Hello Everyone. Im a 22 years old male. 5'11 about 150 lbs. I had seen an endo last month and he recommended me to avoid or cut back on grains under the diet portion of the treatment plan. There was no allergy reasons or anything like that. At that time I was fairly new to nutrition (still am now). So I took his advice too literal and all of a sudden. The following day I stopped all grains. I now realize I was coming from a high carb diet and grains have been a huge part of mine, and my family's life. Pretty much every meal. I also do not drink sodas or fruit juices, just water. I basically went 5-6 days with 0 - very low carb intake a day (40-50g MAX, some days less) in take. I had no simple sugar intake. By the end of the week I had low blood sugar sypmtoms....confusion, angry at people for no reason, almost fainting. I drank a bottle of OJ and went to the ER. They checked my sugar there and was normal (the OJ). Nest day similar sypmtoms and I checked my sugar at my Dads house (hes diabetic) and it was low 60s. I basically had some toast here and there the next week not knowing what was going on and still lacked a normal carb intake, nowhere near my usual when I look back. At the end of the second week I was feeling even more crappy with swings in my sugar levels. I ended up at the ER again feeling crappy. The doc told me I dont think its hypoglycemia. So given how I got myself into this situation (carb elimination) and my current sypmtoms (NO appetite like at all, kinda thirsty and urinate quickly after water ingestion, occasional low grade nausea), Is it possible I am in Ketosis? All basic ER bloodwork, CBC, coming back nornal. I tried to add a lot of carbs in yesterdays breakfast...actually more carbs than I probably had that whole first week...I broke into sweats, higher bp, anxious, etc...I read a post today that when trying to come of Ketosis you must slowly add carbs back in, if you do it to fast you well get a rebound effect from improper sugar and insulin (I guess thats what happened maybe). Im posting here because the docs have told me we dont know and are not thinking hyopglycemia. People on this forum who know diet...especially the body builders seem to know the best about this stuff. Is this Ketosis? How can I get out of it? How slow do I bring carbs back in? If anyone has any insight it would be great, im feeling like crap and have never "carb cut" before. Thank you I appreciate any help you have no idea.
