Brief or mild hypoglycemia produces no lasting effects on the brain, though it can temporarily alter brain responses to additional hypoglycemia. Prolonged, severe hypoglycemia can produce lasting damage of a wide range. This can include impairment of cognitive function, motor control, or even consciousness. The likelihood of permanent brain damage from any given instance of severe hypoglycemia is difficult to estimate and depends on a multitude of factors such as age, recent blood and brain glucose experience, concurrent problems such as hypoxia , and availability of alternative fuels.
Cortisol supplements should only be taken for cases of severe cortisol deficiency, caused by serious disorders such as Addison’s or tuberculosis. If synthetic cortisol is taken when low cortisol levels are not severe enough to warrant it, this can result in a loss of natural cortisol production in the adrenal glands. Patients who see a decrease in their adrenal gland’s natural cortisol production will actually need to take extra cortisol during times of particular stress or activity, such as an illness, to make up for the lowered levels.
Potassium is a mineral that harbors electrical properties when it is dissolved in the fluid part of the blood and, as such, it is classified as an electrolyte. It is a nutrient that is critical to life as it is required for the proper functioning of cells, including the cells of the heart muscle. It works closely with its cousin sodium - another electrolyte – in maintaining the body's proper balance of fluids and acid-base. More specifically, potassium controls the amount of fluid inside cells while its cousin sodium maintains the balance of fluid outside cells. Potassium aids in proper muscle contraction and helps to keep the heart thumping regularly. It is also essential for conducting nerve impulses, aids in energy metabolism , and it even helps to maintain normal blood pressure. In fact, evidence suggests that diets high in potassium may help to protect against hypertension, strokes, and cardiovascular disease.
