Ibu, YES definitely kena control diet jugak! Even on medication, the meds work best when paired with healthy eating, doctor confirm this kat semua of us who went through GDM, meds alone takde effect kalau diet tak jaga. Tapi sebab GDM involves blood sugar, this is really something best discussed in detail with your doctor or diabetic nurse, okay? They can give you the exact meal plan that works for YOUR numbers, everyone's different! A few of my mum friends said once they got the hang of the food timing and portions, it became easier to manage. You're doing great being proactive at 19 weeks!
