Patients with hypothyroidism will show symptoms of chills rather than a fear of heat. Hypothyroidism is a condition in which there is a decrease in the production of thyroid hormones. Thyroid hormone is a thermogenic hormone that increases energy consumption, so patients with hyperthyroidism may exhibit hypermetabolic symptoms such as thermophobia, clammy skin, and excessive sweating. Patients with hypothyroidism have a decrease in thyroid hormones and may exhibit low metabolic symptoms such as chills, lethargy, drowsiness, fatigue, unresponsiveness, hoarseness, bloating and constipation. Patients with hypothyroidism will also have hypercholesterolemia due to the decrease in cholesterol breakdown. People with chronic diseases are prone to atherosclerosis and coronary heart disease, and some elderly patients and people who have not been treated for a long time will be prone to mucous edema in winter, or even mucous edema coma.
