Bromodosis (nieprzyjemny zapach stóp)
Etiologia i przyczyny

Bromodosis, czyli nieprzyjemny zapach stóp, wynika głównie z interakcji między potem a bakteriami skóry stóp. Stopy zawierają około 250 000 gruczołów potowych, które mogą produkować do filiżanki potu dziennie. Pot sam w sobie jest bezwonny, jednak w zamkniętym obuwiu sprzyja rozwojowi bakterii, które rozkładają pot i martwe komórki skóry, wytwarzając lotne kwasy organiczne, takie jak kwas izowalerinowy, propionowy, masłowy, octowy i walerianowy. Szczególnie istotne są bakterie Kyetococcus sedentarius (10-15% populacji, zapach zgniłych jaj), Brevibacterium, Staphylococcus epidermidis, Propionibacterium, Bacillus subtilis oraz Corynebacterium. Grzybica stóp (tinea pedis) również przyczynia się do bromodosis, tworząc środowisko sprzyjające bakteriom. Nadmierna potliwość (hyperhidrosis), w tym plantar hyperhidrosis, oraz czynniki hormonalne (okres dojrzewania, ciąża, menopauza), stres i niektóre leki mogą nasilać objawy.

Bromodosis (nieprzyjemny zapach stóp) – Etiologia

Bromodosis, medyczne określenie nieprzyjemnego zapachu stóp, to powszechny problem zdrowotny, który może powodować znaczny dyskomfort i zażenowanie społeczne. Główną przyczyną nieprzyjemnego zapachu stóp jest interakcja między potem a bakteriami znajdującymi się na skórze stóp. Istnieje wiele czynników, które mogą przyczyniać się do rozwoju tego schorzenia.123

Pot i bakterie jako główna przyczyna

Stopy mają wyjątkowo dużą liczbę gruczołów potowych – około 250 000 na każdej stopie – które mogą wytwarzać nawet filiżankę potu dziennie. Sam pot nie ma zapachu, jednak kiedy zostaje uwięziony w butach lub skarpetkach, stwarza idealne środowisko dla rozwoju bakterii. Bakterie żywiące się potem uwalniają kwasy, które powodują nieprzyjemny zapach.123

Bakterie naturalnie występujące na skórze stóp żywią się potem, obumarłymi komórkami skóry i wydzieliną gruczołów łojowych. W procesie rozkładu tych substancji bakterie wytwarzają lotne kwasy organiczne, które są źródłem nieprzyjemnego zapachu. Najczęściej wymieniane kwasy to:123

  • Kwas izowalerinowy (zapach podobny do sera)
  • Kwas propionowy (zapach podobny do octu)
  • Kwas masłowy
  • Kwas octowy
  • Kwas walerianowy

12

Specyficzne gatunki bakterii powodujące nieprzyjemny zapach

Kilka konkretnych gatunków bakterii jest szczególnie odpowiedzialnych za nieprzyjemny zapach stóp:123

  • Kyetococcus sedentarius – u około 10-15% populacji występuje ta bakteria, która wytwarza związki siarkowe nadające stopom zapach podobny do zgniłych jaj. Osoby posiadające tę bakterię mają zwykle wyjątkowo intensywny zapach stóp.
  • Brevibacterium – bakteria preferująca żyć i rozwijać się między palcami stóp. Lubi słony pot i wilgotne środowisko, co zapewnia idealne warunki do rozmnażania. Te same bakterie są odpowiedzialne za zapach serów typu Limburger.
  • Staphylococcus epidermidis – bakteria rozkładająca aminokwas leucynę obecny w pocie, produkując kwas izowalerinowy o intensywnym zapachu.
  • Propionibacterium – bakteria rozkładająca pot i wytwarzająca kwas propionowy o kwaśnym zapachu podobnym do octu.
  • Bacillus subtilis – związany z nasilonym zapachem stóp.
  • Corynebacterium – przyczynia się do powstawania nieprzyjemnego zapachu.

