Why circulation testing matters in diabetes
Diabetes can reduce sensation and blood flow. A small blister or wound may become serious when circulation is poor. Vascular assessment helps identify arterial disease and guide referral or treatment planning.
Tests that may be used
Assessment may combine foot-pulse examination, pedal Doppler waveforms, ABI, toe pressure or TBI, and arterial duplex when anatomy needs to be mapped. In diabetes or chronic kidney disease, calcified arteries can make ABI falsely high or difficult to interpret, so no single test excludes arterial disease in every patient.
The clinical question guides the test
Testing may help answer whether peripheral artery disease is present, whether perfusion is likely to support wound healing, and whether urgent vascular imaging or referral is needed. Duplex maps arterial anatomy when that information will affect the next decision; it is not an automatic yearly scan for every person with diabetes.
Urgent diabetic-foot warning signs
Black tissue, spreading redness, pus, fever, severe rest pain, or a foot that suddenly becomes cold and painful needs urgent assessment. Sudden severe symptoms can be an emergency; call 112 in Kuwait. Ongoing care may involve the treating clinician, a diabetic-foot or wound team, and vascular specialists.
