Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that can be onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.

Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.

Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.

Symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the material, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.

If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.

If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.

A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.

Bunions are large bony bumps at the base of the big toe. Medically known as hallux valgus, a bunion is a misalignment of the metatarsophalangeal joint, or big toe joint. The misalignment will generally worsen with time if left untreated.

The exact cause of bunions is unknown, with genetics seen as a potential cause. High heels and poorly-fitted footwear, rheumatoid arthritis, and heredity all seem to be potential factors behind the exacerbation of bunions. Women have been found to be more likely to develop bunions in comparison to men.

Bunions do not always produce symptoms. The best way to tell is if the big toe is pushing up against the next toe and there is a large protrusion at the base of the big toe. You may or may not feel pain. Redness, swelling, and restricted movement of the big toe may be present as well.

Podiatrists use a variety of methods to diagnose bunions. If there are symptoms present, podiatrists will first consider that it is a bunion. If not, a physical examination will be conducted to check function of the big toe. Finally, an X-ray may be taken to view the extent of the bunion and confirm it is a bunion.

Typically, nonsurgical methods are used to treat bunions, unless the bunion has become too misaligned. Orthotics, icing and resting the foot, roomier and better fitted shoes, taping the foot, and pain medication are usually utilized first. If the bunion doesn’t go away or causes extreme pain, surgery may be required. Surgeons will either remove part of the swollen tissue or bone to straighten the toe out.

If you have a bunion, it is recommended to see a podiatrist. The longer it is left untreated, the worse it may get. Podiatrists can properly diagnose and treat a bunion before it gets worse.

Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.

Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.

The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.

The branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.

To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.

When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.

Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.

Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.

Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.

When it comes to maintaining foot health, wearing properly-fitting shoes is important. While wearing the appropriate pair of shoes may seem like a trivial concern, the reality is that improperly fitted shoes cause an astounding amount of injuries to the feet. The overall structure and the biomechanics of our bodies are directly affected by our posture, gait, and feet. Because of this, pain and discomfort felt throughout the body are often related to a problem in the feet. And, most foot problems usually stem from improper footwear.

Shoes should not be purchased with the expectation that they will easily stretch and contort to the size and shape of your feet. When shopping for footwear, look for shoes that fit correctly and comfortably as soon as you put them on. Do not purchase shoes that are too large or that slip in the heel area when you walk. Do not choose shoes that are loose with the intention of wearing thicker socks to compensate for the space. The widest portion of the shoe, the ball of the foot, must be made sure to fit comfortably in the shoe. 

Keeping all of these suggestions in mind may be difficult when shopping and when trying to select from a wide array of different shoes. Nonetheless, your time and money will be wasted if you purchase a pair of shoes that are too uncomfortable for you to actually wear them. After finally selecting and purchasing a pair of shoes, try them on at home. To truly ensure whether or not your shoes fit comfortably with normal activity, walk around on a carpeted surface to determine how they feel on your feet.

The possibility of damaging your feet’s 33 joints, 26 bones, and 100+ ligaments is much higher than many people suspect. Finding an appropriate and properly-fitted pair of shoes is perhaps the single most important action you can take to maintain excellent foot health and help prevent injury. The fact that our feet continue to change with age is one that many people often forget. Even if our feet no longer change in size when we mature, our feet will still change in shape.

If you already have pre-existing foot problems, there is a greater possibility that wearing improperly-fitted shoes will worsen those problems. The good news, however, is that appropriate footwear is not difficult to find. While shopping for shoes, remember that improper footwear can detrimentally affect the feet, the entire body and its biomechanical structure as well. The shoes you wear can greatly impact your legs, back, and entire body, as your posture and gait are related to your feet. Finding and selecting the best properly-fitted shoes is necessary in achieving optimal health.
