A number of electrolyte abnormalities have been reported in association with eating disorder including hypokalaemia, hyponatraemia, hypomagnesaemia, hypophosphataemia, hypocalcaemia and hypercalcaemia.

Can anorexia cause hypercalcemia?
Anorexia nervosa can cause significant renal problems, some of which may have contributed to the development of nephrocalcinosis in our patients. Electrolyte disturbances include hypokalaemia, hyponatraemia, hypercalcaemia, hypomagnesaemia and hypophosphataemia.
Can malnutrition cause hypercalcemia?
Hypercalcemia without elevated ionized calcium can occur in hyperalbuminemia, severe dehydration, or in multiple myeloma with a calcium-binding paraprotein. In hypoalbuminemia due to severe malnutrition or chronic liver disease, total serum calcium may be normal with elevated ionized calcium.
What is the most common medical complication of anorexia?
Cardiac. Bradycardia (pulse <60) and hypotension are among the most common physical findings in patients with anorexia nervosa, with bradycardia seen in up to 95% of patients.
Which disease or disorder is most likely associated with hypercalcemia?
Hypercalcemia is usually a result of overactive parathyroid glands. These four tiny glands are situated in the neck, near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and taking too much of calcium and vitamin D supplements.
Can hypercalcemia cause altered mental status?
Hypercalcemia is known to cause neuropsychiatric dysfunction. In mild cases, patients may present with anxiety, depression, and cognitive changes, while altered mental status, psychosis, confusion, lethargy, and coma hallmark severe hypercalcemia [1].
What does anorexia do to bones?
Loss of bone density makes bones less compact and more likely to break. When doctors use a bone mineral density scan, they will see that the bones of anorexic patients may be misshapen, loose material instead of circular, tight, dense material. In fact, bone fractures are extremely common in those with anorexia.
What causes hypercalcemia?
Overactive Parathyroid Glands (Hyperparathyroidism) Overactive parathyroid glands are the most common cause of hypercalcemia. When these glands are working right, they release parathyroid hormone (PTH) when your blood calcium levels get low.
What endocrine disorder can cause hypercalcemia?
Endocrine diseases that may cause hypercalcemia and hypocalcemia include hyperparathyroidism, hypoparathyroidism, thyroid disorders, hyperadrenocorticism, hypoadrenocorticism, and less commonly pheochromocytoma and multiple endocrine neoplasias.
Can dehydration cause hypercalcemia?
Severe dehydration is known to cause mild or transient hypercalcemia due to a decrease in fluid volume that affects calcium excretion via the kidneys [15].
Is 10.6 calcium level too high?
Your blood calcium level would be considered high if it surpasses the upper limit of the normal range, meaning it is greater than 10.3 mg/dl.
How long can you survive with hypercalcemia?
Unfortunately, cancer-related hypercalcemia has a poor prognosis, as it is most often associated with disseminated disease. Eighty percent of patients will die within a year, and there is a median survival of 3 to 4 months.
What are 3 health risks associated with anorexia?
- Anemia.
- Heart problems, such as mitral valve prolapse, abnormal heart rhythms or heart failure.
- Bone loss (osteoporosis), increasing the risk of fractures.
- Loss of muscle.
- In females, absence of a period.
- In males, decreased testosterone.
- Gastrointestinal problems, such as constipation, bloating or nausea.
What other diseases can anorexia cause?
- Liver problems.
- Gallstones.
- Slow metabolism.
- Osteoporosis.
- Heart disease.
- Kidney problems.
- Dehydration.
- Muscle wasting.
Which eating disorder is most associated with electrolyte imbalances?
In anorexia nervosa, under-nutrition and weight regulatory behaviours such as vomiting and laxative abuse can lead to a range of biochemical problems. Hypokalaemia is the most common electrolyte abnormality.
How do you feel when your calcium is high?
Stomach pain and digestive problems: Too much calcium can cause an upset stomach, abdominal pain, nausea, vomiting, and constipation. Bone pain and muscle weakness: Hypercalcemia can cause the bones to release too much calcium, leaving them deficient. This abnormal bone activity can lead to pain and muscle weakness.
What level of hypercalcemia is fatal?
Hypercalcemia is considered mild if the total serum calcium level is between 10.5 and 12 mg per dL (2.63 and 3 mmol per L). Levels higher than 14 mg per dL (3.5 mmol per L) can be life threatening.
How do you reverse hypercalcemia?
- Calcitonin (Miacalcin). This hormone from salmon controls calcium levels in the blood.
- Calcimimetics. This type of drug can help control overactive parathyroid glands.
- Bisphosphonates.
- Denosumab (Prolia, Xgeva).
- Prednisone.
- IV fluids and diuretics.
Can high calcium cause anger?
Depression, Fatigue, Anger Management, and Hyperparathyroidism. High blood calcium due to hyperparathyroidism is well known to cause “psychiatric” problems. It’s part of the classic “Bones, Stones, Groans, and Psychic Overtones” that was coined in the 1950’s.
When is hypercalcemia an emergency?
Severe hypercalcemia (Ca>4 mmol/l or 16 mg/dl) is often considered an emergency because of a potential risk of cardiac arrest or coma 1–5.
What is the first line treatment for hypercalcemia?
Intravenous bisphosphonates are the treatment of first choice for the initial management of hypercalcaemia, followed by continued oral, or repeated intravenous bisphosphonates to prevent relapse.
How long does it take for anorexia to cause osteoporosis?
The loss of bone mineral density (BMD) also takes place rapidly, often occurring within 6 months of disease onset [4] and persisting even after weight recovery [5].
Can osteoporosis from anorexia reversible?
Medication: There is no cure for osteoporosis. However, medications are available to prevent and treat the disease in postmenopausal women, men, and both women and men taking glucocorticoid medication.
Do all anorexics have osteoporosis?
Bone mineral density BMD in anorexic patients and healthy subjects has been compared by different authors. Anorexia patients always exhibit lower BMDs: osteoporosis is found in about 20%–30% of the patients,4–6 and osteopenia in 50%–90% of them.
What cancers are associated with hypercalcemia?
The most common cancers associated with hypercalcemia in the United States are breast, renal, lung, and squamous cell cancers and multiple myeloma [2]. Malignancy is usually evident clinically by the time it causes hypercalcemia, and patients with hypercalcemia of malignancy often have a poor prognosis.
