Things Your Feet Says About Your Health
A sore that won't heal on the bottom of the foot
What it means: This is a major clue to diabetes. Elevated blood glucose levels lead to nerve damage in the feet—which means that minor scrapes, cuts or irritations caused by pressure or friction often go unnoticed, especially by someone who's unaware he has the disease. Untreated, these ulcers can lead to infection, even amputation.
More clues: Oozing, foul-smelling cuts are especially suspect because they've probably been there awhile. Other symptoms of diabetes include persistent thirst, frequent urination, increased fatigue, blurry vision, extreme hunger and weight loss.
What to do: Get the ulcer treated immediately and see a doctor for a diabetes evaluation. Diabetics need to inspect their feet daily (older people or the obese should have someone do this for them) and see a healthcare professional every three months.
Cold feet
What it means: Women, especially, report cold feet (or more precisely, their bedmates complain about them). It may be nothing—or it may indicate a thyroid issue. Women have a slightly lower core body temperature than men, which makes them more vulnerable to being cold even when they're perfectly healthy. Women over 40 who have cold feet often have an underfunctioning thyroid, the gland that regulates temperature and metabolism. Poor circulation (in either gender) is another possible cause.
More clues:Hypothyroidism's symptoms are pretty subtle and appear in many disorders (fatigue, depression, weight gain, dry skin).
What to do: Insulating layers of natural materials work best for warmth. (Think wool socks and lined boots). If you also have other nagging health complaints, mention the cold feet to your doctor. Unfortunately, however, aside from treatment with medication in the event of a thyroid condition, this tends to be a symptom that's neither easily nor sexily resolved.
Thick, yellow, downright ugly toenails
What it means: A fungal infection is running rampant below the surface of the nail. Onychomycosis can persist painlessly for years. By the time it's visibly unattractive, the infection is advanced and can spread to all toenails and even fingernails.
More clues: The nails may also smell bad and turn dark. People most vulnerable: those with diabetes, circulatory trouble or immune-deficiency disorders (like rheumatoid arthritis). If an older person has trouble walking, sometimes the problem can be traced to the simple fact that as infected nails grow thicker, they're harder to cut and simply go ignored to the point of pain.
What to do: See a foot specialist or your regular physician for care and treatment. In serious cases, over-the-counter antifungals are usually not as effective as a combination of topical and oral medications and the professional removal of diseased bits. Newer-generation oral antifungal medications tend to have fewer side effects than older ones.
A suddenly enlarged, scary-looking big toe
What it means: Probably gout. Yes, that old-fashioned-sounding disease is still very much around—and you don't have to be over 65 to get it. Gout is a form of arthritis (also called "gouty arthritis") that's usually caused by too much uric acid, a natural substance. The built-up uric acid forms needlelike crystals, especially at low body temperatures. And the coolest part of the body, farthest from the heart, happens to be the big toe.
"Three-fourths of the time, you wake up with a red-hot swollen toe joint as the first presentation of gout," says podiatrist Andersen.
More clues: Swelling and shiny red or purplish skin—along with a sensation of heat and pain—can also occur in the instep, the Achilles tendon, the knees and the elbows. Anyone can develop gout, though men in their 40s and 50s are especially prone. Women with gout tend to be postmenopausal.
