Aiyo, high HB during pregnancy or postpartum kah? Either way, this one really need to follow up with your doctor or nurse, they'll tell you exactly what to do based on your situation, bcos sometimes it's just dehydration, sometimes need more investigation. A few of us mums went back for repeat checks kasi confirm, and the nurse or doctor will advise if you need to adjust anything like fluid intake or diet, don't try adjust sendiri! Let me know what your nurse say, but def don't ignore this one.
