I'm in my 12th week and have recently been experiencing dizziness and hot flushes when I wake up in the morning and on the train to work. My doctor says my blood pressure is good so must be blood sugar but says it's normal and to just ensure I keep snacking and drinking water but I find that not much helps in the mornings. My heart starts racing and I feel very hot and light headed. Do I need to have a big cooked breakfast if snacking is not helping? I'm not big on eating lots for breakfast as I can't stomach much early in the morning, so I usually have a smoothie around 8:30 but have been starting my morning with whole grain toast as I'm so hungry when I wake up and I snack on pieces of apple and date balls on the train but I still get this feeling. Any other suggestions? Hate this feeling like I'm going to faint.
