thank you, mr. reid. that's it for now. i'm paul gigot. hope to see you right here next week. so glad you could join us. joining us is dr. samadi. >> and dr. marc siegel, author of "the inner pulse," unlocking the code of happiness. he's joining us from sunny los angeles, getting that tan. good to see both of you docs. we're going to begin with the shocking details of the germanwings tragedy, the

co-pilot who deliberately brought down that plane was suffering from depression. dr. samadi, i want to start with you. how common is it for depression to get that extensive? >> well, it's an excellent question you're bringing up. look, there's about 350 people all over the world, in the globe suffering from depression. the question is, how many of them go far enough to be able to take the plane into the mountains? and it's important for people to recognize what are the signs and symptoms of depression. if anything comes out of this, working next to the guy that works with you, it's good to know what the symptoms are. if somebody has sleep disturbance, if they are not showing any kind of interest in usual daily activities, if their activity is down, energy level is down and, finally, when it all adds up, they become

suicid suicidal ideation is the big problem. they should get an exam every six months cht the issue with this, you know what this is? they go through the hearing and visual and all of this but they have no psychological evaluation. >> that's extreme. but i want to bring in dr. marc into this conversation. a lot of this, as we say from time to time, i'm depressed. really, dr. marc, how do you know that it's really serious, beyond feeling melancholy, where you have to actually get treatment? >> you may not know, arthel, or you may realize it and try to hide it. there's 50,000 pilots in the united states and canada. and i have to say, the vast majority of them are functioning at a very, very high level. i want our viewers to know we're talking depression today, we're talking depression in pilots, there's problems with some pilots even with substance abuse. there are issues to talk about

but the vast majority are doing thousands of hours a day safely. now, for physicians to screen and find depression, we're talking about 3,000 faa sanctioned doctors who do, as david mentioned, twice a year in pilots over 40, they are looking for general things. you know, is their appearance difference, do they community as well, are they sad? a lot of people in high-functioning jobs may not admit it. now, david has a related career. he's a top-level surgeon and has many, many years of training with people observing him actually, not under scrutiny but they can see the level of function that goes on. >> but dr. marc, i want you guys to bring the conversation back to the people at home. we understand this pilot was suffering from extreme depression to the point of being depressed and willing to kill 149 people. i want to talk, though, about the people here watching. dr. siegel, are there times in

your life when you may be more depressed than others? >> that's an excellent -- >> so breaking up with a girlfriend after a long relationship, a pilot who is going through prescriptions, knowing that his career is going to end, all of these attacks on him has brought him to the point saying enough is enough. there's a story about him, saying that one day i will make big enough name of myself and everybody will remember. guess what, we are remembering this. but this is a coward act of jeopardizing your life and 149 other people. >> how do you determine this? the girlfriend said that he was going to do something. apparently they broke up. the owner of lufthansa said that he passed the test. if somebody is really dangerous, what medication does work and how do we treat this seemingly growing scurge of -- >> you have to pay attention to

signs and symptoms. things that may not rook important to you, that's important. >> for example, like what? >> if somebody says, i'm tired, i've had enough, maybe i'll just take a chance. i just came from somebody who was a driver and says i had a rope around my neck and if my son would not have told me, what do i tell my son if you're going to kill yourself, that was enough for this guy to wake up. so pay attention to details. the other question that comes up, as a doctor, i know we have the hippa rules and as a doctor you don't break those rules because of privacy. if a doctor sees that a person is going to jeopardize other people, in those circumstances, the answer is yes. >> i actually agree with that. i was going to make that point, too. it has to doing with observing people's behavior and feeling if they are going to cross the line

of affecting our people's safety. 80 to 90% of the time depression is treated and it's treatable and i would say curable so that if someone is suffering from severe depression, they go on anti-depressive medications, 80 to 90% they can return to normal and function. we have to have an additional level of skrcrutiny and it's an illness and very common and easily treated. >> when a patient comes to you with these symptoms, what do you do? what do you suggest? >> i'm the front lines on this. i've got find out if there's changes in their relationships, that's number one that. may be true in this co-pilot here. did something happen? did you have a break-up? are you et getting along with

your family? i see how somebody relates to me. and then i think of therapy. do they neat cognitive therapy, if therapy is not working, medication. >> something prescribed by a doctor or -- >> it's something called the most commonly used antidepressant medication is something called an ssri, paxil, prozac, zoloft. as a primary care doctor, i can prescribe those but i have a very low threshold in et going the psychiatrist involved. >> but the psychiatrist has to know when to pull the plug when it becomes a real mass population jeopardy. i think what he had was a mild chronic depression that goes on for about two years because he had a history of this at the time when he left his training.

