What causes sudden palpitations upon waking up in the morning?

Waking up in the morning with sudden palpitations may have several possible causes: 1. Physiological factors: After waking in the morning, increased sympathetic nervous system activity may lead to a faster heart rate and palpitations. This condition is usually normal and does not require special treatment. Symptoms can be relieved with appropriate rest and drinking warm water. 2. Hypoglycemia: Upon getting up in the morning while fasting, palpitations may occur due to insufficient blood glucose levels. Timely food intake or sugar supplementation can alleviate symptoms. 3. Cardiac issues: Palpitations may be caused by heart conditions such as arrhythmia, cardiac neurosis, or coronary artery disease. These conditions may require medication or surgical treatment, and prompt medical evaluation is recommended. 4. Other factors: Morning palpitations may also be triggered by anemia, hypertension, autonomic nervous system dysfunction, or inadequate sleep during the night. Patients experiencing recurrent morning palpitations are advised to seek timely medical consultation, undergo appropriate diagnostic tests, identify the underlying cause, and receive targeted treatment.
