After pituitary tumor surgery, the growth hormone can not be lowered, can be treated with medication, radiotherapy, and if necessary, surgery again. 1. Drug treatment: bromocriptine is commonly used in clinic to help reduce the hormone level of patients, it is a kind of dopamine agonist, and the drug should be used under the guidance of doctor, and should not be used by oneself. 2. Radiotherapy: If the tumor grows complicatedly and invades the surrounding brain tissue and neurovascular, it may be difficult to remove the tumor completely by surgery, and then the growth hormone level may also be increased after surgery, and radiotherapy can be carried out under the guidance of doctor. 3. Surgical resection of tumor again: if the tumor recurs or the residual tumor is too much, it can cause the growth hormone not to fall down after surgery, and need to be treated by surgery again. If patients find that the growth hormone level does not drop after surgery for pituitary tumor, they need to improve the relevant examination in time and actively cooperate with doctors for treatment, so as not to affect the further development of the disease and cause serious consequences.
