There the digestion continues. But the stomach does not always work as it is supposed to. Functional dyspepsia is a chronic condition with symptoms that about one third of people worldwide experience. Whenever they eat too much, too much fatty food or too late in the evening, they suffer from stomach pain, a sensation of fullness and heartburn. Nicotine and caffeine make the symptoms worse.
