Patient discussion about meteorism

Q. why do i have gas and bloating my bowels are weird and my stomach is sour also. i have pain in the top of my stomach

A. There are many different things that can cause them. Do you also suffer from diarrhea? Do you have diabetes? Do you have pain that is relieved by eating or after going to the bathroom?

Among the more common causes there are IBS (, diabetes, malabsorption (e.g. lactose intolerance or celiac, all of these, unfortunately, can't be diagnosed over the net, so if it keeps bothering you or if you have warning sign (such as Nocturnal abdominal pain (sleep awakening), Weight loss, Blood in the stool , Severely tender abdomen , Succussion splash , Fever , Vomiting , fatty diarrhea , New onset diarrhea) you should see a doctor.

Q. Why am I feeling so bloated all the time? I did a pregnancy test 2 weeks ago and it came out negative, i have been experiencing a bunch of symptoms that relate to pregnancy and the spotting on and off has started wondering if i should do another test and see what comes out of it..

A. Home pregnancy tests are not 100% accurate. Either because their own limitations or because limitation of the use of them (e.g. testing too early, misunderstanding the instructions etc.). You may try to do the pregnancy test again and see the results now. Anyway, even if you receive positive results in the second test, it should be validated by a test performed by a doctor.
