I no longer recommend ADA [American Diabetes Association] as ADA receives major funding from drug/pharmaceuticals companies.
Many thanks for the information that helps a lot.
I had been looking for that kind of information but could not find until now.
It's good to see that you are trying to manage your glucose levels b4 they get out of control.
An OGTT requires you to be sedentary 2 hours post test. Being active 1 hour post defeated your "homemade" test. See this link http://en.wikipedia.org/wiki/Glucose_tolerance_test
Q: "What can be the normal glucose level after 3-4 hours lunch or dinner time"
A: Glucose peaks 2-3 hours after meals where the normal value is <180 mg/dl and the optimum is <140 mg/dl. Four hours you should be at or close to normal levels.
Q: "If i make daily activity is it normal to have lower values?
If i make exercise , can this lower my glucose level."
A: Appears these are the same question on activity worded differently. Yes, daily exercise helps to lower your glucose.
Q: "I learned that during exercise insulin is generated and that can lower my gluce level rapidly."
A: See this link http://www.faqs.org/faqs/diabetes/faq/part1/section-15.html
Q: "Now i bougt a glucose meter, maybe it is better to make my own test at home while i am sitting."
A: Read and understand the instructions that came with the meter. Or, Google the make and model number for a user guide. Its important that you understand how to use the meter correctly or you will get false positive readings.
