I ended up in the Emergency Room 3x back in April, May & June for odd pain in my right side and by the 3rd ER visit I saw on my lab report that my Ketones were high. Well I didn’t feel like eating around all those times due to that pain in my right side and one week I actually wasn't eating hardly anything. I lost about 15 lbs without even trying. I read that a person can develop diabetic ketoAcidosis due to high ketones and that a person should go to the ER if they suspect their ketones are high, Well I was already there at the ER with unknowingly high ketones. I read when you aren’t a Diabetic (which I’m not a diabetic ) high ketones is caused by your liver breaking down fat for fuel for energy due to a person not eating enough carbs to sustain themselves. Symptoms of it (among other reasons) are stomach pain which I had while there in the ER as well. Everytime I ended up in the ER I was there for 6-8 hrs waiting for care and wasn’t eating. Granted I wasn’t hungry either because I was in pain although once the pain subsided I did try to eat. I have been wanting to lose weight but that is not a good way to do it and I didn't do it on purpose.
