But when these valves don't work well, blood can also flow backwards. Stress (from losing a bonded mate, a change in environment, etc.) Duplex ultrasound is the most commonly used investigative technique as it can recognize venous reflux when clinical diagnosis is uncertain. People living with diabetes are prone to having foot problems, often because of two complications of diabetes: nerve damage (neuropathy) and poor circulation.

When malfunctioning vein valves are left untreated, and as it progresses, venous stasis can cause increasing pain and swelling in affected areas while also increasing the risk of blood clots and contributing to the formation of varicose veins, venous stasis ulcers .

This causes them to relax • Acute adrenal insufficiency (Distributive (vasodilation) (24) resulting in a sudden decrease shock) is frequently the result of discontinuing in blood pressure (secondary to a decrease in corticosteroid treatment without tapering the peripheral vascular resistance).Neurogenic shock dosage. The condition most often occurs when there's insufficient blood flow and decreased circulation to the veins in one or both of the legs. Definition, rationale and scope. Dermatologists and other doctors continue to study why only certain people develop stasis dermatitis. This leads to gathering of fluid in the lower half of your legs.