so just pay attention. but i think faa is going to look further into how to tighten up things on the planet. >> and beyond the faa, i think the whole country, i think we have to do a better job in this country and in america in dealing with the illness of a mental illness to help people. >> we should talk about it. it's okay to talk about it. >> that's a good point. it seems that it's taboo. talking about it is a very good start. >> go to your doctor and tell your doctor the truth and don't try to hide it. okay. getting a scrape is an uncomfortable experience but now there's a new type of therapy in the works that can make those little wounds heal a lot faster. not just band-aids and neosporin. that's coming up on "sunday housecall." i am totally blind. and sometimes i struggle to sleep at night, and stay awake during the day.

neosporin. we're back now with "sunday housecall." imagine cutting in half the time it takes for a wound to heal with a new type of therapy called nanotechnology. a fancy term. dr. siegel, what is it? if i get a wound, i kiss it and make it better and use like neosporin or something. >> if you kiss your wound, you're going to get more bacteria in it. but what you have to understand is that especially diabetics have a problem with wound healing and post-surgical, of course, we want our wounds to heal. it turns out there's an enzyme that stops your rescue workers from coming to heal the wound. it stops your white blood cells, it stops your immune system, it

stops the good skin from coming to form over. now scientists have figured out a genetic way to block that bad enzyme from forming and they take this treatment and package it up in nano particles, which means microscopic. it's a microscopic particle that gets right to the source of the wound and heals it. now, your next question which i anticipate, when is this going to be in the doctor's office -- sg. >> can i go down to cvs? >> it's past research and mice and pigs. but from pigs it will get to the human doctor's office a few years away. >> dr. samadi, what is it? is it a band-aid or something that you put on the skin? >> think about nanotechnology as something almost at the level of a cell. it's something you'd never be

able to see with the naked eye. it's a very, very hard field and for a lot of people who want to make money in the future -- >> we don't care about stocks and all of this stuff. we want to know what it is. >> do you go to a store and put it on your skin or -- >> it's a vehicle in the area that can bring more blood flow -- >> a cream or sauve or -- >> right now it's all investigation. right now it's a clinical trial. as marc said, it's been in nice and now going to pigs. it's going to deliver chemotherapy right at the cells. these are vehicles that can -- we can give you an injection and direct you to the areas where it has to go. so for chemotherapy and -- >> it will make the wound heal

faster with an injection? >> yes, basically it inhibits those cells that delay wound healing and by half. so this is all part of this study. >> okay. >> it's not there yet. not there yet. wait until we get it on the shelves. >> it's not going to be on the shelves. >> eric is always looking to are a quick fix. >> what did you say, doctor? >> it's in the movie hunger games but it's not ready for primetime. >> his boo boo is waiting. one viewer's question about possibly having too much potassium in her blood and the risks that go along with that. we'll talk about that afterer t break. before i had the shooting burning, pins-and-needles of diabetic nerve pain, these feet grew up in a family of boys... married my high school sweetheart... and pursued a degree in education.

but i couldn't bear my diabetic nerve pain any longer. so i talked to my doctor and she prescribed lyrica. nerve damage from diabetes causes diabetic nerve pain. lyrica is fda-approved to treat this pain. lyrica may cause serious allergic reactions or suicidal thoughts or actions. tell your doctor right away if you have these, new, or worsening depression, or unusual changes in mood or behavior. or swelling, trouble breathing, rash, hives, blisters, muscle pain with fever, tired feeling, or blurry vision. common side effects are dizziness, sleepiness, weight gain and swelling of hands, legs and feet. don't drink alcohol while taking lyrica. don't drive or use machinery until you know how lyrica affects you. those who have had a drug or alcohol problem may be more likely to misuse lyrica. now i have less diabetic nerve pain. and i love helping first graders put their best foot forward. ask your doctor about lyrica.

welcome back. time for our weekly segment about everything that worries us. this viewer asks, i'm a 68-year-old hispanic woman and my health has been good until last week that my blood work showed a high potassium level which shocked me. should i be worried? what happens to the body if it has too much potassium and how do you even check your potassium levels? >> the doctor draws the blood and it's responsible for the cell function and for the heart. if you have too much potassium, you're going to get arrhythmia and heart problems. i'd supervise the potassium. things like an adrenal problems

or herbs, believe it or not --h >> milkwood. there is a list of them over here which i will read to you. and but they need to know about this because this is important, and can increase this. >> while you look for that, let me ask dr. mark a question. >> dr. mark, something dr. siegel just said, there are a lot of people out there on die youretics because of high blood pressure. the pressure comes down but then they have to take potassium because it drains the body ofpy potassium. it is a sea saw way of controlling your body. again, how do you know if your potassium is too high? what does too much potassium do to the body. >> you made a great point, when you have high blood pressure we

