Patient discussion about bloat

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.

Not surprisingly, certain breeds were found to be at high risk for bloat, particularly large or giant breeds.
Also according to the Purdue study, the risk of bloat was more than twice as high in dogs seven to 10 years old compared to dogs two to four years old, and more than three times as high in dogs age 10 and older.
And if you get to the vet in time, the odds are with you: In a retrospective study of 166 cases between 1992 and 2003, researchers found that short-term mortality resulting from bloat surgery was a relatively low 16.
Securing the bottom of the stomach to the right side of the body so it cannot rotate during an episode of bloat is the common goal of each type of surgery, but slightly different methods are used to accomplish this.
Glickman has been quoted as saying that the risk of bloat and torsion after the procedure is less than five percent--not bad odds at all.
In the end, the question of whether or not to have a gastropexy done is arguably tougher for those whose dogs who are not at very high risk: The owner of a Great Dane has a greater incentive for getting a gastropexy than, say, the owner of a Shih Tzu, whose bloat rates are not as comparably high.
A 2003 study that looked at the benefits of prophylactic gastropexy for atrisk dogs used a financial metric to assess the benefits of surgery: Working under the assumption that elective gastropexy surgeries cost about $400 and emergency bloat surgeries cost at least $1,500--or as much as four times that--the study concluded that the procedure was cost effective when the lifetime risk of bloat with torsion was greater than or equal to 34 percent.
Mixed breeds, particularly those with chests that are deep and narrow, are also at higher risk of bloat.
In some cases restricting access to as little as 10 minutes a day at the start may be necessary to prevent bloat,' says Mr Laven.
