How common is Hypophosphatemia

Hypophosphatemia is typically asymptomatic and is present in up to 5% of patients. It is much more prevalent in alcoholism, diabetic ketoacidosis, or sepsis, with a frequency of up to 80%. The morbidity of hypophosphatemia is highly dependent on its etiology and severity.

Is low phosphate common?

In general, hypophosphatemia is rare. It’s more common in people who are hospitalized or admitted to intensive care units (ICUs). Between 2% and 3% of people admitted to the hospital, and up to 34% of those in ICUs, have this condition.

What level is considered hypophosphatemia?

Serum phosphate or phosphorus normally ranges from 2.5-4.5 mg/dL (0.81-1.45 mmol/L) in adults. Hypophosphatemia is defined as mild (2-2.5 mg/dL, or 0.65-0.81 mmol/L), moderate (1-2 mg/dL, or 0.32-0.65 mmol/L), or severe (< 1 mg/dL, or 0.32 mmol/L).

What is the most common cause of hypophosphatemia?

Hypophosphatemia is most often caused by long-term, relatively low phosphate intake in the setting of a sudden increase in intracellular phosphate requirements such as occurs with refeeding. Intestinal malabsorption can contribute to inadequate phosphate intake, especially if coupled with a poor diet.

How long does it take to recover from hypophosphatemia?

In this group, serum phosphate levels decrease to a nadir within approximately 2 days and recover in the following days. This early nadir is also described after cardiac surgery and in patients with diabetic ketoacidosis and the refeeding syndrome.

Can hypophosphatemia cause death?

Acute severe hypophosphatemia can cause serious neuromuscular disturbances, rhabdomyolysis, seizures, coma, and death.

What is the difference between hypophosphatasia and hypophosphatemia?

In hypophosphatasia, mineralization is disrupted affecting a number of tissues, including bone and teeth. With X-linked hypophosphatemia, an inability of the cells in the body to properly process phosphate causes circulating levels of phosphate to be low, resulting in problems with bone and tooth development.

Can diarrhea cause hypophosphatemia?

Hypophosphatemia resulting from poor intake is uncommon, because phosphorus is plentiful in the diet. It can occur, however, when an individual has been chronically and severely malnourished. Malabsorption of phosphorus is often secondary to inflammatory states, surgery, or diarrhea.

What type of doctor treats hypophosphatemia?

A nephrologist can help confirm the likelihood of phosphate wasting and can help assess the patient for causes of renal phosphate wasting.

What drugs cause hypophosphatemia?

Hypophosphatemia, defined as serum phosphate levels below 2.5 mg/dL (0.81 mmol/L), is frequently observed in the course of treatment with commonly used drugs, such as diuretics, bisphosphonates, antibiotics, insulin, and antacids.

How do you fix hypophosphatemia?

Treatment of hypophosphatemia is twofold: (1) correct any precipitating causes of hypophosphatemia, and (2) replace total body phosphates. Depending on the clinical situation, replacement options include dietary phosphate, oral phosphate preparations, and IV phosphate.

What is familial hypophosphatemia?

Familial hypophosphatemia is a term that describes a group of rare inherited disorders characterized by impaired kidney conservation of phosphate and in some cases, altered vitamin D metabolism.

Does diarrhea lose phosphorus?

Notably, chronic diarrhea has been shown to increase phosphate losses through the intestines. Certain medications are known to bind with phosphate, decreasing the available free ion to be absorbed via the small intestines into circulation.

Can Hypophosphatemia cause seizures?

Hypophosphatemia is a condition in which your blood has a low level of phosphorous. Low levels can cause a host of health challenges, including muscle weakness, respiratory or heart failure, seizures, or comas.

What does low phosphate feel like?

Low levels of phosphate rarely lead to symptoms of hypophosphataemia; rather symptoms usually result from the associated condition that causes hypophosphataemia. Very low phosphate levels can cause breathing difficulties, confusion, altered mental status, muscle weakness and muscle damage called rhabdomyolysis.

Does TPN cause hypophosphatemia?

Hypophosphatemia occurs frequently after initiation of TPN therapy despite phosphate supplementation. Provision of 13.6 mEq phosphate/liter prevents hypophosphatemia in most patients.

