Can bulimia cause hyponatremia?

Purging of all modalities can lead to hyponatremia due to loss of salt and water (aka: dehydration or volume depletion).

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).

What do anorexia nervosa and bulimia nervosa have in common?

Excessive exercise aimed at weight loss or at preventing weight gain is common in both anorexia nervosa and in bulimia.

Is hyperkalemia associated with anorexia nervosa?

In an adolescent with anorexia nervosa, recurrent hyperkalemia was caused by obsessive eating of up to 20 bananas per day. In another case, a patient with schizophrenia and psychogenic polydipsia was water-restricted but developed hyperkalemia because she replaced water with excessive consumption of orange juice.

Does bulimia cause 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.

Why is anorexia nervosa low in 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].

Is hypokalemia common in anorexia?

Hypokalemia is frequently found in patients with anorexia nervosa and sometimes leads to life-threatening conditions.

Which characteristic differentiates bulimia nervosa from anorexia nervosa?

People living with anorexia and bulimia use strategies to avoid gaining weight or reduce their weight. People with anorexia may avoid eating altogether, whereas people with bulimia have episodes of binge eating and then purge their body of food. Eating disorders often occur alongside other mental health conditions.

Which of the following appear to be the main cause of anorexia and bulimia?

Genetic Factors However, twin study research, which can isolate the role of genetics, has confirmed that approximately 40% to 60% of the risk for anorexia nervosa, bulimia nervosa, and binge eating disorder arises from genetic influence.

Which statement represents a similarity between anorexia and bulimia quizlet?

Which statement represents a similarity between anorexia and bulimia? They both most commonly affect women. Early intervention ______ the likelihood of recovery for a person with an eating disorder.

Does bulimia cause metabolic alkalosis?

Patients who purge by vomiting may present with metabolic alkalosis (elevated serum bicarbonate levels) due to volume contraction. However, patients who primarily abuse laxatives may present with metabolic acidosis (decreased serum bicarbonate levels) due to loss of alkaline fluid from the bowel.

Does anorexia cause metabolic alkalosis?

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. Metabolic alkalosis occurs in patients who vomit or abuse diuretics and acidosis in those misusing laxatives.

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.

Does bulimia cause magnesium deficiency?

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. Symptoms of mild hypomagnesemia include: Twitches, especially in the facial muscles.

Does bulimia cause hypoglycemia?

Bulimia with bingeing and vomiting can also cause hypoglycemia and alter glucose levels.

What happens to potassium in anorexia?

When calories are reintroduced to a starving body, potassium and other key electrolytes are absorbed into the new tissue cells, lowering the concentration of electrolytes in the blood. Cardiac complications of hypokalemia can include an irregular heartbeat, low blood pressure and cardiac arrest.

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.

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.

Can anorexia cause low glucose?

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).

What is the classic symptom of bulimia?

Living in fear of gaining weight. Repeated episodes of eating abnormally large amounts of food in one sitting. Feeling a loss of control during bingeing — like you can’t stop eating or can’t control what you eat. Forcing yourself to vomit or exercising too much to keep from gaining weight after bingeing.

Can someone have both anorexia and bulimia?

One-third of those with an intake diagnosis of anorexia nervosa experienced crossover to bulimia nervosa; while crossover from restricting-type anorexia nervosa to bulimia nervosa was unlikely, just over one-half of those with an intake diagnosis of binge eating/purging-type anorexia nervosa experienced crossover to …

Which characteristic is very common in individuals with anorexia nervosa but significantly?

People who suffer from anorexia nervosa tend to have high levels of harm avoidance, a personality trait characterized by worrying, pessimism, and shyness, and low levels of novelty seeking, which includes impulsivity and preferring new or novel things (Fassino et al., 2002).
