Mucus hypersecretion refers to the secretion of more mucus than normal, usually due to hyper-secretion of mucus glands caused by certain bacterial infections, etc. It is associated with spleen deficiency and glandular imbalance. See if there are any thyroid abnormalities. The common causes of mucus hypersecretion are as follows: 1. Exposure to allergens Allergens are also known as sensitizers or allergens. Among them, allergens for the common term, allergens or allergens for medical terms, refers to the antigens that can make people allergic. Their common characteristic is that the body is sensitized after a certain period of exposure to the allergen. The duration of the sensitization period can be long or short, there are no clinical symptoms during this period, and only after re-exposure to the allergen, an allergic reaction can occur. 2, the infection of bacteria and their toxins bacterial infection, the body’s immune response can be divided into non-specific immune response and specific immune response, the latter can be divided into two aspects of cellular and humoral immunity. When the body’s immune function decreases, it cannot give full play to its role of phagocytosis and killing bacteria, even if the amount of invading bacteria is small and pathogenic is not strong, it can also cause infection; medical infections caused by conditionally pathogenic bacteria are gradually increasing. Clinically, some patients may also experience irritability, cold and cyanosis of the extremities, rapid pulse, increased respiration, and decreased blood pressure. Especially in the elderly, children, those with chronic diseases or immune deficiency, those with untimely treatment and complications, sepsis or septicemia may develop. 3, physical environmental factors such as hot and cold changes, temperature imbalance, endocrine disorders or imbalance of acid-base balance of body fluids and other causes can cause the disease. It can also be due to the simultaneous or sequential existence of multiple factors.
