Commnent allez-vous? J’ai écrit pour vous des recommandations que j’ai traduites en français. Je vous invite surtout à ne pas vous laisser effrayer par le texte et à ne pas vous laisser aller. Rappellez vous aussi qu’un grand nombre d’examens paracliniques sont entâchés d’erreurs, comme le rapporte mes deux pages sur la valeur de la cholestérolémie chez la personne âgée, surtout lorsqu’ils ne sont pas appuyés par la clinique.
Les examens à faire portent, souvent, des abbrévations en anglais, mais les médecins haïtiens peuvent les traduire pour toi

The kidneys excrete phosphate. Therefore, the most common cause of increased phosphate levels is the kidney's inability to get rid of phosphate. Hyperphosphatemia is also seen in people who have:
· Excessive dietary intake of phosphate (also from laxatives or enemas)
· Your body may have a deficiency in calcium or magnesium, or it may have too much Vitamin D.
· Severe infections can cause increased phosphate levels.
· Cell destruction - from chemotherapy, when the tumor cells die at a fast rate. This can cause tumor lysis syndrome.
· Problems with your breathing (respiratory acidosis)
· You may have elevated phosphate levels from prolonged exercise, which causes muscle damage. Certain athletes and distance runners may get this, called rhabdomyolysis.
· You may have problems with your thyroid, parathyroid gland, or other hormones, causing increased levels of phosphate in your blood
· Kidney failure
What are some symptoms to look for?
· Signs of hyperphosphatemia include an elevated blood phosphate level. Other electrolyte values are likely to be affected, depending on your disease.
· There are no symptoms of hyperphosphatemia. You may not know that your blood phosphate levels are elevated. The symptoms that you have are due to the underlying disease.
Toxicity
Elevated blood phosphorous levels are usually secondary to inadequate renal
filtration due to acute or chronic renal failure.
Imbalances in phosphate intake may contribute to negative calcium balance when
inadequate calcium intake is accompanied by excessive intake of phosphorous.
Elevations in serum phosphate following a meal will inhibit activation of vitamin
D which is necessary for stimulation of intestinal calcium absorption. In response
to diminished levels of calcitriol, additional amounts of parathyroid hormone are
secreted to compensate for interference with vitamin D activation by elevated
serum phosphate. This condition is described as a nutritional secondary
hyperparathyroidism which contributes to increased rates of bone turnover and
eventually to a reduction of bone mass and density.
The upper intake levels of phosphorous intake for both men and women are 4,000
mg daily until age 70 after which the daily maximum is reduced to 3,000 mg.
Dietary Sources
Good dietary sources of phosphorous are typically also rich in protein. These
foods are mainly milk, meat, nuts, legumes, and grains. Additional dietary
sources of phosphorous are listed in the table below.

Board of the Institute of Medicine is 3-4 grams daily for adults. See table below for
