Can cpap cause weight gain?

Postby jmt » Fri Jul 20, 2007 12:35 pm

I began using a cpap maching in February. At that time, I weighed 134 lbs. Not changing anything in my diet except for eating less carbs and smaller portions along with less snacking, I today weigh 145 lbs. In February I also started doing cardio dance classes 2-3 times per week at the YMCA. My weight gain is not being caused by gaining muscle as I am not strength training, and my abdomen is growing! (I am not pregnant)

I mentioned my weight gain to my sleep doctor a few months ago, and he said it's not related to using the cpap machine. I had my thyroid tested last week, and of course, everything came back normal.

I am very frustrated with the weight gain. I am 39 years old, and other than in pregnancies, have never had a problem maintaing my weight. Last night was my 3rd night in a row not using the cpap. I'm giving it up for at least a week to see if my weight goes down.

Has anyone else experienced unexplained weight gain while on a cpap machine?

Sleep apnea is associated with weight gain, but I don't believe that CPAP therapy has been associated with weight gain.

a cpap gives you more energy which perhaps could improve your apetite but no direct weight gain

It is untreated apnea that causes weight gain. But if you are willing to risk your health to drop ten pounds....then by all means have at it. Maybe it has to do with the fact that you are nearing your 40s and your metabolism is slowing down. I doubt it is because of the CPAP.

Most people have the opposite reaction....others have none at all.

I know someone on the forum reported that she normally slept through dinner and since CPAP found she didn't need to nap and sleep through the night, thus eating dinner each night and gained weight from that. To tell you the truth that happened to me too. When I was losing weight back a year and a half ago (two years?), there were nights I'd just hit the hay early and skip eating while I still felt full from a late lunch. Then I gained from staying up to eat dinner with my new girlfriend and back came the pounds.

I was snacking heavily before CPAP and after (since the machine wasn't at the right pressure for me). This past month I've been on a loaner APAP to see if I need a different pressure, and I have noticed a difference. Not only do I have more energy and am thus more physically active, but I don't have the gut gnawing hunger anymore, so my snacking has decresed considerably.
Like Jennmary said, untreated apnea can lead to weight gain.
However, having said that, no matter the no snacking and healthy diet changes (saying "I am on a diet" makes me want to reach for a candy bar...lol) I am still gaining weight. I don't know why...I have struggled with my weight all my life, but it's been fairly stable. I don't think it's a gain from treatment, seems to easy to blame that, but I sure don't have answers about it.

The only people I know of that gained weight from a cpap are those that ate the machine. It may be coincidental or due to other causes.

Generally swallowing the mask only is insufficient to explain weight gain.

You didn't eat your machine, did you? :-)

Cute John, and no, I haven't eaten my machine. I too, thought about getting a bit older being the cause. But, the gain seemed too coincindental. I did find something on the web about getting a cpcp tritations study done if you gain or lose 10+ lbs. It was vague though. I have a follow-up w/sleep dr. next month, and in the mean time I'll try not to eat my machine. :lol:

I gained weight prior to diagnosis of severe obstructive sleep apnea and my hopes and prayers are that I can enjoy more energy and be inspired to exercise and lose the weight but I found my stomach to been expanding since I started the CPAP machine 2 weeks ago. I know I have a newbie but my energy level has NOT increased yet either.

Last night I used the M series machine without the humidifier and slept okay but thought I should keep trying it because maybe the humidifier and the moisture from it may be causing my belly to grow.

Your thoughts and please, constructive help only, sarcasm helps no one and we all need life saving tips with this untreatable condition.

Thanks in advance for your input.

You may be having some bloating caused by air swallowing machelle. It can take several weeks or even months to feel the benefit of CPAP. Your body needs time to heal and rest.....after all it took a long time to get to this point.

I have been on CPAP almost 2 months....and I am finally seeing some of that energy and feeling alive again. Good luck .

Also gaining a lot of weight on CPAP.

