Get dizzy and light headed when I cough. Feel like passing

Customer Question

get dizzy and light headed when I cough. Feel like passing out. Why?
JA: How long have you been dealing with the cough? Are you having any other symptoms?
Customer: I have a lot of unanswered medical issues. But recently have been coughing and immediately heart flutters and things get dark and light headed feeling starts. Once coughing episode is done blood flows and ok but confused as to why.
JA: Anything else in your medical history you think the doctor should know?
Customer: broke right tibia last year, it healed but can't use right foot. swells from 29cm to 34cm by night time and leg is swollen with pitting. Possible blockage or nerve damage I assume. Have not been able to have no sensations like tingling, burning, pressure and feels like walking on we sponge inside foot. Make sense?

Hello again,
I was waiting for your reply.
What you are experiencing is probably cough syncope.
In some cases due to coughing or sneezing there is less venous blood return to heart & the cardiac output or blood coming from heart is diminished.
There is also an increase in vagus nerve tone.
All these effects causes less blood supply to brain producing syncope
I feel you can take a consultation with a cardiologist.
You need to be careful during coughing & avoid doing it forcefully.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
