Bulimia nervosa can cause swollen cheeks due to a specific behavior associated with the disorder known as self-induced vomiting. When individuals with bulimia binge eat, consuming large quantities of food in a short period, they may feel an intense need to get rid of the calories and avoid weight gain.
To accomplish this, they induce vomiting, which involves the forceful expulsion of stomach contents through the mouth. Frequent vomiting can lead to several physical effects, including swollen cheeks. Here's why:
Irritation and inflammation: The stomach's acidic contents, which are designed to break down food, are not meant to come into contact with the sensitive tissues in the mouth and throat. The frequent exposure to stomach acid during vomiting irritates and inflames the mucous membranes of the mouth, throat, and cheeks.
Salivary glands: Frequent vomiting can also cause swelling of the salivary glands, which are responsible for producing saliva to aid in the digestion of food. The glands become enlarged due to the repeated stimulation caused by vomiting, leading to swollen cheeks.
Damage to teeth and mouth: The acidic nature of stomach contents can erode tooth enamel and cause other dental problems, such as cavities and tooth sensitivity. The enamel erosion and oral health issues can contribute to swollen cheeks and a puffy appearance.
Electrolyte imbalances: Frequent purging through vomiting can lead to imbalances in the body's electrolytes, such as potassium, sodium, and chloride. These imbalances can cause fluid retention, leading to facial swelling.
It's important to note that swollen cheeks are just one of the many physical and psychological consequences of bulimia nervosa. This eating disorder can have severe and potentially life-threatening effects on a person's overall health, including electrolyte imbalances, dehydration, heart problems, and more.
If you or someone you know is struggling with bulimia or any other eating disorder, it is crucial to seek professional help and support from medical and mental health professionals experienced in treating eating disorders. Early intervention and treatment can significantly improve the chances of recovery and prevent further health complications.
