Gas (flatus) is made in the stomach and intestines as your body breaks down food into energy. All people pass gas, some people more than others. It is normal to pass gas from 6 to 20 times per day. Common causes of gas include: 1  Swallowed air. If swallowed air is not burped up, it passes through the digestive tract and is released through the anus as flatus. Excessive air swallowing may cause hiccups.  Foods and beverages. The amount of gas that different foods cause varies from person to person.
Spinal Stenosis. What is Spinal Stenosis? Spinal stenosis is defined as the narrowing of the spinal canal, most often in the cervical (neck) area and in the lower back (lumbar) region. This condition places pressure on the spinal cord, with patients most often experiencing problems when inflammation of the nerves occur as the pressure is increased.
If the narrowing is substantial, it causes compression of the spinal cord or spinal nerves, which causes the painful symptoms of lumbar spinal stenosis, including low back pain, buttock pain, and leg pain and numbness that is made worse with walking and relieved by resting.Medically Reviewed by a Doctor on 5/7/2015. Lumbar spinal stenosis is a condition whereby either the spinal canal (central stenosis) or one or more of the vertebral foramina (foraminal stenosis) becomes narrowed. 2  Lumbar spinal stenosis is typically caused by degenerative arthritis.
