Lose Weight with Cortisol Control

The hormone cortisol has gained extensive attention as the ‘stress hormone’. It is released in the body during stressed or agitated states. But besides being a marker of stress levels, it is required for the functioning of almost all parts of the body. An excess or deficiency of this crucial hormone can also lead to various physical symptoms and diseases.

Cortisol is produced in the adrenal glands of the body. It is a corticosteroid hormone that is synthesised in the zona fasciculata of the cortex of the adrenal glands. Cortisol is its main secretion, even as the adrenal cortex also produces aldosterone (in the zona glomerulosa) and some sex hormones (in the zona reticulosa).

The functions of cortisol include assistance in the regulation of blood pressure and cardiovascular function, besides regulation of the use of proteins, carbohydrates, and fats in the human body. Chronic stress can lead to cortisol levels rising and remaining persistently higher than normal levels. This can lead to alterations in metabolism and affects your weight.

The main purpose of the glucocorticoids, which includes cortisol, is to help protect the body against infection. This is mainly done by normally altering processes, which lead to an increase in the pathogens' growth or their adverse effects and then declining when under attack. Cortisol is meant for intestinal diseases like diarrhoea and also for others like corticosterone serum disease.

Potassium loss is one of the most serious aspects of intestinal diseases. The electrolyte capabilities of cortisol are oriented toward conserving potassium. Low cell potassium reduces adrenal synthesis of cortisol, but not corticosterone. Such as to survive during intestinal disease, sodium, water, glucose, amino acids, chloride, hydrogen ion, copper, and numerous others are controlled by cortisol.

There are diurnal variations in the amount of cortisol present in the serum. The highest levels are present in the early morning, and levels are lower in the evening, several hours after the onset of sleep. From the retina, data about the light/dark cycle reach the paired suprachiasmatic nuclei in the hypothalamus. In connection with abnormal ACTH levels, clinical depression, psychological stress, and such physiological stressors as hypoglycemia, illness, fever, trauma, surgery, fear, pain, physical exertion or extremes of temperature, changed patterns of the serum cortisol levels have been observed. Even though a given person tends to have consistent rhythms, there is also significant individual variation.

The effects of cortisol being secreted into the bloodstream include an increase in blood pressure and glucose concentrations. It also leads to an increase in the glycogen formation in the liver. Bone formation and the functioning of the immune system are inhibited by the release of cortisol.

The secretion of corticotropin releasing hormone (CRH) is also inhibited by the release of cortisol, resulting in feedback inhibition of ACTH secretion. When animals are exposed to chronic stress, this normal feedback system may break down, according to some researchers.

About 96% of serum cortisol is bound to proteins including corticosteroid binding globulin (CBG), and albumin. The cortisol that is free is available to most receptors.

Cortisol has extensive actions in normal release that help restore homeostasis after stress. It mobilises energy reserves by acting as a physiological antagonist to insulin by promoting breakdown of carbohydrates, lipids, and proteins. Also, the responses of immune and inflammatory cells to stress are attenuated by cortisol.

The basis for the physiological consequences of chronic stress is formed by these normal endogenous functions. Secretion of cortisol, if prolonged, can lead to muscle wastage, hyperglycemia, and suppression of immune / inflammatory responses. Extended use of glucocorticoid drugs leads to the same sequelae.

If the cells in the hippocampus are exposed to cortisol over an extended period of time, it can lead to the cells being damaged. This, in turn, can lead to impaired learning. However, it is believed that exposure to cortisol over the short-term helps to create memories. In fact, this is the proposed mechanism for preservation of flash bulb memories.

The main glucocorticoid produced by the adrenal cortex gland is Cortisol. Out of the total cortisol secreted, 90% of the cortisol in circulation is bound to protein. The most prominent of these proteins is cortisol-binding globulin (CBG). Cortisol's major physiological actions are:

• Augment hepatic gluconeogenesis
• Add to hepatic glycogenolysis
• Enhance protein catabolism
• Restrict ACTH secretion through a negative feedback mechanism
• Keeping the blood pressure steady by sensitising arterioles to the action of noradrenaline
• Renal excretion
