What should you know about sweaty feet diabetes?

Feet may sweat because of warm footwear, stress, an inherited tendency, or plantar hyperhidrosis, a condition in which the soles sweat more than needed for cooling. Diabetes may alter the nerves that regulate sweat glands, sometimes producing unusual sweating patterns rather than simply sweaty feet. A clinician may ask about thirst, frequent urination, fatigue, weight change, numbness, and changes in sweating elsewhere. Moist skin can also soften and crack, making irritation or Athlete's Foot more likely.

Read about [Excessive Sweating](/symptoms/excessive-sweating/) and [Athlete's Foot](/conditions/athletes-foot/) to compare related symptoms.

Wash and dry carefully between the toes, change damp socks, and choose breathable footwear that can dry between uses. Avoid sharing shoes or towels if there is scaling or itching. If you have diabetes, keep glucose care and foot checks part of your routine, and do not apply irritating products to cracked skin. A clinician can assess circulation, sensation, skin changes, and whether testing for diabetes is appropriate. Options may include [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) or [Iontophoresis](/treatments/laser-and-energy/iontophoresis/) when excessive sweating is confirmed.

Arrange a medical visit for new sweating with thirst, frequent urination, unexplained fatigue, numbness, or a clear change in sweating. Seek prompt foot care for a wound, spreading redness, warmth, swelling, drainage, darkening skin, or fever, especially if you have diabetes or reduced sensation.

Could my sweating pattern reflect a nerve or glucose problem? Should my feet be checked for reduced sensation, fungal infection, or skin breakdown? Which treatment is suitable if the soles remain wet despite footwear changes?
