"Is excessive sweating under the arms always a sign of body odor (bromhidrosis)?"

Excessive Underarm Sweating: Causes and Solutions

Excessive underarm sweating does not necessarily indicate body odor. It can stem from non-medical factors such as environmental, dietary, and psychological influences, or it may be attributed to medical conditions like hyperhidrosis, bromhidrosis, and diabetes. Below are the potential causes and corresponding recommendations.

Non-Medical Factors:

1. Environmental Factors: Hot weather or wearing excessive clothing can lead to increased sweating, including under the arms. This is generally normal and does not require specific treatment. Reducing clothing can help alleviate the symptoms.
2. Dietary Factors: Consuming spicy or pungent foods like peppers and garlic may irritate the skin, causing excessive underarm sweating. It is advisable to adjust dietary habits, favoring milder foods.
3. Psychological Factors: Prolonged stress can stimulate the sympathetic nervous system, resulting in increased underarm sweating. Maintaining a positive mindset, avoiding excessive stress, and listening to relaxing music can help manage this.

Medical Factors:

1. Hyperhidrosis: Typically caused by genetics or hormonal imbalances, this condition results in excessive sweating, particularly in hot weather, accompanied by irritation and unpleasant odor. Treatment options include medications like chlorpromazine and oryzanol, taken as prescribed by a doctor.
2. Bromhidrosis: Characterized by overactive sweat glands, this condition is more pronounced in summer and emits a pungent odor. Topical application of aluminum chloride hexahydrate solution, such as Xylocaine, can be prescribed for management.
3. Diabetes: Insulin deficiency can cause symptoms like increased thirst, urination, and appetite, leading to weight loss. Management involves medication like metformin hydrochloride extended-release tablets, taken as prescribed.

Other potential causes include hyperthyroidism. If you experience significant discomfort, promptly consult a healthcare professional for tailored treatment.
