Hi welcome to Health care magic forum. Every morning you after breakfast if you go out you will have nausea
, if you stay at home you don't feel any thing. Probably it is obsessive compulsive neurosis
. it is effective in some ocasions, where your inner mind don't like such place. So it shows it in different forms in different people where there is tendency for that thing. say nausea in your case, because you are week in stomach functions.
I advise you to consult a physician for diagnosis and treatment, you may need to have gastroscopy done besides other routine tests for confermmation .
Besides i advise you some diet recommendations as avoid taking more of spices, chillies, junk foods and oily foods, to avoid indigestion
Take more of green leafy vegetables, pulses, sprouts, milk,egg, meat, fleshy fruits, and dry fruits. they will increase blood, general health , resintence, and stamina to tackle such situations. Wishing for a quick recovery and thanks for calling.
