Low growth hormone can be supplemented with increased nutrition or growth hormone replacement therapy depending on the condition. The first step is to determine the cause of the low growth hormone level and treat the cause accordingly. 1. If the low growth hormone level is caused by poor nutrition, it can be supplemented by increasing nutrition, such as increasing lean meat, fish, eggs, milk and other highly nutritious food, and at the same time, increasing physical exercise to enhance physical fitness. 2. If the low growth hormone level is caused by pituitary dysplasia, birth injury, cranial trauma and other diseases, and the supplementation effect cannot be achieved through food treatment, recombinant human growth hormone replacement therapy may be needed. Recombinant Human Growth Hormone Replacement Therapy should be used with caution or contraindicated in patients with malignant tumors or potential malignant changes in tumors and in patients with severe diabetes mellitus. Low growth hormone should be treated in a hospital, and the doctor should determine the correct method of supplementation according to the specific condition.
