These reactions are coordinated by many processes, and one of them is the secretion of cortisol. This hormone is produced in the adrenal glands and is a key element of the protective response to stress. Normally, it helps to adapt, but if it is produced too much or too little, this is reflected in the general well-being and health. An analysis of cortisol allows you to determine whether this system is working correctly and whether chronic fatigue or irritability is a consequence of hormonal imbalance.<\/p>\n<h2 data-start=\"794\" data-end=\"817\"><strong data-start=\"797\" data-end=\"817\">What is cortisol?<\/strong><\/h2>\n<p data-start=\"819\" data-end=\"1148\">Cortisol is a hormone that regulates the body&#039;s response to stress, controlling blood sugar levels, blood pressure, metabolism, and immune function. Its levels naturally fluctuate throughout the day, peaking in the morning and declining toward evening. These daily fluctuations must be taken into account when interpreting test results.<\/p>\n<h2 data-start=\"1150\" data-end=\"1183\"><strong data-start=\"1153\" data-end=\"1183\">Indications for taking the analysis<\/strong><\/h2>\n<p data-start=\"1185\" data-end=\"1358\">A doctor usually orders a cortisol test if they suspect adrenal gland pathology or hormonal disorders.
