david samadi is here, chief of robotic surgery. great to see you. >> happy sunday. >> we are going to begin with a spotlight on national multiple sclerosis week, an illness that affects 2.3 million people worldwide. it can strike without warning. how do you know when you're starting to have symptoms of ms. is early detection important? >> hugely important. the problem is that ms is known as the great imitator. it can mimic almost any neurologic disease. you could have weakness. you could have fatigue, a really important one. i interviewed ann romney last year, that's her prominent symptom. fatigue, suddenly getting fatigued. that's hard to know. fatigue can be many different things. it can be sensory loss where you can get confused, depressed. the most permanent one is optic neuritis where you suddenly lose vision in your eye. you have an episode where you have a problem and it remits. the best way to understand it is like wiring. the wiring of the brain is like copper wire. nerves are like wires. the outside of the wire is insulat

samadi i think it just takes the right guy. if there's a pill that can help, why don't they approve it? i made you blush, go ahead. >> we're just celebrating 15 years of viagra. that really changed the way we practiced medicine. for us, for men, it's easy. this is a mechanical problem, it's a plumbing issue. you take the viagra, it brings the blood flow to the male organ or penis and it works really well. with women it seems to be totally different and the diagnosis is really this hypo meaning the libido or the drive is not there and difficulty with arousal and it's much more complex. it's not just plumbing issues or blood to the area. something in the brain, the exchange between the dopamine and sar atonen. we know it's not just mechanical. it's emotional, psychological. the chemistry has to be there, the right guy has to be there. all of that has to work in before this kicks in. now -- >> so what's this drug? >> fda has looked into this. it's a medication that research was done about three years ago. they looked at about 1900

samadi? i never mentioned it. you mentioned hydroxy something.can raise your blood pressure and it can make you -- >> sugar. first of all, you have to know how to pronounce it before you -- it's called garciniacambosia. this is from south asia. it became very popular because a lot of people started to endorse this. people lose weight as a result of this. >> honestly, or did you -- >> no, no, but look at what happened. it increases your serotonin so you're not going to have that crave and emotional eating. that's one part of it. it converts the sugar to fat and people lose weight. here is the trick. you're not going to be able to take this forever. you should only take it for about three months. and how much weight are you going to lose in three months? five pounds? ten pounds? so it's not that revolutionary thing. the side effect is minimum. it seems to be safe. but if you're pregnant, if you're bred feeding, you should not touch this. >> diabetic a as problem because it is the point you made, that it converts sugar to fat. >> if you want to lose

samadi, how important in this? i can't stress it enough, get a colonoscopy. it is so important. it's such an avoidable disease. >> yes, 140,000 americans diagnosed with colon cancer every year, 50,000 die from this. you're right. it's the second leading cause of cancer deaths. this new dna-based colon screening test that just is coming in under approval by fda is extremely important. exact science corp is the name. a lot of people always ask -- the actual test will be called colo-guard. it's based on a stool test. if there's any there's any cancer, it will shed some cells that will go if the stool and we can find out if there's any cancer or not, which will probably reduce the number of colonoscopies or anything added to what we do. >> how far in advance can you detect it, do you think? >> that's an excellent point. 13,000 patients. they were able to find out 92% accuracy of early organ-confined colon cancer, which is a being deal. in the most advanced ones, 42% accuracy. not so great, but for the first stage, this is actually great. what it would tell us is you can bring the st

david samadi, chairman and professor and chief of robotic surgery. >> and dr.siegel at ny medical center and author of unlocking the secret code of sickness and health. it's great to see both of you. >> good to see you. >> i want to start with a women's health question. often these diseases are referred to as women's diseases but

samadi. let's get things moving. >> that's a good one. so for a week of constipation, i would say look into dehydration and fiber. i wouldn't worry about this. watch how much you are drinking. there's some diseases we need to worry about. some of it is manmade. about 50% of constipation in the u.s. is caused by us surgeon egg. we have tylenol number 3, in urology, we give out a lot of bladder spasm medications. all of them cause constipation. the other 80% of constipation in the u.s. is as a result of this man. he's the one that makes everyone constipated. how much? too much calcium supplements. he's proud of it. antidepressants and diuretics, that's going to get rid of it. congratulations. there are treatments that mark is going to talk about now. >> what is the safest way to go? do you use laxatives because people don't know what to do. >> he covered that beautifully. i want to add a couple of things. if you've traveled recently or if you're sediment tear, that could cause it. and a week of constipation is not something to worry about,

