Coronavirus Disease 2019 is not 'just in your head' — it produces measurable physical symptoms through well-understood neurobiological pathways.
Why Coronavirus Disease 2019 Causes Physical Symptoms
The brain and body are not separate systems. Coronavirus Disease 2019 activates:
- The HPA axis: releasing cortisol that affects virtually every body system
- The autonomic nervous system: creating the physical experience of threat
- Inflammatory pathways: affecting immune function and tissue health
- The enteric nervous system (gut-brain axis): digestive symptoms common in coronavirus disease 2019
Common Physical Symptoms of Coronavirus Disease 2019
- Muscle tension, headaches, and chronic pain patterns
- Digestive symptoms: IBS, nausea, appetite changes
- Sleep disruption and fatigue
- Cardiovascular: heart palpitations, elevated blood pressure over time
- Immune effects: increased susceptibility to illness
When Physical Symptoms Are Primarily Coronavirus Disease 2019
Physical symptoms from coronavirus disease 2019 are real, not imaginary. But they're best treated by addressing coronavirus disease 2019 directly, alongside symptomatic relief when needed.
