American football, referred to as football in the United States and Canada, and also known as gridiron football or simply gridiron, is a sport played by two teams of eleven players on a rectangular field with goalposts at each end.
Flatulence, or gas, is actually a normal bodily function and, in fact, it is quite healthy. Flatulence is the by-product of digestion, although when cancer treatment causes severe flatulence and/or lower abdominal pain, measures can be taken to minimize the treatment's effects.
Food poisoning can cause abdominal pain, diarrhea, nausea, vomiting, fever, chills, and weakness. Belching or passing gas clears gas from the digestive tract, but when gas is stuck it causes abdominal pain. Some heart rhythm disorders can cause a fluttering in the chest, shortness of breath, chest pain or dizziness. Peptic ulcers, sores in the lining of the stomach or upper intestine, cause abdominal pain, gas, and more. Pleurisy, an inflammation of the lining of the lungs and chest, causes sharp pain when you breathe.
