Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Swelling in the legs after prolonged standing is caused by the mechanism that liquid part of the blood comes out the vessels (veins) and accumulated in the surrounding tissues. It is called
peripheral edema.
Variety of conditions may lead to peripheral edema. It could be heart problems, venous deficiency,
liver or
kidney problems or the side effect of certain medications. I would like to ask the following questions which may aid to clarify the cause of her peripheral edema.
Does she have visible purple veins under the skin of her legs? Does she have any other health problems (heart, liver, kidney diseases, and
high blood pressure)? Does she take any medications? Has she had any trauma or surgery (especially in the lower extremities) in the past?
She may get the benefit of wearing elastic compression stockings, elevating leg with the pillow while on a bed, not sitting/standing long time which helps to prevent fluid buildup in the legs.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Malik Amonov
