Excessive sweating all over the body can occur due to anxiety, stress, obesity, thyroid problems, diabetes, infections, hormonal imbalance, medications, or a condition called hyperhidrosis. Treatment depends on the underlying cause, so it is important to identify why it is happening. Doctors may advise tests such as thyroid profile, blood sugar, and general blood tests. In some cases, medicines such as Glycopyrrolate or prescription antiperspirants may be considered under medical supervision. Wear loose cotton clothing, stay hydrated, avoid excessive caffeine and spicy foods, and maintain good hygiene. Please consult a physician or dermatologist if sweating is severe, associated with weight loss, palpitations, fever, or occurs mainly at night.
