Purging can have several serious health consequences. Here are three key ones:

• Cardiovascular and fluid balance problems: Frequent purging can lead to dehydration and electrolyte imbalances (including low potassium and low chloride), which strain the heart and can cause irregular heart rhythms, fainting, or even heart attack in severe cases. It can also contribute to low blood pressure and reduced blood flow to organs.

• Dental and gastrointestinal complications: The stomach acid from purging can erode tooth enamel and irritate the esophagus, potentially causing dental problems and esophageal damage. Purging can also cause gastrointestinal issues such as esophageal tears or ulcers in some cases.

• Respiratory and renal risks: Aspiration of vomit during purging can lead to pneumonitis or pneumonia, and in some situations pneumothorax or pneumomediastinum. Repeated purging can also stress the kidneys, contributing to dehydration, electrolyte disturbances, and in severe or chronic cases, potential kidney injury.

If you or someone you know is struggling with purging or an eating disorder, consider seeking support from a healthcare professional or a eating disorder specialist. They can provide a thorough medical assessment and appropriate treatment options.
