In patients with anorexia nervosa, starvation, vomiting, laxative abuse, and exercise all contribute to a negative phosphate balance. Loss of phosphate via stool and urine, in addition to low intake during periods of accelerated growth (puberty), can cause symptoms of phosphate depletion.

What protein in blood is low in anorexia?
Medical findings in 1026 consecutive adult inpatient-residential eating disordered patients. Low prealbumin is a significant predictor of medical complications in severe anorexia nervosa.
Do anorexics have low sodium levels?
The most frequent electrolyte imbalances seen in anorexia are hyponatremia (a low concentration of sodium ions in the bloodstream) and hypokalemia (a low concentration of potassium ions).
Why does anorexia cause low WBC?
Essentially, faced with limited caloric resources, the body cannot sustain normal bone marrow function. As a result, one of the red flags to watch out for in standard blood tests is a low white blood cell count.
Can anorexia cause elevated liver enzymes?
HealthDay News — For adults with severe anorexia nervosa (AN), elevated liver enzymes are relatively common and are associated with lower body mass index (BMI) and hypoglycemia, according to research published online in the International Journal of Eating Disorders.
Can anorexia cause high iron levels?
Despite presumably reduced iron intake, we have observed and confirmed that raised ferritin concentration in the absence of infection/inflammation is quite common in patients with anorexia nervosa.
Can anorexia cause low platelets?
Platelet distribution width values significantly correlated with the disease duration and rate of body weight loss in the anorectic patients. Anorexia nervosa in adolescents is associated with a decrease in PLT along with an increased PDW, which may be an indicator of dysregulated thrombopoiesis.
Why does starvation cause hypophosphatemia?
Phosphorus is required for glucose metabolism to produce phosphorylated intermediates of glycolysis such as adenosine triphosphate and 2,3 diphosphoglycerate. The combination of cellular uptake of phosphorus together with depletion of total body stores during starvation causes extracellular hypophosphatemia.
Why do anorexics have low potassium?
Inpatients with anorexia nervosa presumably have a higher risk of developing hypokalemia because they suffer from severe malnutrition and are refed [21], in which the insulin surge resulting from glycemia during the refeeding process causes a substantial intracellular uptake of potassium and phosphorus [20].
Does anorexia cause low blood sugar?
Food restriction and excessive exercise enacted during anorexia leads to the depletion of glycogen (a form of energy storage), resulting in abnormal glucose metabolism and hypoglycemia (very low levels of blood sugar) (Mayo Clinic, 2018).
Can anorexia cause metabolic acidosis?
The onset of a metabolic acidosis in a patient with anorexia nervosa remains very rare, but also exceptionally severe and unknown to physicians. To our knowledge, this is the first reported case of starvation-induced metabolic acidosis in a non-diabetic adolescent with anorexia nervosa.
Can malnutrition cause low WBC?
Vitamin and mineral deficiencies Chronic malnutrition and alcoholism can also result in these deficiencies, and can therefore also be a cause of low WBC.
Can anorexia cause low hemoglobin?
Yes. Anorexia is an eating disorder that can bring about anemia. People who experience anemia lack enough healthy red blood cells to carry oxygen to body tissues.
Do anorexics have low WBC?
An estimated one-third of anorexic patients have mild anemia (low red blood cell count). Leukopenia (low white blood cell count) occurs in up to 50 percent of anorexic patients.
How does malnutrition affect liver enzymes?
Malnutrition affects liver cells and causes liver enzyme imbalances. Several studies have shown that malnutrition increases the levels of liver enzymes such as ALT and AST in patients. These changes have been reported in different degrees of malnutrition.
What happens to the liver in anorexia?
Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur.
Does starvation increase liver enzymes?
Although most cases are caused by refeeding syndrome (1-3), persistent starvation can also cause an exacerbation of liver enzyme levels (4-6).
Does anorexia cause low red blood cells?
Anemia is a type of disorder which occurs when the red blood cell count in the body is low. This disorder can occur in those with an eating disorder such as anorexia as a result of an unhealthy or nonexistent diet.
Can malnutrition cause high ferritin?
Severe protein-energy malnutrition is significantly associated with increases in serum ferritin levels (Figure 1).
Is anemia common with anorexia?
Anorexia Nervosa and Anemia 21 to 39% of those that struggle with anorexia nervosa are diagnosed with anemia [4]. This relationship is attributed to the nutritional deficiencies that result due to food and fluid restriction.
How does anorexia cause hyponatremia?
Hyponatremia can also be seen in severe restrictive eating disorders due to decreased ability of the kidney to excrete free water as a result of low nutritional intake. Without enough food or solutes, even a fairly normal amount of water intake can lead to hyponatremia if the body retains too much of it.
Why do electrolytes drop in refeeding syndrome?
When you begin refeeding, your cells demand these electrolytes to metabolize the food. This causes a severe shift in your body chemistry. The electrolytes you have move rapidly from your blood into your cells. But because you don’t have enough, this shift leaves low levels of them in your blood.
Why are my phosphate levels high?
If your test shows you have high phosphate/phosphorus levels, it may mean you have: Kidney disease. Hypoparathyroidism, a condition in which your parathyroid gland doesn’t make enough parathyroid hormone. Too much vitamin D in your body.
Does weight loss affect WBC?
Conclusion— This study concludes that acute weight loss can result in changing the level of white blood cells which are determined in immunity system and related disease.
Can anorexia cause neutropenia?
Mild neutropenia is a frequent and adaptive consequence of undernutrition in anorexia nervosa. Severe neutropenia associated with pancytopenia is a severity criteria that may evolve to gelatinous bone marrow.
