Anxiety Symptoms: What to Look For and When to Get Help
Anxiety symptoms can be physical, emotional and behavioral. Learn the most common signs of anxiety, what causes them, how they differ from normal stress, and when to get help.
Common anxiety symptoms include constant worry, restlessness, feeling on edge, a racing heart, chest tightness, shortness of breath, muscle tension, stomach upset, trouble sleeping, irritability and difficulty concentrating. Anxiety becomes a disorder when these symptoms are intense, last for weeks or months, and interfere with daily life.
Key takeaways
- Anxiety disorders are the most common mental health conditions in the U.S., affecting about 19% of adults each year.
- Symptoms are physical (heart, breathing, stomach, muscles), emotional (worry, dread) and behavioral (avoidance).
- Normal anxiety passes with the situation; an anxiety disorder lingers and gets in the way of life.
- Physical symptoms are real and caused by the body’s stress response, not “just in your head.”
- Anxiety is highly treatable with therapy, medication and lifestyle changes.
Your heart pounds before a meeting. You lie awake replaying conversations. Your stomach is in knots for no clear reason, and your mind will not stop asking “what if?” Everyone feels anxious sometimes; anxiety is a normal, even helpful, response to danger. But when it shows up most days, out of proportion to what is happening, and starts shaping your choices, it may be an anxiety disorder.
According to the National Institute of Mental Health, an estimated 19.1% of U.S. adults have an anxiety disorder in any given year, and about 31% will experience one in their lifetime. This guide walks through the full range of anxiety symptoms, what causes them, who is most at risk, how anxiety differs from stress and from other conditions, and exactly when to get help.
What is anxiety?
Anxiety is your body’s built-in alarm system. When your brain senses a threat, it triggers the “fight, flight or freeze” response: stress hormones such as adrenaline and cortisol surge, your heart speeds up, breathing quickens and muscles tense, preparing you to act. That system is life-saving in real danger.
In an anxiety disorder, the alarm goes off too easily, too strongly or too often, even when there is no real danger. The main types of anxiety disorders include:
- Generalized anxiety disorder (GAD): excessive, hard-to-control worry about many things for six months or more
- Panic disorder: repeated, unexpected panic attacks and fear of having more
- Social anxiety disorder: intense fear of being judged or embarrassed in social situations
- Specific phobias: intense fear of a particular object or situation
- Health anxiety: persistent worry about having a serious illness
- Separation anxiety: excessive fear of being apart from loved ones, which can occur in adults too
Related conditions such as OCD and PTSD also involve high anxiety.
Physical symptoms of anxiety
Many people first notice anxiety in their body, and some go to the emergency room or their doctor convinced something is medically wrong. Physical anxiety symptoms include:
- 01Heart
Racing or pounding heart
Palpitations or a sense your heart is skipping beats.
- 02Breathing
Shortness of breath
Feeling you cannot get a full breath, or breathing fast and shallow.
- 03Chest
Chest tightness
Pressure or tightness across the chest.
- 04Stomach
Stomach upset
Nausea, butterflies, cramps, diarrhea or IBS flares.
- 05Muscles
Tension and aches
Tight shoulders, jaw clenching, headaches, back pain.
- 06Body
Sweating, trembling, shaking
Clammy hands, shaky voice or trembling.
- 07Body
Dizziness or lightheadedness
Feeling faint or unsteady.
- 08Energy
Fatigue
Being “on” all the time is exhausting.
- 09Sleep
Insomnia
Trouble falling asleep, waking up with a jolt, restless sleep.
- 10Body
Tingling or numbness
Pins and needles in hands, feet or face, often from overbreathing.
Important: because anxiety symptoms can mimic heart, lung or thyroid problems, see a doctor to rule out medical causes, especially for new chest pain.
Emotional and mental symptoms
- Constant or excessive worry that is hard to control
- A sense of dread or that something bad is about to happen
- Feeling on edge, keyed up or restless
- Irritability and a short fuse
- Racing thoughts and “what if” thinking
- Trouble concentrating or your mind going blank
- Overthinking decisions and seeking reassurance
- Feeling detached or unreal during intense anxiety
Behavioral signs of anxiety
Anxiety also changes what you do, often in ways that keep it going:
- Avoidance: skipping events, calls, driving or anything that triggers anxiety
- Procrastination: putting off tasks that feel overwhelming
- Checking and reassurance-seeking: rereading emails, checking symptoms online, asking others if things are okay
- Over-preparing and perfectionism
- Using alcohol, cannabis or food to calm down
- Withdrawing from friends and activities
Avoidance brings short-term relief but teaches the brain that the situation really was dangerous, so anxiety grows over time. Effective treatment gently reverses this pattern.
Normal anxiety vs an anxiety disorder
| Normal anxiety | Anxiety disorder | |
|---|---|---|
| Trigger | A clear, real stressor | Often no clear trigger, or out of proportion |
| Duration | Passes when the situation ends | Lasts weeks to months |
| Intensity | Manageable | Overwhelming, hard to control |
| Impact | Does not stop you doing things | Leads to avoidance and affects work, sleep and relationships |
| Physical symptoms | Brief | Frequent or constant |
Anxiety vs depression
Anxiety is focused on fear and the future; depression is marked by low mood, emptiness and loss of interest. They often occur together, and about half of people with depression also have an anxiety disorder. Learn more about depression.
What causes anxiety?
