What illness causes elderly people to constantly sigh and groan?

 　　Persistent sighing in elderly individuals may be caused by conditions such as bronchitis, neurosis, or anxiety disorder. Specific details are as follows:
　　1. Bronchitis
　　This typically refers to an inflammation of the mucous membranes of the trachea and bronchi and surrounding tissues, often associated with recurrent viral or bacterial infections. Frequent sighing may occur, and treatment may include medications such as erythromycin capsules, penicillin capsules, or ambroxol oral solution, taken as directed by a physician.
　　2. Neurosis
　　When exposed to external stressors or under significant pressure that is difficult to adapt to, the central nervous system's balance between excitation and inhibition may be disrupted, leading to dysregulation of the autonomic nervous system and resulting cardiovascular disturbances, which may manifest as excessive sighing. Treatment may involve medications such as nifedipine tablets or nitroglycerin tablets, used according to medical advice.
　　3. Anxiety Disorder
　　This is typically a mental health condition characterized by episodic or persistent feelings of anxiety, tension, and fear, often accompanied by autonomic nervous system dysfunction, which may lead to the aforementioned symptoms. Treatment may include medications such as sertraline hydrochloride tablets, venlafaxine hydrochloride sustained-release capsules, or idebenone tablets, used under a doctor's guidance.
　　In addition to the above causes, conditions such as bronchiectasis, coronary atherosclerotic heart disease, or heart failure may also be responsible. It is recommended to seek timely medical evaluation.
