Low back pain can be caused by a number of factors from injuries to the effects of aging.
Low Back Sprain and Strain - A sprain of the low back can occur when a sudden, forceful movement injures a ligament which has become stiff or weakthrough poor conditioning or overuse.
These injuries, are the most common causes of low back pain. Frequently, a combination of other factors may increase the likelihood of injury or disease:
- poor conditioning
- improper use
- obesity
- smoking
The natural effects of normal aging on the body, in general, and low back, in particular, are osteoporosis or decreased bone density; decrease in strength and elasticity of muscles; and decrease in elasticity and strength of ligaments
Although you cannot totally halt the progress of these effects, they can be slowed by regular exercise, knowing the proper way to lift and move objects, proper nutrition, and avoidance of smoking.
Age - "Wear and tear" and inherited factors will cause degenerative changes in the discs, called degenerative disc disease, and arthritic changes in the spinal joints. These changes occur to some degree in everyone. When severe, they can cause low back stiffness and pain. Arthritic bone spurs and inflamed joints can cause nerve irritation and leg pain.
Osteoporosis and Fractures - All bones lose bone strength over time and the lumbar vertebrae, particularly in postmenopausal women, can be fractured or compressed from a fall or even from the stress of lifting or everyday activities.
Protruding Disc - The disc is composed of a soft center or nucleus, which, in children and young adults, is jelly-like. The nucleus is surrounded by a tougher outer portion called the anulus. With normal aging, the nucleus begins to resemble the anulus. During middle-age, fissures or cracks may occur in the disc. These may be the source of back pain. If the crack extends out of the disc, material from the disc may push out or rupture. This often is referred to as a herniated or slipped disc. If the protruded disc presses a nerve, it may cause pain in the leg. |
