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.

A congenital foot problem is a problem affecting the feet, toes, and/or ankle that a child is born with. Several issues with a child’s feet can occur congenitally. Such problems include clubfoot, vertical talus, tarsal coalition, polydactyly, macrodactyly, and cleft foot. Some of these problems have a genetic basis, with someone in their family history having a gene causing the condition, and some are simply an anomaly.

The following are specifics about a few of these conditions:

-    Clubfoot, also called congenital talipes equinovarus or talipes equinovarus, is When the tendons of the foot shorten, the bones are of an unusual shape, and the Achilles tendon is tight, causing an inward and downward pointing of the foot. The soles of the feet might also face each other. In most cases of clubfoot, both feet are affected. If not treated, the affected child will walk on the sides of their feet or ankles.

-    Polydactyly is a condition where the child has more than five fingers or toes on either or both feet. Presentation usually consists of a nubbin or small lump of tissue without a bone, a toe that is partially formed but has no joints, or an extra toe.

-    Vertical talus is where the talus bone forms in the wrong position, other bones in the foot do not line up properly, the front of the foot points up, and the bottom of the foot is stiff, has no arch, and usually curves out. This can occur in one or both feet and if left untreated, can lead to serious disability or discomfort as the child grows.

-    Tarsal coalition is when there is an abnormal connection of two or more bones in the foot leading to severe, rigid flatfoot. The tarsal bones, located toward the back of the foot and in the heel, are the ones affected. This condition is often present at birth, but signs of the disorder usually come on in early adolescence.

-    Cleft foot is a rare condition where the foot has missing toes, a V-shaped cleft, and other anatomical differences. Surgery can often help improve the foot’s function since the heel remains normal and is what is most needed for walking. The main issues with this affliction are whether the affected foot can fit into a shoe and the shape and appearance of the foot.

-    Macrodactyly is when the toes are abnormally large due to overgrowth of the underlying bone or soft tissue. Having this condition makes it harder for the child to use the affected foot for certain activities.

Diabetes can cause two problems that can potentially affect the feet: Diabetic neuropathy and Peripheral Vascular Disease. Diabetic neuropathy occurs when nerves in your legs and feet become damaged, which prevents you from feeling heat, cold, or pain. The problem with diabetic neuropathy is that a cut or sore on the foot may go unnoticed and the cut may eventually become infected. This condition is also a main cause of foot ulcers. Additionally, Peripheral vascular disease also affects blood flow in the body. Poor blood flow will cause sores and cuts to take longer to heal. Infections that don’t heal do to poor blood flow can potentially cause ulcers or gangrene.

There are certain foot problems that are more commonly found in people with diabetes such as Athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These conditions can lead to infection and serious complications such as amputation. Fortunately, proper foot care can help prevent these foot problems before they progress into more serious complications.       

Each day you should wash your feet in warm water with a mild soap. When you finish washing your feet, dry them carefully especially between your toes. You should also perform daily foot inspections to ensure you don’t have any redness, blisters, or calluses. Furthermore, if you are diabetic, you should always wear closed-toed shoes or slippers to protect your feet. Practicing these tips will help ensure that your feet are kept healthy and away from infection.

If you have diabetes, contact your podiatrist if you have any of the following symptoms on your feet: changes in skin color, corns or calluses, open sores that are slow to heal, unusual and persistent odor, or changes in skin temperature. Your podiatrist will do a thorough examination of your feet to help treat these problematic conditions.

Trauma to the foot, especially the toes, can occur in many ways. Banging them, stubbing them, or dropping something on them are a few different ways this trauma can occur. Given the fact that toes are positioned in front of the feet, they typically sustain the brunt of such trauma. When trauma occurs to a toe, the result can be a painful break or fracture. Another type of trauma that can break a toe is repeated activity that places stress on the toe for prolonged periods of time.

Broken toes can be categorized as either minor or severe fractures. Symptoms of minor toe fractures include throbbing pain, swelling, bruising on the skin and toenail, and the inability to move the toe with ease. Severe toe fractures require medical attention and are indicated when the broken toe appears crooked or disfigured, when there is tingling or numbness in the toe, or when there is an open, bleeding wound present on the toe.

Generally, a minor toe break will heal without long-term complications. However, it is important to discontinue activities that put pressure on the toe. It is best to stay off of the injured toe and immediately get a splint or cast to prevent any more additional movement of the toe bones. You can also immobilize your toe by placing a small cotton ball between the injured toe and the toe beside it. Then, tape the two toes together with medical tape. Swelling can be alleviated by placing an ice pack on the broken toe directly as well as elevating your feet above your head.

Severe toe fractures may be treated with a splint, cast, and in some cases, minor surgery, especially when the big toe has been broken. Due to its position and the pressure the big toe endures with daily activity, future complications can occur if it is not properly treated. Pain associated with minor toe fractures can be managed with over-the-counter pain medications. Prescription pain killers may be necessary for severe toe fractures.

The healing time for a broken toe is approximately four to six weeks. In severe cases where the toe becomes infected or requires surgery, healing time can take up to eight weeks or more. While complications associated with a broken toe are immediately apparent, it is important to note that there are rare cases when additional complications, such as osteoarthritis, can develop over time. You should immediately speak with your podiatrist if you think you have broken your toe due to trauma. They will be able to diagnose the injury and recommend the appropriate treatment options. 

Gout is a form of arthritis that is caused by a buildup of uric acid crystals in the joints. This considered to be one of the most frequently recorded medical illnesses throughout history. Gout occurrences in the US have risen within the past twenty years and the condition now affects 8.3 million people which is 4% of all Americans. Researchers have found that gout affects men more than women and African-American men more than white men. 

Symptoms of gout are warmth, swelling, discoloration, and tenderness in the affected joint area. The small joint on the big toe is the most common place for a gout attack to occur.

People who are obese, gain weight excessively, drink alcohol heavily, have high blood pressure, or have abnormal kidney function are more likely to develop gout. Furthermore, certain drugs and diseases are likely to increase levels of uric acid in the joints which eventually leads to gout. You are also more likely to develop gout if you eat a lot of meat and fish.

Many who experience gout attacks will experience repeated attacks over the years. Some people who have gout symptoms, may never have them again, but others may experience them several times a year. If you have gout symptoms throughout the year, you may have recurrent gout. Those who have gout should also be careful about their urate crystals collecting in their urinary tract, because this may lead to kidney stones.

Diagnosis for gout is done by checking the level of uric acid in the joints and blood. Your podiatrist may also prescribe medicine to reduce uric acid buildup in the blood, which will help prevent any gout attacks.

To treat gout, your podiatrist may also prescribe you Anti-inflammatory medication (NSAIDs) which will relieve the pain and swelling of a gout episode and it can also shorten a gout attack. Maintaining a healthy diet is also a proven method to prevent gout attacks.