tend to use agents that can bring your potassium up higher. i want you to understand the kidney is the filter. the kidney has to get rid of the potassium in the body. if it is impaired then you ends up backing up with too much potassium. or if the adrenal gland sim paired, both of those can lead to a heart arit meia where your heart can stop beating. i have to check for potassium, check for kidney function. if there is the slightest problem we will do an electrocardiogram and look for signs of hypotas yum. if i find it, i will do something dramatic to get that potassium down. a drug called k axo late, insulin, calcium. if necessary, i send the patient to the hospital which is the first order of priority in an emergency like that. >> dr. samadi, you mention herbs. >> siberian gin seng can

increase your potassium. or lilly of the valley. these are things people can use without knowing they are they can interfere with the potassium. always talk to your doctor about the herbs you are taking and the list of the medications. repeat your blood test first before you get excited into if you do take potassium and you get cramps in your plegs what's that a sign of. >> that interferes with some of the muscle activity and that's a sign that you have to talk to your doctor and lower that. dope take it on your own or over doing it. that's dangerous. >> i used to like bananas, get potassium from them. >> if you have any questions for your doctors, e-mail us, house call at fox news.com. we may answer it here on the air. all names and e-mail addresses are kept confidential. >> researchers are now warning pregnant women to be more careful about how much weight they put on before and during pregnancy. during pregnanananananan

janet? cough if you can hear me. don't even think about it. i took mucinex dm for my phlegmy cough. yeah...but what about mike? (cough!) it works on his cough too. mucinex dm relieves wet and dry coughs for 12 hours. let's end this. people ship all kinds of things. but what if that thing is a few hundred thousand doses of flu vaccine. that need to be kept at 41 degrees. while being shipped to a country where it's 90 degrees. in the shade. sound hard? yeah. does that mean people in laos shouldn't get their vaccine? we didn't think so. from figuring it out to getting it done, we're here to help.

back now to sunday house call. a new warning for pregnant women. researchers say those who are overweight before pregnancy or gain too much while pregnant are more likely to have obese

children, and those children are more likely to become obese as adults. dr. siegel, we know obesity is a widespread epidemic in our country. what does this study show? >> this is a double problem, eric, not just a sinkel problem. because i already can tell you that women that are pregnant that are obese have a huge problem in terms of complications, high blood pressure, diabetes, risk of preterm infants, risk of birth complications, actually. and this study at columbia looking at lower income women discovers that at the age of 7, their children are three times more likely to be obese. guess what that leads to? those obese children go on to become obese adults. they too end up with high blood pressure, with diabetes, high risks of heart attacks and stroke. and the journal of the american medical association reported in 2011 that we doctors are not even discussing weight with our patients. about half of the time i'm not -- me and doctors like me are not even saying, hey, you

are overweight. hey, you are obese. if you are going to have a baby, you better do something. >> well, they don't, i understand, and you've told me this before dr. samadi, the patients don't want to hear they are overweight. that's one thing. and i also want you to tell me how much should on average -- it differs for every women i'm sure, but how much is the average amount of weight a woman should gain. >> normally 25 to 30 pounds. if you are obese going into pregnancy, it's about 11 to 20 pounds. we always say if you catch obesity early on, i used to say age 2 or 4, then we can do something bk before they become diabetic or obese. now i'm going to change my mind. obesity and diabetes is actually starting from birth. and when someone goes into pregnancy they should prepare themselves and try to lose the weight. so this is a very important one. talking to the patients about their weight i think is important. there is a finesse and art of medicine to tell your parent how

to lose weight. but it can change someone's future in diabetes, heart disease, et cetera. so this is a very important study. >> dr., siegel, what is your best suggestion for losing weight and preventing the obesity epidemic. >> listen to what you just said. if people aren't listening it doesn't matter how much talking i'm doing to them. we have to get people to change their life-style. i personally believe exercise is where it starts. if you can do some exercise every day, even if it's just walking, ramp up to my favorite, the elliptical or the bike or some running. but some kind of cardioexercise every day and cut the bread out of your diet. my prescription for this we can, get rid of bread. >> i think genetics play as big role. there are people on tread mills all the time they are listening to this show, changing their dates but they have genetic problems. for those i think we need to get series help. but it does work. clearly, weight loss is the way to go. >> mediterranean diet, small

portions. >> the doctors love that. >> all right. thanks dr. mark. get back to new york. we're jealous that you are in l.a. thanks dr. samadi, that does it for us. >> thank you for watching "sunday housecall." we're here every sunday to make you healthy.s >> hello i'm eric shawn. welcome to america's news headquarters. >> topping the news this hour, a you are new push to end the chaos in yemen. the arab league creating a new military force against the iranian backed reball bell on. >> is the block backs revealing the final moments in the doomed german wings airliner. how the captain pleaded with the copilot to open the cockpit door. plus this. >> we are not going to change this law. it has beenes
