visits. It targets worry habits directly, using techniques like scheduled worry time, testing feared predictions, and reducing reassurance seeking and avoidance.
- SSRI medicines: Sertraline, escitalopram, and paroxetine are standard first-line drug choices, started at a low dose and raised slowly. Expect some jitteriness or nausea in the first week or two, real benefit at four to six weeks, and a plan to stay on the medicine for at least a year after you feel well before tapering.
- SNRI and other second-line medicines: Venlafaxine extended release and duloxetine are the usual next step if an SSRI does not help or is not tolerated. Buspirone is an alternative with no sedation or dependence risk, and pregabalin is used in some countries including the UK. Hydroxyzine may be used short term for breakthrough symptoms.
- Careful use of benzodiazepines: Drugs like lorazepam and clonazepam calm symptoms within an hour but are not a long-term answer, since tolerance, rebound anxiety, and dependence build within weeks. If they are used at all, it is at the lowest dose for a few days to a few weeks while a therapy or SSRI plan takes effect.
- Daily habits that change symptom load: Cutting caffeine to one drink a day or less, limiting alcohol, regular aerobic exercise most days, and a fixed sleep and wake time reduce baseline arousal measurably. These are worth doing alongside therapy or medicine, not instead of them.
When is Generalized anxiety disorder an emergency?
Call 911 or go to the emergency room if you have thoughts of killing yourself, a plan, or you have hurt yourself; you can also call or text 988 for the Suicide and Crisis Lifeline any time. Go to the ER for chest pressure lasting more than a few minutes, chest pain spreading to the arm or jaw, fainting or near fainting, a heart rate that stays above 120 at rest, one sided weakness or slurred speech, or shortness of breath that continues once you are calm, since these need a heart, lung, and stroke workup rather than an anxiety label. Go to the ER if you stopped drinking heavily or stopped a benzodiazepine and now have shaking, sweating, vomiting, confusion, or a seizure, which is withdrawal and can be dangerous. Also treat as an emergency any combination of fever, agitation, muscle twitching, and racing heart after a dose increase or a new medicine added to an antidepressant, which can signal serotonin syndrome. Urgent care or a same-day primary care visit is the right level for anxiety that has stopped you from eating, sleeping, or going to work for several days, for a first panic attack in someone over 40, or for new anxiety with weight loss, tremor, and heat intolerance that may be an overactive thyroid.

Common questions
How is generalized anxiety disorder different from normal stress?
Normal stress has a subject and an end point: a deadline, a diagnosis, a move. Generalized anxiety disorder jumps between topics, keeps going after the situation resolves, and shows up on most days for six months or more. The second marker is cost. If worry is making you miss work, avoid calls, sleep badly, or snap at people you love, it has crossed from stress into a treatable condition. Clinicians look for that combination of duration, spread across topics, and functional impact rather than the intensity of any single worried day.
How long do anxiety medicines take to work, and how long will I be on them?
An SSRI or SNRI usually gives partial relief by two to four weeks and full benefit by six to twelve weeks, so judging it after five days is too early. The first one to two weeks can feel worse, with jitteriness, nausea, or disturbed sleep, which is why doses start low and go up slowly. Once you feel well, standard advice is to stay on the medicine for at least twelve months before considering a taper, because stopping early raises the chance of relapse. When you do stop, the dose is reduced gradually over weeks to avoid discontinuation symptoms like dizziness and electric shock sensations. Never stop an antidepressant abruptly on your own.
Can I treat generalized anxiety disorder without medication?
Yes. Cognitive behavioral therapy alone is a proven first-line treatment and matches medicine for many people with mild to moderate symptoms, with the advantage that the skills keep working after therapy ends. Applied relaxation, structured exposure to avoided situations, and mindfulness based programs also have evidence behind them. Cutting caffeine, limiting alcohol, exercising most days, and keeping fixed sleep and wake times lower baseline arousal enough to be noticeable. Medication tends to be added when symptoms are severe, when therapy is not available or has not worked, or when depression is present alongside the anxiety.
Why does my anxiety cause physical symptoms like chest tightness and stomach problems?
Sustained worry keeps the sympathetic nervous system switched on, which raises muscle tone, speeds up breathing, and changes gut motility. That produces real chest wall tightness, tension headaches, a lump in the throat sensation, nausea, and urgent bowel movements. These symptoms are genuine, not imagined, and they usually track with your worry level through the day. That said, a first episode of chest pain, chest pain on exertion, fainting, or symptoms in someone over 40 with heart risk factors deserves a medical workup before being attributed to anxiety.
Should I avoid caffeine completely?
You do not have to quit entirely, but the dose matters. Caffeine raises heart rate and adrenaline and can reproduce anxiety symptoms directly, and people with anxiety disorders are often more sensitive to it. A practical target is one caffeinated drink before noon, with attention to hidden sources like energy drinks, pre workout powders, and some headache tablets. Cut down over about a week rather than stopping suddenly, since abrupt withdrawal causes headache and irritability that feel like worse anxiety. Alcohol is worth reviewing at the same time, because it calms symptoms at night and rebounds them the next morning.
What should I do during a bad anxiety episode right now?
Slow your breathing out longer than in, for example four counts in and six counts out, for two to three minutes, which reduces the physical arousal driving the feeling. Put your feet on the floor and name what you can see and hear around you to break the loop of catastrophic thinking. Avoid checking, googling symptoms, or seeking reassurance, since those lower anxiety for minutes and strengthen it over weeks. If it passes within an hour and you can function afterward, book a routine appointment. If you have thoughts of hurting yourself, call or text 988, and if you have chest pain, fainting, or trouble breathing that does not settle, get emergency care.
