Low triglycerides and cholesterol may be caused by dietary factors, liver disease, etc. The harm is related to the cause of the disease, such as caused by liver disease, there may be anorexia, anemia, muscle weakness and so on. 1. Dietary factors: If you eat less meat, oil and fat in your normal life, and eat a light diet, you may have low triglyceride and cholesterol, which generally will not cause too much harm to your body, and it is recommended that you have a balanced diet, so that your triglyceride and cholesterol can be restored to their normal values. 2. Liver diseases: Serious liver diseases such as tuberculosis and liver cancer may affect the metabolic function of liver cells, causing insufficient bile secretion and symptoms of lipid malabsorption, resulting in lower triglycerides and cholesterol. As a result, symptoms such as aversion to fat diet, anemia, muscle weakness, and skin atrophy and dryness may occur. 3. Hyperthyroidism: In patients with hyperthyroidism, due to excessive synthesis of thyroid hormones, the body’s metabolism is enhanced and hypermetabolic syndrome occurs, so the patient may have a decrease in triglycerides and cholesterol, which in turn leads to a lack of energy. It is recommended that patients with lowered triglycerides and cholesterol go to a regular hospital to find out the cause of the problem and have it treated.
