What is the reason for low thyroid hormone

Some people find out that they have low thyroid hormone when they go to the hospital for a check-up, but they don’t have any disease. What’s going on? What causes low thyroid hormone? In fact, low thyroid hormone is sometimes not a disease. Bad mood and improper diet can cause low thyroid hormone. But sometimes thyroid diseases can also cause low thyroid hormone. Patients must distinguish them.

Hypothyroidism is a clinical syndrome caused by insufficient synthesis, secretion or biological effect of thyroid hormone due to various reasons, leading to decreased metabolic activity in the body.

Traditional Chinese medicine believes that the occurrence of this disease is often related to the following factors.

1. Emotional stimulation: Mental stimulation can lead to liver qi stagnation, which can cause spleen deficiency, leading to disordered transportation and transformation, and endogenous dampness and phlegm; or spleen deficiency and weak qi, deficiency of vital energy, and inability of qi to lead blood, leading to qi deficiency and blood stasis, phlegm and blood stasis, obstruction of meridians, and poor blood and water flow, resulting in symptoms such as edema and amenorrhea.

2. Improper diet: Improper diet damages the spleen and stomach, resulting in insufficient Qi in the middle, disordered transportation and transformation, inability to transport and transform food and water, and internal generation of phlegm and dampness. Excessive phlegm and dampness block the Qi flow and damage the spleen Yang. The spleen is the foundation of acquired constitution. If spleen yang is weak, the kidney fire will be nourished over time, resulting in deficiency of both spleen and kidney, and symptoms such as loss of appetite, fear of cold and cold limbs, drowsiness, laziness, and general edema will appear.

3. Invasion of external evil: Most of the time, wind, heat and toxic evil invade from the mouth and nose. The toxic evil gathers in the front of the neck, causing swelling and pain in the throat and front of the neck. If cold things are used excessively, the internal Yang Qi will be injured. Although the heat and toxins in the neck are eliminated and the pain disappears, symptoms such as low voice, fear of cold, and even edema may be seen.

4. Surgical treatment or drug poisoning: Due to thyroidectomy or taking certain toxic drugs (such as Western medicine for treating hyperthyroidism), the body's vital energy is damaged, resulting in malnutrition of internal organs and functional decline, which can manifest as a series of deficiency symptoms.

The key to the course of this disease is the deficiency of Yang Qi. The kidney is the foundation of the innate constitution and the residence of the true yang. All the yang in the five internal organs of the human body depends on the original strength in the kidney for its growth and development. The deficiency of true Yang leads to cold body and fatigue of mind, which is a sign of decline of Mingmen fire. However, the deficiency of thyroid hormone is the basic cause. Hormones are yin and sticky, so its pathology also involves insufficient kidney essence. The sign of yang deficiency is the pathological manifestation of "without yin, yang cannot be born", which is caused by yin disease involving yang. Some patients have symptoms such as dry and rough skin, constipation, and red tongue with little coating, which are also signs of insufficient Yin fluid. There may even be symptoms of deficiency of both kidney yin and yang.

In addition, when the kidney yang is deficient and cannot warm the spleen earth, the spleen yang also weakens, and the muscles lose nourishment, resulting in muscle weakness or limb muscle pain. The spleen is responsible for regulating blood. If the spleen is weak, blood will not be stored properly. Women may experience menstrual disorders, metrorrhagia, etc., often accompanied by anemia. When kidney yang is insufficient, heart yang is also unable to stimulate its activity, and symptoms of heart yang deficiency can be seen, with a deep or slow pulse being common. The whole body's warming function becomes worse, resulting in cold limbs, lowered body temperature, and even abnormal circulation of body fluids and blood, which gather to form dampness, fluid, and phlegm, resulting in swollen skin. In short, kidney deficiency is the main pathology of hypothyroidism, among which insufficient kidney essence is the fundamental cause and insufficient kidney yang is the key. The lesions often involve the heart and spleen, leading to spleen and kidney yang deficiency and heart and kidney yang deficiency.

The above has introduced the causes of low thyroid hormone. In fact, low thyroid hormone may not be a disease sometimes. It is just because the patient is not paying attention to his daily living and eating habits, or it is caused by repeated emotions. But this is not the case, so everyone still needs to go for a physical examination to know.
