Does consuming caffeine cause less venous reflux to be found on an ultrasound?

Venous Reflux Exams . 6 answers . 11 months ago

Hello, I am interested in radiofrequency ablation of my greater saphenous veins. Last month an ultrasound showed continuous reflux at both greater saphenous junctions. I had no caffeine that day. I had another ultrasound today (after having 4 cups of coffee), and there was no reflux! Can consuming caffeine change the results of a person's reflux exam?

Caffeine will not appreciably affect venous reflux. However, menstrual cycles will aggravate reflux, as will exercise and heat. Finally, make sure your ultrasound is done while standing when testing for reflux; it may
not show up when lying flat.

I wouldn't attribute that to caffeine but other factors like weather and hydration. It could also be an error on behalf of the technician. Make sure you go see a certified physician with accreditation.

I am not aware that caffeine has a major effect on venous reflux. The ultrasound results can vary over time and are dependent on your hydration status and the technique used for the ultrasound. It is especially important for the ultrasound to be performed with the patient in the standing position. The sensitivity settings on the ultrasound unit can also affect the detection of reflux.

Can consuming caffeine change the results of a person's reflux exam? The answer is yes. Caffeine is a mild vasoconstrictor and venoconstrictor. It can have a small effect on a venous reflux exam. We advise no caffeine
before our reflux studies. That said, other factors may also be involved, such as the time of day the study was done, the temperature of the room, the position you were in, and the experience of the technologist.

I doubt that caffeine would have any impact. Dehydration, the temperature in the room, position (supine or standing), time of the day might have an impact.

Caffeine should have no affect on reflux. One of the venous reflux exams was wrong.

I've had two separate venous ultrasounds done at two different clinics. Neither showed much reflux, yet symptoms still persist.

Compression stockings seem to help some, but there are days where I am not sure. I have classic vein symptoms, such as pain in the calves and the back of the upper thigh.

I have to sit down and elevate my legs constantly, as it's hard to stand up.
