Vomiting leads to hypokalemia via a complex pathogenesis. Gastric fluid itself contains little potassium, approximately 10 mEq/L. However, vomiting produces volume depletion and metabolic alkalosis, which are accompanied by increased renal potassium excretion.

Does bulimia affect potassium?
Can bulimia cause low potassium? Yes. This condition is also known as hypokalemia, and it’s a common issue in people who vomit regularly as part of bulimia.
Why is potassium low in bulimia?
First, and most obvious, there is loss of potassium in the purged gastric contents, excessive stool from laxative abuse, or in the urine through diuretic abuse. Second, chronic purging results in intravascular fluid depletion.
What labs are elevated in bulimia?
Laboratory abnormalities become more common with decreasing weight and increasing severity of purging behaviors. The electrolyte levels are most likely to be affected. Hypokalemia, hypochloremia, hyperphosphatemia, and metabolic alkalosis are common, especially in lower-weight bulimics.
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.
What are 3 complications of bulimia?
Possible complications include: 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.
Does vomiting make your potassium low?
Vomiting, diarrhea or both also can result in excessive potassium loss from the digestive tract. Occasionally, low potassium is caused by not getting enough potassium in your diet. Causes of potassium loss include: Alcohol use (excessive)
Why do you lose potassium with vomiting?
Although vomiting can cause fluid loss directly from gastrointestinal tract, potassium depletion in this setting is primarily due to increased urinary losses [2] from the fact that concentration of potassium in gastric secretions is only 5 to 10 mEq/L.
How long does it take to recover from low potassium?
Usually, 60–80 mmol of supplements per day for a few days to weeks is sufficient for treating mild to moderate hypokalemia. That said, always follow the recommendations of your healthcare professional ( 1 , 19 ). In severe hypokalemia cases, intravenous (IV) treatment may be recommended.
What are 2 warning signs of bulimia?
- Episodes of binge eating.
- Self-induced vomiting.
- Smelling like vomit.
- Misuse of laxatives and diuretics.
- Complaining about body image.
- Expressing guilt or shame about eating.
- Depression.
- Irritability.
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 3 characteristics of bulimia?
- Usually a normal or above average body weight.
- Recurrent episodes of binge eating and fear of not being able to stop eating.
- Self-induced vomiting (usually secretive)
- Excessive exercise.
- Excessive fasting.
- Peculiar eating habits or rituals.
What vitamins should bulimics take?
B Vitamins These vitamins are also important in preventing depression. The B vitamins that are most important to appetite control include vitamin B6, vitamin B12, inositol, and folate. They can be taken as individual supplements or, in many cases, taken together in the form of a B complex.
What are 8 health problems that come as a result of bulimia?
Other long-term consequences of bulimia include damage to the kidneys, increased risk of kidney stones and kidney failure, diabetes, high cholesterol, hormonal imbalances, fertility problems, chronic dehydration, chronic fatigue, and electrolyte imbalances.
What disorder is commonly comorbid with bulimia?
Major depression is the most common comorbidity, followed by anxiety disorders, including generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, social phobia, and posttraumatic stress disorder in nearly 60% of bulimia nervosa patients.
What is the most serious medical consequence of bulimia?
Those with bulimia are at heightened risk for dehydration because water volume can drop so quickly during a purging episode. If too much water is purged from the body, it can result in serious medical complications including hypovolemic (low blood volume) shock, seizures and kidney or heart failure.
What is the most serious consequence of bulimia?
Health Consequences of Bulimia Nervosa Electrolyte imbalances that can lead to irregular heartbeats and possibly heart failure and death. Electrolyte imbalance is caused by dehydration and loss of potassium, sodium and chloride from the body as a result of purging behaviors.
What is the most insignificant characteristic of a person with bulimia?
What is the most insignificant characteristic of a person with bulimia? The person is close to her ideal body weight. Bulimia nervosa is more prevalent than anorexia nervosa in both women and men. What is not a risk of being underweight?
What are the 10 signs of low potassium?
- weakness.
- feeling tired.
- muscle cramps.
- confusion.
- constipation.
- an abnormal heart rhythm (arrhythmia) – skipped heartbeats or an irregular heartbeat.
- tingling or numbness.
- increased urination.
What electrolytes are depleted with 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.
What are 3 causes of hypokalemia?
- Cushing’s syndrome.
- Gitelman syndrome.
- Liddle syndrome.
- Bartter syndrome.
- Fanconi syndrome.
How quickly do potassium levels change?
High potassium usually develops slowly over many weeks or months, and is most often mild. It can recur. For most people, the level of potassium in your blood should be between 3.5 and 5.0, depending on the laboratory that is used.
Can vomiting cause hyperkalemia?
Upper gastrointestinal loses –voluminous vomiting causes a rise in bicarbonate concentration due to large losses of gastric acid. This, in conjunction with hypovolemia- induced aldosterone secretion, causes increased potassium secretion and large urinary potassium losses.
What causes potassium levels to drop drastically?
Low blood potassium typically occurs because of an excessive loss of potassium in your digestive tract. This may be due to frequent vomiting, diarrhea or laxative use. Other causes of hypokalemia include: Eating disorders, such as bulimia nervosa.
What happens if low potassium is not treated?
Very low levels of potassium in the body can lead to irregular heart rhythms, including sinus bradycardia, ventricular tachycardia, and ventricular fibrillation. If a person does not receive treatment, these conditions can be life-threatening. Doctors can detect irregular heart rhythms using an electrocardiogram (EKG).
