Hypomagnesemia is an electrolyte disturbance caused when there is a low level of serum magnesium (less than 1.46 mg/dL) in the blood. Hypomagnesemia can be attributed to chronic disease, alcohol use disorder, gastrointestinal losses, renal losses, and other conditions.
What electrolyte imbalance does bulimia cause?
The typical electrolyte abnormalities associated with bulimia are hypokalemia and metabolic acidosis. Different purging methods result in different constellations of serum and urine electrolyte disturbances (see accompanying table).
Do bulimics have low potassium?
Low potassium level, or hypokalemia, is the most serious consequence of bulimia because it causes heart arrhythmias (irregular heartbeats), cardiomyopathy (weakening heart), muscle weakness that can border on paralysis, and tetany (involuntary muscle contractions)2.
What labs are elevated in bulimia?
Laboratory abnormalities become more common with decreasing weight and increasing severity of purging behaviors. The electrolyte levels are most likely to be affected. Hypokalemia, hypochloremia, hyperphosphatemia, and metabolic alkalosis are common, especially in lower-weight bulimics.
Does bulimia cause hyponatremia?
Generally, more chronic diarrhea results in a metabolic alkalosis. Hyponatremia can also be present with these 3 purging behaviors. The hyponatremia encountered is most often of the hypovolemic type due to chronic fluid depletion as a result of the purging behaviors.
Why does hypokalemia occur in bulimia?
Rates of renal potassium secretion are further increased in the presence of an elevated aldosterone level secondary to volume contraction, causing worsening hypokalemia.
Does bulimia cause low magnesium?
Frequent purging can cause malnutrition, especially low magnesium. A magnesium deficiency can also cause calcium and potassium deficiencies, as magnesium helps absorb and transport these electrolytes through the body.
How does vomiting affect electrolytes?
Electrolyte and water loss Excessive vomiting, especially over a prolonged period of time, leads to excess loss of water and electrolytes from the body. Electrolytes such as sodium, potassium, calcium, magnesium, bicarbonates and chloride ions are essential for normal bodily functions.
What deficiencies does bulimia cause?
Bulimia can eventually lead to physical problems associated with not getting the right nutrients, vomiting a lot, or overusing laxatives. Possible complications include: feeling tired and weak. dental problems – stomach acid from persistent vomiting can damage tooth enamel.
Which of the following electrolyte abnormalities is consistent with binge purging behavior?
Metabolic acidosis and alkalosis Metabolic alkalosis or a high serum bicarbonate (often denoted as carbon dioxide on lab reports) level is one of the most common electrolyte abnormalities seen in eating disorders associated with purging via vomiting.
Does bulimia show in blood tests?
There aren’t any laboratory tests to specifically diagnose bulimia. Your healthcare provider may order tests to see how bulimia has affected your health.
What tests are used to diagnose bulimia?
- Talk to you about your eating habits, weight-loss methods and physical symptoms.
- Do a physical exam.
- Request blood and urine tests.
- Request a test that can identify problems with your heart (electrocardiogram)
- Perform a psychological evaluation, including a discussion of your attitude toward your body and weight.
Why is amylase increased in bulimia?
Conclusion. These findings provide evidence to suggest that it is recurrent binge eating involving large amounts of food, rather than self-induced vomiting, which contributes to elevated serum amylase values in BN.
What ions are lost in vomiting?
The vomiting of gastric or intestinal contents most commonly involves the loss of fluid that contains chloride, potassium, sodium, and bicarbonate. The sequelae of these losses include dehydration along with hyponatremia, hypochloremia, and hypokalemia.
Does bulimia cause hypoglycemia?
Bulimia with bingeing and vomiting can also cause hypoglycemia and alter glucose levels.
How can bulimia cause dehydration?
Circulatory system. Frequent purging can cause dehydration. This leads to weak muscles and extreme fatigue. It can also throw your electrolytes out of balance and put strain on your heart.
What eating disorders cause low sodium?
Anorexia nervosa (AN) is a psychiatric disorder characterized by restrictive eating, low body weight, and severe bone loss. Recent data show a deleterious relationship between low circulating sodium levels and bone mass, and relative or absolute hyponatremia is a known complication of AN.
How does anorexia affect electrolytes?
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).
What vitamins should bulimics take?
B Vitamins These vitamins are also important in preventing depression. The B vitamins that are most important to appetite control include vitamin B6, vitamin B12, inositol, and folate. They can be taken as individual supplements or, in many cases, taken together in the form of a B complex.
What causes low potassium and magnesium?
Low potassium and magnesium levels can be caused by diuretics and some medications, as well as excessive alcohol use, intestinal ailments and a variety of other health conditions.
Does vomiting cause hypokalemia?
Gastrointestinal losses, from diarrhea, vomiting, or nasogastric suctioning, also are common causes of hypokalemia. Vomiting leads to hypokalemia via a complex pathogenesis. Gastric fluid itself contains little potassium, approximately 10 mEq/L.
Does vomiting cause hyponatremia?
Hyponatremia might be the result of excessive vomiting by virtue of both fluids and electrolytes loss, as well as in association with metabolic alkalosis.
Does vomiting cause hypernatremia?
The main cause of hypernatremia usually involves dehydration due to an impaired thirst mechanism or limited access to water, according to the Merck Manual. The disorder can also result from diarrhea or vomiting, taking diuretics or having a high fever.
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.
Are bulimics dehydrated?
Effects of bulimia When you are living with bulimia, you are putting your body—and even your life—at risk. The most dangerous side effect of bulimia is dehydration due to purging. Vomiting, laxatives, and diuretics can cause electrolyte imbalances in the body, most commonly in the form of low potassium levels.
