The purpose of this study is to evaluate of body mass index and eating behaviour changes in female patients with fibromyalgia under medical treatment.

The female patients with fibromyalgia under medical treatment say that body mass index and eating behaviour changes,for this reason, this relationship will be investigated in this study.

Demographic data (sex, age, education level, occupation) of patients with fibromyalgia diagnosis will be questioned and height lengths will be measured. The group of medications (serotonin and norepinephrine reuptake inhibitor or GABAergic drugs) that begins with the diagnosis of the disease fibromyalgia will be recorded.

All patients will be assessed when diagnosed, followed by 2nd week and then 4nd week.

In each follow-up, the patients' weights will be measured again (the body mass index will be calculated from the measured value).

In each follow-up, the effect of fibromyalgia on the daily life of the patients will be questioned with Fibromyalgia Impact Questionnaire (FIQ). The FIQ was developed from information gathered from patient reports, functional status instruments, and clinical observations. This instrument measures physical functioning, work status (missed days of work and job difficulty), depression, anxiety, morning tiredness, pain, stiffness, fatigue, and well-being over the past week.

In each follow-up, patients' eating behaviour will be questioned with Three Factor Eating Questionnaire. The 18-item Three-Factor Eating Questionnaire is a scale that measures three domains of eating behavior: cognitive restraint , uncontrolled eating and emotional eating.

In each follow-up, the right calf circumference of the patients will be measured in centimeters with a tape measure .
