Hello, thanks for the query to H.C.M. Forum
Frankly I would like to say one thing that your's wife is a diabetic prone so whatever some one say please make sure regular check up of diabetes
for your wife and glucose
monitoring is necessary and it will booster her morale.
If any thing abnormal you can take treatment well in time so don't forget this thing.
Secondly your wife is pregnant so diet restriction is also very important and after consultation with a gynaecologist , diabetologist
move in right direction.
Mind it one thing ,if she have high sugar level than why worry take treatment.
If not high than than why worry, don't take treatment.
Light regular exercises only for pregnant patients are advised so consult a physiotherapist and have good life.
Good luck Dr. HET
