As the pregnancy progresses, after the middle stage, the changes of various hormone levels in the body will be very obvious, thus producing some physiological changes. The fetus continues to grow and press on the abdominal cavity, which may lead to symptoms such as lack of sleep and depression at night, and in the long run, tinnitus will appear. If tinnitus lasts for a short period of time and does not affect sleep much, it can be treated without special treatment. If tinnitus lasts for more than two hours and brings about irritability and restlessness, it needs to be treated with drug intervention. These drugs have no teratogenic effect and can be taken orally as appropriate.
