Libre reads lower on right arm

T diagnosed [emoji[emoji6][emoji6]]. UK resident. Self-funding libre sensors since [emoji[emoji6][emoji6]].

I alternate arms when a sensor ends. Over the past six months I’ve noticed that I get lower reads when I apply the sensor to my right arm. Time in range goes over [emoji[emoji6][emoji6]][emoji[emoji6][emoji6]]%. When I use my left arm reads go up and time in range drops as low as [emoji[emoji6]][emoji[emoji6][emoji6]]% ([emoji6][emoji6]% at Christmas!)

Anyone else get something similar?
 
Type two diagnosed thirteen years ago. Self-funding libre two sensors for the past two years. Right arm readings are lower than left arm by a noticeable margin.

I have used Libres in the past (now use Dexcoms). I always used them on my left arm as I consistently sleep on my right. Sorry it doesn’t answer your question but thought I should reply as I’d replied to your comment about the glitch.

Thanks Rachox, I knew about how sleeping on sensor can reduce reads dramatically after waking up one morning and finding my reads had tanked several times one night.

The lower reads on my right arm happen throughout the day, not just at night when I’m sleeping. I get **** near normal fasting reads, fours and low fives and spikes are more like gentle slopes. I feel like a diabetes management queen! Then I swap to left arm and all goes to pot for two weeks.

Any theories? Maybe one arm has more fat than the other? Left arm is nearer the heart?
