 Hey guys, this is Dr. Ahmed Ergin. Today we are going to do something really interesting and scary. My heart rate is already up and I didn't think that it was going to be like like that nerve wrecking and but what I'm trying to do today is I'm going to give myself insulin. I am going to drop my blood sugars. I had, don't worry about it, I have, I have a nurse by me. Something happens. She's gonna intervene if I pass out or anything like that. She's gonna give me the glucagon. You found my responsive, which by the way, every diabetic on insulin should have this glucagon. This is a new glucagon ready to go called GVAC. I am not diabetic. My goal is not go down to 10. By the time I'm down to 7 or 60, I will start feeling it and my goal is to go below 50 and I want to feel what my patients feel when they go low and now I understand how my patients feel when I tell them that I'm going to put you on insulin. I can feel the fear that they're going through. That's real and I am going to give that shot to myself and I'm going to put myself to hypoglycemia, which is low blood sugar. I always teach them how it feels and how to fix it and let's see if I can take it. I'm going to do that and today my other goal in addition to putting myself into low blood sugar situation and feeling it, I also want to test continuous glucose monitoring systems in the market. So Freestyle Libre, Dexcom G6, and Guardian from Metronik. These are the three leading brands and I want to see in a real life situation with the real low blood sugar if they're accurate because that's what I prescribe for my patients and I want to know which one works best. I am going to do a finger stick of course from a quality brand that I know is very reliable and of course you can tell by my symptoms. I'm going to start feeling sweaty, shaky, heart racing and I'll probably lose my collar. I may feel dizzy. So I decided to use Fiasp. So Fiasp is the fastest acting insulin analogue right now or for the among the short acting insulin. So I decided to use this because guess what I'm not going to wait another two three hours for my blood sugar to drop. I'm going to be really generous with this insulin. So let's do the priming first. Okay two units did work but I'm going to a little more okay just to make sure. All right so go go go go go. All right I'm gonna okay wow that's going to be big. It's going to be 30 units. Now don't do that at home guys especially if you're diabetic you know you know I'm healthy that's why my body is trying to fight it but this 30 units I think we'll bring it down. Okay let's go. Alrighty okay so that's gonna oh yeah oh what I like about this Fiasp the push that plunger is so easy compared to himalogue and let's see if it is as fast as they say the studies say that it starts in in two minutes to act and it peaks relatively faster but uh we'll see guys. Okay so my blood sugar right now on the Libre is 94 and on the Dexcom is 110 and on the Guardian it is 118. Again Freestyle Libre 2 is reading everything considerably lower compared to other CGMs. Good thing or a bad thing we'll see but I think in the you know if you remember it gave me a couple false alarms false low alarms we'll see how that's gonna go this time and I'm hoping that I'm gonna really go low and we'll see which one picks up faster I'll keep you posted I'll keep you updated in a second. I think Fiasp is working faster so it's been 40 minutes and I already got a low alert from this guy from Freestyle Libre. Yeah let's see scan it scan it okay oh it says 56 I can't believe it's 56 I don't feel like 56 I'm sorry Freestyle that's cannot be true because I don't even feel it as a healthy individual if it was 56 I would be like perspiring right now now Guardian showed that you're not low but it's predicted so you're going low and as you can see here it says 76 and there's one arrow down it shows me that I'm going down now super fast but I'm going down one arrow down which means that you know right around one to two milligram per deciliter in 30 minutes that's gonna be 30 to 50 lower than this 76 so if it goes like this that's how you interpret this you may be down to at least 46 within 30 minutes now that's not good so if you were to have bad if you should do something about this right so let's let's look at the dexcom of course let's look at what the dexcom says here dexcom says it's 95 and it is stable not so sure about that I used to really love dexcom and people love dexcom but I'm surprised that dexcom didn't pick up on that that my blood sugar is actually going low now I also feel like a little butterfly healing like a little bit of anxiety feeling and I think that's my contrary hormones are kicking in right now and I want to see what my finger stick shows I think that's probably we'll see which one is the closest um that's the whole point of doing this experiments today all right so I'm excited let's see what it shows oh wow it is 60 guys can't believe it it is 60 uh well here's the deal guys I'm gonna give some credit to freestyle libero 2 because this says 55 and this says 60 which means that I'm low maybe because I'm normally running around 90 60 may not be a big difference I mean a lot of people if they are going from 200 down to 90 they're gonna feel it you know your body read your body doesn't understand numbers your body knows a difference so um but that's good fias put me down in 40 minutes I like that so it's gonna actually peak around an hour so I'm hoping to go really really low uh and I'll see if dexcom picks up on this uh I'm hoping that it will because if it doesn't it will be a big disappointment so we'll see what it how it goes I'll keep you posted okay guys I start feeling funny so uh dexcom is picked up right after I uh it was 110 and after that it went down to 82 and it's showing the arrow as you can see it's not totally down but it's showing oblique um which shows you you know pretty much the same thing as one arrow down with the metronik um so what I