Digestive tract diseases

There are many classifications of digestive tract diseases. Because the digestive tract contains many organs, if diseases occur in these organs, milder cases may be cured quickly. However, if it is a serious digestive tract disease, such as food poisoning, it will cause people to suffer from vomiting, diarrhea, dizziness and nausea, and in severe cases it may even lead to death. So when it comes to diseases of the digestive tract, they can be said to be serious, but they can also be said to be not serious. The situation varies from person to person.

In the summer when the temperature is generally high, if the vegetables and fruits people eat contain some residual viruses and are not cleaned up, it will also add a lot of burden to the stomach and intestines. Moreover, high temperature is a season suitable for the growth of bacteria. Therefore, eating in many open-air places may cause gastrointestinal discomfort. Therefore, I hope everyone will pay attention to whether the place where they eat is clean.

General inflammatory gastrointestinal diseases

1. Acute gastritis

Acute gastritis is an acute inflammation of the gastric mucosa caused by different causes. Severe lesions may involve the submucosal layer and muscular layer, and even reach deep into the serosa. Clinically, it is divided into acute simple gastritis, acute erosive gastritis, acute corrosive gastritis, and acute suppurative gastritis according to the different causes and pathological changes. Among them, acute simple gastritis is the most common clinically, while acute suppurative gastritis has become rare due to the widespread use of antibiotics. There are many factors that lead to the disease, including chemical or physical stimulation, as well as bacteria or their toxins. Chemical irritation mainly comes from spirits, strong tea, coffee, spices and drugs (such as salicylate preparations, indomethacin, phenylbutazone, glucocorticoids, etc.). Among them, acute corrosive gastritis is mostly caused by swallowing strong acids, strong alkalis and other corrosive agents. Physical stimulation such as overheating, overcooling, overly rough food and X-ray radiation can damage the gastric mucosa and cause inflammatory changes. Eating food contaminated by bacteria or their toxins is the most common cause of acute gastritis.

Symptoms are mild, with only abdominal pain, nausea, vomiting, and indigestion; severe cases may include vomiting blood, black stools, and even dehydration, as well as poisoning and shock.

2. Chronic gastritis

Chronic gastritis refers to various chronic inflammatory lesions of the gastric mucosa caused by different causes. It is a common disease and one of the frequently-occurring diseases in the military. Its incidence rate ranks first among various stomach diseases. Since the widespread use of fiber endoscopy, the understanding of this disease has been significantly improved. Chronic gastritis often has a certain degree of atrophy (loss of mucosal function) and metaplasia, often involving the cardia, accompanied by loss of G cells and decreased gastrin secretion, and may also involve the body of the stomach, accompanied by loss of acid-secreting glands, leading to a decrease in gastric acid, pepsin and intrinsic factors.

Chronic gastritis lacks specific symptoms, and the severity of the symptoms is not consistent with the degree of gastric mucosal lesions. Most patients are often asymptomatic or have varying degrees of indigestion symptoms such as upper abdominal pain, loss of appetite, fullness after meals, acid reflux, etc. Patients with atrophic gastritis may have anemia, emaciation, glossitis, diarrhea, etc. Some patients with mucosal erosion have obvious upper abdominal pain and may have bleeding.

Upper abdominal pain, indigestion, hematemesis, black stools. Common symptoms include recurrent, irregular abdominal pain, pain that often occurs during or after meals and is mostly located in the upper abdomen, around the navel, and in some children the pain is not fixed. Mild cases may be intermittent dull pain or dull pain, while severe cases may be severe colic. It is often accompanied by loss of appetite, nausea, vomiting, and abdominal distension, which continue to affect nutritional status and growth and development. Patients with gastric mucosal erosion and bleeding are accompanied by vomiting blood and black stools.

The above are just some common symptoms of gastritis. For some people, the stomach pain is almost life-threatening. However, some people also suffer from stomach discomfort due to irregular eating habits. Eating too much or too little can cause stomach discomfort. Therefore, we should take good care of our stomach, otherwise it would be very uncomfortable if we suffer from diseases such as gastritis.
