Guest guest Posted July 27, 2005 Report Share Posted July 27, 2005 I have had a strong craving for salt for as long as I can remember. Give me salt any day over sugar and I will be happy. I was talking with my mom yesterday who has supposedly got MS and she craves salt like me, preferable to sugar. It got me wondering and I did a search on Lyme and salt craving. There was info, but what kept coming up is adrenal fatigue and even 's Disease which is adreanl disfunction to the max. Salt cravings are usually due to low adelesterone. Remember the conversations about Benicar and ARBs like Benicar lowering Adelesterone even further? One of the articles I found said that. I wonder if salt cravings could be an indicator that you will not do well on Benicar? Salt craving can also be an indication of low magnesium, and aren't most of us low there? ================================================================= Your Adrenal HormonesThe adrenals, small glands located above each kidney, produce a number of importanthormones. The adrenals' inner medulla produces epinephrine and norepinephrine (adrenaline).Tumors of the adrenal medulla which produce excess epinephrine and norepinephrine are calledpheochromocytomas. Deficiencies of the adrenal medulla that reduce the levels of thesehormones do not give rise to clinical problems.Adrenals also contain an outer cortex, which produces hormones such as cortisol, aldosterone,testosterone, DHEA, DHEAS, androstenedione and estrogens. Cortisol and aldosterone are twoof the most important hormones the body makes. Excesses or deficiencies of these hormonesresult in important clinical problems. Cortisol, a glucocorticoid, is the stress hormone and isinvolved in weight control, infection fighting, quality of skin and bones, and heart function. Itslevels are the highest in the morning, and are increased by stress and severe illness. Too muchcortisol from any cause leads to Cushing's syndrome; the symptoms and signs of which includeweight gain, stretch marks, bruising, extra hair growth, irregular periods in women, loss ofmuscle, trouble sleeping and emotional problems, such as depression. Too little cortisol is partof the syndrome called 's disease, often marked by low energy, joint and abdominalpain, weight loss, diarrhea, fever, and electrolyte disturbances. If the adrenals are making toolittle cortisol, the pituitary compensates and makes more of the hormone, ACTH. If the pituitaryis not working, both ACTH and cortisol levels may be low. Aldosterone is the salt-retaining hormone and is a mineralocorticoid. Excess of aldosterone leadsto high blood pressure and low potassium. Deficiencies of aldosterone are much lessappreciated than deficiencies of cortisol, and lead to low blood pressure and high pulse,especially on standing, the desire to eat salt (salt-craving), dizziness or lightheadedness onstanding, and palpitations. Severe cases may lead to high potassium and low sodium in bloodtests. When the adrenal is not making aldosterone, renin, a kidney hormone, increases. Excessesof cortisol and aldosterone may occur independently, that is a patient may have only excessaldosterone, only excess cortisol, or excesses of both. Similarly, deficiencies of cortisol andaldosterone deficiencies may be independent.Many patients coming to see Dr. Friedman lately with symptom of fatigue and often symptomsof salt-craving, " cognitive fuzziness " , dizziness or lightheadedness on standing, or palpitationshave low blood levels of aldosterone. He explains the connection between low aldosterone levelsand fatigue as follows: with low aldosterone, the kidney loses salt, leading to low blood volume.This coupled with the idea that the leg veins don't constrict properly, leads to lower bloodvolume to the brain and fatigue and other symptoms. These patients often have a drop in theirblood pressure and an increase in their pulse when standing. They may also have decreasedblood flow to the brain when measured by SPECT scan. Aldosterone deficiency may be madeworse if patients restrict their salt intake.Soon-to-be-published research by Dr. Friedman shows a few patterns of abnormalities in therenin-aldosterone axis. A little more than half the patients with fatigue had low blood levels ofboth renin and aldosterone. This is called hyporeninemic hypoaldosteronism and is probably due --------------------------------------------------------------------- ----------- Page 2 to dysfunction of what is called the autonomic nervous system, which sends messages from thebrain to the kidneys. Other aspects of the autonomic nervous system have been found to bedeficient in chronic fatigue syndrome. About one-third of the patients were found to have lowaldosterone and high renin. This indicates a deficiency in the aldosterone production in theadrenals themselves, with a compensatory rise in the renin coming from the kidney. Thealdosterone defect can either be an isolated problem, or part of 's disease (often early's disease), in which both cortisol and aldosterone production are diminished. Theremaining patients (about one-sixth) had both high renin and high aldosterone. This is likely tobe a compensatory rise in both of these hormones as a reaction to a low blood volume, mostlikely due to an inability of the kidney to retain salt.Dr. Friedman recommends treating patients with an individualized combination of increased saltconsumption, a synthetic form of aldosterone called Florinef (fludrocortisone), or Midodrine(proamantine), a drug used to raise blood pressure. Salt is the most benign of the treatments. Salt tablets can be purchased in a drug store or a patient can add an extra teaspoon of salt to theirfood per day. Florinef comes in 0.1 mg pills and Dr. Friedman usually starts with 1/2 pill in themorning for a week or two and then goes up to 1 pill in the morning if no side effects occur. Themain side effects are headache and swelling in legs (edema). Midodrine comes in 5 mg pills andDr. Friedman usually starts with 5 mg pills in the morning and noon. He may go up to 2 pillsthree times a dayand sometimes needs to use both Florinef and Midodrine, as well as extra salt.The side effects of Midodrine include high blood pressure, itching, goosebumps, numbness andthe feeling of writing on your skin or scalp. Many of these side effects go away with use andboth drugs are unlikely to cause long term damage. Most patients taking Florinef and Midodrine,as well as extra salt report an improvement in their symptoms of palpitations anddizziness/lightheadedness on standing, while many report an improvement in fatigue andcognitive dysfunction. Licorice, available as a tea from Alvita, may help with mild cases.Dr. Friedman is doing further research on the renin-aldosterone axis and chronic fatiguesyndrome (CFS) in a study generously funded by the CFIDS (Chronic Fatigue and ImmuneDysfunction Syndrome) Association of America. He is also studying the effect of Viagra onsymptoms of CFS, with the idea that Viagra may improve blood flow to the brain.
