I still worry a bit about you have some form of diabetes.
It is nice the hospital test shows no problems, but it doesn't fit with reality, where you report you have several symptoms.
I copied these symptoms for diabetes 2 off Lilly's website for diabetes.
problems with sexual function
dry, itchy skin
slow healing of cuts or sores
increased hunger and thirst
numbness or tingling in hands or feethttp://www.lillydiabetes.com/pages/symp ... sis-2.aspx
It seems to me several fit with your symptoms.
I am well aware that one may get quite hypochondric by reading the net, and think one suffers from all manner of diseases. Lilly is a major pharma company, so the list here is "valid" (there are many other sites where you think people don't know what they are talking about).
The symptoms you describe do not seem to be food allergy.http://www.mayoclinic.com/health/food-a ... N=symptoms
Maybe I should mention I have a degree in chemistry, but as said before am not a doctor.
People often think various illnesses are caused by "factory processed food". I dont mean to get into a long discussion about that with anybody, I respect people who want only natural foods, I just mention it should not cloud the search for what might be wrong with you.
The test did not yield a diagnosis or "result" like "this value is bad, it shows you suffer from XYZ, and here is how we will treat it". The test was inconclusive, and is not the same as showing "you are healthy". Because clearly something is wrong, according to what you describe. It may be something you can live with, but it is not normal.
It is good advice you got to get a glucose meter and keep a diary. It seems something is going on with your blood sugar.
From the same Lilly page the following is mentioned about diagnosis of diabetes
In the U.S., type 2 diabetes is frequently not diagnosed until many years after it begins, when complications appear. Approximately one-third of all people with diabetes may be undiagnosed. The American Diabetes Association (ADA) recommends that people age 45 and above be tested for diabetes at least every three years. Adults who are overweight or obese and who have one or more additional risk factors for diabetes should also be tested at least every 3 years.
The preferred test for diagnosing type 2 diabetes is the fasting plasma glucose (FPG) test.1 This blood test requires fasting (no food or drink except water) for at least 8 hours and is usually done in the morning. Other tests are the casual plasma glucose test (a blood test taken at any time of day without regard to time since last meal), and the oral glucose tolerance test (OGTT; a blood test taken at 2 hours after drinking glucose dissolved in water).
A diagnosis of diabetes is made if a person has any of the following test results1:
FPG is 126 mg/dl or higher; or
Diabetes symptoms exist and casual plasma glucose is 200 mg/dl or higher; or
Plasma glucose is 200 mg/dl or higher at 2 hours during an OGTT
If any of these test results occurs, testing should be repeated on a different day to confirm the diagnosis.
What is pre-diabetes?
Before people develop type 2 diabetes, they almost always have "pre-diabetes" — blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes. There are 54 million people in the United States who have pre-diabetes.2 A diagnosis of pre-diabetes is made using the FPG test or the OGTT. Depending on which test is used, pre-diabetes is categorized as either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT):
IFG: FPG is 100 mg/dl to 125 mg/dl
IGT: plasma glucose is 140 mg/dl to 199 mg/dl at 2 hours during an OGTT
Recent research has shown that some long-term damage to the body, especially the heart and circulatory system, may already be occurring during pre-diabetes. Research has also shown that if you take action to manage your blood glucose when you have pre-diabetes, you can delay or prevent type 2 diabetes from ever developing. Much of the same advice for good nutrition and physical activity that is given to patients who have diabetes can benefit people with pre-diabetes.

So, a long reply. I don't mean to scare
