Indigestion is often encountered in our daily life, and if we do not pay attention to our diet, we can easily suffer from indigestion, which brings a lot of inconvenience to people’s life. What is indigestion? Indigestion generally refers to functional indigestion, with epigastric pain, epigastric distension, early satiety, belching, loss of appetite, nausea, vomiting and other uncomfortable symptoms, after examination to exclude the above symptoms caused by organic diseases of a group of clinical syndrome. Symptoms may be persistent or recurrent, with a duration of more than one month or accumulated over twelve weeks in the past December. Causes of indigestion? Overeating, eating excessively greasy food, drinking too much alcohol, irregular work and rest, mental stress, and frequent use of painkillers or aspirin may all lead to indigestion. In addition, many digestive system diseases have symptoms of indigestion, such as chronic gastritis, gastric and duodenal ulcers, chronic hepatitis, cholecystitis, chronic pancreatitis, etc. can lead to indigestion. Therefore, when patients have indigestion, first of all, we need to clarify what the cause of their indigestion is, whether it is organic or functional, and need to check and diagnose clearly before treating the cause and prescribe the right medicine. Do I need to take medicine for functional indigestion? Because common stomach problems may have symptoms of upper abdominal pain, upper abdominal distension, early satiety, and loss of appetite, which are similar to those of functional dyspepsia, families usually turn to the gastrointestinal medicine they always have at home to eat, but in fact, the causes of the two are completely different. The causes of stomach discomfort are: Helicobacter pylori, excessive secretion of gastric acid, tumors, irritating food, mental stimulation, drug damage, etc. Functional dyspepsia is not an organic disease, and various seemingly insignificant factors, such as eating too much and too greasy, smoking and alcohol abuse, may lead to dyspepsia. In addition, mental stress is an important reason for the aggravation of functional dyspepsia, such as high work pressure, changes in work and life environment, etc. can easily lead to a series of abdominal distension, indigestion, poor appetite feeling. Generally speaking, if the diagnosis of functional dyspepsia, there is no need to worry excessively, just like the flu happens to healthy people, the vast majority of them can be cured without treatment. Symptoms that were not very serious, some patients think they are very serious, and then they will have a lot of worries, thus they are easily misled by some false advertisements. Therefore, if you have symptoms of indigestion, you should first visit a proper hospital to rule out the possibility of organic diseases causing indigestion, and do not take medicine on your own. In addition, although the occasional one or two indigestion does not have any effect on human health, but long-term indigestion symptoms will affect life and work, or need to seek medical help to cope with.
