The video features a discussion between the host and Squeaks about hiccups. It explains that hiccups occur when the diaphragm spasms, causing quick intakes of air. The diaphragm is a muscle below the lungs that aids in breathing. Hiccups can be triggered by various factors, including eating quickly or certain medications. The sound of a hiccup is produced when the vocal folds in the throat slap together. Remedies like drinking water can help stop hiccups by normalizing diaphragm movement, but sometimes they persist and need to be waited out. The video concludes with an invitation for viewers to ask questions.
