There are a few ways to answer your question but I will give the short version. Yes a chiropractor and the chiropractic adjustment can help with relieving constipation. The bony spinal structures called vertebrae house the spinal cord and the spinal nerves. These nerves not only produce pain but they also control visceral function, organ function. So if there is abnormal or restricted motion in the spine causing inflammation to spinal nerves and these spinal nerves control stomach, bowel (intestinal( function then by relieving and or removing the irritation to these nerves, which is called a vertebral subluxation, then the nerves can function normally and the body returns to normal function, normal homeostasis. There is simple to understand chart called the Meric system which shows where on the vertebral column of the human body will affect the organs of our body. In addition there is also the Vagus nerve of the human body which originates in the neck, cervical spine, and aid in the control of just about all our organs including the intestines. So, you see, yes Chiropractic and the chiropractic adjustment can certainly help to eliminate constipation.
