Differential Diagnosis for Strong Foot Odour
- Single most likely diagnosis
- Hyperhidrosis: This condition is characterized by excessive sweating, which can lead to strong foot odour due to the bacterial breakdown of sweat. It is a common condition that affects many people, making it the most likely diagnosis.
- Other Likely diagnoses
- Poor foot hygiene: Infrequent washing of the feet, especially between the toes, can lead to the accumulation of bacteria and fungi, causing strong odour.
- Fungal infections (e.g., athlete's foot): Fungal infections can cause foot odour due to the breakdown of skin cells and sweat by fungi.
- Bacterial infections (e.g., pitted keratolysis): Certain bacterial infections can cause foot odour by breaking down sweat and skin cells.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Diabetes: Uncontrolled diabetes can lead to foot ulcers and infections, which can cause strong foot odour. If left untreated, these infections can lead to serious complications, including amputation.
- Peripheral artery disease: This condition can cause poor circulation to the feet, leading to tissue death and strong odour. If left untreated, it can lead to gangrene and amputation.
- Rare diagnoses
- Isovaleric acidemia: This is a rare genetic disorder that affects the breakdown of certain amino acids, leading to the production of isovaleric acid, which can cause strong foot odour.
- Trimethylaminuria: This is a rare genetic disorder that affects the breakdown of trimethylamine, a compound found in certain foods, leading to strong body odour, including foot odour.
- Eczema (dyshidrotic eczema): This is a rare type of eczema that affects the feet and can cause strong foot odour due to the breakdown of skin cells and sweat.
