What are the consequences of long-term vomiting for weight loss

Long term vomiting and weight loss can lead to serious health problems, including electrolyte imbalances, gastrointestinal damage, tooth decay, malnutrition, and psychological disorders. Vomiting and weight loss can be achieved by artificially inducing vomiting to reduce calorie intake, but it may lead to consequences such as hypokalemia, gastroesophageal reflux, dental caries, vitamin deficiency, and eating disorders.

1. Electrolyte imbalance

Frequent vomiting can cause a significant loss of water and electrolytes in the body, especially key minerals such as potassium, sodium, and chlorine. Hypokalemia may cause muscle weakness, arrhythmia, and even cardiac arrest, which require urgent correction through intravenous fluid replacement. Long term electrolyte imbalance can also affect kidney function and increase the risk of urinary tract stones.

2. Gastrointestinal injury

Repeated reflux of gastric acid can burn the esophageal mucosa, leading to lesions such as esophagitis and Barrett's esophagus, and in severe cases, may induce esophageal cancer. Long term spasms and contractions in the stomach may cause tearing of the gastric mucosa, resulting in vomiting blood or black stools. Some patients may experience gastroparesis, characterized by postprandial bloating and worsening nausea.

3. Tooth Corrosion

Continuous contact of gastric acid with enamel can lead to tooth demineralization, manifested as tooth sensitivity, yellowing, or the appearance of pits. The inner side of the incisors is the earliest site of erosion, and in severe cases, root canal treatment or full crown restoration may be necessary. Reduced saliva secretion can also increase the probability of oral ulcers and dental caries.

4. Malnutrition

Long term inadequate nutrient absorption can lead to protein and energy malnutrition, resulting in dry skin, hair loss, and brittle nails. Lack of vitamin B1 may trigger Wernicke's encephalopathy, characterized by confusion and ataxia. Women may experience hormonal imbalances such as amenorrhea and osteoporosis.

5. Psychological disorders [SEP]: Vomiting behavior can easily evolve into neurotic bulimia, forming a vicious cycle of binge eating and vomiting. Patients often experience anxiety and depression, and some may have body image disorders. Even if their weight is low, they still insist on losing weight. Social avoidance and concealment behaviors may further deteriorate mental health.

It is recommended to control weight through a balanced diet and scientific exercise, with daily calorie intake not lower than basal metabolic requirements. It can increase the intake of vegetables, fruits, and high-quality protein that are rich in dietary fiber, and stabilize blood sugar by eating small meals frequently. If you have a tendency towards eating disorders, you should seek professional guidance from a psychologist and nutritionist in a timely manner, and avoid taking laxatives or diuretics on your own. Regular blood routine, electrolyte and bone density tests, early intervention can significantly reduce the risk of organ damage.
