Before you are told a battery of different tests one after another just to keep you busy forever get following done if you yourself suspect anything:
(7) C reative protien
(8) Lipid Profile
maybe tests for pancreas
islets working etc etc.
Then go to a doctor with these reports. Without these tests doctors today are clueless on everything. Perhaps add urine tests, stool tests also to above list. Perhaps something to test your liver
and kidneys too.
Since you are susceptible, ban all junk food, engineered oils and fats, coke, pepsi, miranda crap (all processed craps which pump in fructose in your body) and move towards alkaline diet.
