Overview
Anxiety is a feeling of fear, tension, or unease that can happen in response to stress, danger, or uncertainty. In some people, anxiety becomes frequent, intense, or difficult to manage and starts to interfere with daily life. Anxiety-related conditions can include generalized anxiety, panic symptoms, social anxiety, and specific phobias.
Key Symptoms
Symptoms can include excessive worry, feeling restless or on edge, irritability, trouble concentrating, and sleep problems. Physical symptoms may include a racing heart, sweating, shaking, shortness of breath, chest discomfort, nausea, dizziness, or muscle tension. Some people have sudden episodes of intense fear called panic attacks.
Causes and Risk Factors
Anxiety does not have one single cause. It can be linked to stressful life events, trauma, family history, personality, ongoing health problems, certain medicines or substances, and use of alcohol or drugs. Caffeine, poor sleep, and chronic stress can also make symptoms worse in some people.
Who Is Affected
Anxiety can affect children, teenagers, adults, and older adults. It occurs in people of all cultures, genders, and backgrounds. Symptoms may look different depending on age, life situation, and the presence of other health conditions.
Prevention
Not all anxiety can be prevented, but some habits may reduce stress and support mental health. Regular sleep, physical activity, social connection, stress-management skills, and limiting alcohol or stimulant use may help some people. Early support after trauma or during periods of high stress may also be useful.
Diagnosis and Tests
A healthcare professional or mental health professional usually diagnoses anxiety by asking about symptoms, how long they have lasted, and how much they affect daily life. They may also ask about sleep, substance use, medications, trauma, and other mental health concerns. Sometimes medical evaluation is needed to look for physical conditions that can cause similar symptoms, such as thyroid problems or heart-related symptoms.
Treatment Categories
Treatment often includes psychotherapy, such as forms of talk therapy that help people understand and manage anxious thoughts and behaviors. Some people may also be offered medicine by a qualified clinician. Treatment plans vary from person to person, and follow-up is important because symptoms can change over time.
Living With It
Living with anxiety can involve learning triggers, noticing early warning signs, and building coping skills over time. Support from family, friends, peer groups, school staff, or employers may help reduce isolation. Recovery may not be a straight line, and symptoms can improve with ongoing care and practical support.
Diet and Lifestyle
Healthy routines can support overall well-being, even though they do not replace professional care when anxiety is severe. Regular meals, enough sleep, movement, and limiting caffeine, alcohol, and recreational drugs may help some people manage symptoms. Relaxation practices such as slow breathing, mindfulness, or grounding exercises may also be useful for some people.
When to Seek Medical Care
Seek medical care if anxiety is frequent, hard to control, causes panic symptoms, affects sleep, or interferes with school, work, relationships, or daily tasks. Medical care is also important if symptoms start after a new medicine, substance use, a major life event, or alongside depression or physical symptoms such as chest pain or fainting. If you are unsure whether symptoms are from anxiety or another health problem, get evaluated.
When It May Be an Emergency
Get emergency help right away if someone is thinking about suicide, has made a suicide plan, may harm themselves or others, or cannot stay safe. Emergency care is also needed for severe chest pain, trouble breathing, fainting, confusion, seizures, or symptoms after an overdose or substance use, because these may have causes other than anxiety. If immediate danger is present, contact local emergency services now.
