Obesity and Back Pain

A person can be overweight and not be obese. It is important to understand the difference between the two terms. Obesity means having a higher than normal percentage of body fat. Usually, anyone who is 20% over the normal weight for his or her age, sex, build and height is considered obese.
The structure of the human skeleton is not well adapted to carry an extra load of body fat for a long period of time. Consequently, long-term obesity left untreated, is a major contributing factor to back and joint pain and muscle strain. The most vulnerable region of the spine is the lower back or lumbar spine that has to carry the weight of the body.
An extraordinary large complex of muscles in the lower back is the iliopsoas. Its lower segments are attached to the pelvis, hips and thighbones; while its upper extremities go to every vertebra in the lumbar area of the lower spine, and to the lower thoracic vertebrae in the middle of the spine. The iliopsoas causes the natural curve in the spine, controls the general posture and is involved with the entire working of the back and hips.
Prolonged lack of exercise and obesity can cause the iliopsoas to weaken, lose tone and even atrophy. An unnatural strain and pressure is placed on the bones to which it is attached, especially the spine. The vertebral discs have to carry the extra burden of weight placed upon them. This can lead to a worsening of the symptoms associated with osteoarthritis, rheumatoid arthritis, vertebral disc degeneration, disc herniation, sciatica and osteoporosis whereby the bones can fracture.
Poorly conditioned iliopsoas muscles, weakened abdominal muscles and excess fat around the stomach combine to mechanically increase the curvature in the lower part of the spine. The abdominal wall becomes overstretched and the whole pelvis can tilt forward. This puts pressure on the lower back and its muscles, causing back pain and poor posture. The spine becomes less flexible and more susceptible to injury. Exercises to firm up abdominal muscles are an important part of bad back therapy.
Emotional stress or anxiety, which is often relieved by overeating, in particular, the carbohydrate fix, can lead to obesity, poor self-image and back pain. Remember that excess carbohydrate is stored as fat. A balanced diet and regular exercise are most important in maintaining a healthy weight, which in turn may help to reduce the severity of existing back problems and prevent the occurrence of new ones.
Proper nutrition hastens the healing processes and strengthens the affected tissues. Exercise improves circulation of blood which carries nutrients to the area.
Drink at least eight glasses of pure filtered water every day. This may help in reducing the desire to overeat by creating a feeling of fullness. Also the hydration of the muscles and joints of the spine may reduce the severity of pain.
Always consult your health care professional to determine the type of exercise program, dietary changes and nutritional supplements that will best suit you.
