Can Chiropractic Help With Asthma? What the Research (and 23 Years of Experience) Says
Chiropractic for asthma sounds surprising — until you understand the neurological connection between the thoracic spine and the lungs. Dr. Dan Foss explains the mechanism and what he's seen clinically in San Antonio.

When patients bring up asthma in a chiropractic office, they sometimes look apologetic — like they expect to be told they're in the wrong place. Asthma is a pulmonary condition. Chiropractors work on spines. What's the connection?
It's a fair question. The answer is more compelling than most people expect.
The Thoracic Spine and Respiratory Control
Your thoracic spine — the 12 vertebrae of your mid-back — is not merely a structural component. It's the origin of the nerve roots that control the muscles of respiration, including the intercostal muscles between the ribs that expand and contract the chest wall, and the diaphragm, the primary breathing muscle.
The phrenic nerve, which controls the diaphragm, originates primarily from C3, C4, and C5 — cervical levels that are directly influenced by upper thoracic and cervical function. The intercostal nerves branch from thoracic levels T1 through T12.
When the thoracic vertebrae are misaligned or restricted — which is extremely common in people who sit for long periods, have poor posture, or have experienced any kind of spinal trauma — the nerve supply to the respiratory muscles is compromised. The ribcage becomes restricted, limiting its ability to fully expand. The diaphragm doesn't receive optimal neurological input.
This doesn't cause asthma in the allergic, immunological sense. But it can significantly affect breathing mechanics and the severity of respiratory symptoms in people who already have compromised airways.
What the Research Shows
The research on chiropractic and asthma is mixed but interesting. Several studies have shown that chiropractic adjustments to the thoracic spine improve lung function measurements and reduce the frequency and severity of asthma attacks in some patients — particularly children.
A study published in the Journal of Manipulative and Physiological Therapeutics found that children with asthma who received chiropractic care alongside their standard medical treatment showed significant improvements in disability scores and decreased severity of asthma attacks. The proposed mechanism was improved thoracic mobility and enhanced nervous system regulation of bronchomotor tone.
It's important to be honest here: chiropractic is not a cure for asthma. It doesn't address the allergic or immunological components. It doesn't replace inhalers or other medical management. But for patients with asthma that has a significant mechanical component — restricted thoracic mobility, poor respiratory mechanics, compromised neurological input to the breathing musculature — chiropractic can meaningfully improve their ability to breathe and reduce the frequency of symptomatic episodes.
What I See in Practice
Over 23 years in San Antonio, I've seen a consistent pattern: patients who come in primarily for back or neck complaints, who also have asthma or a history of frequent respiratory infections, often report that their respiratory symptoms improve as we address their thoracic dysfunction.
It's not a coincidence. When the thoracic spine moves properly, the ribcage expands more fully. The diaphragm functions more efficiently. The nervous system regulates bronchomotor tone more effectively. The body breathes better.
I've had patients — adults and children — who were able to reduce their rescue inhaler use as their thoracic dysfunction resolved. Not because I was "treating" their asthma, but because restoring proper thoracic mechanics improved the overall respiratory environment.
What Chiropractic for Asthma Looks Like
At Pura Vida Chiropractic, I evaluate asthma patients for:
Thoracic restriction and misalignment — particularly at the upper thoracic levels (T1-T5), which have direct neurological connections to bronchomotor tone and respiratory muscle function. Restricted thoracic mobility prevents full ribcage expansion and limits breathing depth.
Cervical involvement — particularly upper cervical dysfunction affecting the phrenic nerve pathway. C3-C5 restrictions are common in asthma patients and can directly affect diaphragm function.
Costochondral and rib joint restriction — the joints where the ribs articulate with the thoracic vertebrae and with the sternum frequently become restricted in people with chronic respiratory conditions. Restoring motion to these joints improves chest wall compliance.
Postural assessment — forward head posture, thoracic kyphosis, and rounded shoulders all mechanically compromise breathing capacity by reducing the anterior-posterior diameter of the thoracic cavity.
Treatment addresses all of these components using SOT chiropractic adjustments, specific rib mobilization techniques, and soft tissue work targeting the accessory breathing muscles.
Realistic Expectations
If you have asthma and are considering adding chiropractic to your care plan, here's what to expect: you should not stop your medications. You should not expect immediate resolution of symptoms. What you can expect is a systematic evaluation of the thoracic and cervical spine, precise correction of any mechanical dysfunction present, and a gradual improvement in breathing mechanics over the course of care.
Some patients see significant improvement. Some see modest improvement. A small number don't see respiratory benefits, though the structural correction typically helps with other symptoms. This variability is real, and I'll be transparent about it.
What I won't do is tell you chiropractic can cure your asthma. What I will tell you is that if your thoracic spine is compromised — and in most adult asthma patients, it is — there's a good chance that addressing it will help you breathe better.
