Hi cj, yes, inflammation, infection, malignancy can increase your ferritin iron levels - even sometimes a cold.
Your sister, being a first degree relative, is entitled to a genetic test as your haemotologist says. A 2nd degree may have to pay a bit if their levels are not high enough - YET! They should keep being monitored.
Your country may have an organisation for Haemo and they might have a letter which you can print off to take to your relative's dr describing the condition and how the person in question should have a genetic test. We have one in Australia which has the letter.
Another interesting site for which I cannot give the url as this website holds up processing if the content includes a website, is the Iron Disorders Institute, go to Forms, and click on Hemochomatosis Reference Charts (2.27MB). Page 2/2 gives all the normal levels in Iron Studies, and lists all the organs that are affected by Haemochromatosis.
My first hemotologist told me about the molecular damage. He was an old fellow on loan to the hospital. I wish I knew then what I know now so I could have asked more questions. I did ask why, if I was now "deironed", did I still feel so tired, etc. He told me that because the damage had been done years ago with the deposits of iron destroying my cells at a deep molecular level, they will never be repaired, only prevented from becoming worse.
The only thing that has made sense to me so far - as well as some words of wisdom from a specialist cardiogist that I had to be very assertive to see - that even though there may be deposits of iron in my heart muscle causing these problems, the only treatment is venesections. They can't cut any of it out!!!
Bloating - I do wake up with fat fingers, which dissipates, perhaps it was a threat of arthritis which has been reduced because of your venesections. I mostly bloat in the belly area - tried lots of things.
Everytime I had ECGs nothing showed up because you need to be having a problem at the time of the ECG except one time I felt a 'ping' and the technician nearly fell of his chair and asked if I felt that, as my heart had skipped a beat. Other signs are a pinching feeling mid chest, and if you lie of your right side with your left arm across your chest, you could feel it IF it was happening at the time.
When I was first made aware of arrythmia by a dr listening to my chest, (like, i did not feel it!!), I was put on a 24 hr halter monitor and found to have extra 21,000 heart beats in 24 hours. The medication (beta blockers) nearly killed as it dilated my brain vessels and allowed the iron particles in - do not let them give that to you!
The specialist cardiologist said most people do not feel real arrythmia, but I learnt to recognise it and now put on a monitor strap around my chest and it transmits to a wrist watch device and confirms it. Most runners wear one of these to monitor their heart beats, so you will find them in sports shops.