Anxiety disorders usually come from a combination of factors:
- Genetics: anxiety runs in families
- Brain chemistry: differences in how the brain regulates fear and stress
- Life experiences: trauma, childhood adversity, loss, ongoing stress
- Personality: perfectionism, sensitivity and a strong need for control
- Medical conditions: thyroid disorders, heart rhythm problems, asthma, chronic pain
- Substances: caffeine, nicotine, alcohol withdrawal, cannabis, some medications and supplements
- Other conditions: ADHD, depression and insomnia raise anxiety risk
Who is most at risk?
Anxiety can affect anyone, but it is more common in women, who are about twice as likely as men to have an anxiety disorder. Risk is also higher for people with a family history, those who experienced trauma or chronic stress, people with chronic illness, new parents, students and people facing major life transitions. Symptoms often begin in adolescence or early adulthood but can appear at any age.
When to get help for anxiety symptoms
Reach out to a professional if:
- Worry or physical symptoms happen most days for two weeks or more
- You are avoiding places, people or tasks because of anxiety
- Anxiety is affecting your sleep, work, school or relationships
- You are having panic attacks
- You are using alcohol or other substances to cope
- You also feel down, hopeless or numb
Seek emergency care for chest pain you are unsure about, fainting, or thoughts of harming yourself.
How anxiety is treated
Anxiety disorders respond very well to treatment. Most people improve significantly with one or a combination of:
Cognitive behavioral therapy (CBT)
The most researched therapy for anxiety. CBT teaches you to notice and challenge anxious thoughts and gradually face feared situations through exposure.
Medication
Antidepressants such as SSRIs and SNRIs are first-line medications for many anxiety disorders. Other options exist for specific situations. A psychiatric provider can explain benefits and side effects through medication management.
Lifestyle changes
Regular exercise, consistent sleep, cutting back on caffeine and alcohol, and limiting doom-scrolling all lower baseline anxiety.
Skills you can practice daily
Slow breathing (inhale for 4, exhale for 6), grounding with your five senses, progressive muscle relaxation, mindfulness and scheduled “worry time.”
Treating what comes with it
Addressing insomnia, depression, ADHD or medical causes often makes anxiety much easier to manage.

Frequently asked questions
What are the most common symptoms of anxiety?
The most common symptoms are excessive worry, restlessness, feeling on edge, a racing heart, shortness of breath, muscle tension, stomach upset, fatigue, irritability, trouble concentrating and trouble sleeping.
What are the physical symptoms of anxiety?
Physical symptoms include a pounding heart, chest tightness, shortness of breath, sweating, trembling, dizziness, nausea, stomach cramps, headaches, muscle tension, tingling and fatigue. They are caused by the body’s stress response.
Can anxiety cause chest pain?
Yes, anxiety can cause chest tightness or pain, often from muscle tension and rapid breathing. Because chest pain can also signal a heart problem, new, severe or unexplained chest pain should always be checked by a doctor or emergency services.
How do I know if my anxiety is normal or a disorder?
Normal anxiety is linked to a real situation, is manageable and fades afterward. An anxiety disorder involves anxiety that is intense, out of proportion, lasts weeks or months and interferes with work, sleep or relationships.
Can anxiety make you feel sick?
Yes. Anxiety commonly causes nausea, stomach pain, diarrhea, headaches and a general unwell feeling. The gut is closely connected to the brain’s stress system.
What does an anxiety attack feel like?
An anxiety attack usually builds gradually in response to stress and involves intense worry, restlessness, a fast heartbeat and tension. A panic attack comes on suddenly and peaks within minutes with intense fear, pounding heart, shortness of breath and sometimes a feeling of losing control.
Can anxiety cause shortness of breath?
Yes. Anxiety often causes fast, shallow breathing or a feeling of not getting enough air. Slow, extended exhalations can help. Seek medical care if breathing difficulty is severe, new or accompanied by other symptoms.
Why is my anxiety worse at night?
At night there are fewer distractions, so worries come to the surface. Fatigue, caffeine late in the day, screens and an irregular sleep schedule can also make nighttime anxiety worse.
Can anxiety go away on its own?
Mild, situational anxiety often passes. Anxiety disorders tend to persist or come and go without treatment, and avoidance can make them worse. Treatment shortens the course and lowers the chance of relapse.
What triggers anxiety?
Common triggers include stress at work or home, health worries, money problems, conflict, caffeine, alcohol, lack of sleep, social situations, and reminders of past trauma. Sometimes there is no clear trigger.
Is anxiety a mental illness?
Anxiety disorders are recognized mental health conditions, and they are among the most common and most treatable. Feeling anxious occasionally is a normal human experience, not an illness.
Can anxiety affect your memory and concentration?
Yes. Anxiety takes up mental bandwidth, making it hard to focus, remember things or make decisions. These symptoms usually improve as anxiety is treated.
What is the best treatment for anxiety?
Cognitive behavioral therapy and certain medications, especially SSRIs and SNRIs, are the most proven treatments. Many people do best with a combination, plus lifestyle changes such as exercise and better sleep.
When should I see a doctor about anxiety?
See a provider if anxiety lasts more than two weeks, causes you to avoid things, affects your sleep, work or relationships, involves panic attacks, or if you are using substances to cope.
Can I get treated for anxiety online?
Yes. Telepsychiatry is an effective way to be evaluated and treated for anxiety. GraceBridge Psychiatry offers online anxiety care for adults in Texas, Arizona and Washington.
