Sweating is a natural response that helps the body cool down and flush out waste. However, health experts say there are times when sweating goes beyond what is normal. When it becomes heavy, persistent, or occurs without heat or physical exertion, it may point to an underlying medical issue.

According to medical professionals, excessive sweating, known clinically as hyperhidrosis, is one of the most common conditions linked to abnormal perspiration. Hyperhidrosis occurs when sweat glands become overactive, causing people to sweat excessively on areas such as the palms, feet, underarms, or face. The condition can affect individuals even in cool weather and often disrupts daily activities, social interactions, and work routines.

Hormonal and metabolic disorders

Meanwhile, thyroid disorders are another major cause of unusual sweating. Hyperthyroidism, a condition in which the thyroid gland produces too much hormone, speeds up the body’s metabolism. According to endocrinologists, this often leads to symptoms such as excessive sweating, unexplained weight loss, rapid heartbeat, anxiety, and sensitivity to heat. Many patients, however, overlook sweating as a warning sign and fail to seek early medical attention.

Diabetes has also been linked to abnormal sweating patterns. According to reports from health practitioners, low blood sugar levels can trigger sudden sweating episodes, particularly at night. In addition, long-term diabetes may damage nerves that control sweat glands, resulting in excessive or uneven sweating across different parts of the body.

Infections and other triggers

Excessive sweating may also be associated with infections and chronic illnesses. Conditions such as tuberculosis are known to cause night sweats, often accompanied by fever, persistent cough, and fatigue. Doctors say these symptoms should never be ignored, especially in regions where infectious diseases remain prevalent.

Hormonal changes during menopause, anxiety disorders, and certain medications, including antidepressants and blood pressure drugs, can also increase sweating. According to medical experts, these triggers are often overlooked because sweating is widely seen as harmless.

When to seek medical help

Health professionals stress that persistent or unusual sweating deserves attention, particularly when it occurs alongside other symptoms such as weight changes, chest pain, fever, or extreme tiredness. While sweating alone does not always indicate disease, experts say its severity, timing, and pattern can provide important clues.

Speaking on the issue, a Lagos-based physician explained that early medical evaluation makes a significant difference. According to him, identifying the root cause early allows for easier treatment and reduces the risk of complications.

Ultimately, doctors advise people to pay close attention to changes in their bodies. Acting promptly and consulting a healthcare professional when symptoms persist remains one of the simplest and most effective steps toward protecting long-term health.
