Why do I feel anxious for no apparent reason?

Generally, unexplained anxiety may be caused by hormonal fluctuations, accumulated stress, generalized anxiety disorder, panic disorder, hyperthyroidism, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Hormonal fluctuations: During special periods such as puberty, menstruation, or pregnancy, changes in estrogen and progesterone levels can easily trigger anxious emotions. Maintaining regular sleep patterns and avoiding late nights, along with eating more nutrient-rich foods like soy products and nuts, can help stabilize hormone levels.

2. Accumulated stress: Long-term hidden stress that is not released in time can gradually lead to persistent feelings of anxiety. Reserving half an hour daily for exercise such as jogging or yoga, or expressing emotions through journaling, can effectively relieve stress.

3. Generalized anxiety disorder: Characterized by persistent excessive worry, often accompanied by symptoms such as palpitations and insomnia. Patients may take medications such as buspirone hydrochloride tablets, tandospirone citrate capsules, or lorazepam tablets according to medical advice, along with psychological counseling.

4. Panic disorder: Manifests as sudden, intense anxiety attacks, accompanied by physical symptoms such as chest tightness and nausea. Medications such as alprazolam tablets, paroxetine hydrochloride tablets, or sertraline tablets should be taken as prescribed, while learning breathing relaxation techniques to manage episodes.

5. Hyperthyroidism: Excessive secretion of thyroid hormones accelerates metabolism, leading to symptoms such as anxiety and excessive sweating. Medications such as methimazole tablets, propylthiouracil tablets, or metoprolol tartrate tablets may be used under medical supervision. If medication is ineffective, subtotal thyroidectomy—removing part of the thyroid tissue to reduce hormone secretion—may be considered.

In daily life, avoid excessive consumption of stimulants such as coffee and strong tea. Communicate regularly with family and friends to create a relaxed social environment, and cultivate hobbies such as painting or gardening to divert attention.
