The food you eat is not fully digested and absorbed in the stomach, and constipation or diarrhea may easily occur.

Because it will lead to poor absorption of nutrients by the human body, it is easy to develop iron deficiency and cause iron deficiency anemia, especially for minors and pregnant women, who have a high demand for iron.

Because food is not well digested and absorbed in the human body, it is easy to ferment in the gastrointestinal tract to produce toxins, so it is easy to get acne.

Due to poor absorption, resulting in a lack of mineral elements in the body, the nails on the human limbs are easily damaged.

Because food ferments in the gastrointestinal tract, these people often feel bloated.

The so-called hypochlorhydria means that there is a lack of hydrochloric acid in the stomach, that is, insufficient secretion of gastric juice. It is unable to carry out the work of digestion and antiseptic fermentation, which affects the digestion and absorption function. Therefore, it is easy to suffer from gastrointestinal diseases and can also lead to Disorders in the digestion and absorption of nutrients. Many minerals and vitamins require adequate concentrations of stomach acid for optimal absorption - iron, zinc and B vitamins are examples. Patients with achlorhydria or insufficient gastric acid may suffer from a variety of nutritional deficiencies, which can lead to many health problems and greatly affect people's health.

Hypochlorhydria is more common in chronic atrophic gastritis, and is often characterized by upper abdominal discomfort, anorexia, and indigestion.

The main symptoms of hypochlorhydria are gastric indigestion, burping and chest burning pain. Low gastric acid concentration in gastric juice may be caused by pernicious anemia, tropical fatty dysentery, or chronic gastritis. A gastric fluid test should be performed in both cases. Indigestion and diarrhea can also occur due to insufficient gastric acid. Generally, the diagnosis cannot be made clearly based on symptoms alone, and a gastroscopy is required to confirm the diagnosis. In terms of treatment, hypochlorhydria is usually treated mainly to protect the gastric mucosa.

Those with low gastric acid should try not to drink water before and after meals, otherwise it will dilute the gastric acid and make digestion worse.
