Background: Eating disorders are a problem that is becoming more and more common among younger and younger age groups. Many studies examine the risk factors for EDs, however, the treatment of these diseases is very complicated and requires dietary, psychological and medical intervention. Methods: 233 primary and secondary school students aged 12 to 19 were surveyed using the EAT-26 (Eating Attitudes Test-26) questionnaire, the self-esteem Scale SES and the Cantril scale for life satisfaction. Results: Women, when compared to men, showed lower self-esteem, satisfaction with their appearance, body weight and their lives and at the same time a higher risk of eating disorders in all three areas. Low life satisfaction is often correlated with weight loss greater than 10 kg. Low self-esteem correlated positively with significant weight loss (>10 kg) and more frequent uncontrollable binge eating and exercising (more than 60 min a day) to influence appearance. People with low self-esteem were more likely to be treated for EDs. Subjects dissatisfied with their lives binged, feeling that they could not stop. Conclusion: The younger the person, the more likely they are to develop eating disorders. This is closely correlated with low self-esteem and negative life satisfaction. Men were more likely to be satisfied with their weight, appearance, and life, and were less likely to show ED symptoms.

Physical activity offers numerous physical and mental health benefits for individuals with disabilities, while nutrition plays a crucial role in maintaining bodily homeostasis. This study aimed to assess the relationship between body composition and dietary habits among physically active people with disabilities. Fifty-five participants aged 16 to 61, including 28 with disabilities and 27 without, were included in the study. The FFQ-6 questionnaire, Tanita body composition analyzer, and Stadiometer were utilized. No significant differences in BMI were observed between the two groups. However, individuals with disabilities showed higher body fat, metabolic age, or pulse values, whereas the control group exhibited higher muscle mass, muscle quality, body type, or bone mass. Participants with disabilities were more likely to consume vegetables (p = 0.004) and animal fats (p = 0.027), while those without disabilities were more inclined to consume fast food, instant products (p = 0.006), sweetened beverages (p < 0.001), and alcohol (p < 0.001). People with disabilities often have a higher percentage of body fat, cautioning against the consumption of processed fruits, dried fruits, fast food, and red meat. Conversely, in non-disabled individuals, frequent consumption of eggs, animal fats, sugar, and sweets is not recommended due to the potential for increased body fat, visceral fat, and higher BMI.

Obesity is a growing global health challenge, closely linked to chronic low-grade inflammation. This persistent, low-intensity immune response contributes to the development of metabolic, cardiovascular, and cancer-related diseases. A key player in this process is the gut microbiota. Dysbiosis, an imbalance in gut bacterial composition, disrupts metabolic function, weakens the intestinal barrier, and promotes the production of pro-inflammatory cytokines. In people with obesity, gut microbial diversity is reduced, and the ratio of beneficial to harmful bacteria shifts, affecting lipid metabolism and immune balance. Short-chain fatty acids, produced by gut bacteria, help maintain gut integrity and reduce inflammation. Butyrate, a major SCFA, also improves insulin sensitivity and may support obesity treatment. Diet plays a central role in shaping the gut microbiome. Western diets tend to promote dysbiosis and inflammation, while Mediterranean-style diets encourage the growth of beneficial bacteria. Targeted modulation of the microbiota through diet, probiotics, or medication emerges as a promising strategy for preventing and managing obesity.

