What is a common metabolic complication associated with bulimia?

The typical electrolyte abnormalities associated with bulimia are hypokalemia and metabolic acidosis.

Can bulimia cause electrolyte imbalance?

Almost half of all people with bulimia have electrolyte imbalances. [2] A bulimia electrolyte imbalance can cause dizziness, confusion, and swelling in your hands and feet. If left untreated, these issues can cause life-threatening complications, including heart damage.

Can anorexia cause metabolic alkalosis?

Self-induced vomiting is a common feature of the eating disorders anorexia nervosa and bulimia. Because these individuals are losing HCl from stomach secretions, it is not uncommon for them to develop a metabolic alkalosis.

Does bulimia affect metabolic rate?

Resting metabolic rate, adjusted for differences in lean body mass, was significantly lower in bulimics (mean +/- SE, 4201 +/- 126 kJ/d) than healthy volunteers (4694 +/- 172 kJ/d).

What labs should be checked for bulimia?

  • Comprehensive blood chemistry panel: This is important in detecting possible occult metabolic complications of bulimia.
  • Complete blood cell count: This is used to exclude anemia or other occult hematologic abnormalities.
  • Urinalysis: Urine specific gravity may reflect the state of hydration.

What is the most significant feature of bulimia?

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.

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.

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.

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.

When does metabolic alkalosis occur?

Metabolic alkalosis occurs when digestive issues disrupt the blood’s acid-base balance. It can also be due to conditions affecting the liver, kidneys or heart. Metabolic alkalosis is usually not life-threatening. It does not have lingering effects on your health once it is treated.

How does purging affect the metabolism?

Metabolic Abnormalities Caused by Purging Can Be Life Threatening. Purging behaviors, causing abnormalities seen with sodium, potassium, chloride, bicarbonate, most commonly disrupts electrolyte levels and overall pH levels.

Why is bicarbonate high in metabolic alkalosis?

Metabolic alkalosis, a disorder that elevates the serum bicarbonate, can result from several mechanisms: intracellular shift of hydrogen ions; gastrointestinal loss of hydrogen ions; excessive renal hydrogen ion loss; administration and retention of bicarbonate ions; or volume contraction around a constant amount of …

Does bulimia cause weight loss?

(1) People with bulimia sometimes make themselves vomit to eliminate the calories they consume. The bingeing and purging cycle isn’t even an effective way to lose weight. Indeed, many people with bulimia actually gain weight over time. Your body starts absorbing calories from the moment you put food in your mouth.

How can I boost up my metabolism?

  1. Exercise more. Add interval training to your cardio routine and burn more calories in less time.
  2. Weight train.
  3. Don’t skip meals, especially breakfast.
  4. Eat fat-burning foods.
  5. Get a good night’s sleep every night.

Does bulimia cause acidosis or 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.

Can blood Work detect bulimia?

There aren’t any laboratory tests to specifically diagnose bulimia. Your healthcare provider may order tests to see how bulimia has affected your health. These tests include: Blood test.

What are the three essential diagnostic features of bulimia nervosa?

The diagnostic criteria for bulimia in the DSM are: 1) recurrent episodes of binge eating with a sense of lack of control occurring at least twice per week for at least three months, 2) recurrent, inappropriate compensatory behavior, such as vomiting, in order to prevent weight gain 3) and self-evaluation that is …

When is bulimia considered severe?

Severe bulimia nervosa (BN) is defined as 8–13 binge/purge episodes per week), and extreme bulimia nervosa involves 14 or more binge/purge episodes per week. Unhealthy preoccupation with weight loss, body weight and shape; significant body image distortions.

Why is anorexia harder than bulimia?

While more common than anorexia, bulimia nervosa may be more difficult for primary care physicians, school officials, parents and other loved ones to detect because patients are often of normal weight and may not disclose their abnormal eating behaviors.

What is the typical profile of a person with bulimia nervosa?

The typical profile of a person with bulimia nervosa is an adolescent to young adult female who is impulsive, perfectionistic, hard-working, introverted, resistant to change and self-critical. They also tend to have low self-esteem based on body image distortion.

Can bulimia cause hyperkalemia?

Self-induced vomiting is the most common method of purging in BN. Patients with self-induced vomiting or diuretic abuse, or both, have been shown to present with hypokalemia, hypochloremia, and a metabolic alkalosis. The severity of the electrolyte abnormalities worsens with the frequency of vomiting.

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 supplements should bulimics take?

People with bulimia may not be getting the nutrients their bodies need. Your health care provider may prescribe potassium or iron supplements, or other supplements to make up for any loss. Preliminary studies suggest a drug called zonisamide may also be effective in treating bulimia.

Can bulimics get refeeding syndrome?

Although bulimia does not usually result in unhealthy and significant weight loss, refeeding is still sometimes a necessary part of patient recovery.
