Hi. I Have The Following Symptoms And Cannot Find Cause:

Hi. I have the following symptoms and cannot find cause: gradual weight gain right around middle, bloating after eat and feeling of fullness even after drinking water, thirsty, cannot sleep and when I do sleep I don't stay asleep. I've cut out bread and rice because bloating is bad after eating these but now bad after eating sugar and other things. Im on hypothyroid medicine and thyroid levels are supposedly in range. I am in menopause. I've gained about 30 lbs within a year, and had these symptoms about 2 years now. Gastro tests all normal. Checked gall bladder and pancreas. Had slight pancreatitus attack in Jan and enzymes out of line but only happened once
