Extremely low triglycerides

Hi

I've got chronic autoimmune thyroiditis and was diagnosed hypo Dec 2009 and put on levothyroxine. The dose was fine but recently I've got ill again and this week the dose was increased after TSH had risen to 4.77. Symptoms aren't as bad as last year, but horrible feeling in my heart and high diastolic BP (heartrate 60s and upper BP number fine). tiredness etc. I'm not worried - the extra thyroxine will help soon.

My question:
My heart is always the first and worst symptom when I go hypo: palpitations and high diastolic. All my life I've had far too few triglycerides but normal cholesterol, although these days my HDL is too low. The lipids have remained stable despite the thyroid problems. I'll give you my results along with the normal ranges from 17th Dec 2010:

Triglycerides 0.29 (0.70 - 1.70 g/l) TOO LOW

HDL 0.39 (0.40 - 0.60 g/l) TOO LOW

LDL 1.22 (< 1.15) SLIGHTLY TOO HIGH

Ac antithyroglobuline 25 (< 5 UI/ml)

Thyroglobuline 1 (5-60 ug/l)

I'd be ever so happy if anyone could tell me what to do because my doctor ignores the triglycerides but there's a minimum number for a reason I expect. Also that thyroglobuline thing, is it low because the anitbodies have attacked it? I've tried to drink more alcohol to raise my triglycerides, and have got into the habit of drinking a glass of white wine each day now, previously I hardly drank alcohol.

If relevant: female age 44, slightly overweight due to hypo, otherwise usually BMI about 24.

Thank you so much!
