Does obesity cause sleep apnea?

Not just weight. Anatomy is king. Obstructive sleep apnea happens in a small airway "box". The airway can be small if what's in it takes up space or if the box is smaller. Weight gain increases tongue size and the thickness of the side walls of the throat. Tonsils may be large. Small jaw size, often inherited , will increase the risk of osa . Low muscle tone is also a factor.
Yes. Obesity can cause obstructive sleep apnea (osa). A person with osa may not have enough space in the throat area, so air can't flow easily to the lungs during sleep. An obese person has more fat, including in the neck and throat areas, so there is more flesh to block air flow. An obese person lying down has extra weight in the tummy pushing up at the bottom of the chest, making breathing more work.

Closing the airway. Obesity and particularly central adiposity are potent risk factors for sleep apnea. They can increase pharyngeal collapsibility through mechanical effects on pharyngeal soft tissues and lung volume, and through central nervous system–acting signaling proteins (adipokines) that may affect airway neuromuscular control.

Quite a bit. Obesity is one of the main causes of sleep apnea. The tissues in the throad aree compromised and the neck muscle diameter becomes too large and can actually shut down the breathing airway apparatus. See a doctor and consider your overall health. Read more...

Morbidly obese w/ treated sleep apnea. No CardioV disease other than high bp/cholest. Will losing weight remove fat around the heart, unclog arteries?

Yes. Weight loss can reverse fat deposits both under the skin and in/around the vital organs. Be sure to eat lots of fruits and veggies. Eat healthy fats like salmon, nuts, seeds, olive oil, avocado, etc. Increase protein, especially lean and plant based proteins. Skip soda, processed foods, highly refined carbs & restrict sugar. Ask your doctor if weight loss surgery is appropriate. Read more...

Can obesity lead to swelling in legs and feet al had echo cariagram and stress test came back ok I have severe obstructive sleep apnea if I loose we9?

Do lose weight! Losing weight will certainly help both your swelling and the sleep apnea! Will it cure both? Depends on whether or not something else is causing either or both. But both will improve with weight loss (usually!) and you will certainly be healthier if you lose weight. Go for it! (High protein-low carb diets are not the way to go for most, these are causing their own set of med. problems.) Read more...

Is continuous diffulty in swallowing be a sign of sleep apnea. I have poor sleep and wake up with sore throat. MD dismissed sleep apnea as iam not obese?

See an ENT. Swallowing difficulty is not a typical sign of sleep apnea, but can be related to other problems that may affect your sleep (like very large tonsils, for example). This should be evaluated by an ENT. Throat could be sore because of dryness and irritation from mouth-breathing/snoring, sinus drainage, or acid reflux. If your nose is obstructed (e.g. deviated septum), this can worsen mouth breathing. Read more...
