Introduction and objective:
Endometriosis (EM) is a chronic inflammatory disease for which pharmacological treatment does not always give the desired results. "The importance of diet in the course of the disease is increasingly highlighted. The aim of the study was to evaluate the nutritional behaviour and physical activity of women with EM and the influence of the abovementioned factors on the specific symptoms of the disease".

Material and methods:
A cross-sectional study was conducted using an online questionnaire-based survey. The questionnaire was posted on social media groups related to endometriosis and diet, obtaining 230 responses. Correlations between variables were examined using Spearman›s rank correlation coefficient. The significance of differences between the independent groups was tested using the Mann-Whitney U test.

According to the survey, 64.8% of women participating in the study adhered to a diet because of EM. The most frequent changes in nutritional habits were reduction in the consumption of sugar and sweets, and resignation from fast foods. There were significant differences between the group of women adhering to a diet,and the group of women not adhering to a diet in the consumption of products such as red meat, fish, milk and dairy products, legumes, white bread, gluten-free bread, seeds and nuts, gluten-free groats, cereals, fruits, vegetables, sweetened beverages, and fruit juices. Following dietary changes, 83.9% of the women reported an improvement in at least one of the endometriosis symptoms.

The study proves that women with EM seek relief through dietary modifications, with the majority experiencing improvements in symptoms and well-being after making the changes. Further research is required to establish what kind of a diet and what type of products are the most efficient in alleviating the symptoms of endometriosis
