Hi,thanks for query.The best option is to get in touch with hormone specialist.As you are not taking any steroid or anti asthmatics,drugs increasing your sugar is not the issue at present.Yes,steroids
do can make your face looking puffy,but this is once you stop the treatment you become fine.Again for asthma you must had steroids in inhalation form and from doctor,so steroid leading to diabetes
does not seems to acceptable.You endocrinologist
may ask for some additional test like c peptide level,which measures insulin
secretion in body and other test as per the need and will clarify your doubts.
wishing you good health.
