Thyroid disorder is an illness prevalent among the elderly. The objective of this study was to evaluate the nutritional status of individuals with thyroid dysfunction, both male and female. This study involved Sixty individuals, comprising Thirty with hyperthyroidism and thirty with hypothyroidism. Their ages varied from twenty to sixty years. All individuals evaluated were picked from Ahmed Maher Hospital in Cairo, Egypt. Data were obtained from patient interviews. Data on socioeconomic status and nutritional assessment was collected by a questionnaire, a 24-hour dietary recall method over three days, a food frequency questionnaire, and an evaluation of nutritional knowledge. Anthropometric assessments were conducted for all evaluated individuals, involving the assessment of thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) levels. The findings indicated that the weight of patients with hypothyroidism was greater than that of patients with hyperthyroidism. The results indicated that the average consumption of energy and macronutrients exceeded the Recommended Dietary Allowance (RDA) levels for the tested patients. Conversely, the intake of minerals (magnesium and calcium) among all examined individuals exhibited levels below the RDA. The average levels of thyroid hormones fall within the normal range; nevertheless, there were notable disparities in the blood concentrations of these hormones among hyperthyroidism and hypothyroidism. This study advocated for a nutrition education program addressing thyroid dysfunction. Furthermore, appropriate eating practices should commence early and persist throughout one's lifetime.