12345

Infekcje grzybicze

Grzyby mogą również przyczyniać się do powstawania nieprzyjemnego zapachu stóp. Podobnie jak bakterie, grzyby uwielbiają ciepłe, wilgotne środowisko, jakie zapewniają spocone stopy zamknięte w butach. Grzybica stóp (tinea pedis), powszechnie znana jako „stopa atlety”, jest częstą infekcją grzybiczą, która może powodować nieprzyjemny zapach, swędzenie i pieczenie.123

Grzybica może powodować suchą, łuszczącą się skórę, która stanowi doskonałą pożywkę dla bakterii. To połączenie grzybów i bakterii może prowadzić do wyjątkowo nieprzyjemnego zapachu stóp.12

Czynniki predysponujące do bromodosis

Nadmierna potliwość (hyperhidrosis)

Hyperhidrosis to stan, w którym występuje nadmierne pocenie się, nawet gdy nie jest się rozgrzanym lub podczas ćwiczeń. Nadmierna aktywność gruczołów potowych prowadzi do zwiększonej produkcji potu, co sprzyja rozwojowi bakterii i nieprzyjemnego zapachu. Ten stan może być tak poważny, że utrudnia codzienne życie.123

Nadmierna potliwość stóp, znana jako plantar hyperhidrosis, może być uwarunkowana genetycznie lub być objawem innych schorzeń. Osoby cierpiące na hyperhidrosis mogą wymagać specjalistycznego leczenia, aby kontrolować nadmierne pocenie się i związany z nim zapach.123

Zmiany hormonalne

Wahania hormonalne mogą znacząco wpływać na ilość wydzielanego potu, a tym samym na zapach stóp. Grupy szczególnie narażone na wpływ zmian hormonalnych to:123

  • Nastolatki – ze względu na zmiany hormonalne w okresie dojrzewania
  • Kobiety w ciąży – ze względu na zwiększoną produkcję hormonów
  • Kobiety w okresie menopauzy – z powodu wahań hormonalnych

123

Stres i leki

Stres i lęk mogą zwiększać aktywność gruczołów potowych, prowadząc do zwiększonego pocenia się stóp i nasilenia nieprzyjemnego zapachu. Reakcja organizmu na stres obejmuje aktywację systemu nerwowego, który może stymulować wydzielanie potu.123

Niektóre leki mogą również przyczyniać się do zwiększonej potliwości. Dotyczy to szczególnie niektórych leków przeciwdepresyjnych, które jako efekt uboczny mogą powodować nadmierne pocenie się.123

Niewłaściwe obuwie i skarpetki

Rodzaj noszonego obuwia i skarpetek ma znaczący wpływ na rozwój nieprzyjemnego zapachu stóp:123

  • Buty wykonane z materiałów syntetycznych (plastik, winyl) nie przepuszczają powietrza, co prowadzi do zwiększonej potliwości i rozwoju bakterii
  • Noszenie tych samych butów codziennie, bez umożliwienia im wyschnięcia, sprzyja rozwojowi bakterii
  • Skarpetki wykonane z materiałów syntetycznych (poliester, nylon) są mniej przepuszczalne dla powietrza niż skarpetki z bawełny czy wełny, co zwiększa potliwość stóp
  • Noszenie butów bez skarpetek prowadzi do gromadzenia się potu, martwego naskórka i brudu, co sprzyja rozwojowi bakterii

12

Niedostateczna higiena

Nieodpowiednia higiena stóp jest jednym z głównych czynników przyczyniających się do nieprzyjemnego zapachu. Rzadkie mycie stóp lub niezmienianie skarpetek co najmniej raz dziennie może prowadzić do nagromadzenia się bakterii na stopach, co z kolei nasila nieprzyjemny zapach.123

Zaniedbywanie usuwania martwego naskórka z powierzchni stóp również przyczynia się do rozwoju nieprzyjemnego zapachu, ponieważ martwe komórki skóry stanowią pożywkę dla bakterii.12

Schorzenia związane z nieprzyjemnym zapachem stóp

Infekcje grzybicze i bakteryjne skóry

Oprócz wspomnianych wcześniej przyczyn, niektóre specyficzne infekcje skóry mogą być przyczyną nieprzyjemnego zapachu stóp:12

  • Pitted keratolysis – bakteryjna infekcja skóry stóp, która powoduje charakterystyczne wgłębienia w skórze i wydziela nieprzyjemny zapach. Bakterie odpowiedzialne za tę infekcję uwalniają związki siarkowe o wyjątkowo nieprzyjemnym zapachu.
  • Grzybica paznokci – infekcja grzybicza, która może rozprzestrzeniać się pod paznokciami, prowadząc do ich szarzenia, kruszenia się i wydzielania nieprzyjemnego zapachu.

