Let's talk about something uncomfortable: gas and bloating. Most of us pass gas anywhere from 12 to 25 times a day, according to Brigham and Women's Hospital, and surveys show that abdominal bloating affects up to 30% of Americans. "Having a perfectly flat stomach all the time isn't normal," says Health contributing nutrition editor Cynthia Sass , MPH, RD. "After you eat and drink, food and liquids take up space inside your stomach and intestines, and that means some expansion."
A ballooned belly doesn't necessarily indicate that something is wrong with what you eat, but if your abdomen is too swollen to squeeze into your jeans, you may want to identify the belly bloaters in your diet.
The most commonly reported side effects were vomiting, loss of appetite, diarrhea, excessive salivation, agitation, tiredness, vocalization, confusion, increased water consumption, weight loss, weakness, fever, panting, and reversible changes in skin color (flushing or bright pink). Abnormal gait, seizures or tremors, as well as liver enzyme elevations, kidney failure, blood in urine and urine retention have been reported. In some cases death, including euthanasia has been reported. Sudden death was sometimes preceded by vocalization or collapse.
