Anxiety means feeling excessive worry, nervousness, or unease, often with physical symptoms.
Doctors use this term because anxiety can affect both the mind and the body. It can show up as thoughts, emotions, or physical sensations. Anxiety is a condition and a symptom pattern, not just “being stressed.”
Anxiety can be short-term or ongoing.
Doctors most often use anxiety because of common situations such as:
Stressful life events or ongoing stress
Health worries or fear of symptoms
Poor sleep or exhaustion
Caffeine or stimulant use
Underlying medical or hormonal changes
Anxiety often has more than one contributing factor.
Anxiety can cause a wide range of symptoms, including:
Chest tightness or shortness of breath
Dizziness or lightheadedness
Nausea or stomach discomfort
Rapid heartbeat
Muscle tension or body aches
Trouble sleeping
Symptoms can feel very real and physical.
Anxiety activates the body’s stress response, which affects breathing, heart rate, muscles, and digestion.
Anxiety can change breathing patterns, making breaths faster or shallower, which creates the sensation of breathlessness.
Muscle tension and stress-related breathing changes can cause chest discomfort that feels alarming but is not heart-related.
Stress hormones can affect blood flow, breathing, and blood sugar, leading to dizziness or shakiness.
Doctors may evaluate anxiety using:
Symptom discussion and history
Review of stress, sleep, and daily habits
Physical exam
Blood tests to rule out medical causes if needed
Doctors often rule out physical causes first, then assess anxiety patterns.
Anxiety is often first addressed by a primary care doctor.
Mental health professional – for therapy or counseling
Psychiatrist – for medication management if needed
Referral depends on symptom severity and impact on daily life.
For many people, next steps may include:
Stress and anxiety management strategies
Improving sleep and daily routines
Therapy or counseling
Medication if appropriate
Follow-up if symptoms continue
Anxiety is treatable, and many people improve with support.
