Low Blood Pressure

Hello, has anyone experienced a slight head rush when you get up from sitting? I’ve had them more this month. I’m ordering blood panels today. And I’m eating more protein and taking electrolytes, iron etc. I’m wondering if this might be gut related. I noticed as my weight dropped, there just isn’t as much action in that dept. Calories are about right. I’m following the standard for my weight.

I’m baffled. It’s not comfortable and I’m a little worried.
