hi,
thank you for your query.
Yawning can signal lack of
oxygen in the bloodstream.
Tiredness, whereby one doesn't breathe deeply or properly, can cause yawning. But, it can also signal deeper physiological causes such as lack of red blood cells, a weak heart or poor lung health.
the common causes include-
1.panic attacks/
anxiety are the most common cause.
2.anemia
3.lung infections,disorders
3.heart ailments
i would suggest you to get a
complete blood count done.it will show the number of red blood cells and also if there is any infection in the body.
in either case treatment can be started.
in case of anemia symptoms will reduce in 2 months.
for panic attacks,she needs
counselling and support
thank you,
you can contact me for further queries.
