What causes pale skin, fatigue and body tremors?
Patient: My 12 year old daughter often gets pale and shaky as well as fatigue. Her dad is a type one diabetic. We have had her tested with the 4 hour glucose test and it came back negative. She eats normally as well as drinks only water. She has had this problem since she was around 4 years old. Now she is involved in school sports as well. This occurrence happens more often when she gets hot. Any ideas? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  In this case, I will suggest a total blood analyses to have a check up that everything is ok. Especially, I will suggest a screen of thyroid hormones. It may be just her metabolism is itself like this and you don't have to worry. But first, let me have the total check up analyses and then let me know.   Hope the best.
