Dental alterations, with a tendency to corrosion of the dental enamel and the presence of caries. This is especially evident in patients who purge through self-induced vomiting.

Gastrointestinal disorders: flatulence, swelling, abdominal pain and constipation (except if laxatives are used, which can cause diarrhoea that alters the electrolyte balance).

Cardiovascular alterations: low blood pressure (hypotension), drop in heart rate, alterations in heart rhythm, etc.

Kidney alterations: indicative of a malfunction. Low potassium levels, high levels of nitrogen-derived compounds, and elevated serum creatinine levels may be found.

Hemogram: low levels of red blood cells (anemia) and white blood cells.

Biochemical levels: low glucose levels, increased triglycerides, transaminases and the general proteinogram, as well as cholesterol (hypercholesterolemia). If the patient, in addition, usually uses purging agents, enemas, or self-induced vomiting, there are other specific parameters altered.
