Hi There, Thanks for asking. Stop breathing is an important issue in medicine. It is observed by another person and shallow breathing
is also another sign which usually accompanies it. Upper middle pain in stomach is because of positive pressure induced by lack of good ventilation at night and chest pain
could be because of lack of good oxygenation at nights. These are symptoms of sleep apnea
. Weight loss
can help for improving it specially if you want to prevent it from worsening. You need to lose at least 10 to 15 pounds to see its effects on your breathing. Let me know if you have any other question.
