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. Look for abnormalities in the thyroid gland. Mucus glands are generally referred to as exocrine glands that secrete mucus. They are composed of one or more mucus cells, as opposed to plasma glands. They are widely distributed in plants and animals, and in higher animals they are found in the mouth, nasal cavity, trachea, esophagus, stomach, intestines, excretory organs, etc. They are involved in the formation of mucus. Etiology of mucus hypersecretion: pretibial myxedema Pretibial myxedema (pretibial myxedema), also known as thyrotoxic mucin deposition, is characterized by the presence of well-defined firm edematous plaques or nodules in the pretibial area, often associated with thyrotoxicosis. Clinical manifestations include lesions most commonly in the anterior tibial region, often associated with hyperthyroidism and proptosis. Drumstick-like digits. Pseudomyxoma peritonei (PMP) is a low-grade malignant mucinous tumor occurring in the peritoneal wall layers, greater omentum, and plasma surface of the intestinal wall. The incidence is low, with a higher incidence in women than in men, mostly in middle age or old age. It is easy to recur after treatment and is one of the more difficult diseases in clinical practice. Cutaneous myxomas are solitary, flesh-colored nodules that occur on the face, trunk, or extremities. Cutaneous myxomas can also be a symptom of Carney syndrome, in which cutaneous myxomas are multiple skin-colored papules less than 1 cm in size.
