President Donald Trump underwent medical testing after he had been seen with deep bruises on his hand and swollen legs in recent days, and was diagnosed with chronic venous insufficiency, White House press secretary Karoline Leavitt said Thursday.

Leavitt said Trump noted “mild swelling in his lower legs,” which prompted the White House medical team to evaluate him. They concluded that Trump has chronic venous insufficiency — a condition in which there isn’t adequate blood flow in the veins in the legs. This can cause the blood to pool, causing swelling in the lower legs.

“The president underwent a comprehensive examination including diagnostic vascular studies, bilateral lower extremity intravenous doppler ultrasounds were performed and revealed chronic venous insufficiency, a benign and common condition, particularly in individuals over the age of 70,” Leavitt said in the Thursday White House press briefing.

While chronic venous insufficiency is not considered a serious medical condition and it is treatable, it can be uncomfortable or painful. The condition is very common in older adults. Treatment typically can include medication to increase blood flow, elevating legs, or minor procedures to improve blood flow, or surgery in more severe cases.
