HPA axis that is more conditioned for long-term stressors. The physiological response process begins when the hypothalamus triggers a factor that inhibits the pituitary gland to secrete ACTH. The adrenal cortex is then aroused by ACTH to secrete cortisol‚ which increases blood sugar levels and metabolism. When metabolic activity is increased in the hippocampus‚ neurons become more sensitive to toxins or over-stimulation. This is a slow process‚ but in the end it helps the body defend itself in

onto our arms like this. Physiologically‚ there are differences on two key hormones: testosterone‚ which is the dominance hormone‚ and cortisol‚ which is the stress hormone. So what scientists find is that people who feel powerful‚ full of energy and positive have high testosterone and low cortisol. People who feel low‚ powerless and stressed have high cortisol level and low testosterone. The scientists have this evidence‚ that the body can shape the mind. Power posing for a few minutes can really

Cushing Disease Causes: Cushing’s disease is a hormonal disorder caused by prolonged exposure of the body’s tissues to excessive levels of the hormone cortisol. This disease in comparison is rare and the most commonly affected victims by this disease are adults aged 20 to 50. It’s estimated 10 to 15 of every million people are affected each year. Symptoms: Symptoms may vary‚ but most victims have upper body obesity‚ rounded face‚ increased fat around the neck‚ and thinning arms and legs. Children

Links have been found between biochemical‚ genetics and hormonal imbalances with depressed people. In the biochemical explanation‚ a link has been found between neurotransmitter imbalances and depression. Serotonin is associated with pleasure and mood.

disease is a disorder of the adrenal glands. It is also known as hypocortisolism or adrenal insufficiency. The disease occurs when your adrenal glands do not produce sufficient amounts of certain hormones. The adrenal glands do not produce enough cortisol and more often than not‚ insufficient amounts of aldosterone. Autoimmune disease can be attributed to approximately 70 percent of the cause for Addison’s disease. The autoimmune system mistakenly attacks the adrenal glands and kills the outer

group of symptoms that occur when a persons’ cortisol levels are too high (known as hypercortisolism) for too long. The majority of people have Cushing’s syndrome because they are regularly taking certain medicine(s) that continually add too much cortisol to the body. Doctors call this an “exogenous” (outside the body) cause of Cushing’s syndrome. Other people have Cushing’s syndrome because something is causing the adrenal gland(s) to overproduce cortisol.5 Doctors call this an “endogenous” (inside

STRESS COPING MECHANISMS AMONG YOUTH (PGDM STUDENTS) 1. INTRODUCTION A word which we consistently heard and feared from the day we thought of doing management studies is “STRESS”.

Every individual has his own methods for coping up with the stress; like playing games‚ working out in gym‚ listening to music‚ doing yoga‚ chatting with friends etc.

rare but well-studied enzymatic errors of metabolism with deficient levels of different enzymes involved in the synthesis of cortisol (hydrocortisone). CAH comprises a group of disorders resulting from defective synthesis of adrenal corticosteroids. Lack of glucocorticoids‚ especially cortisol‚ causes various kinds of metabolic problems. The response to low levels of cortisol is increased production of corticotropin (ACTH). Lack of mineralocorticoids‚ primarily aldosterone (steroid hormone)‚ causes
