Can anxiety cause real physical symptoms?

Anxiety is both a mental and a physical experience. The state of alert triggered by the autonomic nervous system produces real, measurable physical symptoms, including:

Cardiovascular: heart palpitations, a racing heart rate, a feeling of pressure in the chest Respiratory: shortness of breath, a sense of not getting enough air, hyperventilation Muscular: neck and shoulder tension, tension headaches, jaw clenching Gastrointestinal: nausea, diarrhea, irritable bowel syndrome, abdominal pain Neurological: dizziness, tingling, lightheadedness, tremors

These symptoms are completely real — they are not imagined. The body is responding to a threat signal sent by the nervous system, even when no real threat is present.

The diagnostic challenge is that these symptoms lead many people with anxiety to see multiple specialists (cardiologist, gastroenterologist, neurologist) before receiving the correct diagnosis. Not finding a physical cause can actually increase anxiety, fueling worry about a serious illness that has "gone undetected."

The most effective path: rule out physical causes when clinically indicated, then address anxiety as the primary cause with appropriate treatment.
