About this episode
What does alcohol really do to your brain, mental health, hormones, and overall wellbeing? In this AMA episode, Dr. Kash Gupta explains how chronic alcohol use can affect brain volume, memory, decision-making, impulse control, mood, sleep, and executive function — and unpacks serious complications linked to thiamine (vitamin B1) deficiency, including Wernicke's encephalopathy and Korsakoff syndrome.
Dr. Gupta explains why alcohol may initially feel calming but can eventually worsen anxiety, poor sleep, depression, and emotional wellbeing. He also discusses the relationship between alcohol use and suicide risk, including how alcohol can affect mood, motivation, neurotransmitters, and impulse control.
The episode explores genetic vulnerability to alcohol — including differences in alcohol metabolism and family history — and why alcohol dependence shouldn't be viewed through stigma alone. It closes with a look at how long-term alcohol consumption can affect testosterone, sperm quality, erectile function, menstrual cycles, ovulation, fertility, estrogen metabolism, and sexual health in both men and women.
