My wife is experiencing some low blood pressure symptoms, but seems to have near normal pressure. She feels some tiredness and flu like spacey not normal condition. These are intermittent cycles that have been occurring over the past 6 months. She has had a physical within this time period, but received no specific treatment or explanation from her physician. I know low potassium can be one of many causes for this feeling. She has had some irritable bowel syndrome and got treatment. She is on a gluten free diet. But the above condition persists and interrupts normal daily activities. She is 68 and maintains an office work schedule.
