Overweight people

Excess weight is one of the factors that increase the risk of back pain. However, there are several ways of reducing this risk.

In most cases excess weight is due to the increased fat formation typical of obesity. However, some sportsmen and sportswomen who intensively practice certain sports such as weight-lifting and body-building may weigh more than normal owing to increased muscle mass.

Excess weight has been shown to be a risk factor for the back when it is considerable and due to obesity, but not when it is due to increased muscle mass.

What increases the risk of back pain in persons who are overweight due to obesity?

There are several factors:

  • The excess weight itself. Excess weight in itself increases the burden on the vertebral disc, which accelerates wear and increases the risk of deformation or breakage. It also forces the back muscles to work harder to move the body or maintain a posture, with heightened risk of spasm and pain. Well-developed and trained muscles protect the vertebral disc and increase the load capacity and endurance of the spinal column. Therefore, if excess weight is due to augmented muscle mass, there is no increased risk of back trouble.
  • Other associated factors. Persons whose excess weight is due to obesity are normally exposed to other risk factors for back pain, such as:
  • Sedentariness, which in itself increases the risk of back pain.
  • Weakness of the back and abdominal muscles has been shown to be one of the factors that increase the risk of new or persisting pain. Muscular weakness renders the musculature liable to overloading and spasm in response to apparently slight strains. Moreover, the less muscle mass there is, the more exposed is the vertebral disc and other structures in the spinal column, the less is this able to withstand loads, and the greater is the risk of some spinal disorder.
  • Lack of physical activity. In normal conditions, the different muscle groups involved in the functioning of the back, such as the abdominals and the paravertebral musculature, coordinate with one another to maintain a posture or maintain balance in movement. This coordination depends on nerve reflexes, which need to be repeated in order to work properly. Physical inactivity causes loss of training and deterioration of these reflexes, so that the muscles contract in the wrong way or at the wrong time and become susceptible to spasm.
  • Poor general health. In the medium and long term, excess weight increases the risk of various disorders, like metabolic and cardiovascular disease. Poor general health is one of the factors that increase the risk of back problems.
  • Can back pain have prejudicial consequences for a person who is overweight?

    Yes. Essentially, the risk of it becoming chronic.

    As long as excess weight lasts, the back is continually exposed to a heightened risk of renewed pain. The repetition and increasing duration of bouts of pain are factors that increase the risk of the pain persisting for longer or becoming chronic.

    Moreover, especially if obese people are not much given to physical activity, pain may prompt them, wrongly, to repose, to further limit their physical activity, to adopt an evasive and pessimistic attitude to the pain and put off starting exercises which have proven to be effective in the treatment and prevention of back problems.

    All these factors increase the risk of pain and functional or work disability appearing, persisting and becoming chronic.

    The good news is that there are effective ways of guarding against these risks.

    How to prevent and treat back pain in overweight persons.

    Obviously, the ideal thing for the back and general health is to reduce weight in the appropriate way, by limiting and reforming eating habits and doing regular exercise. If this applies to you, see your doctor and take up whatever program you find most suitable and comfortable.

    But even while the excess weight persists, there are effective ways of preventing back problems, such as:

  • Keep as physically active as possible. Besides helping you to lose weight and being good for your general health, keeping as physically active as possible is an effective way of preventing back pain. In may be as simple as getting used to making day-to-day journeys on foot rather than sitting in the car, metro or bus, or taking the stairs up a few flights rather than always taking the elevator. If possible, it is even better to do some aerobic sports like running or swimming. With 20 or 30 minutes on alternate days, you will begin to note a considerable difference. If you are going to start doing a sport regularly, you should first consult a doctor to assess your general condition and you should observe the rules of postural hygiene in sports, with which you can do almost any of them with less risk to your back.
  • Know and observe the rules of postural hygiene. These teach you how to adopt everyday postures and movements that involve the least burden for your spinal column and muscles. This is especially important for overweight people, in whom the load itself is greater than normal.
  • Maintain and develop the back muscles. Strong back and abdominal muscles reduce the risk of back problems. This is especially important in people who are overweight, because the strain on these muscles is greater than normal. In a person with good muscle strength and endurance, a few extra kilos may not matter to the back. If done correctly and regularly, some aerobic exercises like swimming may be enough to keep your back muscles and your general physical condition in good trim. Specific exercise programs for the back are only effective for these muscles and not for general fitness, but they require less time and can be alternated with aerobic exercises when you have time. There is a section of this site that shows effective exercises for this.
  • If you experience pain, you must apply the right treatment. This site contains a section that lists all the existing treatments for back pain, and there is another that indicates the common patterns of treatments that have proven effective.

    If the pain that a sedentary person suffers is shown to be an organic disorder of the spinal column, such as a herniated disc, the treatments indicated for that disorder should be followed. These are indicated in the section dealing specifically with fissures, protrusions and herniated discs.

    But before treating a herniated disc, we need to show that this is really what is causing the pain. Thirty per cent of healthy people who experience no discomfort have protrusions or herniated discs which cause them no trouble, and signs of vertebral disc wear can be observed in almost everyone aged over 30.

    Therefore, any X-ray, scan or magnetic resonance of a sedentary person will normally show wear of the vertebral disc, and there will probably be deformation or breakage. But the image alone is not enough; if there are no symptoms or these do not correspond exactly to what the image shows, then it is not necessary to apply a specific treatment.

    Thirty per cent of the healthy population exhibit protrusions or herniated discs that produce no symptoms. One day, such people may suffer a common back pain due to improper functioning of the muscles or to a muscular spasm. In any case it would be wrong to attribute such symptoms to the herniated disc, and it would be counter-productive to operate.

    Therefore, complementary examinations like X-rays or magnetic resonance should only be performed when there are concrete grounds to support this. If there are no such grounds, it is pointless to conduct these examinations given that their results will not modify the treatment. It could even be counter-productive, since the observation of an unrelated herniated disc may confuse the diagnosis and lead to incorrect, unnecessarily aggressive or even counter-productive treatment.

    It is therefore also essential to study the characteristics of the symptoms and determine whether or not these correlate exactly with the organic disorders shown by the image. This means that the clinical history and physical examination are even more important sources of information than magnetic resonance. It would be wrong to diagnose a herniated disc without first interviewing and examining the patient. Only if the patient's symptoms and the result of the examination correspond exactly to the image does it make sense to diagnose this as the cause of the pain and establish a treatment on that basis.
