There are many causes of chills all over the body. In addition to this physiological reaction during the season when it is too cold, it can also be caused by a disease state. The most common is an infection that causes the body temperature to rise and a generalized chill to occur. Other diseases can also cause chills, such as anemia, of which chronic bleeding hemorrhoids and excessive menstruation are the most common. You can eat more iron-rich foods, such as spinach and lean meat, and you can also eat more aconite and red dates to help correct anemia. In severe cases, ferrous fumarate can also be taken orally to correct anemia. In addition, hypothyroidism can also cause chills all over the body. This is due to a decrease in the basal metabolic rate of the body after hypothyroidism, which results in poor blood circulation in the peripheral parts of the body and leads to chills. Most of the time, the condition can be gradually improved and relieved after taking oral levothyroxine sodium tablets to correct the thyroid function. People with low blood pressure are also prone to chills and need to actively control the symptoms of low blood pressure. In addition, certain liver diseases and cardiovascular diseases can also cause chills. Further examinations, such as liver ultrasound, liver function, electrocardiogram, and cardiac ultrasound, are needed to identify the specific cause of the disease and to give appropriate treatment in order to achieve good relief. The cause of liver pathogenesis is mainly due to the failure of normal metabolism and energy production disorders. Cardiovascular diseases, on the other hand, are due to blood disorders and poor peripheral circulation, resulting in chills in the body.
