What I wanted to know is what would be in the airway and are most people with sleep apnea overweight (not from the sleep apnea).
j n k said:"Obstructive" means it is something physical in the upper airway. And yes, sleep apnea can cause someone to be overweight.
This will explain:

Which came first?......The chicken......or the egg? That is the question that passes through my mind everytime I hear, read, or discuss the apnea vs weight issue. I have read the studies. I agree that anatomy induced apnea can lead to being overweight. It is obvious that bad sleep can do the same. There are alot of people in this country that are overweight because of laziness and improper diet. A huge majority of these people also have apnea. I think it is to easy to blame apnea as a global reason for obesity. While apnea may cause a % of its victims to be overweight. The % of people who have apnea because they are overweight has got to be far larger then the latter. We are all susceptable to apnea. With every percent we add to our BMI after 30% we increase not only the chance of apnea, but of any high risk health issue. ie; cancer, Heart disease.
Is it apnea, or a lack of deep sleep(stage 3, REM) that causes people to eat more? Lack of deep sleep is a symptom of apnea. It is also a symptom of bad sleep hygiene, or insomnia. A person that has a bad sleep schedule for years is just as likely to be overweight as a person whom has had apnea for years. More so in my opinion depending on AHI. A person with an unsymptomatic moderate AHI, or lower, might get better sleep than someone that consistantly short changes their sleep cycles everynight. I believe that living an unhealthy lifestyle is the largest determining factor in when a person will get apnea. Without a trach we will all get apnea. Whether or not it is at 30 or 70 is greatly affected by the lifestyle you choose to live. Blaiming obesity on apnea is to easy.
An even better question would be what effect does a lack of sleep have on compulsive disorders? Sleep deprivation is a part of my life. I see it, live it, and fix it. A great deal of my patients have compulsive disorders. Drinking, eating, drugs I have seen it all in my time in the lab. i had a woman the other night eat 4 cupcakes with no recollection in the morning. Pts come in all of the time with alcohol on their breath, or high on something. When I do not sleep I turn into a clean freak. No clutter UGH!! When I have plenty of sleep I could care less. Mr Laid Back. Obsessive compulsion and irrationality are definately symptoms of bad sleep. This mixed with a slow reaction time could make for a really stressful day. This same mix, and stress, could also be what is driving the tired to eat, drink, or do drugs.

I did not say that it couldn't jnk. I actually agreed with that fact. i think that more people have apnea because they are overweight than people who are overweight because they have apnea. I also do not know if I agree that it is the apnea causing people to be overweight over the lack of deep sleep being the cause.

It is not the apnea, it is the lack of.................REM sleep that causes the weight gain.

SLEEP PROBLEMS MAY BE CAUSING YOUR WEIGHT GAIN
New Orleans, LA (June 21, 1998) - A study presented at the 12th Annual Meeting of the Associated Professional Sleep Societies in New Orleans, Louisiana, suggests that there may be an important link between weight gain and sleep.
Researchers at the University of Southern Mississippi studied 163 patients with obstructive sleep apnea (OSA), a commonly occurring sleep disorder that involves frequent and long pauses in breathing during sleep that can lead to severely disturbed sleep, to see if decreased REM sleep (a period of intense brain activity and suppressed muscle activity during sleep) is related to obesity in OSA patients.
The study's principal investigator, Jennifer Peszka, noted, "Sleep researchers have known for some time that there is a strong association between OSA and obesity. Approximately 80% of OSA patients weigh 130% or more of their ideal body weight, and substantial weight gain may occur in the year prior to OSA diagnosis. It is likely that weight gain leads to or worsens OSA. It may also be that OSA leads to weight gain and obesity."
Peszka and her colleagues built upon this knowledge by identifying factors that may lead to this vicious cycle. The first factor that they identified was excessive daytime sleepiness and fatigue, which may lead to decreased physical activity and thereby result in weight gain. The second factor the researchers identified was decreased REM sleep. According to Peszka, decreased amounts of REM sleep stage may lead to increased food intake.
The team of researchers from the University of Southern Mississippi specifically examined this second factor. Peszka noted, "The hypothalamus, a part of the brain involved in many motivated behaviors, may be the link between eating and sleeping. Animal studies have shown evidence for this relationship; however, so far there is very little evidence in humans."
To investigate the possibility that decreased REM sleep is related to obesity in sleep apnea patients, researchers examined the relationship between a patient's weight and a common treatment of OSA, nasal continuous positive airway pressure (nCPAP), using 163 patients from Forrest General Hospital's Sleep Disorders Center in Hattiesburg, Mississippi. The researchers' model predicted that patients with the least REM sleep would weigh the most before treatment began, and would show the greatest weight loss with successful nCPAP treatment.
Peszka and her colleagues found evidence to support these predictions. OSA patients with the smallest amount of REM sleep were almost 20 lbs heavier than other patients at the time of diagnosis, and patients with the biggest increase in REM sleep following treatment showed the greatest weight loss at follow-up.
Peszka noted, "This study suggests that decreased REM sleep associated with OSA is a significant contributor to obesity, and that weight loss is possible for some patients using nCPAP." The finding is particularly important since OSA patients can suffer from excessive daytime sleepiness, decreased quality of life, and increased likelihood of heart attack, stroke, hypertension, and other disorders.
Furthermore, this relationship may have broader implications, according to Peszka. A decrease in REM sleep could also lead to weight gain in other circumstances associated with shortened sleep, such as shift work and lifestyle choices.

