What causes stomach upset, dizziness and nausea?

In life, some patients with stomach problems may experience some particularly uncomfortable symptoms, such as stomach discomfort, dizziness, nausea, etc. Most of these symptoms are caused by some stomach diseases. For the treatment of the disease, the first thing to do is to discover it in time.

Gastritis refers to inflammatory changes in the gastric mucosa caused by various factors. It is particularly common among people with irregular diet and work and rest schedules. According to the course of the disease, it is divided into acute and chronic types, and chronic is more common.

Including acute gastritis (acute suppurative gastritis, acute erosive gastritis, acute simple gastritis, acute corrosive gastritis), chronic gastritis (chronic superficial gastritis, atrophic gastritis, chronic erosive gastritis), postoperative reflux gastritis, bile reflux gastritis, refrigerator gastritis, giant hypertrophic gastritis, etc.

It can be caused by chemical factors, physical factors, microbial infection or bacterial toxins. In addition, mental and neurological dysfunction, stress state or allergic reactions caused by various factors can all serve as endogenous stimuli, causing acute inflammatory damage to the gastric mucosa.

Symptoms and signs

1. Acute gastritis develops suddenly. Mild cases only have loss of appetite, abdominal pain, nausea, and vomiting. Severe cases may cause vomiting of blood, black stools, dehydration, electrolyte and acid-base imbalance, and those with bacterial infection are often accompanied by symptoms of systemic poisoning.

2. Chronic gastritis lacks specific symptoms, and the severity of the symptoms is not consistent with the degree of gastric mucosal lesions. Most patients often have no obvious symptoms or have varying degrees of indigestion symptoms, such as upper abdominal pain, loss of appetite, fullness after meals, acid reflux, etc.

3. Patients with atrophic gastritis may have symptoms such as anemia, weight loss, glossitis, diarrhea, etc. Some patients with mucosal erosion may have obvious upper abdominal pain and may have bleeding.

What causes stomach discomfort, nausea and vomiting? When the doctor diagnoses that the physical discomfort is caused by gastritis, it can be directly controlled with medication. If the patient has a strong tolerance and good physical resistance, reasonable food can regulate his gastritis. When the patient feels unwell, he should control the food intake and stay away from raw and cold foods that easily breed bacteria. Each meal should be taken at a normal time and the type of food should be lighter.
