Vomiting or nasogastric (NG) suction generates metabolic alkalosis by the loss of gastric secretions, which are rich in hydrochloric acid (HCl). Whenever a hydrogen ion is excreted, a bicarbonate ion is gained in the extracellular space.

Does bulimia cause acidosis or alkalosis?
The typical electrolyte abnormalities associated with bulimia are hypokalemia and metabolic acidosis.
What is a common metabolic complication associated with bulimia?
Bulimia nervosa can lead to a variety of general medical complications, including metabolic alkalosis, dehydration, constipation, and cardiac arrhythmias.
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).
Why 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.
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 are 3 effects of bulimia?
Bulimia can permanently damage your stomach and intestines, causing other problems like constipation, diarrhea, and irritable bowel syndrome. Hormonal problems. Reproductive issues, including irregular periods, missed periods, and fertility problems are common side effects when you have bulimia. Diabetes connection.
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 triggers metabolic alkalosis?
What causes metabolic alkalosis? Metabolic alkalosis may be caused by consuming excessive amount of certain medications or supplements such as: Antacids, which often contain the chemical sodium bicarbonate. Baking soda. Diuretics or water pills.
What are three causes of metabolic alkalosis?
- Loss of stomach acids. This is the most common cause of metabolic alkalosis.
- Excess of antacids.
- Diuretics.
- Potassium deficiency (hypokalemia).
- Reduced volume of blood in the arteries (EABV).
- Heart, kidney, or liver failure.
- Genetic causes.
What disease causes metabolic alkalosis?
Thus, metabolic alkalosis can only persist if the ability to excrete excess bicarbonate in the urine is impaired due to one of the following causes: hypovolemia; reduced effective arterial blood volume (due, for example, to heart failure or cirrhosis); chloride depletion; hypokalemia; reduced glomerular filtration rate …
Can you have bulimia and still be overweight?
People with bulimia have a fear of gaining weight; however, that does not mean all people with bulimia are underweight. Some people with bulimia are overweight or obese and may attempt to use purging to manage their weight or to prevent additional weight gain.
Does bulimia cause trauma?
Specifically, trauma is more common in bulimia nervosa (BN) compared to non-BN patients (Smolak & Murnen, 2002; Striegel-Moore, Dohm, Pike, Wilfley & Fairburn, 2002).
Do people with bulimia stay the same weight?
Purging does NOT prevent weight gain Purging isn’t effective at getting rid of calories, which is why most people suffering with bulimia end up gaining weight over time. Vomiting immediately after eating won’t eliminate more than 50% of the calories consumed— usually much less.
How does vomiting cause metabolic acidosis?
Vomiting causes changes in acid base balance due to loss of chloride ions from the stomach, which can lead to an increase of HCO3 in the extracellular fluid. Our patient had her first episode of CVS when she was 3 years old and each episode of CVS is associated with metabolic acidosis.
Which chemical is responsible for bulimia?
Research has shown that bulimia is associated with lower levels of both dopamine and certain of its receptors, and that binge eating is significantly associated with dopamine release in certain parts of the brain (Broft et al., 2012).
What are 5 physical effects of bulimia?
- anemia.
- low blood pressure and irregular heart rate.
- dry skin.
- ulcers.
- decreased electrolyte levels and dehydration.
- esophageal ruptures from excessive vomiting.
- gastrointestinal problems.
- irregular periods.
How do you correct metabolic alkalosis?
Metabolic alkalosis is corrected with the aldosterone antagonist spironolactone or with other potassium-sparing diuretics (eg, amiloride, triamterene). If the cause of primary hyperaldosteronism is an adrenal adenoma or carcinoma, surgical removal of the tumor should correct the alkalosis.
What happens during metabolic alkalosis?
Normal human physiological pH is 7.35 to 7.45. A decrease in pH below this range is acidosis, an increase over this range is alkalosis. Metabolic alkalosis is defined as a disease state where the body’s pH is elevated to greater than 7.45 secondary to some metabolic process.
What are the signs and symptoms of metabolic alkalosis?
- Confusion (can progress to stupor or coma)
- Hand tremor.
- Lightheadedness.
- Muscle twitching.
- Nausea, vomiting.
- Numbness or tingling in the face, hands, or feet.
- Prolonged muscle spasms (tetany)
How many years does bulimia take off your life?
² Roughly 50% of women will recover from bulimia within ten years of their diagnosis, but an estimated 30% of these women will experience a relapse of the disorder. ³ These behaviors can wreak havoc on the body both in the short-term and the long-term.
What are two long term effects of bulimia?
- Sever dehydration.
- Tooth decay & cavities.
- Irregular periods.
- Constipation.
- Boating.
- Acid reflux.
- Stomach ulcers.
- Kidney issues.
What is the survival rate of bulimia?
Up to now, only 50% all people with this devastating disease report being cured. One in 200 American women suffers from anorexia. Two to three in 100 American women suffers from bulimia.
Can you reverse damage from bulimia?
If treated swiftly and correctly, individuals are able to experience recovery and healing, along with the reversal of most, but not all, of the physical consequences. However, without professional treatment, bulimia nervosa may be life-threatening.
