Why does my armpit sweat have an odor in winter?

Under normal circumstances, "ge zhi wo" refers to the armpit (axilla). Excessive sweating in the armpits during winter accompanied by odor may be caused by various factors such as temperature regulation, emotional fluctuations, hyperhidrosis, hyperthyroidism, and diabetes. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Temperature Regulation

To maintain a constant body temperature, the human body secretes sweat through sweat glands during physical activity or when body temperature rises, which can lead to armpit sweating and associated odor. Maintain an appropriate room temperature, avoid wearing excessively heavy clothing, and choose breathable fabrics.

2. Emotional Fluctuations

Emotional states such as tension, anxiety, or excitement may also trigger increased sweating in the armpits along with odor. Learning relaxation techniques such as deep breathing, yoga, or meditation can help manage emotions effectively.

3. Hyperhidrosis

Hyperhidrosis may result from abnormal activity of the autonomic nervous system, causing overproduction of sweat by sweat glands. This manifests as excessive armpit sweating, where sweat interacts with bacteria on the skin surface to produce odor. It may also be accompanied by excessive sweating in other areas such as the palms and soles. Symptoms can be alleviated under medical supervision using medications such as atropine sulfate tablets, propantheline bromide tablets, or diazepam tablets.

4. Hyperthyroidism

Hyperthyroidism is generally associated with genetic factors or certain diseases. Excessive secretion of thyroid hormones increases the body's metabolic rate and enhances sweat gland activity, leading to armpit sweating with odor. Other symptoms may include palpitations and anxiety. Treatment under a doctor’s guidance may include medications such as methimazole tablets, propylthiouracil tablets, or metoprolol tartrate tablets.

5. Diabetes

Diabetes may be triggered by genetic and environmental factors. High blood glucose levels can damage nerve fibers, particularly affecting the function of the autonomic nervous system, resulting in dysregulation of sweat glands. This may lead to abnormal sweating, including increased armpit sweating with odor. Additional symptoms may include thirst and frequent urination. It is recommended to undergo treatment under the supervision of a healthcare professional using medications such as gliclazide tablets, metformin hydrochloride tablets, or rosiglitazone hydrochloride tablets.

Maintain healthy lifestyle habits, follow a light diet, and ensure adequate sleep.
