Hormones shape each and every one of us, affecting almost every aspect of our lives - our height, our weight, our appetites, how we grow and reproduce, and even how we behave and feel.
This documentary tells the wonderful and often weird story of how hormones were discovered.
Presenter John Wass, one the country's leading experts on hormones, relates some amazing stories - how as recently as the 19th century boys were castrated to keep their pure soprano voice, how juices were extracted from testicles in the hope they would rejuvenate old men and how true medical heroes like Frederick Banting discovered a way to make insulin, thus saving the lives of countless diabetes sufferers.
And hormones remain at the cutting edge of medicine as we try and deal with modern scourges like obesity.

@dganet 2 года назад

Bloody fascinating! My husband screamed out with a severe headache & had stroke like symptoms 2.5yrs ago....we thought the worst! Turned out he had a congenital pituitary tumour that burst! Doctors decided to treat it by steroids & other tablets, other than an operation......so far it's better.......my PCOS unfortunately still leaves me infertile & it looks like I've gone into early menopause.... endocrinology sometimes works but it doesn't always! Great documentary however ❤️xxx

@honeybunch5765 2 года назад

Wow that is scary, glad he is ok. I also have PCOS, horrible syndrome that only those with it understands, it has such a debilitating effect on our bodies as well as our minds. To the world we do not seem sick and when you suffer with weight gain they just think you are lazy and don't take care of yourself. The whole infertility part of it is heart breaking on its own. I'm 50 now had invitro at 35 but my husband died a few days before I was supposed to go in for extraction of my eggs. It's a painful acceptance not to have a child of your own, my heart goes out to you.❤

@toni4729 Год назад

I'm well aware of the fact that hormones can be seriously effected by medication and that can make you gain weight. It happened to me, and no matter how little I ate it made no difference. At the age of forty my weight went from 48kg to 101kg in a little over a year. It cost me my gallbladder and because of this I remained that weight for twenty years until it was finally put down to my thyroid. Because my gallbladder had been removed it seems I couldn't lose the weight after I'd been taken off the meds.

@middleofnowhere1313 Год назад

My thyroid bit the dust too. Along with this came diabetes. I've got meds and lost the weight but good lord all the problems that still exist for me daily because of this endocrine disruption.

I never paid much attention to the subject until recently after 3 marriages and plenty of gfs in between, I met a good looking woman that, in her presence anyway, I became a complete idiot. I mean, my heartbeat increased, I couldn’t speak correctly because of dry mouth, I literally tripped over my feet, it was fucking pathetic and ridiculous. She had complete control over me and my bank account. When I wasn’t around her I was fine. I never had that problem before with any woman so I was dumbfounded and she knew it. I’m lucky I got away but that is my first encounter with the power of pheromones!

Thank you, I really enjoyed the documentary, and yeah a little bit of knowledge is dangerous. The worst thing is that many people claimed to be very very sure when they are discussing science based on old researches or even new. Science mean doubt and then have a strong clue based on observations and experiments and waiting while there is new discovery . It's a renewable process as we live we know more and new things.

@seanriopel3132 Год назад

Reminds me of a fascinating BBC docu about a young woman wanting to change her sex to a man. A year before the gender reassignment surgery, she started on a course of HRT. The before tests of her cognitive, creative, social and physical skills were diametrically opposite those of the same tests conducted 6 months later. She gained muscular dexterity and improved hand-eye coordination, greater physical strength, better control over her emotions, etc., but key social skills were drastically reduced, as well as her ability to multitask, communicate verbally, and her stamina declined significantly. Her personality changed too. And all (only) because of the hormones!

Amazing and fascinating documentary. I do quibble with the assertion that leptin, without exception controls your weight as it does not account for the ability to exercise free will and conscientiously eat less and exercise more, thereby influencing body weight. I realize Dr Wass and the leptin presenter are not good examples of the free will argument , but there are many people who have overcome obesity through sheer will power and they should be given their due.

If you are obese I highly recommend Psyllium husk it's helps regulate your digestive system and if you drink it in a smoothie it expands to fill your belly. Also stop eating garbage... your body requires a simple regime and has a hard time coping with excessive consumption, you are using more energy to try and digest food than you are taking in and that is why you are tired all the time. Eat three meals a day, drink three litres of water, do 20 mins of yoga and go to bed for eight hours. Do this and you will feel like a new person in six weeks... I promise x You are the universe
