I would like to know why someone with an eating disorder often feels nauseous and like about to faint ? When they do labs everything turns out to be fine. Does this mean that although the person has an eating disorder, she is physically out of danger?


Hi: It's difficult to say


It's difficult to say what might be causing the nausea and faint feeling. Results from blood work should be able to rule out an electrolyte imbalance which could cause those symptoms - however, as you mention the lab work has not shown anything remarkable.

Of course, there are a number of other medical issues which could be causing the troublesome symptoms. The most important matter here, is that it is not normal to feel nauseous and light headed. An eating disorder places an enormous amount of strain on one's health and wellbeing, and this could be the body's way of letting you know that all is not well.

It is really not possible to determine exactly what is causing the nausea and faint feeling without seeing a doctor, as there are a large number of possibilities to consider. Conditions such as pregnancy, stress, anxiety, low blood sugar, stomach disorders, thyroid problems, or other side effects from the eating disorder can all play a role.

It is really important to follow up with a physician in order to rule out any other possible causes for the nausea and fainting. Feeling nauseous and light headed is unpleasant as well as worrying, and although the blood work will have ruled out some conditions, it would be nice to have an explanation for what is going on.

An eating disorder is always damaging both to one's physical health as well as mentally and emotionally. While "normal" blood work may be an indication of no immediate physical danger, this should not be interpreted to mean that the person's physical health is not at risk.

I would urge anyone who is suffering from an eating disorder to reach out for professional help. You do not have to live with the constant worry about your physical health, or the stress of coping with an eating disorder.

Hope this helps a little.
