Changed Diagnosis

Hi. Before you go onto insulin (which you have done), a c-peptide blood test will tell the GP what your natural insulin level is. I had one done privately which proved that I had very little natural insulin and, as I knew as I was under-weight, that I wasn't insulin resistant. Those who are insulin resistant will normally have high levels of natural insulin present. A GAD blood test will also show whether you have the most common islet cell anti-body present but it can give false negatives; this anti-body kills islet cells causing late onset T1 (LADA). A lot depends on your weight. If you are overweight, then you may have some insulin resistance and initially you would need quite high levels of injected insulin. With a good low-carb diet this should resolve itself and injected insulin can be reduced. If you find quite low levels of injected insulin work well i.e. you have good insulin sensitivity then you are not insulin resistant and just need to match insulin to a sensible low-carb diet. I think 44 daily Lantus might imply some insulin resistance, but I'm not an expert. I'm on 10 units Levemir which is all I need for basal.
