Nowadays, due to hectic modern lifestyle, irregular eating habits, mental stress and lack of sleep, most of the people are suffering from some health problem or the other. Often people feel extreme fatigue, lethargy, weakness and lack of energy in the body after waking up in the morning. If this fatigue does not leave you even after taking rest and complete sleep and along with it your weight has also started decreasing rapidly, then it can be difficult to ignore it as just normal weakness or the effect of age. According to medical science and health experts, such symptoms indicate the deficiency of 'Cortisol', a very important hormone secreted by the adrenal glands in our body. Cortisol is also called the 'stress hormone' of our body, which plays the most important role in dealing with physical stress, controlling blood pressure, controlling metabolism and maintaining energy in the body. When the level of this hormone falls far below normal, the entire internal balance of the body begins to deteriorate. Rapid weight loss, constant dizziness and low blood pressure: Major serious symptoms of cortisol deficiency. When there is cortisol deficiency in the body (which in medical language is also considered a disorder related to adrenal insufficiency or addiction disease), many types of physical changes and serious symptoms start appearing. The first and foremost symptom is that the affected person feels extreme weakness and fatigue throughout the day, making it difficult for him to carry out normal daily activities. Apart from this, sudden rapid weight loss without any dieting or going to the gym (Unexplained Weight Loss), loss of appetite, constant pain in the muscles and weakening of the digestive system are its common signs. Cortisol works to control our blood pressure, hence due to its deficiency, the patient's blood pressure often remains very low, due to which he may feel dizzy, lightheaded or faint when he wakes up suddenly. In many cases, skin color becoming dark or dull (Skin Hyperpigmentation), mood swings, mental problems like excessive anxiety or depression can also be the result of this hormonal imbalance. Get rid of this problem by getting your medical examination and hormonal test done on time, improving lifestyle and eating right. If you or any member of your family is suffering from similar unexplained fatigue, weakness and weight loss problem for a long time, then do not ignore it at all and immediately consult a good endocrinologist or general physician. Doctors recommend serum cortisol levels and ACTH stimulation test through blood tests to accurately diagnose this condition. With timely correct diagnosis, this condition can be easily treated. To control this hormonal imbalance naturally, it is very important to bring positive changes in your lifestyle. Get enough sleep, practice yoga and pranayam to reduce stress, and include fresh fruits, green vegetables, adequate amounts of water, and food containing electrolytes in your diet. Avoid taking supplements of any kind without consulting a doctor, as the safest and most effective way to treat hormonal problems is under professional medical supervision.
