caffeine

I am 2 years out from my RNY. Started to gain back weight about 8 months ago. Now at a 20 pound gain! I went to nights at work, and started downing the coffee, and have continued to do so. A dietician said that anyone who is 2 years out, gaining weight, should cut out all caffeine. Something about the caffeine makes the pancrease produce extra insulin. I have been hypoglycemic for awhile now. Any ideas?

All I know is caffiene is a diuretic and doesn't help with your water intake. I've always heard that for every cup of a caffienated drink you need to drink 1 1/2 cups of water. Also, a nurse at our last support group meeting said that RNYers have to be very careful about drinking too much water, that it tends to give us ulcers more frequently. I'm not sure if she meant in the early stages or forever. The guy asking the question was a newbie and was being admonished for drinking so much coffee. Don't know about the insulin question.

I've never heard that caffeine makes you gain weight - especially since diet pills are loaded with it. Has anything else changed with your diet or exercise regimin? Tracy

Monique, I've never heard this, I'll be seeing if you get other replies. For me coffee (whether decaf or full caffiene) tends to make me not want to eat, it is known to be a diuretic and also a appetite supressant. Dana

There is a medical journal article: Kerr, D., Sherwin, R.S., Pavalkis, F., Fayad, P.B., Sikorski, L., Rife, F., Tamborlane, W.V. and During, M.J. 1993. Effect of caffeine on the recognition of and responses to hypoglycemia in humans. Annals of Internal Medicine. 119(8):799-804. http://www.annals.org/cgi/content/full/119/8/799 "Conclusions: Acute ingestion of caffeine is associated with sympathoadrenal activation and awareness of hypoglycemia at a glucose level not usually considered hypoglycemic. Our data suggest that individuals who ingest moderate amounts of caffeine may develop hypoglycemic symptoms if plasma glucose levels fall into the "low-normal" range, as might occur in the late postprandial period after ingestion of a large carbohydrate load. " So that sounds like if you ingest a bunch of caffeine... you might feel hypo even if your blood sugar is in a low-normal range which is the range that often blood sugars fall into after ingesting large amounts of carbs.

I was told not to drink or eat anything with caffeine post op cause it increases you risk of stomach cancer. this is the first I have heard about it making you produce extra insulin.

Thanks to those *****plied. I cut out caffeine to test this theory. We will see. I also cut out my pasta's, breads, and refined carbs. I am praying to lose some weight here. I need to lose 15 pounds to feel comfortable with myself again.
