Hypotension 低血壓

Last Monday, I was diagnosed as low blood pressure at 52 which result me feel dizzying all the time if I stand. So, I was off work for days. The Doctor said it may be caused by hungry. Maybe yes. I do feel hungry almost from morning at 10 to off work at 5pm. I don't like to eat British cold lunch in office, so I nearly eat nothing at lunch for two months. Now, I must change this bad habit for my husband. I don't know what to do with the low blood pressure. just feel down. Since last week, I have dizzying everyday and have to lay in bed in order to help my brain has enough blood and Oxygen. Hopefully, everything is fine for me soon.
