Hi Dear,
Bulimia is something serious and can have damaging physical effects. I do not wish to scare you here, however these are the know physical effects of bulimia due to vomiting:
-Dental problems: destruction of tooth enamel which can cause cavities and the loss of teeth
-Electrolyte imbalance: These are necessary to and essential for our body to continue working. The loss of potassium can cause fatigue and spasms and severe cases can led to kidney failure, irregular heartbeat and death.
-Gastrointenstincal disorder: This could be what you are experiencing right now.
And then there are nutritional deficiencies and salivary glands swelling.
As the others have suggested, I recommend that you go back to your doctor and talk to him about this. If ever you need to talk you can
pm me.