lack of sleep linked to weight gain in new moms.
http://www.womenfitness.net/sleepformoms.htm
Sleep is essential. It is the time when our bodies replenish, repairing the mental and physical wear-and-tear we suffer during the day. However, our "always-on" culture has created a sleep-deprived generation. Cell phones, computers, PDAs and 24-hour cable television keep our brains stimulated. The result is fatigue, poor health and, surprisingly, weight gain.
According to a study conducted by Kaiser Permanete and Harvard Medical School/Harvard Pilgrim Health Care, it was found that moms who got less than five hours of sleep a day when their babies were 6 months old were three times more likely to be carrying 11 extra pounds at the child's first birthday than those who get seven hours. The bottom line –- those extra two hours of sleep could make all the difference

Insomnia and Weight Gain
A new study examines the link between insomnia and weight gain.
The study involved 14 men with primary insomnia and 24 healthy controls. It measured their levels of the “hunger hormones” leptin and ghrelin three times during one night of sleep.
Results show that men with insomnia had less total sleep time than controls. Leptin levels were similar between the two groups. Leptin helps to suppress your appetite and increase your metabolism.
But ghrelin levels were about 30 percent lower in men with insomnia. Ghrelin stimulates appetite.
So it would seem that insomnia lowers your risk of weight gain. Less ghrelin means you would be less hungry.
But this may not be the case. Lead author Sarosh Motivala of UCLA thinks that a change may occur during the day to increase appetite. Other studies show that sleep loss decreases leptin and increases ghrelin.
What is clear is that insomnia disrupts how the body regulates appetite.
"The current study shows that insomnia patients have a dysregulation in energy balance that could explain why these patients gain weight over time," Motivala said in a UCLA statement. “"This is an exciting finding because it highlights how diverse behaviors like sleep and eating are connected.”
Most people with insomnia have “secondary” insomnia. It occurs along with another medical problem, mental illness or sleep disorder. It also may result from the use of a medication or substance.
The men in this study had “primary insomnia.” This kind of insomnia is unrelated to another health problem. It is estimated that about 25 percent of people with insomnia have primary insomnia.
A 2008 study in the journal Sleep linked primary insomnia to low levels of a brain chemical. Results show that GABA levels are reduced by 30 percent in adults with chronic primary insomnia.

jnk you are right apnea does cause weight loss. As will any sleep disorder or drug that causes a suprression of deep sleep, or specifically REM sleep. I believe that this same lack of deep sleep also causes aging. We can not diminish the fact that apnea has 2 distinctive effects. One is stacking and the other immediate. O2 deprivation of apnea can be insignificant for some time. By definition an apnea does not need a desaturation to be an apnea. This is because regardless of o2 desat or not it is still going to effect your sleep. The effects of bad sleep can be seen in a couple of days. Within weeks it can be overwhelming.
