The underlying hypothesis of the study is that patients with chronic pain that go through a series of nutrition education (individual and group) specifically tailored to fit their needs (based on our preliminary findings), they increase the consumption of foods that have antiinflammatory properties, which will result in lower levels of inflammatory cytokines in the body (high sensitivity C-reactive protein (hs-CRP ), interleukin (IL) -2, IL-4 and IL-6), and consequently reduce the intensity of pain. Also, weight loss in obese patients is expected, and it will have an contributing effect of the intervention. Patient's quality of life and indicators of their psychophysical condition (eg, depression level) are also expected to improve.~Chronic pain patients who either attend Daily clinic (Control Arm) or the 4-week multidisciplinary programme at the Department of Anesthesiology, Resuscitation and Intensive Care (Intervention Arm) will be recruited. They will be followed for total of 8 weeks (4 week intervention + 4 week follow-up).
The primary objective of the study is to determine the effectiveness of nutrition education (individual and group) on the intensity of pain in patients suffering from chronic pain. The secondary goal is to determine whether there is a change in the status of the patient's nutrition, their quality of life, quality of life, and other indicators of the psychophysical condition of the patient.
