Why is there a bad taste in my mouth when I wake up in the morning?

The mouth is where we eat and is the starting organ of the digestive tract. Because all kinds of food are chewed in the mouth, the taste of food often remains in the mouth. Generally, people's mouths will have some taste after waking up. These smells may be emitted by the teeth and tongue. If we wake up in the morning and find that there is a rusty taste in our mouths, what is going on and what should we do?

Generally, the rusty taste in the mouth is caused by digestive tract diseases, such as gastritis or ulcers. You need to go to the hospital for a gastroscopy to confirm the diagnosis and further test whether there is a possibility of Helicobacter pylori infection. After the diagnosis is confirmed, symptomatic treatment is the main treatment, and spicy food stimulation should be avoided at ordinary times.

Gastritis is an inflammation of the gastric mucosa caused by various reasons and is one of the most common digestive system diseases. According to the urgency of clinical onset, gastritis can generally be divided into two types: acute and chronic gastritis; according to different causes, it can be divided into Helicobacter pylori-related gastritis, stress gastritis, autoimmune gastritis, etc. The pathological changes of gastritis caused by different causes are also different, usually including three processes: epithelial damage, mucosal inflammatory response and epithelial regeneration.

Acute gastritis can be divided into simple, erosive and hemorrhagic, corrosive, and suppurative gastritis according to its pathological changes. Chronic gastritis can be divided into three categories: non-atrophic, atrophic, and special types of gastritis according to its pathological changes. The diagnosis and differential diagnosis of various types of gastritis are mainly based on gastroscopy.

Peptic ulcer is a common digestive tract disease that can occur in the esophagus, stomach or duodenum. It can also occur near the gastrojejunal anastomosis or in the Meckel diverticulum containing gastric mucosa. Because gastric ulcer and duodenal ulcer are the most common, peptic ulcer generally refers to gastric ulcer and duodenal ulcer.

It is called peptic ulcer because it was previously believed that gastric ulcer and duodenal ulcer were caused by the digestion of the mucosa itself by gastric acid and pepsin. In fact, gastric acid and pepsin are only one of the main causes of ulcer formation, and there are other reasons that can cause peptic ulcer. Because the causes and clinical symptoms of gastric ulcers and duodenal ulcers have many similarities, it is sometimes difficult to distinguish between gastric ulcers and duodenal ulcers, so they are often diagnosed as peptic ulcers, or gastric and duodenal ulcers. If it can be confirmed that the ulcer is in the stomach or duodenum, it can be directly diagnosed as gastric ulcer or duodenal ulcer.
