Our study found that hypokalemia in patients with anorexia nervosa during refeeding is associated with a lower body mass index and hypoalbuminemia (low levels of serum albumin), in addition to bingeโpurge behavior.

Is bradycardia associated with anorexia?
Bradycardia is a Severe Anorexia Complication Bradycardia (heart rate less than 60 beats per minute) and hypotension (blood pressure less than 90/50) are among the most common physical findings in anorexia, with bradycardia seen in up to 95 percent of patients.
Does anorexia cause bradycardia or tachycardia?
Bradycardia is a characteristic feature of anorexia nervosa particularly with significant weight loss. When anorexia nervosa patients present with nonspecific symptoms, resting tachycardia should prompt a search for potentially life-threatening conditions.
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.
Which symptom is a primary characteristic of anorexia nervosa?
The main sign is significant weight loss or low body weight. In atypical anorexia nervosa, the person may still have a moderate weight despite substantial weight loss. A lack of nutrients may lead to other physical signs and symptoms, including: severe loss of muscle mass.
What are the reasons for bradycardia?
- Heart tissue damage related to aging.
- Damage to heart tissues from heart disease or heart attack.
- A heart condition present at birth (congenital heart defect)
- Inflammation of heart tissue (myocarditis)
- A complication of heart surgery.
- An underactive thyroid gland (hypothyroidism)
Can starvation cause bradycardia?
Bradycardia is observed in up to 95 percent of patients with anorexia nervosa (Mehler & Brown, 2015) as nearly all the body’s vital organs and systems are adversely affected by continued starvation, purging and overexercising.
What are the symptoms of bradycardia?
- Fatigue or feeling weak.
- Dizziness or lightheadedness.
- Confusion.
- Fainting (or near-fainting) spells.
- Shortness of breath.
- Difficulty when exercising.
- Cardiac arrest (in extreme cases)
Does anorexia cause high heart rate?
While low heart rate is an adapted response to prolonged starvation and negative energy balance, those with AN can have episodes of high heart rate as well.
Why does malnutrition cause bradycardia?
Malnutrition causes cellular changes within cardiac muscle, leading to structural, functional or electrocardiological complications. Commonly, cardiac rhythm disturbances occur; the majority develop sinus bradycardia as an adaptation to the hypometabolic state.
What happens to your heart when you have anorexia?
The heart specifically becomes smaller and weaker, making it more difficult to circulate blood at a healthy rate. Other affects of anorexia on the heart include: Abnormally slow heart rate (bradycardia) when weak heart muscles cannot pump at a healthy rate. Low blood pressure as a result of slow heart rate.
What other disorders might occur with anorexia nervosa?
- Depression.
- Obsessive-Compulsive Disorder.
- Alcoholism, Addiction, and Substance Abuse.
- Post-Traumatic Stress Disorder.
- Anxiety.
- The Importance of Integrated Care.
- What Are Level of Care Options for Dual Diagnosis Treatment.
Can malnutrition cause low potassium?
Mortality rates increase if potassium levels are below 2.5 mEq/l (severe hypokalaemia) [4]. Poor intake and poor muscle bulk in malnourished children results in the fall of total serum potassium levels (by as much as 25%).
What are the symptoms of hypokalemia?
- Constipation.
- Heart palpitations.
- Extreme tiredness (fatigue).
- Muscle weakness and spasms.
- Tingling and numbness.
What are the three essential diagnostic features of anorexia nervosa?
Anorexia nervosa is an eating disorder characterized by weight loss (or lack of appropriate weight gain in growing children); difficulties maintaining an appropriate body weight for height, age, and stature; and, in many individuals, distorted body image.
What is the main difference between anorexia and anorexia nervosa?
“Anorexia” describes a simple inability or aversion to eating, whether caused by a medical problem or a mental health issue. “Anorexia nervosa,” however, is the name for the clinical eating disorder, the main symptom of which is self-starvation.
Which of the following is characteristic of a person with anorexia?
Anorexia nervosa is characterized by emaciation, a relentless pursuit of thinness and unwillingness to maintain a normal or healthy weight, a distortion of body image and intense fear of gaining weight, a lack of menstruation among girls and women, and extremely disturbed eating behavior.
Which of the following symptoms confirm anorexia nervosa?
- Extreme weight loss or not making expected developmental weight gains.
- Thin appearance.
- Abnormal blood counts.
- Fatigue.
- Insomnia.
- Dizziness or fainting.
- Bluish discoloration of the fingers.
- Hair that thins, breaks or falls out.
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.
Which long term health effect is highly associated with a diagnosis of anorexia nervosa?
One of the top long-term health risks of anorexia has to do with our bones. Nearly 90 percent of women with anorexia experience a condition known as Osteopenia, which translates to a loss of bone calcium.
What are the two types of bradycardia?
- First degree heart block.
- Second degree heart block.
- Third degree heart block.
What heart rate is bradycardia?
Bradycardia is a condition where your heart beats fewer than 60 times per minute, which is unusually slow.
Does anxiety cause bradycardia?
Typically, anxiety does not slow the heart rate. But it can cause people to pulse check too often, or feel their heartbeat is slower when it is not.
Can losing weight cause bradycardia?
Although the incidence of adverse outcomes associated with bariatric surgery has reduced, the physiological compensatory changes occurring after weight loss can lead to some unavoidable outcomes. One such condition is sinus bradycardia.
What is the drug of choice for bradycardia?
The drug of choice is usually atropine 0.5โ1.0 mg given intravenously at intervals of 3 to 5 minutes, up to a dose of 0.04 mg/kg. Other emergency drugs that may be given include adrenaline (epinephrine) and dopamine.
