About Constipation & Gas
Chronic constipation and excess gas point to a digestive system that is moving slower or less smoothly than it should. The pace of your gut, known as motility, is largely set by the nervous system, which signals the intestines when to contract and move things along. Much of that nerve supply travels from the lower-thoracic and lumbar spine. When those signals are dysregulated, the gut can slow down, stool can become hard and infrequent, and gas can build up and cause discomfort.
The pattern is often shaped by low fiber or fluid intake, a sedentary routine, stress, certain medications, and an imbalanced gut. The gut-brain connection plays a real role here too, since the same nervous system that manages stress also manages digestion. Because the lower-thoracic and lumbar nerves help drive gut motility, tension or restriction through the mid and lower back can be part of a picture that diet changes alone do not fully resolve.
Our approach looks at the nerve supply behind your digestion, not just the diet around it. We map the nervous system first with a thorough neurological evaluation to understand how the regulating side of your nervous system and the related areas of your spine are functioning. Then we build a personalized care plan with gentle, hands-on care meant to support healthy regulation, working alongside your medical care and any guidance from your physician or dietitian.

When To Seek Medical Care
Talk to your doctor first if…
Certain digestive changes call for prompt medical evaluation. See a doctor right away for blood in your stool or black, tarry stools, unexplained weight loss, severe or persistent abdominal pain, or constipation paired with vomiting and an inability to pass gas, which can signal a blockage. A sudden, marked change in your bowel habits that lasts more than a couple of weeks should also be checked by your physician, since ongoing constipation can sometimes reflect a condition that needs medical management.
