Adrenal steroid hormones ppt

Cells of the zona fasciculata and zona reticularis lack aldosterone synthase (CYP11B2) that converts corticosterone to aldosterone, and thus these tissues produce only the weak mineralocorticoid corticosterone. However, both these zones do contain the CYP17A1 missing in zona glomerulosa and thus produce the major glucocorticoid, cortisol. Zona fasciculata and zona reticularis cells also contain CYP17A1, whose 17,20-lyase activity is responsible for producing the androgens, dehydroepiandosterone (DHEA) and androstenedione. Thus, fasciculata and reticularis cells can make corticosteroids and the adrenal androgens, but not aldosterone.

Depletion and dysregulation of adrenal hormones such as cortisol and adrenaline are the primary symptomatic drivers of Adrenal Fatigue and crashes. Repeated crashes over time will invariably further weaken the adrenal glands. While the intensity of each crash will increase as Adrenal Fatigue increases, it is not a linear progression clinically. Many in Stage 1 and Stage 2 Adrenal Fatigue are not aware of their impending problems. Their daily activities will remain unchanged, as there is sufficient adrenal reserve to compensate for any transient energy low.

Patients with congenital adrenal hyperplasia usually have to take lifelong steroid medication. Current treatments try to mimic normal biology as much as possible, but are not perfect. The evidence suggests that if well treated during childhood, most patients with congenital adrenal hyperplasia will reach a normal adult height but probably be a little shorter than would have been predicted if they did not have the disorder. Fertility is reduced in some patients but there are an increasing number of options for helping patients achieve fertility. Reconstruction genital surgery might be required in older girls with ambiguous genitalia. Maintaining the right balance of steroids is important during adult life to avoid the complications of osteoporosis , obesity and hypertension.
