Hyperhidrosis - What is it? how can i prevent blisters and tinea?

What is Hyperhidrosis?

Hyperhidrosis is categorised as abnormal excessive sweating in the extremities of the body.

This not usually linked to heat or partaking in exercise.

Primary Hyperhidrosis is caused by faulty nerve signals that trigger sweat glands to become overactive.

Secondary Hyperhidrosis can be because of underlaying medical conditions such as diabetes, some cancers and nervous system disorder or medications such as pain relievers or hormonal medications.


  • Infections such as Tinea Pedis (a fungal infection of the skin) caused from an environment with increased moisture.

  • Blisters from increased friction from sweat.

  • Malodorous feet and shoes.

What can you do at home ?

  • Use antiperspirant and deodorising sprays for feet and shoes to help with decreasing sweating and to help with odour.

  • Wear natural fibre socks like Bamboo which are moisture wicking, such as OS1st socks.

  • Use a blister stick to help prevent blisters.

  • Change socks daily and wash regularly.

  • Rotate shoes as to not wear the same ones all of the time.

  • Use an anti fungal solution when washing socks, if a fungal infection is present.

What can a Podiatrist do to help?

  • Footwear education to ensure that you are wearing shoes that have correct width and depth, to help reduce the chance of blisters occurring from friction.

  • Assess feet for any infections such as Tinea Pedis and recommend a course of treatment such as terbinafine spray and to use anti fungal solution when washing socks and bath matts.

  • Recommend sock fibres to help with moisture wicking.

  • Sterilise shoes to get rid of Fungal spores if a Tinea Pedis infection is diagnosed.

  • Provide foot sprays to help with malodorous feet and/or shoes.

  • Provide advice and blister care if needed.

  • Come up with a treatment plan to prevent recurrence.
