Low blood sodium is common in older adults, especially those who are hospitalized or living in long-term care facilities. Signs and symptoms of hyponatremia can include altered personality, lethargy and confusion. Severe hyponatremia can cause seizures, coma and even death.
Why does anorexia cause hyponatremia?
Hyponatremia can also be seen in severe restrictive eating disorders due to decreased ability of the kidney to excrete free water as a result of low nutritional intake. Without enough food or solutes, even a fairly normal amount of water intake can lead to hyponatremia if the body retains too much of it.
Can anorexia cause low sodium levels?
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 are 2 major complications from anorexia nervosa?
- Heart problems, such as mitral valve prolapse, abnormal heart rhythms or heart failure.
- Bone loss (osteoporosis), increasing the risk of fractures.
- Loss of muscle.
- In females, absence of a period.
- In males, decreased testosterone.
- Gastrointestinal problems, such as constipation, bloating or nausea.
Does anorexia nervosa lead to 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. Metabolic alkalosis occurs in patients who vomit or abuse diuretics and acidosis in those misusing laxatives.
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.
Why do anorexics have low potassium?
Inpatients with anorexia nervosa presumably have a higher risk of developing hypokalemia because they suffer from severe malnutrition and are refed , in which the insulin surge resulting from glycemia during the refeeding process causes a substantial intracellular uptake of potassium and phosphorus .
What other disorders might occur with anorexia nervosa?
- Substance abuse/alcohol.
- Borderline personality disorder (BPD)
- Obsessive-compulsive disorder (OCD)
What is the most common medical complication of anorexia?
Cardiac. Bradycardia (pulse
What are three long-term effects of anorexia?
- Bone weakening (osteoporosis).
- Thyroid problems.
- Lack of vitamins and minerals.
- Low potassium levels in the blood.
- Decrease in white blood cells.
- Amenorrhea (absence of menstruation in females).
Which is the most serious health risk resulting from anorexia nervosa?
Anorexia nervosa is a serious medical condition that can affect every organ system of the body. The most serious health risk of anorexia is increased mortality.
Why do electrolytes drop in refeeding syndrome?
When you begin refeeding, your cells demand these electrolytes to metabolize the food. This causes a severe shift in your body chemistry. The electrolytes you have move rapidly from your blood into your cells. But because you don’t have enough, this shift leaves low levels of them in your blood.
What electrolytes are affected in refeeding syndrome?
Refeeding syndrome involves metabolic abnormalities when a malnourished person begins feeding, after a period of starvation or limited intake. In a starved body, there is a breakdown of fat and muscle, which leads to losses in some electrolytes like potassium, magnesium, and phosphate.
What is refeeding syndrome in anorexia?
Refeeding syndrome (RS) is one of the serious complications during treatment of anorexia nervosa. It includes hormonal and metabolic changes that occur during the process of refeeding in chronically malnourished patient when nutrition is introduced in an excessive and improper amount.
What is the most common cause of hyponatremia?
Drinking too much water. Drinking excessive amounts of water can cause low sodium by overwhelming the kidneys’ ability to excrete water. Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can also dilute the sodium content of your blood.
Which organ is most affected by hyponatremia?
Hyponatremia occurs when your blood sodium level goes below 135 mEq/L. When the sodium level in your blood is too low, extra water goes into your cells and makes them swell. This swelling can be dangerous especially in the brain, since the brain cannot expand past the skull.
Which is a characteristic of an individual who suffers from anorexia nervosa?
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).
Which hormone levels is increased in anorexia nervosa?
Anorexia nervosa is a state of acquired growth hormone (GH) resistance, characterized by increased GH secretion and decreased systemic insulin-like growth factor 1 (IGF1) levels.
What happens when your body is low on electrolytes?
A level under three can cause muscle weakness, spasms, cramps, paralysis and respiratory problems. If it continues, kidney problems may occur.
Can malnutrition cause hypokalemia?
Several factors may trigger the hypokalemia in PD patients, such as preexisting malnutrition and the low protein and potassium food intake. OBJECTIVES: To verify the prevalence of hypokalemia and its association with mortality, nutrition status, clinical, laboratory and electrocardiographic variables in PD patients.
What damage to the body is a result of anorexia?
Nearly 90 percent of women with anorexia experience a condition known as Osteopenia, which translates to a loss of bone calcium. Up to 40 percent of the people that suffer from anorexia may also face Osteoporosis, which means an advanced loss of bone density.
What disorders are often seen along with eating disorders?
There are three main types of eating disorders: anorexia nervosa, bulimia nervosa and binge eating disorder. Eating disorders often co-occur with other psychiatric disorders most commonly mood and anxiety disorders, obsessive compulsive disorder and alcohol and drug abuse problems.
Which disorders are often comorbid with eating disorders?
- bipolar disorder.
- panic and anxiety disorders.
- post-traumatic stress disorder(PTSD)
- obsessive compulsive disorder (OCD)
- obsessive compulsive personality disorder (which is different from OCD)
- borderline personality disorder.
- sleep disorders.
How do you feel when sodium is low?
Sodium is an electrolyte that plays an essential role in regulating levels of water and other substances in the body. When sodium levels in the blood become too low, it leads to hyponatremia, causing symptoms that include lethargy, confusion, and fatigue.
What is a critical low 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.
