How should hyper mucus secretion be diagnosed? Abnormal mucus hypersecretion in the thyroid gland is also called hyperthyroidism. Typical hyperthyroidism has symptoms such as hypermetabolic symptoms, enlarged thyroid gland and protruding eyes, which are not difficult to diagnose. However, about 20% of hyperthyroid patients have atypical clinical manifestations, mostly in the elderly, older patients, patients with chronic diseases or patients with early and mild hyperthyroidism, with atypical symptoms and signs, often without protruding eyes and an inconspicuous enlarged thyroid gland, especially some patients with insidious hyperthyroid symptoms and The common atypical manifestations are as follows: 1. Cardiovascular type: cardiovascular symptoms, tachycardia, arrhythmia, angina pectoris or heart failure are the prominent symptoms. 2, neurological type: neuropsychiatric symptoms as the prominent manifestation, the patient’s hypersensitivity, inattention, emotional impatience, fidgeting, insomnia, hallucinations, mostly seen in women, easily misdiagnosed as neurosis or menopausal syndrome. 3, gastrointestinal type: often with diarrhea as the prominent symptom stool several times a day or even dozens of watery diarrhea. No pus and blood stools, often misdiagnosed as enteritis, chronic colitis. 4.Muscle type: muscle weakness, loss of strength and cycle paralysis as the prominent manifestation, often without protruding eyes, no hyperthyroidism signs and symptoms such as goiter, or symptoms appear later, mostly seen in middle-aged men, mostly occurring after the patient has a full meal and intake of large amounts of sugar-based foods. 5, cachexia type: with wasting as the prominent symptom, rapid weight loss, muscle atrophy, subcutaneous fat reduction or disappearance, and even cachexia, often misdiagnosed as malignant tumor, mostly seen in elderly patients.
