What Can Our Feet Tell Us About the Rest of Our Boday?

Can you pick up conditions and diseases, throughout the body, just by looking at someone’s feet?

Our feet are remarkable structures that not only support us in our daily activities but also provide valuable insights into our overall health. Beyond the realm of foot-specific ailments, certain symptoms in the feet can serve as early indicators of systemic conditions affecting the rest of the body.

In this blog, we will explore how paying attention to foot symptoms can help identify and address various conditions that extend beyond the feet.

1. Diabetes:

Diabetes is a metabolic disorder that affects multiple systems in the body. The feet are particularly susceptible to complications related to diabetes, such as peripheral neuropathy (nerve damage) and peripheral vascular disease (poor circulation). Symptoms to watch out for include numbness, tingling, foot ulcers, slow wound healing, and changes in skin colour or temperature. Detecting these symptoms early can prompt timely intervention and prevent serious complications.

2. Arthritis:

Arthritis encompasses a group of conditions characterised by joint inflammation and pain. While arthritis commonly affects the hands, wrists, and knees, it can also manifest in the feet. Symptoms such as joint stiffness, swelling, and difficulty walking or bearing weight may be indicative of arthritis. Early recognition of these symptoms allows for appropriate management and preservation of joint function.

3. Cardiovascular Disease:

The health of our cardiovascular system can be reflected in the feet. Peripheral arterial disease (PAD), a condition that narrows or blocks the arteries supplying blood to the extremities, often manifests as pain or cramping in the legs or feet during physical activity. Changes in the colour, temperature, or texture of the feet, as well as slow wound healing, may also be signs of compromised blood flow. Identifying these foot symptoms can prompt further evaluation and help manage cardiovascular health.

4. Kidney Disease:

Kidney disease can impact multiple systems in the body, including the feet. Edema, or swelling, in the lower extremities is a common symptom of kidney dysfunction. Swollen feet and ankles, often accompanied by puffiness or tightness in the skin, may indicate fluid retention and impaired kidney function. Recognizing these foot symptoms can prompt individuals to seek medical attention and facilitate early detection of kidney disease.

5. Thyroid Disorders:

The thyroid gland regulates metabolism and plays a crucial role in overall health. Both an overactive thyroid (hyperthyroidism) and an underactive thyroid (hypothyroidism) can lead to foot-related symptoms. Hyperthyroidism may cause excessive sweating, warm and moist feet, and skin thinning. On the other hand, hypothyroidism can result in dry, coarse skin, cold feet, and swelling. Paying attention to these foot symptoms can contribute to the identification and management of thyroid disorders.

6. Nerve Disorders:

Various nerve disorders can impact the feet, often causing sensory disturbances and pain. For example, peripheral neuropathy, commonly associated with conditions like diabetes, can result in tingling, numbness, or a “pins and needles” sensation in the feet. Additionally, conditions such as multiple sclerosis and spinal cord injuries can also cause foot-related symptoms. Recognizing these manifestations in the feet can aid in diagnosing and managing nerve disorders.

As a podiatrist, seeing a patient’s feet can serve as a gateway to understanding the overall health of a patient’s body. By paying attention to foot symptoms and changes, we can gain valuable insights into various systemic conditions affecting different organs and systems. Early recognition and intervention based on foot-related signs can help with timely diagnosis and treatment, potentially preventing further complications and improving overall well-being. Patients are often amazed by what I can pick up on, just by looking at their feet….and often extremely thankful if it means an early diagnosis!
