The symptoms of thyroid nodules, hyperthyroidism and hypothyroidism all belong to the scope of “gall disease” and “Chinese disorders” in Chinese medicine, and are distinguished as follows: Thyroid nodules Thyroid (also called thyroid nodules and thyroid tumors) is one of the common diseases in Lin Ma. The clinical distinction between thyroid nodules and thyroid tumors depends mainly on the size. A thyroid nodule larger than one centimeter is a tumor, while a nodule smaller than one centimeter is a nodule. When it comes to tumors, the first thing people think about is whether they are benign or malignant. Thyroid tumors are usually benign tumors, so don’t get too nervous. Benign: Most neck lumps are single, slow growing, and may have pressure symptoms when large. The lumps move up and down with swallowing, are smooth, soft, round or oval in texture, and can cause hyperthyroidism. Malignant: hard texture. Symptoms of thyroid: Patients have enlargement in the front of the neck below the laryngeal node, increased meal size, increased number of meals, and also often feel hungry, with repeated failure to eat, along with weight loss. Gender and thyroid function: Because thyroid disease is more common in women, it is usually more complicated in men than in women. Hyperthyroidism Hyperthyroidism is one of the most common clinical thyroid disorders and its symptoms are basically the same as those of thyroid nodules. The difference is that a thyroid nodule (tumor) is an enlargement of the front of the neck below the laryngeal nodes, while hyperthyroidism is a bulging of the eyeballs. Hypothyroidism Hypothyroidism is an endocrine disorder in which the thyroid gland is hypofunctional and synthesizes and secretes less thyroid hormone. It can develop at any age. The thyroid gland is located in the front of the neck below the laryngeal node and has a butterfly shape; in fact, all metabolic processes in the body are influenced by thyroid hormones. The onset of hypothyroidism in adulthood is severe and is called mucinous edema. Patients are mostly 40-60 years old and typically present with slow movements, mental atrophy, memory loss, fear of cold, no sweating, and constipation. Facial swelling of the cheeks and eyelids, pallor, rough skin, dry fur loss, slow speech, low tone, etc. can be seen. Especially severe cases may cause mucus edema coma.