Is Odontohypophosphatasia genetic?

The adult form and odontohypophosphatasia typically are autosomal dominant disorders, but rarely autosomal recessive. Dominant genetic disorders occur when only a single copy of a non-working gene is necessary to cause a particular disease.

What is the ALPL gene?

The ALPL gene provides instructions for making an enzyme called tissue-nonspecific alkaline phosphatase (TNSALP). This enzyme plays an important role in the growth and development of bones and teeth. It is also active in many other tissues, particularly in the liver and kidneys.

How many babies are born with hypophosphatasia?

Severe forms of hypophosphatasia affect an estimated 1 in 100,000 newborns. Milder cases, such as those that appear in childhood or adulthood, probably occur more frequently. Hypophosphatasia has been reported worldwide in people of various ethnic backgrounds.

What is hyperphosphatemia?

Hyperphosphatemia—that is, abnormally high serum phosphate levels—can result from increased phosphate intake, decreased phosphate excretion, or a disorder that shifts intracellular phosphate to extracellular space.

Can hypophosphatemia cause pancreatitis?

Severe hypophosphatemia (<1.0 mg/dl) is a rarely reported complication of acute pancreatitis; when it does occur, it is typically attributed to alcohol abuse rather than the pancreatitis itself (1-5).

Does hypokalemia cause hypophosphatemia?

Dr. Vianna is now affiliated with Albany (NY) Medical Center. Severe hypokalemia, induced by the chronic ingestion of licorice and hydrochlorothiazide, appears to have caused a marked increase in phosphate clearance, a decrease in tubular reabsorption of phosphate, and hypophosphatemia.

What is symptomatic hypophosphatemia?

Patients with severe and/or chronic hypophosphatemia are more likely to be symptomatic. Weakness, bone pain, rhabdomyolysis, and altered mental status are the most common presenting features of persons with symptomatic hypophosphatemia. Occasionally, patients with mild hypophosphatemia may complain of weakness.

What are the symptoms of hyperphosphatemia?

Signs and symptoms of acute hyperphosphatemia result from the effects of hypocalcemia, with patients occasionally reporting symptoms such as muscle cramps, tetany, and perioral numbness or tingling. Other symptoms include bone and joint pain, pruritus, and rash.

How is Xlh diagnosed?

XLH is diagnosed based on a physical exam, blood tests, imaging tests such as X-rays , and family history . Specific factors considered for the diagnosis include: A slow growth rate and noticeable bowing of the legs or other skeletal abnormalities. Low levels of phosphate and high levels of FGF23 in the blood.

How does alcoholism withdrawal cause hypophosphatemia?

In addition, alcohol treatment is associated with refeeding, which further depletes phosphate, and the stress of alcohol withdrawal may create respiratory alkalosis, which exacerbates hypophosphatemia (see above).

Why do you get Hypophosphatemia in DKA?

Hypophosphatemia may be worsened during treatment of DKA because insulin causes a shift of phosphate into the cellular compartment and fluid replacement dilutes the phosphate concentration [1]. These factors frequently lead to mild to moderate hypophosphatemia in DKA patients.

Can Tums cause hypophosphatemia?

Hypophosphatemia has repeatedly been associated with phosphate-binding antacids. In fact, absorption of phosphate can be blocked by commonly used over-the-counter aluminum-, calcium- and magnesium-containing antacids.

Can spironolactone cause hypophosphatemia?

Pathologic changes in the parathyroid gland with hypercalcemia and hypophosphatemia have been observed in patients on prolonged thiazide therapy. Gynecomastia may develop in association with the use of spironolactone; physicians should be alert to its possible onset.

Can low phosphate cause anxiety?

Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change. In children, decreased growth and poor bone and tooth development may occur.

How does phosphate affect the heart?

Depletion of phosphate can lead to ventricular arrhythmias and elimination of ATP synthesis, resulting in reversible myocardial dysfunction. Hyperphosphatemia, observed mainly in patients with chronic kidney failure, is also associated with cardiac hypertrophy, which may worsen cardiac contractility and heart failure.
