Still eating healthy intake and excercising trying to lose weight to get rid of apnea if its even the cause. should i avoid pushups for weight loss?

Exercise: Good job on healthy diet and exercise to lose weight! that is the most important component of treatment of sleep apnea. Burning calories with cardio exercise such as running, swimming, rowing, stairmaster, dance class, biking are all excellent options. Pushups are ok, but are more for upper body strengthening rather than weight loss.

Keep going: You are on the right path. Keep working on weight loss. I'd encourage any and all exercise, including push ups. Strength training results in increased muscle mass, which does help in burning fat. Weight loss does help improve obstructive sleep apnea and many other things like hypertension and diabetes. Way to go and keep it up!
