Thanks for your question. It does sound as if you have enough experience with this sort of problem, both personally and in your family, to understand that this is something that needs to be reviewed further with your doctor. There are different explanations for being low in some vitamins and minerals. One of the most obvious answers is that dietary intake can be a cause for being low and also for feeling run down, losing hair, losing weight, etc. If you are eating a regular diet and have not had problems before, this is less likely to be the cause all by itself. Another potential source of the problem could be with regards to your GI tract. As you have a family history of problems in this area, and have also been having some abdominal pain, this would certainly be something that warrants more attention. Your doctor will be able to order appropriate tests and ask the appropriate questions to determine if further workup is needed to determine what could be causing these symptoms. Anemia can be a cause of many of your symptoms, as can thyroid problems and a host of other possibilities. Please speak with your doctor about this.
