Diabetics have swollen feet as a result of infections that are secondary to a condition called diabetic neuropathy, reports WebMD. Diabetic neuropathy happens when high blood sugar levels lead to nerve damage. This damage causes numbness that makes feet prone to sores and subsequent infections and swelling. Patients experience no pain with blisters and injuries, and these problems progress to infections quickly. Diabetics may also have swollen feet as a side effect of diabetic medications, states MedicineNet.
Diabetic patients who have neuropathy should take special precautions to avoid injuries and infections, according to WebMD. Patients should wear shoes all the time and make sure shoes fit well. If feet are dry, it can help to use lotion to prevent sores and cracks. Physicians may sometimes recommend a patient see a podiatrist to care for toenails properly. Patients should also check their feet and legs for sores on a daily basis and consult a physician if feet are swollen.
Diabetics need to work with a doctor regularly to manage blood sugar and the resulting diabetic neuropathy, states WebMD. Symptoms of diabetic neuropathy improve with proper levels of blood sugar. These include tingling, pain, burning and the numbness that leads to injuries, infection and swelling.