The bloating wouldn't cause weight gain directly, because it is just air. But I got a CPAP last December, and after having maintained a regular weight my whole life, and through two preagnancies, I have gained 30 pounds in these last 6 months. My doctor does not believe me, but I KNOW it is CPAP related. I also know that it is due to what I'm eating, though. The first night I used the CPAP, I noticed that I woke up starving. Later I developed a problem with the CPAP blowing up my stomach to the point that my pants did not fit me anymore. In a weeks time, pants that were loose were not zipping. (No! I am not preagnant either!) Since no medical person will listen or believe me, I've had to come up with a theory myself. My theory is that the air is stretching out my stomach and making it bigger, so I feel hungrier. After all of the air comes out when I get up (which is not pleasant either,) I fill up the space with food. I have no idea what to do about this, but I do wish people who are not experiencing it themselves would not make snap judgements and say it's all in our heads. Not everyone is using the same pressure. Not everyone has the weakness of muscle that causes one to swallow air. I don't think you can tell someone they are not experiencing something because you didn't, or because you don't know everything. And if anyone is a doctor, please take note of the blown up stomach problem. Something will have to be done to remedy this some time.

Thank you for posting "guest". You used your words well and described exactly what I was feeling. Though most of you may not be gaining weight or suspecting a correlation to weight gain and cpap, you shouldn't try to make someone feel bad about their post. I was just looking for someone who was having similar experiences, but all I got were rude responses. Please don't bother responding if this hasn't happened to you, because you obviously can't relate.

Yes John-that was me. Seriously I have gained close to 40 lbs since starting on CPAP almost 2 years ago. My husband has dinner ready for me every night whereas preCPAP I was too tired to eat dinner.
I have completed my 6 required visits to my primary MD;see the bariatric surgeon on Aug.22;hoping to have my gastric bypass sometime in Oct.

CPAP weight gain

Postby machelle » Wed Jul 25, 2007 2:08 pm

I just spoke with my doctors office and I will be changing to "auto" titration but he is sure the CPAP is NOT related to my weight gain. Someone wrote about being so hungry, that's me too! Like I cannot get enough to eat since I started 2 weeks ago.

My belly is so bloated, I need help badly.

CPAP weight gain...I'm back with the following:

What Happens When You Stop Breathing During Sleep?
If you have sleep apnea, you stop breathing during sleep, and the balance of oxygen and carbon dioxide in the blood is upset. This imbalance stimulates the brain to restart the breathing process. The brain signals you to wake up so that the muscles of the tongue and throat can increase the size of the airway. Then, carbon dioxide can escape, and oxygen can enter the airway. These waking episodes are necessary to restart breathing (and to save your life), but you become sleep-deprived.

Sleep apnea has serious health consequences and can even be life-threatening. The main effects of sleep apnea are:

sleep deprivation, and
oxygen deprivation.
Sleep deprivation
Both the person with sleep apnea and the bed partner suffer from sleep deprivation. A bed partner may lose an hour or more of sleep each night from sleeping next to a person with sleep apnea.
Some trickle-down effects of sleep deprivation are:

Daytime sleepiness
A compromised immune system and slower healing
Poor mental and emotional health
Lack of smooth functioning of the body
Decreased productivity
A negative mood, irritability
Low energy
Unclear thinking, lack of concentration
Slower reaction time
Oxygen deprivation
Oxygen deprivation
When you stop breathing, your brain does not get enough oxygen. Drastic problems can result from the oxygen deprivation of sleep apnea:

Insomnia, restless sleep
Heart disease, heart failure, or heart abnormalities such as arrhythmia (irregular heart beat)
Stroke, high blood pressure (hypertension), and other cardiovascular system problems
Type II diabetes
Memory problems, learning difficulties, and lack of attention
Rapid weight gain and obesity
Impotence, sexual dysfunction, or reduced libido
Morning headaches
Depression
Sevenfold increase in involvement in auto accidents
Premature death, such as Sudden Infant Death Syndrome (SIDS)
Other, more mild effects of sleep apnea
Some other consequences of sleep apnea are:

Frequent bathroom visits to urinate during the night
Heartburn
Excessive sweating during sleep
Dry mouth in the morning
Loud snoring
In children, a concave chest during sleep
