I'm a 41 year old woman from the UK. I was diagnosed with thal b minor trait when I was about 12 after it became apparent in some other members of my extended family. Initially I was ordered to take high doses of iron by my gp. I stopped taking it after it made me quite ill. My gp told me I was a stupid girl! I ignored him anyway as I found out that iron was an inappropriate treatment. I've always suffered with fatigue, dizziness and migraines as do the other member of my family with thal. We put these symptoms down to our thal, even though we're told its asymptomatic and we just get on with life. Anyway, after discovering a message board discussing thal minor and its 'symptoms' I started taking folic acid. Literally overnight I felt like a different person. Full of energy, no brain fog, firing on all cylinders! I just wish I'd known about foilc acid years ago. The area I'd like advice on is that I have two sons. My eldest has been tested years ago and isn't a carrier. My youngest is just like me; pale and easily tired. I'd put money on him being a carrier. So I went to my gp yesterday asking for him to be tested for thal and was curtly informed that 'we don't authorise tests for genetic disorders that require no treatment'. I explained about the folic acid and how it had helped me and the gp almost screamed at me that I shouldn't be taking it. What i want to know is; would folic acid be harmful to my son if he took it? He's 13 by the way. I do have another appointment with a different gp who is supposed to be a specialist in haemotology about this but I'm thinking is there any point in me taking him if the UK guidelines are 'it's not a problem and there's no treatment' Sorry to go on, but I could've cried yesterday! Hope you can help. Thanks.
