Mark Oldham replied to elaine peterson's discussion 'Oops!' in the group Dexcom Users
"I go in the hot tub almost every night with mine on. It seldom has a problem. It will get dashes for the time it is under the water because the water blocks the signal to the receiver (which I leave in the house to keep it away from the water). But,…"

Mark Oldham replied to Kian's discussion 'Travelling and vacation with Dexcom?' in the group Dexcom Users
"I use it in the hot tub at 104 Deg for an hour a night and a time or two a week in the wet sauna at 160-180 at head level, never measured at at the transmitter level (bellybutton) but it is somewhat colder, for about 15 min. I don't take the…"

Mark Oldham replied to Kian's discussion 'Travelling and vacation with Dexcom?' in the group Dexcom Users
"As far as swimming, I swim with my sensor on all the time. In fact, I spend about an hour a day in the water, usually in a hot tub. Of course, the little computer that reads the numbers isn't water resistant, so keep that part away from the…"

Mark Oldham replied to Dondi's discussion 'Last night around 1:30 A.M. I awoke to the sound of my Dexcom 7 Alarm going off' in the group Dexcom Users
"If I lay on the sensor, or if I go to sleep dehydrated, it will go low on me at night. If it goes low from laying on it, I get up and move around for a few minutes, drink some water, go back to bed, without calibrating, it is back on target within a…"

Mark Oldham replied to Laddie's discussion 'Anyone noticing a shorter life on the receiver?' in the group Dexcom Users
"I charge it on Wednesday night and Sunday night. I have forgotten to charge it on Wednesday and had it warn me on friday morning and go dead by Friday Night. So, I guess I am getting at least 4 days out of it."

Mark Oldham replied to alba37's discussion 'Any tips for a new CGM user?' in the group Dexcom Users
"my tips to get the most out of it.. Put SkinTac on and let it fully dry before putting a sensor on, do not wipe with alcohol before putting on the skin tac (it has alcohol in it). do your first calibration when you think your blood sugar is stable…"

Mark Oldham replied to Danielle's discussion 'Allergic reaction to adhesive?' in the group Dexcom Users
"Have you tried putting SkinTac down on your skin and letting it dry before putting the sensor on? If I put a sensor on without SkinTac, I get blisters. No problems with SkinTac, and the sensor tape doesn't start to pull off until well after the…"

Mark Oldham replied to Laddie's discussion 'How to keep transmitter site dry?' in the group Dexcom Users
"I have had problems (seldom) with water getting between the transmitter and the sensor causing bad readings or "sensor failure". But, simply removing the transmitter from the sensor, cleaning it with an alcohol pad, dabbing any water out…"

Mark Oldham replied to AlexJ's discussion 'Can sensors still be used after the expiration date?' in the group Dexcom Users
"There are no brains in the sensor that tells it when to expire. It may not be as accurate depending on the conditions it has been stored in. But, if it has mostly been stored in a dark place (like the box it is shipped in) and been kept at 70ish…"

Mark Oldham replied to jm's discussion 'Dexcom glue leaving red dot marks' in the group Dexcom Users
"I have that problem. It started for me after a few sensors (the first couple didn't cause the problem). I don't think the glue changed, I think my body became sensitive to it. I put Skin-Tac down before putting a new sensor on. It creates…"

Mark Oldham replied to HannaPancreaticallyChallenged's discussion 'Canadian :( Should I just buy Dexcom in the UK?' in the group Dexcom Users
"If you spend so much time in the water, why aren't you considering the Omnipod? I would recommend the Omnipod WITH the Dexcom for you. I spend a half hour a night in the hot tub with both on and have never had a problem with either. Do watch…"

Mark Oldham replied to Jodil's discussion 'Checking blood sugar in public'
"At work, if I need to test, and someone else is in the room, I will say something to the effect of "I have to test my blood sugar, if the sight of blood bothers you, you need to leave the room for a minute. Anywhere else, I am sorry if I offend…"

Mark Oldham commented on Valerie's blog post 'If I seem to act 'different', people assume my levels are off...can you relate?'
"You need a CGM (I use Dexcom). Then you can immediately pull it out, point to it and say "nope, normal, see, been normal for hours" and continue on winning the argument..."

Mark Oldham replied to MaiaJane's discussion 'Gushers!' in the group OmniPod Users
"Leaking blood has only happened to me once in the 122 pods I have used so far. Of course, that one time was when I ripped one off at work because it ran out of insulin and the pod was screaming and I didn't have my controller near by to shut it…"

I've got a problem many diabetics would like to have. My A1c as of yesertday was down from 5.3 to 5.0. My diabetes nurse insists I try to get up to 5.7.

Hi there, friend. I am leading a very sedentary life here in central PA, doing no more travel, and spending most of my waking hours caring for my lifelong friend who is suffering from dementia. I am in good health (My A1C is hovering around 5%) and I attribute that to two things; I found an excellent diabetes support team at a wonderful hospital only an hour away from here (Geisinger Health Systems in Danville, PA), and the Dexcom Seven Plus which I wouldn't want to be without even though Medicare doesn't pay for a penny of the cost so it all comes directly out of my own pocket. Thanks to NewsMaker's extremely generous health benefit plan I am doing OK, thoguh lol. How are you doing?