feel right now is um it's kind of funny it's kind of a funny feeling it's kind of a panic feeling you know that I don't know when the rush that comes to you that's how you feel um and let's see what that is right now it says 53 I think that's a little exaggerated I don't think I'm 53 um I'm gonna do another finger stick just to see yeah I feel uh busy it says 43 okay well am I 43 I know I feel busy I feel like the lights are are kind of too shiny a little too bright uh it says 43 here on the meter and it says 52 on the librae 2 librae 2 this is the new librae dexcom says it's 82 and according to guardian it is 63 and going down so I think um I feel low right now and I'm sure I'm below at least 70 and dexcom shows that it's 82 right now and it's going down um it's predicted that according to dexcom and I would be low down to below 60 in the next 20 minutes according to this and let's see if I have any hand shaking a little bit a little bit my heart rate yeah it's up let's have let's find out what it is according to this my heart rate is 116 124 yeah I feel the shaking I guess gonna go lower we'll see let's see how low I will go before I pass out that is the deal and if I pass out uh I have the guca going here I chose g-vote because I don't have to you know reconstitute the whole thing and I can inject to myself uh so that's the beauty of it because if you're down to 77 on dexcom and I think dexcom is probably closest to how I feel and I think the librae 2 let's see what it is it's 51 and I think a little over exaggerated um it's predicting low which is good but I think it is um predicting a little too low let's see what the guardian shows according to guardian I'm down to 58 and maybe it's true I don't know maybe it's true uh dexcom shows that I'm 77 still it checks it every five minutes of this shows now the freestyle librae 2 it says 50 and I'm going down so we'll see what happens when I'm down to 40 the point that I'm trying to make here number one is I'm trying to feel how you guys feel and number two um although as I said you know I may not feel exactly how you feel but at least I want to understand um how a nasty feeling is the the bottom line is it's a horrible feeling uh no matter what you feel it doesn't feel good when you choose a meter and then I told you about the guardian right guardian shows I'm gonna give you my final comments on this um it says 59 on on the uh on the guardian metroni and I'm gonna do this one more time I think it's gonna come around the same probably older remember blood sugar drops faster than your inserthitial fluid all the time so um monitoring your blood sugar in a situation like this is your best bet I'm back up to 71 once it's almost midnight till 2345 and uh gee I was like getting into bed and I felt like something weird and like something in my chest feeling like anxiety my I'm feeling extremely tired and weak I was like oh that was a long day I know that but then I uh start feeling hot and I'm like oh god let me check my blood sugar and then it was like below 60 I just had some food uh and it's like trying to come up but uh that was the guardian that I just showed you here uh well vexcom shows 71 as it's again dragging their feet trying to trying to come up I want to see what my finger stick is yeah 67 so it's coming up um but I I think when I felt it was below 60 so another lesson so if you had a low check your blood sugar again uh after you fix it with simple sugars not with chocolate not with uh candy bars like uh sneakers and stuff but I would go with the finger stick as close as the truth 67 vexcom says 72 pretty close the guardian says 61 is more dramatic I don't know if that's correct or not but the bottom line I think I went down to at least 60 maybe 50 um and freestyle libre was the first one to pick up on that uh but I didn't even feel that I was low uh so if you are concerned and if you want to know and never want to go low maybe freestyle libre is the way to go uh if you want to know that you're going low um but you know you don't want to be all ordered all the time or or you know 70 60 blood sugar is not only that dangerous you don't want to know that you're you're you're getting false alerts for example when it's when it's in reality 70 for example this now says 74 on dexcom um but you know with um with the guardian for example it said 60 the dexcom says you're right around 70 the finger stick showed 71 dexcom shows 74 maybe dexcom maybe your choice if you for example the really do not want to get too many false alarms and get like if you get an alarm that's just pretty much real uh so I think they made the freestyle libre and guardian a little too sensitive um the problem with the guardian you still have to do you still have to do two finger sticks to calibrate and if you don't calibrate it just quits on you and that's the problem and you still have to do finger sticks with guardian now of course another big competitor to dexcom is freestyle libre 2 which is new uh doesn't have an app yet that's a problem um but they have this and I've measured on this according to this I mean it's uh it picks up low sugar I think it gives too many false alerts but I think sort of overall still a good product if if your budget allows this and if your insurance covers this whatever uh it is still a good product if you want to pump definitely go for dexcom um but if you are just wanting to monitor your blood sugars and you know you just want to know that you're not going to danger zone uh you want to keep your blood sugars about 100 um then that's maybe then freestyle libre maybe your choice um but again I think overall um dexcom has the best features right now um and I think it is still a very accurate uh better little false alarms if you get a low blood sugar alerts that's going to be a real low uh so I hope that video helps guys and uh again make sure that you leave comments uh we want to hear from you as well uh and we will uh talk to you and see you in the next video
