Causes of Hyperphosphatemia
Hyperphosphatemia, which refers to high levels of phosphates in the blood, can be attributed to various underlying factors. The primary cause is often linked to kidney failure or advanced renal insufficiency, where the kidneys fail to effectively filtrate and excrete phosphates from the body. Additionally, an overactive or underactive thyroid gland may contribute to the development of hyperphosphatemia.
Other potential causes include diabetic ketoacidosis, crushing injuries, certain medications, and severe infection. In rare cases, excessive oral intake of phosphate or the use of enemas containing phosphate can result in hyperphosphatemia.
Diagnosis of Hyperphosphatemia
Identifying hyperphosphatemia involves conducting bloodwork with a comprehensive chemistry profile. This procedure helps medical professionals confirm the presence of elevated phosphate levels in the blood. To make an accurate diagnosis, healthcare providers analyze various factors, including calcium and phosphate levels, urea, creatinine, and hormones related to the thyroid gland. These diagnostic tests not only help confirm hyperphosphatemia but also assist in identifying the underlying cause of the excessive phosphate levels.
