I wish to respond to Loobie's comment,
Like you said, your stomach is growling, you know you need to eat, but you have no appetite
Is it the stomach
or could it be gurgling on the left side, above the waist, such as I have and think is the pancreas
? Excess insulin, anyone?
I also never have an appetite--for a good 10 years now. I have recently heard that insulin acts in the brain to reduce appetite. I need to look into this further--wish I were an endocrinologist!
Once again, I urge those with such symptoms to request a "fasting serum insulin test"--not a test for glucose, but INSULIN. Your family doctor or internist can order this, you don't need a specialist. Mine is elevated at 12, I would guess yours is too.
