There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.

In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.

According to the American Diabetes Association (ADA), diabetes is a condition that affects approximately 23.6 million Americans.  Around 750,000 new cases are diagnosed each year, and the disease’s most common form, Type 2 diabetes, makes up for 90 to 95 percent of these cases.  Type 2 diabetes is especially prevalent among older Americans, those who are obese, and those who lead sedentary lifestyles.

Complications of the disease may lead to several foot and ankle-related conditions.  The loss of nerve sensation, or neuropathy, can cause diabetics to lose feeling at the bottom of the feet and therefore leave them unaware of pain, pressure, and heat.  Decreased circulation is another complication of diabetes that can slow down the healing of wounds and injuries; this can lead to the development of foot ulcers.

To prevent foot ulcers from forming, diabetics should examine their feet every day for small cuts and wear shoes that curtail pressure.  Constant monitoring for the risk factors associated with ulcer formation can allow for early detection and therefore lessen the possibility of ulcers or, even worse, amputation.  The removal of calluses and ingrown toenails should be left to the podiatrist to avoid improper removal and possible infection.

Diabetic patients may also experience foot deformities due to complications in their feet, such as limited joint mobility, muscle atrophy, and decreased fat padding.  These complications can increase pressure in certain areas of the foot, which in turn can cause certain deformities, such as hammertoe, to form.  Another deformity, Charcot foot, develops due to the collapsing of microfractures in the bones of the feet.  The resulting deformity is a foot that is flattened and wider in appearance.

To help minimize pressure and prevent the development of these diabetes-related foot and ankle conditions, your podiatrist may consider using orthotics or special shoes.  Charcot foot may be treated using walkers, custom orthotic insoles, or non-weight-bearing or rigid weight-bearing casts or braces.  In more serious cases, surgery may be considered to treat more developed deformities.  Ulcers can be further cared for with the help of proper diet, medication to control glucose, intensive wound care, and infection treatment.

Elderly Americans are very susceptible to falls as they get older. Everyone experiences decreases in flexibility, balance, strength, and the senses as they age. This correlates to some eye-opening statistics. 1 in 4 Americans aged 65 and older fall each year. An elderly American is being treated for a fall in an emergency room every 11 seconds. In light of these striking statistics, one can see the importance of taking steps to prevent falls.

Finding an exercise program for the elderly is an excellent way to reduce the likelihood of falls. Look for an exercise program that improves strength and balance. Elderly people who live a more sedentary lifestyle, with little physical activity, are at an increased risk of falling. Wearing well-fitted footwear that provides good foot support and cushion will help prevent falls from poorly fitted shoes. Talking to a podiatrist about your susceptibility to falls and about inspecting your prescriptions will help to avoid any medication that could make falls more likely. Due to a decline in the senses among the elderly, having your eyes and hearing checked is recommended.

Around half of all falls occur in the household. Removing tripping hazards in the home and making it more accommodating to older persons can significantly reduce falls. Some notable household changes include increasing lighting around the house, installing grab bars in the shower and bathroom, and making sure the floor is clear of clutter. Other smart options include installing a shower chair, using rubber-bottomed rugs, and placing railings on both sides of stairwells.  

Finally, discuss with a doctor and your family about your fear of falling. This will help to increase awareness among the population on the need for fall prevention. A lack of awareness on the matter, and a downplaying of importance are what increase the risks of falling. Following these tips can help to reduce the risk for yourself and your loved ones.

Heel spurs are the result of calcium deposits that cause bony protrusions on the underside of the heel. Heel spurs are usually painless, but they have the potential to cause heel pain. Heel spurs tend to be associated with plantar fasciitis, which is a condition that causes inflammation of the band of connective tissue that runs along the bottom of the foot. They most often occur to athletes whose sports involve a lot of running and jumping.

Some risk factors for developing heel spurs include running and jogging on hard surfaces, being obese, wearing poorly fitting shoes, or having walking gait abnormalities.

It is possible to have a heel spur without showing signs of any symptoms. However, if inflammation develops at the point of the spur’s formation, you may have pain while walking or running. In terms of diagnosis, sometimes all a doctor needs to know is that the patient is experiencing a sharp pain localized to the heel to diagnose a heel spur. Other times, an x-ray may be needed to confirm the presence of a heel spur.

Heel spurs can be prevented by wearing well-fitting shoes that have shock-absorbent soles. You should also be sure that you are choosing the right shoe for the activity you want to partake in; for example, do not wear walking shoes when you want to go on a run. Additionally, maintaining a healthy weight can be beneficial toward preventing heel spurs, as it will prevent an excess amount of pressure being placed on the ligaments.

There are a variety of treatment options for people with heel spurs. Some of these include stretching exercises, physical therapy, shoe inserts, or taping and strapping to rest stressed muscles and tendons. If you have heel pain that lasts longer than a month, don’t hesitate to seek help from a podiatrist. Your doctor can help you determine which treatment option is best for you.
