Reddish eczema with underarm sweating

Red rashes with sweating under the armpits may be caused by physiological factors, or could result from sweat irritation, fungal infection, and other factors. Targeted treatment under medical guidance is recommended. Specific analysis is as follows:

1. Physiological Factors

The sweat glands under the armpits are well-developed, leading to increased local perspiration. If not properly managed, prolonged dampness in the armpit area can easily lead to red rashes (eczema). It is important to maintain good local hygiene and take regular baths.

2. Pathological Factors

1) Sweat Irritation

Excessive sweating under the arms may irritate the skin, causing eczema. In such cases, sweat should be cleaned off first, followed by treatment with medications such as desonide cream, pimecrolimus cream, or tacrolimus ointment as directed by a physician.

2) Fungal Infection

The moist environment created by excessive underarm sweating promotes fungal growth. Prolonged exposure may lead to localized fungal infection, which in severe cases can coexist with eczema. In such instances, antifungal medications like clotrimazole, ketoconazole, or miconazole may be used under a doctor's advice.

In addition to the above causes, allergic reactions, endocrine disorders, or immune system abnormalities may also contribute. It is advisable to seek timely medical evaluation and treatment. Maintain dry and clean skin, and wear loose-fitting clothing regularly.