12

Choroby towarzyszące

Niektóre schorzenia mogą wpływać na zwiększoną potliwość stóp i tym samym przyczyniać się do powstawania nieprzyjemnego zapachu:12

  • Zaburzenia tarczycy (szczególnie nadczynność tarczycy) – mogą prowadzić do zwiększonej potliwości całego ciała, w tym stóp
  • Cukrzyca – choć sam nieprzyjemny zapach stóp nie jest objawem cukrzycy, to u osób chorujących na cukrzycę może być sygnałem niezagojonej rany lub owrzodzenia, które wymaga natychmiastowej interwencji medycznej
  • Otyłość – może wpływać na poziom hormonów, prowadząc do nadmiernego pocenia się
  • Zaburzenia krążenia – mogą prowadzić do zwiększonej potliwości jako mechanizmu kompensacyjnego

123

Wpływ diety i stylu życia

Dieta i styl życia mogą również wpływać na zapach stóp:12

  • Spożywanie pikantnych potraw, kawy, alkoholu i produktów o intensywnym zapachu (takich jak czosnek czy cebula) może stymulować produkcję potu
  • Dieta bogata w węglowodany może nasilać rozwój grzybów i bakterii
  • Nadmierne spożycie kofeiny i alkoholu może zwiększać potliwość
  • Odwodnienie może prowadzić do bardziej skoncentrowanego potu, co sprzyja rozwojowi bakterii

12

Podsumowanie etiologii bromodosis

Nieprzyjemny zapach stóp (bromodosis) jest najczęściej wynikiem złożonej interakcji między potem a mikroflorą skóry stóp. Główne przyczyny i czynniki sprzyjające to:12

  1. Nadmierna produkcja potu przez liczne gruczoły potowe w stopach
  2. Rozkład potu przez bakterie naturalnie występujące na skórze stóp, prowadzący do wytwarzania lotnych kwasów organicznych o nieprzyjemnym zapachu
  3. Specyficzne gatunki bakterii (Kyetococcus sedentarius, Brevibacterium, Staphylococcus epidermidis) odpowiedzialne za szczególnie intensywny zapach
  4. Infekcje grzybicze, takie jak grzybica stóp
  5. Nadmierna potliwość (hyperhidrosis) jako stan predysponujący
  6. Czynniki zewnętrzne, takie jak niewłaściwe obuwie i skarpetki, ograniczające wentylację stóp
  7. Niedostateczna higiena stóp
  8. Zmiany hormonalne u nastolatków, kobiet w ciąży i w okresie menopauzy
  9. Stres i niektóre leki zwiększające potliwość
  10. Choroby współistniejące, takie jak zaburzenia tarczycy czy cukrzyca

12

Zrozumienie etiologii nieprzyjemnego zapachu stóp jest kluczowe dla skutecznego leczenia i zapobiegania temu problemowi. W większości przypadków bromodosis jest schorzeniem łagodnym, które można skutecznie kontrolować poprzez odpowiednią higienę i pielęgnację stóp, jednak w przypadkach uporczywych lub związanych z innymi schorzeniami może wymagać konsultacji z lekarzem specjalistą.12

    https://www.webmd.com/skin-problems-and-treatments/what-to-know-about-smelly-feet
    The main cause of smelly feet is trapped sweat. Your feet create a lot of sweat each day since they have thousands of sweat glands. When the sweat becomes trapped in your shoes or socks, it can create a bad odor. This is known as bromodosis, or smelly feet. […] Bacteria are also responsible for smelly feet. There are many kinds of bacteria on the bottom of your feet. These bacteria live off the sweat that your feet are constantly producing. When they feed on the sweat, the bacteria create an acid that causes foot odor. […] Besides bacteria, fungus may also cause you to have smelly feet. Fungus grows and thrives in warm, moist areas. When your feet sweat inside your shoes and socks, this creates an environment where fungus can grow. These bad-smelling fungi are commonly known as athletes foot.

  • #1 Foot odor – Wikipedia
    https://en.wikipedia.org/wiki/Foot_odor
    The main cause is foot sweat (also see focal hyperhidrosis). Sweat itself is odorless; however, it creates a beneficial environment for certain bacteria to grow, producing odorous substances. These bacteria are naturally present on our skin as part of the human microbiome. The front part of the foot produces the most sweat. […] The smell is exacerbated by factors that increase sweating, such as wearing closed-toe shoes. Sports footwear such as sneakers is often heavily padded inside which provides a perfect environment to trap moisture and allow the bacteria to thrive. Socks can trap foot hair, especially on the toes, and may contribute to odor intensity by increasing surface area on which bacteria can thrive. […] Given that socks directly contact the feet, their composition can affect foot odor. Synthetic materials like polyester and nylon afford less ventilation to the foot than do cotton or wool, leading to increased perspiration and odor, although they can also reduce incidence of blisters by wicking away perspiration.
