दारु/शराब/बीयर पीने के बाद नशा क्यों आता है? How Alcohol Affects Your Brain (नशा जल्दी कैसे उतारें?)

Myself Dr. Vakeel Khan, and in this video, I have explained in detail why alcohol (दारु/शराब/बीयर) causes intoxication and how it affects your brain—“नशा क्यों आता है?” I have also discussed some effective tips on “नशा जल्दी कैसे उतारें?” To make the topic clear, I have explained the complete journey of alcohol inside the body—from the oral cavity (मुखगुहा), pharynx (ग्रसनी), esophagus (अन्ननली), stomach (आमाशय), small intestine (छोटी आंत), duodenum (ग्रहणी), and large intestine (बड़ी आंत). I have shown how alcohol is absorbed and transported through the portal vein (पोर्टल शिरा) to the liver (यकृत), where it is broken down by the Alcohol Dehydrogenase (ADH) enzyme and Aldehyde Dehydrogenase (ALDH) enzyme. I have highlighted the role of the gallbladder (पित्ताशय), inferior vena cava (अवनिम्न महाशिरा), heart (हृदय), and finally, how it reaches the brain (दिमाग). Inside the brain, I explained the impact of alcohol on the GABA neurotransmitter (गाबा न्यूरोट्रांसमीटर) and Gamma Aminobutyric Acid (गामा-अमीनोब्यूटिरिक अम्ल), how it depresses brain function—especially in the frontal lobe (ललाट खंड)—and increases the dopamine hormone, which leads to the feeling of pleasure or “high.” This video provides a scientific yet simplified explanation of how alcohol affects your body and brain.
