samadi suggested this topic, and i'm glad he did. there was a big survey of a small number of people that came from across the pond in england that said four out of five people in ec england say they're moderate drinkers. two out of three said we're not stopping. we're going to keep doing it. there's a big study that says we're too many binge drinkers. 40% of college have at least one episode of binge drinking over the last month. that's tremendous. why am i worried about binge drinking? because binge drinkers tend to begin with. they might be a moderate drinker. they have a weekend where they drink a lot. the new study shows they're damaging their liver. if you're having a couple of drinks a night and on a weekend you're going out on a binge, you may be damaging your liver a lot more than we thought before. fatty liver can caught hepatitis from alcohol. it can even cause cirrhosis or liver damage, lett of liver cells which -- death of liver cells. the liver is grand central station for the body. it metabolizes alcohol, gets rid of t

samadi, that sounds kind of frightening. >> it's actually acute study. it's a very small series coming from detroit. what the lead author wants you to know is that snoring is just not cosmetic or you don't get away with just kicking the person next to you and wake them up. it may have some health hazards, and the risks could be as bad as smoking for heart disease. the idea behind this is that when you snore, you would have a lot of vibration in your neck. that affects the vessels that goes to your brain and it increases the risk of stroke and heart disease. he's been able to back it up with carotid dopplers meaning that if you have any plaque in your neck, you can get a doppler and what they see is that there's thickening of the vessels on people that snore. what i get out of this is that number one, you need to get checked. it's not normal to have snoring. now, we're not talking about sleep apnea that we've spoken about in the past. we know that's a health hazard. this is without sleep apnea. go to a sleep center, get checked out, find out what's going

here to way is david samadi is member of the fox news "a" team and doctor, we should point out you areperts when it comes to prostate cancer and understanding how men can avoid it and prevent it and how to treat it. so what about this new study? >> it's a study that is coming from new england jumper of medicine. they looked over 3,000 patients and followed them for 15 years. what they are find ougtd there are some side effects with surgical treatment and radiation. most of these studies come from early mid '90s and we were doing a lot of open surgeries and radiation was not as sophisticated. we did all intense modular radiation they were. you have to take it with a grain of salt. i can tell you the answer to that question, there are certain times that treatment for prostate cancer we are overtreating it. there is overtreatment of prostate cancer is we don't have a real diagnostic tools. meaning that you may have many different types of prostate cancer, high risk, moderate risk or may have low risk. moderate risk and high risk you have to treat it because otherwise they will tie die. yo

david samadi of the medical a team.el any of these, get help starting with severe head pain, the worst headache of your life. >> this is very serious. a lot of people may have a migraine headache and it goes away. but if you have a throbbing headache like a belt around your head, you've got to see somebody. we were talking about a case where someone in my family ended up getting an m.r.i. and they found a tumor in the head. there is no room in the brain. it could be an aneurysm or a mass. don't dismiss that. severe headache that doesn't go away, go to the emergency room and make sure they investigate it. >>gretchen: what about a throbbing tooth? people say it is a little uncomfortable, i'll let it go for awhile. >> see your doctor. everything starts with the teeth being very sensitive when you drink something hot or cold. that's probably a crack in the enamel. then bacteria can get in and you can form an abscess. that is a big deal. by seeing a doctor early on you can save your tooth. and make sure you go in and not dis

david samadi is here to explain how lack of sleep is destroying america's health.or eight but even a little less is okay. >> i think ideally, six to seven hours is what you need. the importance of this is because you really need to get into the deep sleep or the rem sleep. that is when basically all the things you don't do during the day while you are sleeping body is going to repair and all the inflammation. so six to seven hours of sleep is ideal and try to get it. if you are getting up every two hours, that doesn't count. >> eric: so if you are like us us, you get five hours and you are at risk. >> big news is cardiovascular disease and a lot of studies are showing that if you get less than six hours of sleep you are at risk double. there is still reactive protein which is inflammation. it's heart disease and stroke is up. this is really important. over the years we've talked about diet. we've talked about exercise. eating healthy stuff. sleep is very important in preventing heart disease. >> eric: diabetes? >> if you have diabetes and not getting enough sleep,
