I have recently been diagnosed with Celiac Disease and H.Pylori infection. Both affect the small intestines, and over years of damage, prevent us from absorbing nutrients, there for weight loss and Hunger, and Binge eating. You should go to your doctor get a vitamin test, and ask her to test u for H. Pylori, it is so very common, and Celiac is also, if you are eating soy sauces, or anything with Wheat, barley, or Rye extract this can cause harm to your intestines.
Symptoms can surface at anyage so I would check that out,,,It could at least cancel out any deficiencies.
