I had some blood tests done at my GP after feeling light headed for a couple of weeks (thought to be due to Labrynthitus), I went back today for the results expecting them to be clear and found that I have a severe vitamin D deficiency and also my liver enzyme levels were slightly elevated although all the other liver tests were ok. I am to have the liver test repeated in 4 weeks. What could this mean I am so worried that it's serious. I am a 33 year old non-smoking, non-drinking female. I don't have any other symptoms.