david samadi.outside so those in mild comas and they started getting reaction in belgium. what can you tell us about this? >> this is a fascinating study coming from belgium. these are the people, about 55 of them. half of them are in completely vegatative state, they have no brain activity. and half have minimal consciousness. they put probes on the side of their brain and did a very superficial stimulation of the brain. about half of those started to have some reaction. they were able to squeeze your finger, able to move their eyes. this is quite interesting. >> then they go back? >> about 20 minutes of system lace, -- 20 minutes of stimulation they are able to show some signs of life and after that they go back to the coma. what we learned is the brain is very fluid and plastic. we're learning about the wiring of the brain, which is very interesting. this test could be used to distinguish someone who is in a vegatative state versus consciousness. that can be used for diagnostic tools. one of the

gregg: well, david samadi, good to see you. congratulations. this is big news in your field.l right, jenna? jenna: disabled athletes proving anything is possible as the paralympic games get underway in sochi. we're going to introduce you to a blind teenager who's determined to ski her way to a gold medal. so you could drive from los angeles all the way philadelphia with just three stops for fuel. that's just a hop, skip, and a jump. try that in another midsize sedan. it's more of a hop... a skip... a jump... a leap... maybe a schlep... probably a hurdle... a little bit of a trek... avo: during the tdi clean diesel event, get a $1,000 fuel reward card and 0.9% apr for 60 months. >> hey, what are you doing? >> drink. >> you're plying me with liquids? >> i gave it up for lent. >> ooh, the strong stuff. did you hear about the casino who gave the guy too many drinks and now he's suing them? >> he's suing the casino. >> because they plied him with drinks. >> the casino gave him booze? >> that's what they do. whose responsibility is it? we'll debate that. jenna: the paralympic winte

david samadi. a parent as well as i am and kelly is. kids not getting enough sleep. we didn't realize it could have long-term risk factors. >> we know this in adults. you're bringing this to the level of teenagers. we know if the lack of sleep means diabetes, high blood pressure or risk of stroke, you have prolonged life to deal with this disease. 65% of americans are suffering from overweight and obesity. we see type 2 diabetes from kids younger than 10 years old is on the rise. this is a huge problem. what they did was look at kids, teenagers between 11 and 17. they followed them about a week and they found out only 30% of the group are getting about seven hours of sleep. nobody is getting enough to 8.5 to 9 hours. only 5%. this is a problem. what they want you to think of is just the same way blood pressure, high cholesterol and diabetes causes cardiac risk factors, lack of sleep could be another risk factor. >> why? what is the connection? >> a lot of metabolism changes going on between insulin and sugar. when you don't sleep enough

samadi. thank you so much. >> coming up, new e-mails show just how far health officials will go to push obama care and silence fox news. we'll show them to you. a veteran not loving the treatment he got at mcdonald's. he says he was kicked out of the restaurant for sitting there too long. really? first a happy birthday to rupert murdoch the ceo of news corp, the parent company of the fox news channel. he turns 83 years old today. my name is karen and i have diabetic nerve pain. it's progressive pain. first you have that, that feeling of numbness. then you get the hot pins. it got to the point where i felt like, almost like lightning bolts, hot strikes into my feet. the pain was, it was... i just couldn't handle it, so my doctor prescribed lyrica. the pain has been reduced and i feel better than i did before. [ male announcer ] it's known that diabetes damages nerves. lyrica is fda-approved to treat diabetic nerve pain. lyrica is not for everyone. it may cause serious allergic reactions or sui

david samadi. good morning. i hold in my hand twoç delicious chocolate bars.turn your health around? >> this is a very exciting study and i personally, if it pans out, i will take one of these pills. the reason is because we're talking about flavanoids. they are the chemicals in chocolate, red wine, that are antioxidants that dilate the vessels. what kills us? in everything you said, diabetes, high cholesterol. if you're going to have the good part of the chocolate that will open the vessels, you're not going to have stroke and heart disease because your blood pressure will come down. recruiting 18,000 men and women, giving them these flavonoids and see if it will pan out. >> with the chocolate pill, they're taking the good stuff, the flavonoids and super concentrating it. we've heard eat dark chocolate, they are good for you. they are taking those good properties and putting it in that super pill. >> this is a new study. over the next four years they are going to put it blind sided, both researchers and patients don't know what they're taking. once you take t

david samadi from our medical a team. good morning. tell us how this study works exactly.higan and texas from about 400 couples. >> they took 400 couples and they did a saliva test and they looked at a hormone. when you're under a lot of stress that hormone goes up in the saliva. they noticed with couples that are under a lot of stress, they are less likely of becoming fertile. what this is telling us is what does stress do to yourdy. we know a lot of times when you're under a lot of stress your addrenal gland kicks in. what does itç do to fertility among women? this is one of the first studies we're seeing that it can actually affect them. the good thing is 87% of the couples were able to have children and give birth, but 13% had a problem. they also counted for cigarette smoking, alcohol and coffee. >> a lot of times with more stress we turn to something and for a lot of times it is cigarettes or alcohol. what do we need to do to stay away from that if we're trying to get pregnant? >> you have to rule out mechanical issues, obstructions of the tubes and ovaries. number
