What causes hypophosphatemia?
Acute hypophosphatemia is usually the more severe and common type of hypophosphatemia seen in clinical settings. Its causes include: 1 Recovery from diabetic ketoacidosis. Diabetic ketoacidosis happens when someone mismanages their diabetes or might not realize they have it. It is a state that the body goes into when it is unable to produce enough insulin. Insulin is what helps your body break fat down and burn it as fuel. When you go into diabetic ketoacidosis, you have a buildup of acids in your bloodstream, leading to loss of consciousness or even death. 2 Chronic Alcoholism. It is believed that over time, alcoholism hampers your kidney’s ability to absorb phosphorus fully. This is one of the most common causes of hypophosphatemia. Fifty percent of people who are hospitalized due to alcoholism develop hypophosphatemia within the first three days of their hospitalization. 3 Burns. Phosphate is a source of intracellular energy, and when someone experiences a severe burn, their phosphate levels dip dangerously low. Therefore, patients must receive supplemental phosphate to stay healthy. 4 Respiratory alkalosis. This is a decreased amount of carbon dioxide pressure without increased bicarbonate. It usually happens when you hyperventilate or simply breathe in and out too quickly. Respiratory alkalosis causes acute hypophosphatemia because your cells naturally begin to shift around the phosphate stores in your bones. This cause of acute hypophosphatemia is different than the other causes because it will immediately return to normal once the hyperventilation stops.#N#

Overview
Starvation
- Phosphorus deficiency is rare. Even when people don’t get enough of this mineral in their diets, t…
If you are deficient in other vitamins — like vitamin D — you may also have more trouble absorbing phosphorus and other minerals, like calcium, because of how they work together.
Diabetes
- Diabetes can also lead to a deficiency, especially for people recovering from an episode of diabetic ketoacidosis. This means that the body isn’t producing enough insulin and can’t break fat down as fuel. As a result, acids build up in the blood, which can cause a phosphorus deficiency.
Alcoholism
- Alcoholism may lead to malnutrition as well. As a result, people with alcoholism may develop nutritional deficiencies, including hypophosphatemia. Deficiency may be particularly likely in people who are hospitalized due to alcohol abuse.
Anorexia
- Individuals who are in treatment for eating disorders like anorexia may be on refeeding treatments. If these treatments are high in calories but too low in phosphorus, a deficiency may arise.
Inherited disorders