(1) Background: Studies indicate that 45 to 95% of women suffer from painful periods. Despite frequent incidence, the problem is still underestimated. Menstruation-related ailments often correlate with high absenteeism at school and work, as well as limitation of social and scientific activity. The aim of this study was to assess the relationship between the size of the curvature, the mobility of the spine in the sagittal plane, and menstrual pain in young women. (2) Methods: The analysis included 224 women aged 18–26, mean of 21.56 ± 1.95, studying at the College of Medical Sciences of the University of Rzeszów. For this purpose, the measurement of the anterior–posterior curvature of the spine with a gravitational inclinometer, the Schober test and the authors’ questionnaire related to menstruation were used. (3) Results: The data analysis demonstrated a significant difference between the group with menstrual pain (MP) and the control group without pain (CG), where the angle of the lumbar sacral transition (p = 0.034), thoracolumbar transition (p = 0.044) and lumbar lordosis (p = 0.006) were statistically significantly lower in MP compared to CG. There were no significant differences in the measurement of the so-called smartphone hump and between the mobility of the lumbar spine and menstrual pain in any of the groups. (4) Conclusions: Women with menstrual pain are characterized by reduced lumbar lordosis and thoracic kyphosis, while sagittal mobility of the spine does not affect pain.

Background: Endometriosis is a chronic inflammatory disease marked by the presence of endometrial tissue outside the uterus. Main symptoms include pain in the sacrum, pelvis, and abdomen, occurring at various stages of the menstrual cycle or during intercourse. These symptoms can severely affect daily functioning and quality of life. Methods: The study involved 200 women aged 18–47, divided into two groups. The WHT group (N = 100) included women with endometriosis not receiving hormone therapy, and the HT group (N = 100) included women undergoing hormone treatment. An anonymous questionnaire was used, comprising a VAS, the FFQ-6 food frequency questionnaire, and questions regarding menstruation-related symptoms and effects. Results: Women in the HT group reported higher pain levels (Me = 8.0 vs. 7.0) and more frequent negative impacts on academic/work performance (p = 0.008) than the WHT group, who reported higher work attendance (p = 0.043). In the WHT group, consumption of sugar, honey (p = 0.019), sweet cereals (p = 0.023), and sweetened beverages (p = 0.036) was associated with absences and concentration difficulties (p = 0.010). In contrast, in the HT group, those reporting absences consumed more nuts and vegetables (p = 0.024; p = 0.003). Conclusions: Women with endometriosis undergoing hormone therapy report more severe pain and more frequent disruptions in daily functioning. Both hormone therapy and diet significantly influence the intensity of menstrual symptoms as well as the ability to function professionally and socially.

Background: Eating disorders are increasingly diagnosed in young women, particularly during adolescence. The recently described Anorexic Readiness Syndrome (ARS) is more common than full-blown anorexia. It has been identified in female athletes engaging in disciplines focusing on the aesthetics of the body, in women involved in recreational exercise and in those who are not physically active but strive to achieve the “perfect” figure. The study aimed to assess the severity and prevalence of ARS in women regularly engaging in body-shaping physical activity. Methods: The study included 659 women aged ≥ 14 years who engaged in regular body-shaping physical activity, provided informed consent to participate in the study (in the case of minors, also the consent of a parent or legal guardian), and had no diagnosed chronic diseases. The level of ARS was assessed using a questionnaire measuring attitudes toward food, supplemented with a specially designed survey consisting of 32 questions and a personal data form. Based on the frequency of body-shaping physical activity, participants were divided into two groups: the study group comprised women exercising ≥ 3 times per week (n = 301), while women exercising < 3 times per week constituted the control group (n = 358). The analyses examined the relationships between ARS, frequency of body-shaping physical activity, BMI, and menstrual irregularities. Results: Medium or high ARS level was identified in over 96% (n = 637) of the respondents. The level of ARS was significantly related to the allocation into the group (p = 0.034) and the weekly hours of physical activity (p = 0.011 in the control group; p = 0.020 in the study group). There was a correlation between ARS and menstrual irregularities (p = 0.001). Weak but significant correlations were identified for awareness of eating disorders (V = 0.20; p = 0.001), adherence to a special diet (V = 0.18; p < 0.001) and self-assessed health (V = 0.18; p < 0.001). Conclusions: Higher ARS levels were observed in women reporting greater weekly physical activity. No significant associations were found between ARS and body mass index or body weight. Medium and high ARS levels were significantly associated with self-reported menstrual disturbances, while most participants with elevated ARS were unaware of disordered eating risk.
