Itchy soles of the feet are related to diabetes. Itching on the soles of the feet may be caused by poorly controlled blood sugar in diabetic patients, causing peripheral neuritis. It is advisable to go to a regular tertiary care hospital in a timely manner to clarify the blood sugar level, and if it is determined to be caused by diabetes, targeted treatment measures should be taken under the guidance of a specialist, and attention should be paid to dietary regimen in general.
