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).

Can bulimia cause low sodium levels?
Up to 49% of individuals with severe symptomatology of bulimia have imbalances such as sodium and potassium [1]. Those who purge are also at risk for hypokalemia, metabolic alkalosis, and hypochloremia.
Can anorexia cause hyponatremia?
Hyponatraemia is a common problem in anorexia nervosa but it is relatively under-recognized. The most common cause is excessive water ingestion, leading to dilutional hyponatraemia. In some cases this is deliberate and is done in order to increase weight prior to weighing (‘water loading’).
What eating disorder is caused by low sodium levels?
Purpose. 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.
What is normal sodium level?
A normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L). Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L. Many possible conditions and lifestyle factors can lead to hyponatremia, including: Certain medications.
Does bulimia cause dehydration?
Effects of bulimia 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.
Does bulimia cause hypernatremia?
Sodium. Hypernatremia is high sodium levels in ratio to water in the blood because of dehydration, which can be caused by purging through self-induced vomiting and/or abuse of diuretics and/or laxatives.
Why is Bicarb increased in bulimia?
This is one of the most common electrolyte abnormalities associated with purging. Vomiting, laxative and diuretic abuse can cause a rise in bicarbonate because of dehydration.
What ions are lost in vomiting?
Electrolytes and acid-base disorders 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.
Can starvation cause hyponatremia?
Malnutrition can lead to hyponatremia and prerenal AKI. However, long-term malnutrition may also affect the tubular function of the kidney. Severe hyponatremia, other electrolyte disturbances, and protein and vitamin deficiency can be factors that interact in this pathogenesis.
Which eating disorder is most associated with electrolyte imbalance?
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.
Can low sodium levels cause depression?
Anxiety and depression are comorbid conditions linked to electrolyte deficiencies. Because we evolved to crave sodium, sodium deficiency may cause depressive symptoms.
What is a critical sodium level?
Any value below 135 mEq/L is considered to be a low sodium level, a condition medically referred to as hyponatremia. As sodium levels drop to 125 mEq/L, the situation becomes more serious. And when the sodium level drops to 115 mEq/L or below, the situation is critical and requires immediate treatment.
What does a sodium level of 115 mean?
Severe hyponatremia (serum/plasma sodium <115 mmol/L), particularly of rapid onset, is associated with marked confusion, seizures and coma; without emergent treatment, severe hyponatremia can be fatal.
What is the most common cause of low sodium?
Kidney problems So, the most common reason for low sodium is a kidney problem. When the kidneys are not functioning normally, which can be seen in chronic kidney disease or even temporary dehydration, the body holds too much water. And the proportion of sodium compared to water in the body lowers the sodium level.
Is sodium level of 128 too low?
How low is too low? Your blood sodium level is normal if it’s 135 to 145 milliequivalents per liter (mEq/L). If it’s below 135 mEq/L, it’s hyponatremia.
What does a sodium level of 139 mean?
Normal sodium levels are usually between 136 and 145 millimoles per liter (mmol/L). Blood sodium levels below 136 mmol/L may mean you have low blood sodium (hyponatremia). Blood sodium levels greater than 145 mmol/L may mean you have blood sodium levels that are too high (hypernatremia).
What does it mean when sodium is low?
Low blood sodium (hyponatremia) occurs when you have an abnormally low amount of sodium in your blood or when you have too much water in your blood. Low blood sodium is common in older adults, especially those who are hospitalized or living in long-term care facilities.
What are 5 physical effects of bulimia?
- anemia.
- low blood pressure and irregular heart rate.
- dry skin.
- ulcers.
- decreased electrolyte levels and dehydration.
- esophageal ruptures from excessive vomiting.
- gastrointestinal problems.
- irregular periods.
Do anorexics get dehydrated?
Folks living with eating disorders, particularly Anorexia Nervosa and Bulimia Nervosa, are at a higher risk of dehydration. Severe dehydration can be very dangerous and must be taken seriously.
Does water help bulimia?
Drinking excess amounts of water First, water is an easy way to curb hunger pains and not intake calories while skipping meals. Second, constant purging can quickly lead to dehydration, and their body will require a lot of water to keep running properly.
What are 3 complications of bulimia?
- Negative self-esteem and problems with relationships and social functioning.
- Dehydration, which can lead to major medical problems, such as kidney failure.
- Heart problems, such as an irregular heartbeat or heart failure.
- Severe tooth decay and gum disease.
- Absent or irregular periods in females.
Does bulimia cause electrolyte imbalance?
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).
What is the most significant feature of bulimia?
Bulimia is an eating disorder. It is characterized by uncontrolled episodes of overeating, called bingeing. This is followed by purging with methods such as vomiting or misuse of laxatives. Bingeing is eating much larger amounts of food than you would normally eat in a short period of time, usually less than 2 hours.
What labs are abnormal with bulimia?
LABORATORY ABNORMALITIES The electrolyte levels are most likely to be affected. Hypokalemia, hypochloremia, hyperphosphatemia, and metabolic alkalosis are common, especially in lower-weight bulimics.
