Weight Loss for Back Pain Relief

Every extra pound of weight adds strain to the muscles and ligaments of the back. To compensate for extra weight, the spine tends to become tilted and stressed unevenly. Excess stomach weight typically pulls the pelvis forward (increasing lumbar lordosis), leading to aggravated lower back pain.

Following proper nutrition can help to decrease the risk for back pain, joint pain and muscle strain.

This article reviews how extra weight leads to back problems, and guidelines for how to use exercise, diet, and weight loss to reduce back pain.

Obesity Leads to Back Pain

Obesity is associated with an increased risk of back pain. Excess weight also tends to prolong the recovery period after episodes of back pain.1

Persons who are obese and/or have a high percentage of body fat are:

  • 33% more likely to experience low back pain2
  • 35% more likely to experience severe, intense pain2
  • Up to 43% more likely to develop chronic low back pain3,4
  • For men, up to 50% more likely to experience disability and functional limitations5
  • For women, about 100% more likely to experience disability and functional limitations6

Back pain has a strong association with body mass index (BMI),6 a mathematical formula (BMI=kg/m2) that considers one’s weight in kilograms related to height in meters. On the index, a score between 18.5 and 24.9 is considered normal, between 25 and 29.9 is considered overweight, and above 30 is considered obese.

In addition to BMI, it is also important to assess where the excess fat is stored on the body, such as around the waist or in the legs.

Notable Symptoms of Back Pain Connected to Excess Weight

Individuals who are obese or severely overweight and have back pain tend to exhibit one or more of the following symptoms:

  • Fatigue during short periods of exercise
  • Difficulty breathing or shortness of breath
  • Pain in the leg or knee that is more severe than pain in the back
  • Increase in pain with back extension7 (bending backward)

Back pain is more likely to become a chronic, ongoing condition if leg and back pain increase with extension.3 These symptoms make exercise challenging, but not impossible.

Types of Back Pain Related to Obesity

Higher body weight increases the likelihood of developing several serious health conditions, such as type 2 diabetes, high blood pressure, and heart disease. Obesity is also related to conditions that specifically affect the spine and lower back, namely:

  • Herniated discs. Obese or overweight patients are considered more likely to experience a herniated disc, a common cause of leg pain or sciatica due to a lumbar radiculopathy. The disc is more likely to herniate as it is forced to compensate for the pressure of extra weight on the back.8
  • Osteoarthritis. Extra body weight strains joints in the spine and leads to an increased risk of developing spinal osteoarthritis. A BMI greater than 25 increases the risk of developing osteoarthritis.9

On occasion, degenerative spinal conditions may need to be treated with surgery. Obesity has been associated with a greater risk of complication or infection in individuals who require surgery.10 Surgery typically remains worthwhile when medically indicated.8,11 Weight loss before undergoing back surgery may help improve the postsurgical healing process.

Ways to Reduce Weight for Back Pain Relief

Methods of weight loss have been studied for their ability to relieve pain. Active programs have fared far better than passive advice, information, or lifestyle coaching. It is important for individuals who have back pain and are overweight or obese to take action and change daily habits for long-lasting results.

The most recommended ways (tier 1 and tier 2 weight management services12) to lose weight include:

  • A healthy diet
  • Frequent, moderate to high-intensity exercise
  • Counseling with a professional to achieve behavioral changes13

Avoiding physical activity due to fatigue and shortness of breath weakens the back further, and indirectly leads to more intense back pain. Fear of pain with movement (kinesiophobia) is a mediating factor between intense pain and limited ability to perform daily tasks.14 For some, overcoming the fear of physical activity is an important step to losing weight and relieving pain.

Alternative ways (tier 3 weight management services) to lose weight include:

  • A low-energy liquid diet, which is best followed under medical supervision10
  • Prescription medications, such as orlistat (Xenical), which may lead to serious liver injury10
  • Leptin therapy, which are hormone injections that help prevent the body from regaining lost weight10

Tier 4 weight management involves bariatric surgery, which reduces the severity of back pain and disability scores and increases the quality of life.15

Bariatric surgery is usually considered for individuals whose body mass index is above 35 to 40, if safer and healthier methods of weight loss have not proven effective over 6 to 12 months. Bariatric surgery poses numerous short-term and long-term risks, such as bleeding of the digestive tract, bowel obstruction, nutritional deficiencies, hernia, a venous blood clot that moves into the lungs (venous thromboembolism), reoperation, and rarely, death.16

Bariatric surgery can only do so much to help an individual lose weight and to help curb food cravings. It is important that bariatric surgery is combined with a nutritional program and regular exercise. The patient has to be highly motivated to not only lose weight but also to keep the weight off.
