@Lost apetite; can you indicate if you testing your blood sugar regularly & are your readings within the accepted average? Split the one meal into two rather than one big meal. I think you also need to be seen by a Doctor.

not long ago i too totally lost my appetite-with me it turned out to be associated with kidney failure.Talk to your doctor and get checked out

I have lost apptait but I still take my sugar and take my insulin I would never stop taking my medication without my doctors say so

I had similar symptoms in 2015, which was eventually diagnosed as gastroparesis, a diabetic complication os slowed digestion, in which small amounts of food resulted in feelings of fulness and nausea. It was diagnosed through tracing the progress of radioactive food through my gut. Treatment was initially with motilium, and I now cope through a high fiber diet and eating certain foods such as figs and dried apricots.
