Physiological causes
As mentioned earlier in the first chapter, women tend to suffer more from back pain
than men. Physiological reasons for this disparity are:
- Periods: Backache is common during periods but is usually cyclical and
disappears once the periods are underway or end. However, there is a condition
called endometriosis, discussed in a later chapter, where cells from the lining of
the womb implant abnormally in the pelvis and back. This can give rise to
excruciating pain many days before the period starts and persist long after the
period ends. - Pregnancy increases women's vulnerability to back problems. During pregnancy,
hormonal and other body changes result in:
a. Loosening and weakening of ligaments
b. Abnormal lordotic posture with the tummy jutting out in front and the
buttocks thrust backwards
c. Progressively increasing weight due to increase in fat and the growing
baby
All of these changes contribute to back pain. It is estimated that between 40%
and 60% of pregnant women get back pain.
