Has your primary care doctor or spine physician suggested you lose weight to help reduce the severity of your lower back pain? Maybe you have back pain, but haven’t considered extra body weight to be a potential cause. Even an added 10 pounds can contribute to increased back pain.
BMI and What It Means
BMI is a number based on your weight and height. In general, the higher the number, the more body fat a person has. There are four categories of BMI:
For example, a person who is 5’10” tall and weighs 174 pounds has a BMI of 25, while a person who is 5’10” and weighs 251 pounds has a BMI of 36.
Obesity and risk for low back pain by the numbers
The study did not address why obesity increases the risk of low back pain. However, extra body weight can contribute to how the spine functions—its mechanical well-being.
Small changes in the level of activity can substantially reduce the risk for low back pain. People with extreme obesity (BMI 36+) who increase their time in moderate activities 17 minutes per day may reduce their risk for low back pain by 32%. Moderate activities may include briskly walking, performing water aerobics, riding a bike, ballroom dancing, and gardening.
