bromidrosis and hyperhidrosis



WHAT IS FOOT ODOR



Bromidrosis is the medical term for foot odor which is a foul smelling perspiration. This occurs when normally odorless foot perspiration becomes overgrown with decomposing bacteria, thus producing a pungent biochemical waste.

No one bacterial species is responsible for the odor with many of the resident (normally occurring on the skin) bacteria capable of producing volatile acids. Isobutyric acid produces a “dirty sock” odor while isovaleric acid produces the “smelly feet” odor. It has been found that athletes foot actually increases the bacteria count and thus worsen the foot odor.

Hyperhidrosis It is estimated that each foot contains over 250,000 sweat glands making the feet the highest concentration for this type of gland. It is this excessive perspiration that leads to foot odor. Excessive perspiration is known as hyperhidrosis. Excessive perspiration of the soles and usually the palms as well affects about one quarter of one percent of the population.

The more common type of hyperhidrosis is idiopathic (unknown origin) which is usually from excessive stimulation of the eccrine or sweat glands. This is a sympathetic nerve response along the lines of “fight or flight”, seen in nervous individuals, again leading to foot odor.

The other type of hyperhidrosis is the pathologic form, which may be the result of diabetes, hyperthyroidism, or even a lesion of the central or peripheral nervous system.

Hyperhidrosis clinically appears as pink moist skin that is cool to touch. The foot is also clammy. Excessive perspiration between the toes results in maceration. Sometimes the hyperhidrosis can be so severe that drops of sweat actually run off the foot; I have seen this a number of times over the years. Along with this the shoes are usually damp, and moldy. It is this type of environment that leads to foot odor.

TREATMENT OF FOOT ODOR



Management of both foot odor and perspiration go hand in hand. The easiest way to reduce odor is to reduce perspiration.

There are things to do to reduce the odor if you are having difficulty reducing the perspiration. Reducing odor tips include:

  • Boil a few tea bags in a pint of water for 15 minutes, then pour the water into a foot bath of two quarts of cool water. Soak your feet in this solution for 10-15 minutes. It is thought the tannic acid in tea is the odor neutralizer.
  • Simply washing your feet with soap and water each time you bathe. You would be surprised how many people step into a shower and never actually physically wash their feet.
  • There are numerous over the counter sprays and powders that will reduce foot odor.

The next thing is to reduce the amount of perspiration. Reducing perspiration tips include:

  • In patients where there is a nervous component, if the condition is bad enough, oral anti-anxiety medication may be indicated. You might be wondering why someone would take that kind of medication for sweaty feet; the answer is simple. This type of foot condition, producing foot odor, many times will lead to a secondary fungal infection, which may then lead to a bacterial infection of the foot. Depending on the overall health of the patient, bacterial infections of the foot can be very dangerous.

    Additionally, people with a severe case of hyperhidrosis can be affected psychologically. They are essentially embarrassed to be in any situation where they might have to take off their shoes and socks.

  • Change your shoes daily so that yesterday's pair has time to dry out.

    A mistake many people make is that they come home, take off their sweaty shoes and throw them into the dark, cool closet. Bacteria and fungus thrive in dark moist environments. The inside of the shoe never has a chance to dry out and the following morning is put back on the foot, further aggravating foot odor. A better idea is to leave the shoe by an open window or on a door stoop in order for the inside of the shoe to fully dry out.

  • Never wear shoes without socks. This just increases the amount of perspiration.
  • Cotton socks which are absorbent, fungistatic and bacteriostatic are a better choice than wool or synthetic socks which retain moisture.

    Look for socks which are impregnated with silver as silver has antibacterial properties. If it is possible, changing your socks midday is also recommended.

  • Substituting shoes and sandals instead of boots, if possible, is also a good idea.
  • Absorbent powder like Zeasorb are useful during the day. Baby powder is not as good.
  • Lotions like Bromilotion (Gordon labs), applied in the morning can be helpful.
  • 10% formaldehyde lotions which really dry out skin, but this medication has to be used sparingly.
  • Charcoal activated innersoles absorb perspiration and can be very helpful.




Believe it or not but there are topical antiperspirants for the feet. Ostiderm Roll-On is one such product. This product is applied twice a day for a week, then once daily and then perhaps every couple of days to keep the feet dry. Depending on how much your feet perspire you may have to experiment with the medication to find a regimen works best for you. Be careful not to over use the product as it will over dry your skin which should also be avoided.

Botox In recent years Botox (botulinum toxin type A) injections have become popular in diminishing perspiration in the feet and hands. The success rate is extremely high but there are a few potential adverse reactions including pain on injection, bruising, with muscle weakness being the main adverse reaction as a reaction to nerve blocks.

Since the treatment involves multiple injections with each injection occurring less than an inch apart, the total amount of injections will ultimately be determined by the size of the foot, thus it is best to have these injections done under anesthesia either intravenous sedation or via local anesthesia around the ankle which will completely numb the bottom of the foot. Each injection is limited to just underneath the skin. If the injections are done too deeply it can cause muscle weakness on the bottom of the foot.

There are contraindications for this type of treatment which include people with peripheral neuro-muscular disease, those with a hypersenitivity to Botox and women who are pregnant.

Once the perspiration is under control the next step is to reduce the bacterial and fungal population of the feet. This is accomplished by using a topical soap that has both anti-bacterial and anti-fungal properties.

Other outside factors tend to promote foot perspiration. Caffeine in coffee, tea and soda stimulates the sympathetic nervous system and thus produces more perspiration. Additionally, many patients are just anxious, nervous individuals causing excessive perspiration. Along with oral medication as mentioned earlier, stress reduction and relaxation techniques may be helpful.

Warts also have a tendency to spread more rapidly in excessively moist skin.

Dear Dr. Mitnick, The orthotics arrived four days ago and I slipped them into my shoes immediately. I was skeptical as to the usefulness of the item, they really didn't look very exotic. I have to say though, after using them for just four days, I have experienced grand relief from my foot pain. Even the very first day, I was able to do a lot of work while on my feet with at least a 75% reduction of pain. It has only gotten better every day, and I go nowhere without my shoes with the orthotics. I had been experiencing extreme heel and sole pain for about six months and had to take extended breaks off my feet many times a day as well as regular doses of Ibuprofen. Since getting the orthotics, my life has returned to normal and I feel good again. Just wanted to say thanks for the recommendation for a very effective item, I had no idea what a change this item could affect.

Yours truly,

Dr. Mitnick, Thank you, you were 100% correct. The pain finally brought me to the ER. I spent 8 days in the hospital. The Doppler you spoke of was able to show that there was no pulse in that foot. This was an arterial clot that split and traveled throughout my leg. My leg was almost amputated. I am in rough shape but have all my parts intact!! You certainly know what you are talking about. Thank you for taking the time to answer. Yours Truly!

Dr. Mitnick, Just want to say thank you so very much for your quick response and very informative reply! After reading what you had to say, I called the doctor's office and was able to get in and see him the same day as my injury. Toe was x-rayed and luckily, it is not broken or fractured. Very badly bruised and will probably lose the toe nail. And although my toe and toe nail are still very black and blue and very sore, they ARE both starting to feel a little better. So again, thank you! I am so very happy that I came across your website. The service you provide is outstanding and immeasurable!

Again, I really appreciate that you responded to my inquiry, and that your mention of Parkinson's helped me to find my way to a diagnosis of this difficult to diagnose disease. Most patients see on average 16 doctors before they are diagnosed. I hope that you can help other people that ask for your expertise in the future.
