Doctors have warned that changes in the feet can sometimes be early signs of serious illnesses such as diabetes, heart disease, and kidney disorders, stressing that foot care is not merely cosmetic but a key step in protecting overall health.
Experts explain that the feet contain a complex network of nerves and blood vessels, making any alteration a possible indicator of internal problems.
Warning signs include skin discoloration, numbness or tingling, wounds that don’t heal, hair loss on toes, and dark streaks under the toenails.
Diabetes is one of the main conditions affecting foot health, leading to nerve damage and poor circulation, while swollen feet may point to chronic kidney disease.
Red spots or dark lines beneath the nails can also signal endocarditis, an infection of the heart’s inner lining.
Doctors recommend checking your feet daily, watching for unusual changes, maintaining good hygiene, wearing comfortable shoes, and staying physically active to support healthy circulation.
