I've researched the digestive process and understand now why my hunger isn't there. I'm 9 weeks out and have had to set 5 timers on my phone to remind me to eat or snack. There is a hormone called Grehlin in your stomach that secretes more as you get hungry. Once you eat it stops secreting. In a sleeve you have 80% of your stomach removed. It totally throws off the production of Grehlin. Not only is your stomach healing from the surgery (which drinking your Protein to 60-70 gms a day is important. Not just for healing but also for stabalizing your whole system.) I've read that there is a risk at 6-9 months out that you could start losing your hair (it does grow back) I also read that if you take a lot of Protein in from the beginning that your hair won't be affected. I'm hoping that's the case. I'm up to eating about 700-800 calories a day. I read labels and shoot for food low in carbs and sugar. My only vice is yogurt (which I never used to like). It has good protein and even with the "light" yogurt there are still 11 gms of sugar. I've discovered my "ate too much" button a couple of times and it wasn't pretty. It does change as you heal. I started out being able to drink 1 oz. and now i'm up to 4oz of solid food. If you are eating/drinking like they say to then your body should signal you before you get too full. The expression "your eyes are bigger than your stomach" is very true in this surgery lol.
It could be acid. I had hat problem for three weeks until I spoke to my doctor about it. I took some Zantac and BAM... Hunger pangs went away! ???? in other words, I had so much acid that my body was confusing it for hunger.
