If you have diabetes and suspect you have athlete's foot (Tinea pedis), it is important to consult your doctor or podiatrist. Athlete's foot is a common fungal infection that causes itching, burning, and cracked, scaly skin between the toes [\[1\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S1>). Although over-the-counter treatments are often effective, diabetes may increase the risk of complications, which necessitates a medical evaluation to determine the most appropriate treatment plan [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>).

## The Importance of Early Diagnosis and Treatment

Early diagnosis and treatment of athlete's foot is crucial, especially for people with diabetes. Fungal infections can lead to cracks in the skin, which may become gateways for bacteria to enter and cause secondary bacterial infections [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). These secondary infections can be more serious and require additional treatment, such as antibiotics. Your doctor can usually diagnose athlete's foot by simply looking at the skin, and may request tests like a KOH exam to confirm the presence of fungus [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>).

## Signs and Symptoms of Athlete's Foot to Watch For

People with diabetes should check their feet regularly for any changes. Common symptoms of athlete's foot include: peeling or flaking skin, especially between the toes or on the side of the foot; redness and itching; or the appearance of blisters that may ooze fluid or crust over [\[1\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S1>) [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). If the infection spreads to the toenails, they may become discolored, thick, or crumbly [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). Any of these signs warrant medical consultation.

## Treatment Options and Self-Care

In most cases, athlete's foot can be managed using over-the-counter antifungal powders or creams containing ingredients such as miconazole, clotrimazole, terbinafine, or tolnaftate [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). It is important to continue using the medication for one to two weeks after the infection has cleared to prevent it from returning [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). Additionally, keep your feet clean and dry, especially between the toes; wash your feet well with soap and water and dry them carefully twice daily [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>).

## When Should You Call a Doctor?

You should contact your healthcare provider immediately if athlete's foot symptoms do not improve within 2 to 4 weeks of self-care, or if the infection recurs frequently [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). You should also seek urgent medical care if your foot becomes swollen and warm to the touch, especially if there are red streaks or pain, as these could be signs of a potential bacterial infection [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). The appearance of pus, discharge, or fever are also indicators that require prompt medical intervention [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>).

## Tips for Daily Prevention

To help prevent athlete's foot, keep your feet clean, dry, and cool [\[1\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S1>). Wear clean socks and change your socks and shoes as often as necessary to keep your feet dry [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). Wear well-ventilated shoes made of natural materials like leather, and avoid plastic-lined shoes [\[2\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S2>). Do not walk barefoot in public, damp places like public showers or swimming pools; wear sandals or flip-flops in these areas [\[1\]](<https://clinicsjo.com/en/faq/what-to-do-if-i-have-diabetes-and-suspect-athletes-foot#source-S1>).
