You sound like me. I'm very sensitive to slight fluctuations in my sugar, I go low and high, and I'm most comfortable at right around 100. I have prediabetes (metabolic syndrome x or fatty liver disease) and that caused me to become very obese. You need to have your liver enzymes checked, and if they are elevated, they should give you an ultrasound of your liver to check for fat or other problems. Also, you need to have your blood insulin level tested, it is the only way to check for hyperinsulineamia (low blood sugar) and a glucose tolerance test to see how high you spike. High blood sugar can make you feel the same as low blood sugar and vice versa. It's not real clear. These tests are critical, espeically with your weight gain. They also need to test your TPOs (antithyroid antibodies) even if your thyroid level tests are normal to see if you have hashimotos. You can be "euthyroid", which mean s you have a normal thyroid level (TSH) and be very sick and have your body and thryroid get completely destroyed by hashimotos. Your endocrine system compensates and a good endocrinologist knows that the antibodies matter more than the TSH in this case. Your weight gain and abnormalties in blood sugar can come from your thyroid. It probably isn't related to your diet, just a change in your body that causes your liver to store fat rather than to burn it, called fatty liver and it is part of diabetes and metabolic disorder, it is all the same thing and it often occurs with hashimotos and othe endocrine disorders. If your weight is around your belly and more on the uppoer part of your body, then liver is a good guess. I would try to get some of these diagnostic tests done to find the cause of your weight gain before you get like me because even when they treat you it is so hard to get your liver to burn it. I take glucophage for my fatty liver NOT for my diabetes, but it gets the sugar out of my liver, lowers my superhigh insulin level and prevents swings either way in my sugar (low or high) and keeps it dead at 100. Take care and let us know what happens.
