What your feet can tell you about your health

Cramps
Everyone suffers from the occasional pain of cramp in the foot, but recurring symptoms can be a warning sign that you’re low on some vital minerals. The most likely culprits are calcium, magnesium and potassium, and the chance of suffering from a deficiency is higher in heavily pregnant women.
Concave nails
Toenails which curve or dent inwards like a spoon can be an indicator of iron deficiency, known as anaemia. Heavy periods and stomach ulcers are just two of the causes of anaemia, while other symptoms of the condition are cold feet and brittle nails.


Cold feet.
As well as anaemia, cold feet can point to more than a need to buy new socks. They may suggest a condition where the hormones produced by the thyroid gland aren’t at sufficient levels to regulate metabolism and temperature effectively. Known as hypothyroidism, this is particularly common in women over the age of 40.
Ulcers and Sores
Slow healing or recurring sores and ulcers on the feet are more than an unsightly annoyance. They can actually be a red flag warning of lethargic blood flow, caused by high levels of sugar that is a characteristic of diabetes.
A lack of blood flow will result in lower oxygen levels reaching the feet and minor injuries will not heal as they should. The problem is exacerbated by another symptom of diabetes, the reduced level of infection-fighting white blood cells.
Bumpy toes
Swollen toes with a noticeable bump at the tip should not be ignored, as they can be a warning sign of serious illness. Crohn’s disease, pulmonary fibrosis, lung disease, heart disease and lung cancer have all been noted to cause this odd aberration, so if you’re concerned, a visit to the doctor would be the best course of action.
Numbness
Peripheral neuropathy is common in those who suffer from diabetes or who abuse alcohol. The incorrect signals being sent to the feet by the damaged nerves of the peripheral nervous system result in numbness or an irritating pins and needles sensation.
