Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat.  In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.

People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.

The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic.  Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.

If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day.  You may even need to wash your feet twice a day, if necessary.  You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt.  In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.

Untreated hyperhidrosis can easily lead to complications.  Some complications that may arise from the disorder include nail infections, warts, and bacterial infections.  Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.

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.

Athlete’s foot is a type of fungal infection that affects the skin on the feet. It is caused when the tinea fungus grows on the foot. It is possible to catch the fungus through direct contact with someone who has it or by touching a surface that is contaminated with it. This type of fungus thrives in warm, moist environments such as showers, locker room floors, and swimming pools. Your risk of getting it may also increase by wearing tight-fitting, closed-toe shoes, or by having sweaty feet.

Symptoms of athlete’s foot include itching, stinging or burning sensations between the toes. You may also experience toenails that are discolored, thick, crumbly, or toenails that pull away from the nail bed.

Your podiatrist may diagnose athlete’s foot by detecting these symptoms or by doing a skin test to see if there is a fungal infection present. The most common exam used to detect Athlete’s foot is a skin lesion potassium hydroxide exam. To use this method, your doctor will scrape off a small area of the infected skin and place it into potassium hydroxide. The potassium hydroxide will destroy the normal cells and leave the fungal cells untouched so that they are visible under a microscope.

There are a variety of treatment options for athlete’s foot. Some medications are miconazole (Desenex), terbinafine (Lamisil AT), clotrimazole (Lotrimin AF), butenafine (Lotrimin Ultra), and tolnaftate (Tinactin). While these options may be able to treat your fungus, it is best that you consult with a podiatrist in order to see which treatment option may work best for you.

In some cases, Athlete’s foot may lead to complications. A severe complication would be a secondary bacterial infection which may cause your foot to become swollen, painful, and hot.

There are ways that you can prevent athlete’s foot. Washing your feet with soap and water each day and drying them thoroughly is an effective way to prevent infections. You also shouldn’t share socks, shoes, or towels with other people. It is crucial that you wear shower sandals in public showers, around swimming pools, and in other public places. Additionally, you should make sure you wear shoes that can breathe and change your socks when your feet become sweaty. If you suspect that you have Athlete’s foot, you should seek help from a podiatrist as soon as possible.

Many foot diseases and conditions become more serious and common among the elderly. Some of these conditions include diabetic ulcers, ingrown toenails, fungus, arthritis, corns, and calluses. Unfortunately, it may be harder for older adults to take care of their own feet, but there are some precautions they can take in order to avoid any serious conditions.

Dry, cracked heels tend to be a common problem for older people. In order to avoid this, you should always keep your feet clean and well moisturized. Special feet moisturizers should be used as average lotions might not provide enough moisture for dry and cracked heels. Daily foot inspections are crucial for the elderly to detect any irregularities in their earliest stages. During the aging process, blood circulation tends to slow down causing older people to not feel their feet as well as they used to. This often results in foot problems going unnoticed.

Fungal and bacterial conditions thrive on elderly feet because older adults are less likely to keep their feet clean and dry; this makes it easier for bacteria to take hold in their dry, cracked skin. Elderly people should be sure to thoroughly dry their feet, especially in between the toes, after bathing. This will help them avoid developing any fungal infections. Additionally, clean cotton socks should be worn after the feet are dried.

Cutting toenails straight across will help prevent ingrown toenails. When toenails are cut too lose, the nail might break through the skin resulting in an ingrown nail. Clippers should be used to cut the nails in order to make the cut even.

Elderly people who have diabetes are at risk of developing serious foot problems that may lead to amputation. Ulcers that are left untreated can lead to gangrene. Dry and cracked feet, fungus, and untended cuts under the nails may also lead to infections.

Fortunately, Medicare covers many different types of services for foot care. Elderly people with any of these foot conditions should seek the help of a podiatrist and perform daily foot inspections in order to ensure that they have healthy feet.

Sesamoiditis is a condition in which the sesamoid bones in the forefoot become inflamed from physical activity. Sesamoid bones are bones that are not connected to other bones but are located in tendons or muscle. Two of these sesamoid bones are very small and located on the underside of the foot near the big toe. Athletes such as runners, baseball and football players, and dancers are likely to experience sesamoiditis. Those with high arched feet, flat feet, or runners who run on the ball of their foot are also prone to suffer from sesamoiditis.

Symptoms include pain or throbbing on the ball of the foot near the big toe. The pain generally starts with a mild throbbing but gradually builds up to shooting pain. Bruising, swelling, and redness are possible, but in most cases, these symptoms are not present. However, moving the big toe can result in pain and difficulty.

To conduct a diagnosis, the podiatrist will examine the ball of the foot and big toe. They will look for any outliers and check the movement of the toe. X-rays will be taken to rule out any other conditions and ensure that it is sesamoiditis.

Treatment for sesamoiditis is generally mild and includes rest, anti-inflammatory and pain medication, and ice treatments to deal with the swelling and pain. Orthotics may be needed with people who have flat or high arched feet to relieve pressure off the bones. In some cases the toe will be taped and immobilized to allow healing. The podiatrist may also decide to use a steroid injection to help with swelling as well. If you have sesamoiditis, you shouldn’t engage in any intensive activity, as it may inflame the area and worsen your pain. If the sesamoid bone has fractured, surgery may be required to remove the sesamoid bone.

If you are suffering from sesamoiditis or are experiencing symptoms similar to sesamoiditis, you should stop all physical activity that puts strain on the area. Furthermore you should see a podiatrist for a diagnosis to see if you have sesamoiditis.
