Hyperhidrosis and how botox treats it
Hyperhidrosis is a medical condition that can significantly affect quality of life, social interactions and emotional well-being. Excessive sweating commonly affects the underarms (axillary hyperhidrosis), palms, soles and sometimes the face. When topical treatments and oral medications are insufficient, botulinum toxin injections are one of the most effective and scientifically supported options.
Hyperhidrosis occurs due to overactivity of the sweat glands, driven by nerve signals. Botulinum toxin works by temporarily blocking the nerve stimulation of the sweat glands, dramatically reducing sweat production in the treated area without affecting the body’s ability to regulate temperature.
