This document discusses hypophosphatemia, its causes, clinical consequences, and treatment approaches. It begins by defining the normal phosphate range and what constitutes hypophosphatemia. Pseudohypophosphatemia is also introduced. Causes of hypophosphatemia include decreased intake, excessive loss, and redistribution from extracellular to intracellular spaces. Clinical consequences range from mild symptoms to organ dysfunction depending on severity. Treatment involves oral or IV phosphate replacement depending on phosphate levels and symptoms. Monitoring is needed to avoid complications. The document also explores phosphate regulation and transport in the kidney as well as factors involved like FGF-23, PTH, and vitamin D metabolites.
This document discusses hyperphosphatemia and its causes and effects. It begins by defining hyperphosphatemia as a serum phosphate level greater than 5.2 mg/dL. It then discusses pseudohyperphosphatemia which can result from conditions like multiple myeloma or hyperlipidemia. The document outlines the clinical features of hyperphosphatemia which can include hypocalcemic symptoms. It also discusses acute phosphate nephropathy and treatments which involve restricting phosphate intake, using phosphate binders, and dialysis for more severe cases. The regulation of phosphate excretion and potential causes of hyperphosphatemia both renal and non-renal are explored in detail.
This document summarizes calcium, phosphate, and magnesium metabolism. It discusses that these minerals have important intracellular and extracellular functions regulated by hormones like PTH and vitamin D. The majority of calcium is stored in bone, while phosphate and magnesium also have roles in cell structures and energy processes. Tight homeostasis maintains mineral levels in the blood and body through balances of absorption, excretion, and bone remodeling. Disorders can develop if these processes are disrupted.
The document discusses phosphate homeostasis and hypophosphatemia. Phosphate is essential for cell function and structure. Hypophosphatemia can be caused by intracellular shifts, increased urinary excretion, decreased absorption, or low intake. Severe hypophosphatemia can cause muscle weakness, respiratory issues, and neurological problems. Treatment involves correcting underlying causes and replacing phosphate through diet, oral supplements, or intravenous administration depending on severity.
Hypophosphatemia is a condition defined by a serum phosphorus level lower than 2.7 mg/dL, which can be caused by insufficient phosphorus intake, increased phosphorus excretion, or intracellular shifts. Symptoms include decreased cardiac and respiratory function, weakness, impaired reflexes, bone abnormalities, irritability, and bleeding issues. Treatment involves monitoring for symptoms, discontinuing contributing medications, supplementing with phosphorus and vitamin D orally or intravenously, careful movement to prevent fractures, and dietary adjustments to intake phosphorus-rich and limit calcium-rich foods.

HR (Hypophosphatemic Rickets) is caused by a lack of phosphate in the body, which leads to rickets. Phosphate levels are regulated by vitamin D, parathyroid hormone, and fibroblast growth factor 23 (FGF23). Mutations in genes like PHEX, FGF23, and DMP1 disrupt this regulation and cause excessive phosphate wasting, resulting in low phosphate levels and rickets. The document discusses the roles of these genes and regulators in detail, as well as approaches to identify mutations in PHEX, FGF23, and DMP1 through DNA extraction and sequencing.
This document discusses hyperphosphatemia, which occurs when phosphate levels in the blood are abnormally high. It provides information on the causes of hyperphosphatemia, which include kidney disease, and discusses guideline target levels and treatment options. Treatment involves phosphate restriction, phosphate binders such as aluminum hydroxide, calcium salts, and newer non-calcium binders. Novel therapies being researched include nicotinamide and iron-based compounds. The goal is to manage phosphate levels through diet, medication and dialysis to prevent complications in patients with chronic kidney disease.

Calcium & phosphorus metabolism and its applied aspectsdrshyam222
This document summarizes calcium and phosphorus metabolism. Calcium is essential for bone structure, nerve function, muscle contraction and more. The body tightly regulates calcium levels through hormones like PTH and calcitriol. Disorders occur when levels are too high or low, impacting bones, kidneys and other organs. Phosphorus also has key roles and is regulated similarly, with deficiencies or excesses also causing health issues. A variety of diseases like rickets, osteomalacia and osteoporosis result from imbalances in calcium and phosphorus metabolism.
This document discusses calcium and phosphorus regulation in the body. It covers calcium and phosphorus metabolism, factors that regulate them, and their roles in tooth mineralization. Calcium is the most abundant mineral and is essential for skeletal structure, muscle function, nerve impulses, and other physiological processes. Homeostasis of calcium is maintained through dietary intake, absorption in the gut, and regulation by parathyroid hormone, calcitonin, vitamin D, and kidneys.
Calcium and phosphate metabolism is tightly regulated in the body. Calcium is mainly stored in bones while phosphate is found intracellularly and extracellularly. Vitamin D, parathyroid hormone, and calcitonin control calcium and phosphate levels by impacting absorption in the gut and kidneys. An imbalance can result in hypercalcemia with symptoms like nausea and fatigue, or hypocalcemia which can cause tetany.
Calcium is essential for many physiological processes in the body. It makes up 1-1.5% of total body weight, with 99% located in bones and teeth. Dietary sources include dairy products, eggs, fish, and leafy greens. The recommended daily intake is 500 mg for adults and 1200 mg for children. Calcium is absorbed in the duodenum and jejunum through an active transport process requiring energy and carrier proteins. Homeostasis is maintained by calcitriol, parathyroid hormone, and calcitonin which regulate absorption from the intestine and resorption from bones. Imbalances can cause hypercalcemia with symptoms like confusion and arrhythmias, or hypocalcemia/
This document provides an overview of calcium, including its distribution in the body, sources, functions, dietary requirements, absorption and excretion. Key points discussed include:
- Calcium is mainly found in bones, with 99% located in the skeleton. Its main functions are structural support and muscle/nerve signal transmission.
- Dietary calcium recommendations vary by age but adults generally need 1000-1500mg per day. Major sources include dairy products.
- Calcium absorption occurs primarily in the small intestine and is regulated by parathyroid hormone, calcitonin, and vitamin D. Around 30-40% of dietary calcium is typically absorbed.
- Homeostatic control of calcium levels involves a balance between intestinal absorption
Calcium is essential for life and health from birth to old age. It plays key roles in bone and teeth development, muscle function, blood clotting, and nerve signaling. Most calcium in the body is stored in bones and teeth. Calcium deficiency can cause over 100 diseases and symptoms vary by age. The document recommends daily calcium intake amounts and lists those who may need supplements. It describes different calcium supplement types and highlights the advantages of TIENS' amino acid chelated calcium supplements which have high absorption rates and no side effects.
1) Calcium is essential for muscle contraction, nerve conduction, hormone release, and blood coagulation. The daily intake is approximately 1000mg, found in foods like milk, cheese, fish, and beans.
2) Calcium is absorbed in the small intestine through both passive diffusion and active transport involving vitamin D. Around 30-80% is absorbed depending on dietary intake.
3) Calcium levels in the body are tightly regulated by parathyroid hormone, vitamin D, and calcitonin which act on the intestines, bone, and kidneys to influence absorption, resorption, and excretion.
