What causes limb numbness after drinking alcohol?

Limb numbness after alcohol consumption may primarily involve the following possible causes: 1. Physiological reaction: Excessive alcohol intake can lead to alcohol accumulation in the body, causing blood vessel dilation and increased blood flow, which may result in overall numbness, including limb numbness. 2. Hypotension: Long-term alcohol consumption may induce hypotension, which can cause symptoms such as listlessness, limb weakness, and numbness in hands and feet. 3. Multiple peripheral neuritis: Chronic alcohol abuse, cold weather, and other factors may lead to multiple peripheral neuritis, manifested as sensory, motor, and autonomic nervous system dysfunction, resulting in symptoms such as muscle weakness, atrophy, and numbness. 4. Compressive injury: After drinking alcohol, people may rest or sleep in abnormal positions, leading to prolonged nerve compression and poor local blood circulation, causing temporary limb numbness. 5. Alcohol allergy: Some individuals are allergic to alcohol, and after drinking, they may experience allergic symptoms such as overall numbness and difficulty breathing. If limb numbness persists after alcohol consumption or is accompanied by other severe symptoms, prompt medical attention is recommended.
