Of both genders, it is the fairer sex that suffers back pain the most. According to medical studies, almost half of women in the age group of 45-64 and a third in the age group ranging from 16 years to 24 years, suffer either from upper or lower back pain. Often the lower back pain sufferers are in greater proportion then those suffering from upper back pain. Generally, there are many causes for low back pain in women, but the biggest single source is pregnancy. It is said that 2 in every 3 women will suffer lower back pain in either their eighth or ninth month of pregnancy. And it is easier to understand why. As a baby grows inside the uterus, it expands outwards. In order to counter that outward or forward push, women naturally tend to pull themselves back. This forced push in the opposite direction not only causes immense strain on their backbones, but also stretches their abdominal muscles, hence, lower back pain ensues. But then there are other many causes of low back pain women. Some of these are: After pregnancy, probably, weight is the second biggest reason for lower back pain in women. Excess weight causes pressure on the spine due to which women especially those who choose to stay at home suffer from low back pain. Menstruation cycle is yet another main cause for back pain in women. >Women who are stay-at-home moms, especially with younger children, suffer back pain. With constant baby care, they tend to develop acute lower back pain over time. There are certain professions in which women workers suffer back pains in greater numbers than those working in other professions. These professions are health, retailing, banking, insurance and the hospitality industry.Of all the professional women, (female) nurses suffer the most. Every year thousands of them drop out of work due to constant back pain. Then in second position are those who work in clerical positions. With constant sitting, sometimes up to three to four hours at a stretch cause immense low back pain. Housework is another major cause for low back pain in women: With constant cleaning, washing clothes and dishes, it is only natural that over a period of time, they develop a constant annoying aching back. And last but not least, there is this fashion thing. Doctors constant remind their female patients against wearing high heels as they cause immense strain on their pelvic areas, which in turn affects their backs. Tight clothes, especially tight pants also cause strain on their lower backs.
