Tolerance Changes @ 2yrs out

I was 2 years post op as of 8/16.  I have never dumped, I can eat a LOT of food, carbs have never bothered me.  The last few weeks I have noticed some changes in my tolerance.  I knew about Reactive Hypoglycemia, so I am careful with my sugar intake.  But the last couple of weeks, apparently carbs are bothering me?

Example -  it is a norm for me to have oatmeal (Bob's Red Mill - not instant) with peanut butter and sometimes a banana - but always the peanut butter for protein. Tuesday and today I had some for my pre-gym meal and both days I had RH symptoms.   Tonight I had a thin crust slice of pizza and about 30 minutes later sweat drizzling down my back and dizzy as all get out.

Any other folks  a little further out experience tolerance changes beyond just RH with sugar?
(those of you who may not know me - don't panic about my intake.... Dietitian is cool with everything I am doing because she knows my level of training  / workouts  ;)  )

RH is frequently triggered by anything high in carbs, not just sugar.  I've had it after eating crackers, popcorn, stuff like that.  In fact, I never eat things real high in sugar because I do dump.

In a way I am quite ok with having consequences... because I haven't had them at all and I could tend to get a little crazy with my choices.  It just totally caught me off guard that it would start so far out. And I guess I never considered "real" oatmeal a simple enough carb to cause the reaction. I obviously need to pay more attention about that stuff!

Kelly  -   since I have been anemic and am on iron scrip (ferrous sulf 324mg 3x day), do you think this could be iron related? I started my period on Tuesday night and all this seemed to get really rough Tuesday morning

This is happening to me also. I was 2 years out on 6/24. Last week, I thought I was having an anxiety attack & next thing I remember was coming to in the hospital parking lot. My husband found me unconscious on the kitchen floor face down in a huge pool of blood. I was unconscious for about 20 minutes. My blood sugar was 50 when I got to the hospital. I ended up needing up stitches in my chin because I hit it on the way down.
Today I got a glucose tolerence test. My 1 hour result was 320. My 2 hr result was 142 & my 2.5 hr crashed to 42! Things that never bothered me before are really messing with me. Good luck

Ugh... that does NOT sound like where I want to be!!  One night I was driving home and felt the shakes / sweats coming on.  I was close to my parent's house so I stopped in and used my mom's glucometer.... 47.   I have an appointment with my dietitian in a couple of weeks, I guess I might need to ask her about this.  :/

 If I eat something like oatmeal without adding an adequate amount of Protein powder or if I wait too long between meals it knocks me on my butt. I try to eat  every 2.5 -3 hours. I keep Glucerna tablets close by because I feel the room getting dark around me and know I don't have much time to get my sugar back up.

I put 2 Tbs of peanut butter in my oatmeal and it has been fine in the past. I guess that is what caught me off guard.  I have emailed my dietitian, because I have 2 Sprint Triathlons coming up in the next few weeks and I don't know how to eat for them!

Yeah, I've had a few foods -esp higher fat or higher natural sugars -  just randomly disagree with me, kinda like a mini-dump, seemingly out of nowhere. And then the next time I try them, I'm fine. But when I go much higher on carbs than I'm used to (like on vacation or eating a bagel), I get the worst gas EVER!!  So that's aversion therapy for me (and anyone within 20 ft).

I hope your RD gives you some insight on how to balance training with BG issues, but what they advise us in long-distance running is upping fats 10 days before a race and upping carbs 3 days before - so, to space things out that slowly with protein accompanying your carbs & fats should allow you to not worry about bonking but also save you from the high/low swings.

I will try the spacing things out... I have a full course "Dress rehearsal" for my Sprint Tri, so if I goober up my nutrition on the first one it is no biggie.
