Addison’s Disease Causes - What Leads to Adrenal Insufficiency?

Less tropic hormone secretion leads to less stimulation of cortisol secretion by cells of the In Cushing's disease, both ACTH and cortisol levels will be high. Weight gain or loss is generally an issue both during and after times of elevated stress. Heightened stress levels tend to cause imbalances in hormones like. High levels of adrenocorticotropic hormone are detected in the adrenal glands and Too little cortisol can be due to a condition called Addison's disease.

Negative Feedback Regulation of Hormone Release in the Hypothalamic-Pituitary Axis

There are some very rare syndromes several diseases that occur together that can cause autoimmune adrenal insufficiency. Sometimes referred to as multiple endocrine deficiency syndrome, APS is further categorized as type 1 or type 2. Symptoms start during childhood.

Almost any organ can be affected by autoimmune damage. Fortunately it is extremely rare—only several hundred cases have been reported worldwide. Conditions associated with APS type 1 include: Symptoms primarily develop in adults aged 18 to Conditions associated with APS type 2 include: Other causes of primary adrenal insufficiency include: Amyloidosis—protein build up in organs very rare Bleeding into the adrenal glands Cancer that spreads to the adrenal glands Infections bacterial, fungal, tuberculosis of the adrenal glands Surgical removal of the adrenal glands Secondary Adrenal Insufficiency: ACTH is made in the pituitary gland.

By far the most common cause of this type of adrenal insufficiency is chronic steroid use.

A decline in the concentration of ACTH in the blood leads to a reduction in the secretion of adrenal hormones, resulting in adrenal insufficiency hypoadrenalism. Adrenal insufficiency leads to weight loss, lack of appetite anorexiaweakness, nausea, vomiting, and low blood pressure hypotension. Because these symptoms are so general, the diagnosis is sometimes delayed or missed entirely.

For that reason, some clinicians believe the disorder to be more common than previously thought. Symptoms include weight loss, lack of appetite anorexiamuscle weakness, nausea and vomiting, and low blood pressure hypotension.

Low blood levels of sugar and dilutional hyponatremia low blood sodium levels may occur; however, blood potassium levels are typically normal as affected patients are deficient in glucocorticoids and not mineralocorticoids due to their intact renin-angiotensin-aldosterone system.

The pituitary hormone ACTH may be undetectable in blood tests, and the level of the adrenal hormone cortisol is abnormally low. Concentrations of hydroxycorticosteroids and ketosteroids, produced from the adrenal cortex, are also abnormally low in the urine.

Although males with this disorder usually have a normal hair pattern, females may have very little pubic and underarm axillary hair. Emotional symptoms may range from depression to psychosis. Also, there is a congenital present at birth form of ACTH deficiency that has been tracked to mutations of the T-box 19 TBX19 gene also referred to as TPIT on the long arm of chromosome one 1qq24 and the corticotropin releasing hormone CRH gene on the long arm of chromosome eight 8q The inheritance pattern is thought to be autosomal recessive.

Addison’s Disease Causes

Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. Human body cells normally have 46 chromosomes.

Pairs of human chromosomes are numbered from 1 through 22 and the sex chromosomes are designated X and Y. Males have one X and one Y chromosome and females have two X chromosomes. Chromosomes are further sub-divided into many bands that are numbered.

For example, chromosome 1qq24 refers to a region on the long arm of chromosome 1 between bands 23 and Similarly chromosome 8q13 refers to the band numbered 13 on the long arm of chromosome 8. The numbered bands specify the location of the thousands of genes that are present on each chromosome. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from the father and the mother. Recessive genetic disorders occur when an individual inherits the same abnormal gene for the same trait from each parent.

If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. The risk is the same for males and females.
