Ask the Sleep Doctor - Bariatric Surgery, Narcolepsy Medications

Sleep doctor ready to answer questions


Dear Dr. Rosenberg,

I am very obese and have severe sleep apnea. I am contemplating bariatric surgery. Can you give me some idea as to whether the surgery might cure my sleep apnea?


That is a great question. Most studies show that about 60% of those who undergo bariatric surgery no longer need CPAP devices for sleep apnea when they achieve their target weight.

Dear Dr. Rosenberg,

My 18-year-old daughter was recently diagnosed with narcolepsy. The medication she takes to help her stay awake is Adderall. However, it makes her very anxious and is not helping with her cataplexy. She still gets very weak if she laughs or gets angry. Any ideas?


Yes. First, I hope she is seeing someone who specializes in sleep medicine. Adderall would not be my first choice to help her stay awake. It is an amphetamine derivative and can cause anxiety in some people. The drugs Provigil and Nuvigil would probably be preferable. As for her cataplexy, neither of these medications address that problem. There are several options to treat cataplexy including some of the antidepressants, as well as a medication called Xyrem. I would address these concerns with her healthcare provider and if not, request a referral for a specialist in narcolepsy.

Dear Dr. Rosenberg,

Is there any value to taking magnesium for sleep? I've had trouble falling and staying asleep for several years and friends have told me magnesium helps.


Yes, there is some benefit. Several studies have shown that as we age, our magnesium levels fall. This is in part due to decreased bone mass and dietary intake. Magnesium plays a role in decreasing the ability of the stimulating neurotransmitter glutamate to activate areas of the brain that would keep us awake. At the same time, it facilitates the action of GABA A receptors that promote sleep and decrease anxiety. It has also been found to increase deep slow wave sleep and decrease nighttime cortisol levels. Dietary sources include nuts, whole grains, green leafy vegetables, seeds, and seafood. However, for most of my patients I suggest a supplement with 250 to 400mg of magnesium before bedtime.

Dear Dr. Rosenberg,

My son sleeps about six hours a night. He is 15 and is on his computer and cellphone until very late. He has put on 60 lbs. in the last year. Can this be related to his sleep?


Yes, most definitely. We know that teenagers his age should be getting 8 to 10 hours of sleep. When they don't, the body responds by putting out excessive amounts of the appetite-stimulating hormone Ghrelin and insufficient amounts of the appetite-suppressing hormone Leptin. Thus, obesity is very common in teens who do not get enough sleep. I hope you share this information with your son and get him to turn off those sleep-preventing blue light emitting electronics devices.

  1. Hello doctor
    I have narcolepsy and cataplexy I am about 50 pounds overweight would getting a Gastric sleeve to lose weight help my symptoms? And would it cover with hmo insurance?

  2. I had bariatric sleeve surgery 16 months ago and have had awake bruxism ever since. I'm looking for a solution to this. Any ideas?

  3. Dear Dr Rosenberg
    What do yo think about a patient with narcolepsy type 1, obese (BMI 40), metabolic syndrome (Hypertension, Dyslipidemia) and OSA (Using CPAP), have an sleeve gastrectomy?
    Would you recommended or contraindicated?
    What perioperative measures would increase safety and quality care for these patients?

  4. Hi my name is Christine I am 53 years old I had a gastric bypass about 15 years ago. I also suffer from sever depression,bipolar disorder and the worst of them all a sever compulsive disorder and just these last couple of years narcolepsy. Because of the gastric bypass surgery my medication is absorbing in a way that requires Me to take more than the average person.i don't know what kind of doctor would specialize in helping all that is wrong. Please help me.



    1. Yes, I would suggest you consult with a sleep specialist. What you are describing is sleep paralysis associated with hallucinations. It is the overlapping of REM sleep into wakefulness, which can be a symptom of narcolepsy. It is also seen with increasing frequency in untreated sleep apnea, anxiety disorders, and when we are not getting enough sleep. In most people, there is no cause. However, with your history of epilepsy, as well as the frequency with which these episodes are occurring, I think a consultation with a board certified sleep specialist is a good idea.

  6. I grind my teeth at night - which gives me constant daytime migraines. I have tried lots of different nigth guards to no avail. It has been suggested I try nose clips so I will therefore breathe through my mouth hopefully the with my mouth open I will not be able to grind. I did try a clothes line peg which actually seemed to work but longterm I want to find a proper nose clip. What is your advice please. I am desperate. THanks Louise.

    1. What you are describing is called sleep bruxism. It can be due to many reasons. These include hereditary, anxiety, excessive caffeine, smoking, and alcohol. Even some antidepressants and sleep apnea may be the cause. As for the nose clip idea, I doubt that will do anything for you. There are numerous therapies including dental splints, medications, relaxation techniques, hypnotherapy, biofeedback, as well as treating sleep apnea if existing. At this point, I would recommend you see a board certified sleep specialist, as you have not responded to a dental device.
