My professors at uni are some of the most renowned scientist in the world when it comes to GI physiology, and yet here I am appreciating the heck out of Zach and the rest of the NN team. You guys are teaching me so much more than my professors. So thank you immensely

I had total syncope with really frightening black out three times over about 9 days and each time after eating last bite/last spoonful of food. I had had GERD for some years that I know know is CAFFEINE ALLERGY that gave mea stinging pain either side of my throat before the usual acid reflux started. The stinging started immediately after usual light breakfast of slice of bread or toast with butter and usually some jam or marmalade. During rest of day the GERD was slight and if worse I took antacid. Then I started getting a pain at bedtime when lying on left side and had to turn over onto right that made the pain almost disappear. If I turned back left i almost heard and felt a heaviness sort of slopping over as though my esophagus was filled with food or drink that had not progressed down into my stomach over the 1-2 hours since last meal or drink. I wondered if the lower lower esophageal sphincter LES was not opening to allow the last meal to pass into the stomach. This went on for several weeks at the time had first COVID lockdown made it impossible to get doctors appointment. Then I had the first of the three syncopes and finally managed to call a doctor who immediately said it sounded as though I might have a esophageal cancer and arranged an endoscopy. That took a month due to COVID delays. I only had a drink of water several hours before the endoscopy and was surprised to see enting esophagus, stomach and first few inches of small intestine looked healthy and pink and the doctor said no sign of cancer or other problems. Just after the endoscopy I noticed I had the pains in throat and reflux after a breakfast of tea and a rye crispbread. I reasoned that the rye was so innocuous that maybe the tea was the culprit though as I'd been drinking tea for at least 70 years it seemed ridiculous. But I searched the medical literature and found that a caffeine allergy can develop and give reflux. I immediately stopped drinking tea and bought and drank decaf coffee and almost all the gerd has disappeared except for a slight sore throat if I make the coffee a little strong. Therefore I think this is what happens with GERD-SYNCOPE is actually a SPHINCTER PARALYSIS. The caffeine induces GERD. The GERD irritates the esophagus and LES. Eventually the GERD irritation causes the LES to fail to open so that the last meal remains in the esophagus to give that feeling of food at the back of the throat. At some point after this LES paralysis spasm develops a meal will so fill the esophagus that it causes pressure on the adjacent windpipe sufficient enough to starve the lungs of oxygen, The lack of oxygen then starves the brain and causes the SYNCOPE BLACKOUT! The syncope causes a self-preservation reflex of deep swallowing and deep breathing that restores the oxygen supply to the brain. As I now eliminate all caffeine and GERD inducing food from my diet by carefully checking ingredients of all food and drink I have little GERD and no sensation of esophagus being filled with unpassed food.

[@urmothwr]

Love the lectures, you're really a lifesaver. I do have one **small** gripe though - there's been a few misspellings and mispronounciations, so for foreign student's it'd be great to adress (in this case, you wrote down achlasia, which is missing an "a" - achAlasia. In other vids the ones I picked up on may be just brit vs american english - you sat muh-doo-lah, Isay muh-dull-ah). Also, I think everyone can agree at least on this one - it would be great if you started revisiting these same lecture topics, considering the research advances we've made in the last 5 or 6 years. Another good thing would be to include figures where sources vary - e.g. the kidney videos where you mentioned they vary in regards to magnesium absorption. I'd love to see how big that difference between the sources is! I don't want the message to seem negative, because it really isn't supposed to be. Again, thank you for all that you do - you've probably saved more med students and therefore doctors from failure than any other singular academic in the world. You don't need me to tell you that, though - the comments prove that point. Just wanted to give feedback, regardless of however little it may (or may not) matter. Again, we love you Zach, you're our saviour!
