I had GD in my second trimester and it was stressful, so I feel you. Please don't try self-treatment; follow exactly what your doctor and dietitian say because every body reacts differently. For me, cutting down heavy carbs and eating high-protein snacks like paneer or boiled eggs under my doctor's guidance worked wonders.
You need to be very strict with your diet now and absolutely check with your gynac first. Cut out processed sugar and white rice immediately, and start tracking your blood sugar after meals as advised by your doctor. A brisk 15-minute walk after lunch and dinner helped me keep things in control.
High blood sugar during pregnancy needs proper medical monitoring to avoid any complications for the baby. Make sure you don't skip your doctor appointments and keep a small digital glucometer at home to log your readings. Focus on complex carbs and keep your doctor updated on any spikes.
High sugar can be scary but it is totally manageable with some simple changes. Instead of normal roti, switch to multigrain or oats roti and eat smaller, frequent meals. But please consult your doctor immediately so they can plan a proper diet chart for you.
Getting a high sugar report can make your anxiety skyrocket, I remember crying so much when mine came back high. Please take a deep breath, this is very common and treatable. Just book an appointment with your gynac soon to manage it safely, don't worry.
